CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City 1: Perioperative Concepts and Nursing Managements Glossary Ambulatory Surgery – includes outpatient, same-day, or shortstay surgery that does not require an overnight hospital stay Bariatrics – having to do with patients who are obese Informed Consent – the patient’s autonomous decision about whether to undergo a surgical procedure, based on the nature of the condition, the treatment options, and the risks and benefits involved Intraoperative Phase – period of time that begins with transfer of the patient to the operating room area and continues until the patient is admitted to the postanesthesia care unit Minimally Invasive Surgery – surgical procedures that use specialized instruments inserted into the body either through natural orifices or through small incisions Perioperative Phase – period of time that constitutes the surgical experience; includes the preoperative, intraoperative, and postoperative phases of nursing care Postoperative Phase – period of time that begins with the admission of the patient to the post-anesthesia care unit and ends after follow-up evaluation in the clinical setting or home Preadmission Testing – diagnostic testing performed before admission to the hospital Preoperative Phase – period of time from when the decision for surgical intervention is made to when the patient is transferred to the operating room table Perioperative Nursing Communication, teamwork, and patient assessment are crucial to ensure good patient outcomes in the perioperative setting. Perioperative nursing, which spans the entire surgical experience, consists of three phases that begin and end at particular points in the sequence of surgical experience events. Surgery can also be classified based upon the degree of urgency involved: emergent, urgent, required, elective, and optional Surgery which needs to be done in order to retain quality of life Special Populations: o Elderly Patients o Obese Patients o Patients with Disabilities Preoperative Nursing It begins with informed consent (a patient’s autonomous decision about whether to undergo a surgical procedure). PreOp assessment focuses on the prevention of complications: o Nutritional and Fluid Status o Dentition o Drug and Alcohol Use o Cardiovascular and Respiratory Status o Hepatic and Renal Function o Endocrine and Immune Function o Medications o Psychosocial and Cultural Factors Quality and Safety Nursing Alert A latex allergy can manifest as a rash, asthma, or anaphylactic shock. The possible adverse interactions of some medications require the nurse to assess and document the patient’s use of prescription medications, OTC medications (especially aspirin), herbal agents, and the frequency with which medications are used. The nurse must clearly communicate this information to the anesthesiologist or CRNA Nursing Management Choose an appropriate time and place for preoperative teaching. Address deep-breathing and coughing, postoperative mobility, pain management. Teach the patient about preoperative fasting. Prepare the patient’s bowels and skin as ordered. Administer preoperative medications. Meticulous documentation is necessary Intraoperative Nursing Glossary Anesthesia – a state of narcosis or severe central nervous system depression produced by pharmacologic agents Stepanie Bryn O.

CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City Anesthesiologist – physician trained to deliver anesthesia and to monitor the patient’s condition during surgery Anesthetic Agent – the substance, such as a chemical or gas, used to induce anesthesia circulating nurse (or circulator): registered nurse who coordinates and documents patient care in the operating room Laparoscope – a thin endoscope inserted through a small incision into a cavity or joint using fiber-optic technology to project live images of structures onto a video monitor; other small incisions allow additional instruments to be inserted to facilitate laparoscopic surgery Malignant Hyperthermia – a rare life-threatening condition triggered by exposure to most anesthetic agents inducing a drastic and uncontrolled increase in skeletal muscle oxidative metabolism that can overwhelm the body’s capacity to supply oxygen, remove carbon dioxide, and regulate body temperature, eventually leading to circulatory collapse and death if untreated; often inherited as an autosomal dominant disorder Moderate Sedation – previously referred to as conscious sedation, involves the use of sedation to depress the level of consciousness without altering the patient’s ability to maintain a patent airway and to respond to physical stimuli and verbal commands Monitored Anesthesia Care – moderate sedation given by an anesthesiologist or certified registered nurse anesthetist (CRNA) Registered Nurse First Assistant – a member of the operating room team whose responsibilities may include handling tissue, providing exposure at the operative field, suturing, and maintaining hemostasis Restricted Zone – area in the operating room where scrub attire and surgical masks are required; includes operating room and sterile core areas Scrub Role – registered nurse, licensed practical nurse, or surgical technologist who scrubs and dons sterile surgical attire, prepares instruments and supplies, and hands instruments to the surgeon during the procedure Semi-Restricted Zone – area in the operating room where scrub Sattire is required; may include areas where surgical instruments are processed Surgical Asepsis – absence of microorganisms in the surgical environment to reduce the risk of infection Unrestricted Zone – area in the operating room that interfaces with other departments; includes patient reception area and holding area The Surgical Environment Surgical environment is known for its stark appearance and cool temperature. Surgical asepsis is paramount in the OR. o A “zone” system is used with appropriate environmental controls o Appropriate attire Safety issues include exposure to blood and body fluids, and exposure to latex and adhesive substances, radiation, and toxic agents and lasers. Types of Anesthesia and Sedation General Anesthesia Regional Anesthesia Local Anesthesia Moderate Sedation (Monitored Anesthesia Care) Routes of General Anesthesia Inhalation o Inhaled anesthetic agents include volatile liquid agents and gases. Volatile liquid anesthetic agents produce anesthesia when their vapors are inhaled. o When inhaled, the anesthetic agents enter the blood through the pulmonary capillaries and act on cerebral centers to produce loss of consciousness and sensation o The vapor from inhalation anesthetic agents can be given to the patient by several methods. LMA (Laryngeal Mask Airway) – a flexible tube with an inflatable silicone ring and cuff that can be inserted into the larynx ETT (Endotracheal Tube) – The endotracheal technique for administering anesthetic medications consists of introducing a soft rubber or plastic ETT Stepanie Bryn O.

CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City into the trachea, usually by means of a laryngoscope. The ETT may be inserted through either the nose or mouth. Intravenous Administration o General anesthesia can also be produced by the IV administration of various anesthetic and analgesic agents, such as barbiturates, benzodiazepines, nonbarbiturate hypnotics, dissociative agents, and opioid agents. o An advantage of IV anesthesia is that the onset of anesthesia is pleasant; there is none of the buzzing, roaring, or dizziness known to follow administration of an inhalation anesthetic agent. o The combination of IV and inhaled anesthetic agents produces an effective and smooth experience for the patient, with a controlled emergence following surgery Regional Anesthesia o In regional anesthesia, an anesthetic agent is injected around nerves so that the region supplied by these nerves is anesthetized. o The effect depends on the type of nerve involved: Motor Fibers are the largest fibers and have the thickest myelin sheath. Sympathetic Fibers are the smallest and have a minimal covering. Sensory Fibers are intermediate. o Examples of Common Local Conduction Blocks Brachial Plexus Block – which produces anesthesia of the arm Paravertebral Anesthesia – which produces anesthesia of the nerves supplying the chest, abdominal wall, and extremities Transsacral (Caudal) Block – which produces anesthesia of the perineum and, occasionally, the lower abdomen Moderate Sedation o Previously referred to as conscious sedation, is a form of anesthesia that involves the IV administration of sedatives or analgesic medications to reduce patient anxiety and control pain during diagnostic or therapeutic procedures. o The goal is to depress a patient’s level of consciousness to a moderate level to enable surgical, diagnostic, or therapeutic procedures to be performed while ensuring the patient’s comfort during and cooperation with the procedures Monitored Anesthesia Care o Also referred to as monitored sedation, is moderate sedation given by an anesthesiologist or CRNA who must be prepared and qualified to convert to general anesthesia if necessary Local Anesthesia o Injection of a solution containing the anesthetic agent into the tissues at the planned incision site. o o Local anesthesia is often given in combination with epinephrine. Local anesthesia is the preferred anesthetic method in any surgical procedure. Quality and Safety Nursing Alert It is the responsibility of all nurses, and particularly perianesthesia and perioperative nurses, to be aware of latex allergies, necessary precautions, and products that are latex free. Hospital staff are also at risk for development of a latex allergy secondary to repeated exposure to latex products. Postoperative Nursing Glossary Dehiscence – partial or complete separation of wound edges Evisceration – protrusion of organs through the surgical incision First-Intention Healing – method of healing in which wound edges are surgically approximated and integumentary continuity is restored without granulation Phase I PACU – area designated for care of surgical patients immediately after surgery and for patients whose condition warrants close monitoring Phase II PACU – area designated for care of surgical patients who have been transferred from a phase I PACU because their condition no longer requires the close monitoring provided in a phase I PACU Phase III PACU – setting in which the patient is cared for in the immediate postoperative period and then prepared for discharge from the facility Postanesthesia Care Unit (PACU) – area where postoperative patients are monitored as they recover from anesthesia; formerly referred to as the recovery room or postanesthesia recovery room Second-Intention Healing – method of healing in which wound edges are not surgically approximated and integumentary continuity is restored by the process known as granulation Third-Intention Healing – method of healing in which surgical approximation of wound edges is delayed and integumentary continuity is restored by opposing areas of granulation. Postoperative Period The postoperative period extends from the time the patient leaves the operating room (OR) until the last follow-up visit with the surgeon. This may be as short as a day or two or as long as Stepanie Bryn O. Agustero BSN 3A 3|P a g e N o v. 2 0 , 2 0 2 3 Republic of the Philippines Province of Zamboanga del Sur J.H. CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City several months. During the postoperative period, nursing care focuses on re-establishing the patient’s physiologic equilibrium, alleviating pain, preventing complications, and educating the patient about self-care. Frequent skilled nursing assessment is necessary. o Focuses on the risks of impaired respirations, cardiovascular instability, haemorrhage, unstable BP, shock When stable, the patient is discharged home or discharged to the postoperative unit. Nursing Management in the PACU Utilized the nursing process Frequent, thorough assessment is necessary Interventions focus on: o Respiratory Function The primary objective in the immediate postoperative period is to maintain ventilation and thus prevent hypoxemia and hypercapnia. Both can occur if the airway is obstructed and ventilation is reduced (hypoventilation). Patients who have experienced prolonged anesthesia usually are unconscious, with all muscles relaxed. This relaxation extends to the muscles of the pharynx. When the patient lies on their back, the lower jaw and the tongue fall backward and the air passages become obstructed. This is called hypopharyngeal obstruction o Promoting Cardiac Output The primary cardiovascular complications seen in the PACU include hypotension and shock, hemorrhage, hypertension, and dysrhythmias. Hypotension can result from blood loss, hypoventilation, position changes, pooling of blood in the extremities, or side effects of medications and anesthetics. Shock which is one of the most serious postoperative complications, can result from hypovolemia and decreased intravascular volume. Types of Schock Hypovolemic Shock – Most common type Cardiogenic Shock Neurogenic Shock Anaphylactic Shock Septic Shock Relieving Pain Encouraging Activity Wound Healing (Dressing Changes) o Wound healing mechanisms (see glossary) First intension healing Second intention healing Third intention healing Nutrition and GI Function Managing Potential Complications Venous Thromboembolism Hematoma Infection (Wound Sepsis) Wound Dehiscence and Evisceration. Discharge Teaching Should begin as early as possible Because of earlier discharges than in the past, discharge teaching must be comprehensive 2: Chronic Illness Glossary Chronic Disease – medical or health problem with associated symptoms or disabilities that require long-term management; also referred to as non-communicable disease, chronic condition, or chronic disorder Chronic Illness – the experience of living with a chronic disease or condition; the person’s perception of the experience and the person’s and others’ responses to the chronic disease or condition Cognitive Disability – limitations in mental functioning and difficulties with communication, self-care, and social skills Developmental Disability – a set of heterogeneous disorders characterized by difficulties in one or more domains; can include cognitive, physical, or both cognitive and physical impairments with an onset before 22 years of age Disability – restriction or lack of ability to perform an activity in a normal manner; the consequences of impairment in terms of a person’s functional performance and activity—disability represents impairment at the level of the person (e.g., bathing, dressing, communication, walking, grooming) Intellectual Disability – a disability that occurs before 18 years of age characterized by significant limitations in both intellectual functioning and in adaptive behavior, which includes many everyday social and practical skills Multiple Chronic Conditions (MCC) – presence of more than one chronic disease or condition Stepanie Bryn O. Agustero BSN 3A 4|P a g e N o v. 2 0 , 2 0 2 3 Republic of the Philippines Province of Zamboanga del Sur J.H. CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City Non-communicable Diseases – a group of conditions that are not caused by an acute infection Secondary Health Conditions or Disorders – any physical, mental, or social disorders resulting directly or indirectly from an initial disabling condition Sensory Disability – a disorder characterized by impairment of the sense of sight, hearing, smell, touch, or taste (e.g., hearing loss, deafness, vision loss, blindness) Psychiatric Disability – is defined as a mental illness or impairment that substantially limits one’s ability to complete major life activities, such as learning, working, and communicating. Many people with disabilities are at risk for secondary health conditions (e.g., pressure injuries, urinary tract infections, low bone density, depression) because of a narrow margin of health. Chronic Disease and Chronic Illness Chronic Disease refers to non-communicable diseases (conditions not caused by an acute infection or injury), chronic conditions, or chronic disorders. Chronic Illness refers to the human experience of living with a chronic disease or condition. Includes the person’s perception of the experience of having a chronic disease or condition and the person’s and others’ responses to it, including health care professionals… Only the person and the family really know what it is like to live with chronic illness. (Larsen, 2019). Having multiple chronic conditions (MCC) increases the complexity of care. Thus, patients with MCC are at risk for conflicting medical advice, adverse effects of medications, unnecessary and duplicative tests, and preventable hospitalizations, all of which can negatively affect their health (CDC, 2019b). Chronic diseases or conditions are often defined as medical conditions or health problems with associated symptoms or disabilities that require long-term management. Definitions of chronic disease or chronic illness share the characteristics of being irreversible, having a prolonged course, and remaining unlikely to resolve spontaneously The main Social Determinants of Health (SDOH) that have been identified include income and social status, employment and working conditions, education and literacy, childhood experiences, physical environment, social supports and coping skills, healthy behaviors, access to health services, biology and genetic makeup, gender, culture, race and ethnicity. Prevention of Chronic Disease Risk Factors o Hypertension (high blood pressure) o Tobacco and ENDS use or exposure to secondhand smoke o Overweight or obesity (high BMI) o Lack of physical activity o Excessive alcohol use o Consumption of diets low in fruits and vegetables o Consumption of food high in sodium and saturated fats Characteristics of Chronic Conditions Psychological and Social Issues: Associated psychological and social issues must also be addressed, because living for long periods with illness symptoms and disability can threaten identity, bring about role changes, alter body image, and disrupt lifestyles, work, and family life. Course of Chronic Disease: Chronic health conditions usually involve many different phases over the course of a person’s lifetime. There can be acute periods, stable and unstable periods, flare-ups, and remissions. Progression of Chronic Disease: The rate of progression of chronic diseases can vary from a rapid downhill course leading quickly to disability and death within a few months of onset to those with a slow downhill progression over years. Therapeutic Regimens: Keeping chronic conditions under control requires persistent adherence to therapeutic regimens that may be complex and may interfere with usual activities or even life goals. Failing to adhere to a treatment plan or to do so consistently increases the risks of developing complications and accelerating the disease process. Development of other Chronic Conditions: One chronic disease can lead to the development of other chronic conditions. Family Life: Chronic illness affects the entire family. Family life can be dramatically altered as a result of role reversals, unfilled roles, loss of income, time required to manage the illness, decreases in family socialization activities, and the costs of treatment. Home Life: The day-to-day management of illness is largely the responsibility of people with chronic disorders and their families. Self-Management: The management of chronic conditions is a continual process. People can be taught how to manage their conditions. Collaborative Process: Managing chronic conditions must be a collaborative process that involves many different health care professionals working together with patients and their families to Stepanie Bryn O. Agustero BSN 3A 5|P a g e N o v. 2 0 , 2 0 2 3 Republic of the Philippines Province of Zamboanga del Sur J.H. CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City provide the services and supports that are often needed for management at home. Health Care Costs: The management of chronic conditions is expensive. Many expenses incurred by an individual patient (e.g., costs for hospital stays, diagnostic tests, equipment, medications, and supportive services) may be covered by health insurance and by federal and state agencies. The Patient Protection and Affordable Care Act (ACA), passed in 2010, the most significant change to health care policy in the United States since the establishment of Medicare and Medicaid, has made available health insurance for many previously uninsured individuals who were unable to obtain health insurance. Lost Income: If a family’s primary income earner becomes ill, chronic diseases can result in drastic loss in income with inadequate funds for food, education, and health care. Living with Uncertainty: Having a chronic illness means living with uncertainty. Although health care providers may be aware of the usual progression of a chronic disease such as Parkinson’s disease or multiple sclerosis, no one can predict with certainty the course of a person’s illness. Even when a patient is in remission or symptom free, the person often fears that symptoms will reappear. Implications of Managing Chronic Conditions Once a chronic condition has occurred, the focus shifts to managing symptoms, avoiding complications (e.g., eye complications in a person with diabetes), and preventing other acute illnesses (e.g., pneumonia in a person with chronic obstructive lung disease). Quality of life—often overlooked by health care professionals in their approach to people with chronic conditions— is also important. Health-promoting behaviors, such as exercise, are essential to quality of life even in people who have chronic illnesses or disabilities, because it helps maintain functional status (Larsen, 2019). The need to deal with more than one chronic condition at a time. The symptoms or treatment of a second chronic condition may aggravate the first chronic condition. The need to hire and oversee caregivers who come into their homes to assist with ADLs and IADLs Nursing Care of Patients with Chronic Conditions Nursing care of patients with chronic conditions is varied and occurs in a variety of settings. Care may be direct or supportive Types of Care Direct may be provided in the clinic or primary care provider’s office, a nursemanaged center or clinic, a hospital, long-term care facility, or the patient’s home. includes assessing the patient’s physical status, providing wound care, managing and overseeing medication regimens, providing education to the patient and family, and performing technical tasks Supportive may include ongoing monitoring, education, counseling, serving as an advocate for the patient, making referrals, and case management. Home, Community-Based, and Transitional Care Educating Patients About Self-Care o Well-informed, educated patients are more likely than uninformed patients to be concerned about their health and do what is necessary to maintain it. They are also more likely to manage symptoms, recognize the onset of complications, and seek health care early o The nurse cannot assume that patients with a long-standing chronic condition have the knowledge necessary to manage the condition. o The nurse must also recognize that patients may know how their body responds under certain conditions and how best to manage their symptoms. Continuing and Transitional Care o Most chronic conditions are managed in the home. Therefore, care and education during hospitalization should focus on essential information about the condition so that management can continue once the patient is discharged home. o The home health nurse reassesses how the patient and the family are adapting to the chronic condition and its treatment and continues or revises the plan of care accordingly o Telehealth or telehomecare (use of electronic data and telecommunications technologies to support long-distance clinical health care, patient and professional health-related education, public health, and health administration) has been used effectively to provide care for patients with chronic illness. o Transitional care, if available, should be considered and implemented when the patient has MCC, has impaired cognitive status as well as physical limitations, has complex therapies, or is frail or unstable prior to discharge from the hospital to home. o Transitional care nurses serve as the primary coordinator of care. These nurses conduct assessments of the patient as well as the family caregivers’ ability to assist in management of the patient in the home. Nursing Care for Special Populations with Chronic Illness o When providing care and education, the nurse must consider multiple factors (e.g., age; gender; culture and ethnicity; cognitive status; the presence of physical, sensory, and cognitive limitations; health literacy) that influence susceptibility to chronic illness and the ways patients respond to chronic disorders. o Populations at high risk for specific conditions can be targeted for special education and monitoring programs; this includes those at risk because of their genetic profile o It is important to consider the effect of a preexisting disability, or a disability associated with recurrence of a chronic condition, on the patient’s ability to manage ADLs, self-care, and the therapeutic regimen. 3: Pain Management Glossary Acute Pain – pain that results from tissue damage that generally abates as healing occurs; serves as a warning signal that something is wrong or needs attention Adjuvant Analgesic Agent – a substance or medication added to an analgesic medication regimen to improve analgesia (synonym: co-analgesic agent) Agonist – a medication that binds to an opioid receptor mimicking the way endogenous substances provide analgesia Agonist-Antagonist – a type of opioid (e.g., nalbuphine and butorphanol) that binds to the kappa opioid receptor site acting as an agonist (capable of producing analgesia) and simultaneously to the mu opioid receptor site acting as an antagonist (reversing mu agonist effects) Allodynia – pain due to a stimulus that does not normally provoke pain, such as touch; typically experienced in the skin around areas affected by nerve injury and commonly seen with many neuropathic pain syndromes Antagonist – a medication that competes with agonists for opioid receptor binding sites; can displace agonists, thereby inhibiting their action Breakthrough Pain – a transitory increase in pain that occurs in the context of otherwise controlled persistent pain Ceiling Effect – an analgesic dose above which further dose increments produce no change in effect Central Sensitization – a key central mechanism of neuropathic pain; the abnormal hyperexcitability of central neurons in the spinal cord, which results from complex changes induced by the Stepanie Bryn O.

four to five half-lives are required to approach a steady-state level in the blood, irrespective of the dose, dosing interval, or route of administration; after four to five half-lives, a medication that has been discontinued generally is considered to be mostly eliminated from the body) Hydrophilic – a substance or medication that is readily absorbed in aqueous solution Hyperalgesia – an increasingly intense experience of pain resulting from a noxious stimulus Intraspinal “within the spine” – refers to the spaces or potential spaces surrounding the spinal cord into which medications can be given Lipophilic – a substance or medication that is readily absorbed in fatty tissues Metabolite – the product of biochemical reactions during medication metabolism Mu Agonist – any opioid that binds to the mu opioid receptor subtype and produces analgesic effects (e.g., morphine); used interchangeably with the terms full agonist, pure agonist, and morphinelike medication Multimodal Analgesia or Multimodal Pain Management – the intentional, concurrent use of more than one pharmacologic or nonpharmacologic intervention with different methods of action with the goal to achieve better analgesia while using lower doses of medications with fewer adverse effects Neuraxial – of the central nervous system Neuropathic (Pathophysiologic) Pain – pain caused by injury or dysfunction (lesion or disease) of one or more nerves of the peripheral or central nervous systems with resultant impaired processing of sensory input Neuroplasticity – the ability of the peripheral and central nervous systems to change both structure and function as a result of noxious stimuli Nociceptive (Physiologic) Pain – pain that is sustained by ongoing activation of the sensory system that conducts the perception of noxious stimuli; implies the existence of damage to somatic or visceral tissues sufficient to activate the nociceptive system Nociceptor – a type of primary afferent neuron that has the ability to respond to a noxious stimulus or to a stimulus that would be noxious if prolonged Nonopioid – refers to analgesic medications that include acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) NSAID – an acronym for nonsteroidal anti-inflammatory drug (pronounced “en said”) Opioid – refers to morphine and other natural, semisynthetic, and synthetic medications that relieve pain by binding to multiple types of opioid receptors; term is preferred to “narcotic” Opioid Dose–Sparing Effect – occurs when a nonopioid or coanalgesic medication is prescribed in addition to an opioid, enabling the opioid dose to be lower without diminishing analgesic effects Opioid-induced Hyperalgesia – a phenomenon in which exposure to an opioid induces increased sensitivity to pain, or a lowered threshold, to the neural activity conducting pain perception; it is the “flip side” of tolerance Opioid Naïve – denotes a person who has not recently taken enough opioid on a regular enough basis to become tolerant to the opioid’s effects Opioid Tolerant – denotes a person who has taken opioids long enough at doses high enough to develop tolerance to many of the opioid’s effects, including analgesia and sedation Pain – an unpleasant experience that is either emotional or sensory resulting from actual or possible damage to tissues and is uniquely experienced and described by each person Peripheral Sensitization – a key peripheral mechanism of neuropathic pain that occurs when there are changes in the number and location of ion channels; in particular, sodium channels abnormally accumulate in injured nociceptors, producing a lower nerve depolarization threshold, ectopic discharges, and an increase in the response to stimuli Physical Dependence – the body’s normal response to administration of an opioid for 2 or more weeks; withdrawal symptoms may occur if an opioid is abruptly stopped or an antagonist is given Placebo – any medication or procedure, including surgery, that produces an effect in a patient because of its implicit or explicit intent and not because of its specific physical or chemical properties Preemptive Analgesic Agents – pre-injury pain treatments (e.g., preoperative epidural analgesia and preincision local anesthetic infiltration) to prevent the development of peripheral and central sensitization of pain Refractory – nonresponsive or resistant to therapeutic interventions such as analgesic agents Substance Use Disorder (SUD) – problematic use of substances such as opioids, benzodiazepines, or alcohol based on identification of at least two of the diagnostic criteria listed by the American Psychiatric Association. It is characterized by craving the substance; continuing use despite harm; inability to stop using; and experiencing withdrawal symptoms when abruptly not using the substance; formerly known as addiction Titration – upward or downward adjustment of the amount (dose) of an analgesic agent Tolerance – a normal physiologic process characterized by decreasing effects of a medication at its previous dose, or the need for a higher dose of medication to maintain an effect Withdrawal – result of abrupt cessation or rapid decrease in dose of a substance upon which one is physically dependent. It is not necessarily indicative of substance use disorder Definition of Pain The American Pain Society (APS, 2016) defines pain as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage” This definition describes pain as a complex phenomenon that can impact a person’s psychosocial, emotional, and physical functioning. The clinical definition of pain reinforces that pain is a highly personal and subjective experience: “Pain is whatever the experiencing person says it is, existing whenever he says it does” Effects of Pain Pain is the primary reason people seek health care and one of the most common conditions that nurses treat Unrelieved pain has the potential to affect every system in the body and cause numerous harmful effects, some of which may last a lifetime Types and Categories of Pain Type of Pain According to Duration Acute Pain – involves tissue Chronic or Persistent Pain is damage as a result of surgery, subcategorized as being of trauma, burn, or venipuncture, cancer or noncancer origin and and is expected to have a can persist throughout the relatively short duration and course of a person’s life. resolve with normal healing.

CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City noxious stimuli (tissue injury) as the peripheral or central being painful. This is the reason nervous system (CNS) or both. why nociception is described as “normal” pain transmission. Subcategory of Chronic Pain o Noncancer Chronic Pain include peripheral neuropathy from diabetes, back or neck pain after injury, and osteoarthritis pain from joint degeneration. o Chronic pain may be intermittent, occurring with flares, or it may be continuous. Some conditions can produce both acute and chronic pain. For example, some patients with cancer have continuous chronic pain and also experience more intense acute exacerbations of pain periodically, which is called breakthrough pain (BTP). Patients may also endure acute pain from repetitive painful procedures during cancer treatment. Patients may have a combination of nociceptive and neuropathic pain. For example, a patient may have nociceptive pain as a result of tumor growth, and also report radiating sharp and shooting neuropathic pain if the tumor is pressing against a nerve plexus. Nociceptive Pain Nociception includes four specific processes: transduction, transmission, perception, and modulation Transduction o Refers to the processes by which noxious stimuli, such as a surgical incision or burn, activate primary afferent neurons called nociceptors, located throughout the body. o These neurons have the ability to respond selectively to noxious stimuli generated as a result of tissue damage from mechanical (e.g., incision, tumor growth), thermal (e.g., burn, frostbite), chemical (e.g., toxins, chemotherapy), and infectious sources. o Prostaglandins are lipid compounds that initiate inflammatory responses that increase tissue swelling and pain at the site of injury. o NSAIDs produce pain relief by mediating inflammation at the site of trauma, primarily by blocking the formation of prostaglandins. o Acetaminophen is known to be a COX inhibitor that has minimal peripheral effect, is not anti-inflammatory, and can both relieve pain and reduce fever by preventing the formation of prostaglandins in the CNS Stepanie Bryn O. Agustero BSN 3A 8|P a g e N o v. 2 0 , 2 0 2 3 Republic of the Philippines Province of Zamboanga del Sur J.H. CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City o o Transmission o Effective transduction generates an action potential that is transmitted along the lightly myelinated rapid conducting A-delta fibers and the unmyelinated slower impulse conducting C fibers. o The endings of A-delta fibers detect thermal and mechanical injury, allow relatively quick localization of pain, and are responsible for a rapid reflex withdrawal from the painful stimulus. o Unmyelinated C fibers respond to mechanical, thermal, and chemical stimuli. They produce poorly localized and often aching or burning pain. o A-beta (β) fibers are the largest of the fibers and respond to touch, movement, and vibration but do not normally transmit pain o The primary A-delta fibers release glutamate. Glutamate is a key neurotransmitter because it binds to the N-methyl-Daspartate (NMDA) receptor and promotes pain transmission. Perception o Perception is the result of the neural activity associated with transmission of noxious stimuli o It requires activation of higher brain structures for the occurrence of awareness, emotions, and impulses associated with pain/ Modulation o Modulation of the information generated in response to noxious stimuli occurs at every level from the periphery to the cortex and involves many different neurochemicals o For example, serotonin and norepinephrine are inhibitory neurotransmitters that are released in the spinal cord and the brain stem by the descending (efferent) fibers of the modulatory system. o Some antidepressants provide pain relief by blocking the body’s reuptake (resorption) of serotonin and norepinephrine, extending their availability to fight pain Additional Info Nociception o Is the physiological process by which the body detects and responds to noxious or harmful stimuli, commonly known as pain. The nociceptive process involves four main stages: o Transduction: Transduction is the conversion of noxious stimuli into electrical signals. Specialized receptors called nociceptors detect potentially damaging stimuli such as heat, pressure, or chemicals. When activated, nociceptors convert these stimuli into electrical signals, creating action potentials. o Transmission: Transmission involves the relay of the pain signals from the site of injury or stimulation to the spinal cord and then to the brain. After transduction, the electrical signals (action potentials) travel along nerve fibers, known as A- o delta and C fibers, towards the spinal cord. At the spinal cord, these signals are transmitted to neurons that carry them to the brain, specifically to areas associated with pain perception. Perception: Perception is the conscious awareness and interpretation of the pain signals. In this stage, the brain processes and interprets the incoming signals, giving rise to the conscious experience of pain. The perception of pain is influenced by various factors, including emotions, past experiences, and individual pain thresholds. Modulation: Modulation involves the modification or control of pain signals, either enhancing or inhibiting them. Inhibitory and facilitatory pathways in the nervous system can modulate the intensity of pain signals. This modulation can occur at various levels, including the spinal cord and higher brain centers. Endogenous substances like endorphins, which are natural painkillers, play a role in modulating the perception of pain. These four processes work together to enable the body to detect, transmit, interpret, and regulate the experience of pain in response to harmful stimuli, contributing to the overall protective function of pain in maintaining body integrity. Neuropathic Pain Neuropathic pain is caused by either a lesion or a disease involving the somatosensory nervous system Although specific causes may vary based on the underlying pathology, it is theorized that there are changes in the ion channels; imbalance of the stimuli processing between excitatory and inhibitory somatosensory signals; activity of glial cells; or potential differences in modulation of pain that occur with neuropathic pain Peripheral Mechanisms o Nerve endings in the periphery can become damaged, leading to abnormal reorganization in the nervous system called maladaptive neuroplasticity o Changes in ion channels can occur, such as increased sodium channel activity in sensory nerves resulting in heightened excitability, increased transduction, and release of neurotransmitters. These and many other processes lead to a phenomenon called peripheral sensitization o Allodynia, or pain from a normally non-noxious stimulus (e.g., touch), is one such type of abnormal sensation and a common feature of neuropathic pain o Hyperalgesia is an increased response of pain sensation from a stimulus which at a usual pain threshold produces a less intense pain response. Central Mechanisms o Central sensitization is defined as abnormal hyperexcitability of central 686 neurons in the spinal cord, which results from complex changes induced by incoming afferent barrages of nociceptors, which also can result in allodynia and hyperalgesia Additional Info Neuropathic pain is a type of pain that arises from a dysfunction or damage to the nervous system, particularly the peripheral or central nervous system. Unlike nociceptive pain, which results from actual or potential tissue damage, neuropathic pain is often characterized by abnormal signaling within the nervous system. It can be chronic and may persist long after the initial injury or damage has healed. Neuropathic pain can manifest in various ways, such as burning, tingling, electric shock-like sensations, and hypersensitivity to touch. The processes involved in neuropathic pain include: o Peripheral Nerve Damage: Neuropathic pain often begins with damage to the peripheral nerves, which are responsible for transmitting signals between the body and the spinal cord. This damage can result from conditions like diabetes, infections, traumatic injuries, or autoimmune disorders. Stepanie Bryn O. Agustero BSN 3A 9|P a g e N o v. 2 0 , 2 0 2 3 Republic of the Philippines Province of Zamboanga del Sur J.H. CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City o Aberrant Signal Processing: In neuropathic pain, there is a disruption in the normal processing of pain signals. Nerve fibers may become hyperexcitable, and the transmission of signals can become distorted, leading to spontaneous and exaggerated pain sensations even in the absence of an actual noxious stimulus. o Central Sensitization: Neuropathic pain can also involve central sensitization, where the central nervous system, including the spinal cord and brain, becomes hypersensitive to pain signals. This heightened sensitivity can amplify the perception of pain and contribute to the chronic nature of neuropathic pain. o Altered Modulation: The modulation of pain signals is disrupted in neuropathic pain. Inhibitory pathways that normally dampen pain signals may be impaired, while excitatory pathways may be enhanced. This imbalance contributes to the persistent and often intense nature of neuropathic pain. o Neuroplastic Changes: Chronic neuropathic pain can lead to structural and functional changes in the nervous system, a phenomenon known as neuroplasticity. These changes can perpetuate the pain experience, making it more resistant to treatment and contributing to the long-term nature of neuropathic pain. Common examples of conditions associated with neuropathic pain include diabetic neuropathy, post-herpetic neuralgia (resulting from shingles), nerve compression syndromes, and certain types of traumatic nerve injuries. Treatment of neuropathic pain often involves a multidisciplinary approach, combining medications, physical therapy, and sometimes surgical interventions to address the underlying causes and manage symptoms. Pain Assessment The highly subjective nature of pain causes challenges in assessment and management; however, the patient’s self-report is the undisputed standard for assessing the existence and intensity of pain The following are components of a comprehensive pain assessment: o Location(s) of pain: Ask the patient to state or point to the area(s) of pain on the body. o Intensity: Ask the patient to rate the severity of the pain using a reliable and valid pain assessment tool. o Numeric Rating Scale (NRS): The NRS is most often presented as a horizontal 0- to 10-point scale, with word anchors of “no pain” at one end of the scale, “moderate pain” in the middle of the scale, and “worst possible pain” at the end of the scale. o Wong–Baker FACES Pain Rating Scale: The FACES scale consists of six cartoon faces with word descriptors, ranging from a smiling face on the left for “no pain (or hurt)” to a frowning, tearful face on the right for “worst pain (or hurt).” o Faces Pain Scale—Revised (FPS-R): The FPS-R has six faces to make it consistent with other scales using the 0 to 10 metric. The faces range from a neutral facial expression to one of intense pain and are numbered 0, 2, 4, 6, 8, and 10. o Verbal descriptor scale (VDS): A VDS uses different words or phrases to describe the intensity of pain, such as “no pain, mild pain, moderate pain, severe pain, very severe pain, and worst possible pain.” o Visual Analogue Scale (VAS): The VAS is a horizontal (sometimes vertical) 10-cm line with word anchors at the extremes, such as “no pain” on one end and “pain as bad as it could be” or “worst possible pain” on the other end. (Impractical and rarely used) o Quality: Ask the patient to describe how the pain feels. Descriptors such as “sharp,” “shooting,” or “burning” o Onset and duration: Ask the patient when the pain started and whether it is constant or intermittent. o Aggravating and relieving factors: Ask the patient what makes the pain worse and what makes it better. o Effect of pain on function and quality of life: The effect of pain on the ability to perform recovery activities should be regularly evaluated in the patient with acute pain. o Comfort–function goal (pain intensity): For patients with acute pain, identify short-term functional goals and reinforce to the patient that good pain control will more likely lead to successful achievement of the goals. o Other information: The patient’s culture, past pain experiences, and pertinent medical history such as comorbidities, laboratory tests, and diagnostic studies are considered when establishing a treatment plan Patients who are unable to report their pain are at higher risk for undertreated pain than those who can report The Hierarchy of Pain Measures is recommended as a framework for assessing pain in patients who are nonverbal. The key components of the hierarchy require the nurse to (1) attempt to obtain self-report, (2) consider underlying pathology or conditions and procedures that might be painful (e.g., surgery), (3) observe behaviors, (4) evaluate physiologic indicators, and (5) conduct an analgesic trial. o FLACC: indicated for use in young children. Scores are assigned after assessing Facial expression, Leg movement, Activity, Crying, and Consolability, with each of these five categories assigned scores from 0 to 2, yielding a total composite score of 0 to 10. o PAINAD (Pain Assessment IN Advanced Dementia): indicated for use in adults with advanced dementia who are not able to verbalize their needs. o CPOT (Critical Care Pain Observation Tool): indicated for use in patients in critical-care units who cannot self-report pain, whether or not they may be intubated Following initiation of the pain management plan, pain is reassessed and documented on a regular basis to evaluate the effectiveness of treatment. At a minimum, pain should be reassessed with each new report of pain and before and after the administration of analgesic agents The frequency of reassessment depends on the stability of the patient and the timing of peak effect of the medication administered, which is generally between 15 and 30 minutes following parenteral administration and following oral administration Pain Management Optimal pain relief is the responsibility of every member of the health care team and begins with titration of the analgesic agent, followed by continued prompt assessment, analgesic agent administration, and nonpharmacologic interventions during the course of care to safely achieve pain intensities that allow patients to meet their functional goals with relative ease. Pharmacologic Management of Pain: Multimodal Analgesia A multimodal regimen intentionally and simultaneously combines medications with different underlying mechanisms, along with nonpharmacologic interventions, which allows for lower doses of each of the medications in the treatment plan, reducing the potential for adverse effects Routes of Administration o Oral is the preferred route of analgesic administration and should be used whenever feasible. Generally best tolerated, easiest to administer, and most cost-effective. o When the oral route is not possible, such as when patients cannot swallow, are NPO (nothing by mouth), or nauseated, other routes of administration are used. o Patients with cancer pain who are unable to swallow may take analgesic agents by the transdermal, rectal, or subcutaneous route of administration o In the immediate postoperative period, the IV route is most often the first-line route of administration for analgesic delivery, and patients are transitioned to the oral route as tolerated o The rectal route of analgesic administration is an alternative route when oral or IV analgesic agents are not an option (e.g., for palliative purposes during end-of-life care). Diarrhea, perianal abscess or fistula, and abdominoperineal resection are also relative contraindications. o The topical route of administration is used for both acute and chronic pain. o A more invasive method used to manage pain is accomplished using neuraxial analgesia, which involves Stepanie Bryn O.

CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City o o administering medication in the epidural or subarachnoid space Intrathecal catheters for acute pain management are used most often for providing anesthesia or a single bolus dose of an analgesic agent. A pain management technique that involves the use of an indwelling catheter is the continuous peripheral nerve block (also called perineural anesthesia), whereby an initial local anesthetic block is established and followed by the placement of a catheter or catheters through which an infusion of local anesthetic, usually ropivacaine or bupivacaine, is infused continuously to the targeted site of innervation. Dosing Regimen Around-The-Clock (ATC) dosing regimens are designed to control pain for patients who report pain being present 12 hours or more during a 24-hour period; when pain is continuous. PRN dosing of analgesic agents is appropriate for intermittent pain, such as prior to painful procedures and for BTP Patient-Controlled Analgesia Patient-controlled analgesia (PCA) is an interactive method of pain management that allows patients to treat their pain by selfadministering doses of analgesic agents A PCA infusion device is programmed so that the patient can press a button (pendant) to self-administer a dose of an analgesic agent (PCA dose) at a set time interval (demand or lockout) as needed. The primary benefit of PCA is that it recognizes that only the patient can feel the pain and only the patient knows how much analgesic will relieve it. Authorized Agent Controlled Analgesia – candidates for PCA but unable to use the PCA equipment, the nurse or a capable family member may be authorized to manage the patient’s pain using PCA equipment Analgesic Medications Analgesic Medications Nonopioid Opioid Category Examples Antipasmodic Agents acetaminophen and NSAIDs Antipasmodic Agents morphine, hydromorphone, fentanyl, and oxycodone Co-analgesic Agents local anesthetics, some anticonvulsants, and some antidepressants postoperative pain. IV formulations of ketorolac and ibuprofen are available for acute pain treatment. o Adverse Effects: Acetaminophen is widely considered one of the safest, best tolerated, and most cost effective of the analgesic agents; A principle of nonopioid analgesic use is to administer the lowest dose for the shortest time necessary (NSAID) Acetaminophen Hepatotoxicity (liver damage) as a result of overdose. Acetaminophen interactions that warrant caution: Alcohol (serious liver damage), and Warfarin (toxicity w/ bleeding) NSAIDS gastric toxicity and ulceration (most common) carry a risk of CV adverse effects can negatively impact renal function Most nonselective NSAIDs increase bleeding time Opioid Analgesic Agents o Divided into two major groups: (1) mu agonist opioids comprise the larger of the two groups and include morphine, hydromorphone, hydrocodone, fentanyl, oxycodone, and methadone, among others. (2) agonist– antagonist opioids include buprenorphine, nalbuphine, and butorphanol o There are three major classes of opioid receptor sites involved in analgesia: the mu, delta, and kappa o The opioid analgesic agents that are designated as first line (e.g., morphine, hydromorphone, fentanyl, and oxycodone) belong to the mu opioid agonist o They bind as agonists, producing analgesia, at the kappa opioid receptor sites, and as weak antagonists at the mu opioid receptor sites. o Antagonists (e.g., naloxone, naltrexone, naloxegol) are medications that also bind to opioid receptors but produce no analgesia; reverse adverse effects, such as respiratory depression o Administration: The goal of titration is to use the smallest dose that provides satisfactory pain relief with the fewest adverse effects Patients with cancer pain most often are titrated upward over time for progressive pain Patients with acute pain, particularly postoperative pain, are eventually titrated downward and discontinued as pain resolves o Equianalgesia Nonopioid Analgesic Agents o Indications: mild to some moderate nociceptive pain (e.g., from surgery, trauma, or osteoarthritis); added to opioids, local anesthetics, and/or anticonvulsants as part of a multimodal analgesic regimen for more severe nociceptive pain; surgical patients should routinely be given acetaminophen and an NSAID in scheduled doses throughout the postoperative course o Administration: Nonopioids are often combined in a single tablet with opioids, such as oxycodone or hydrocodone; Acetaminophen is versatile in that it can be given by multiple routes of administration, including oral (has a long history of safety in recommended doses in all age groups), rectal, and IV (approved for the treatment of pain and fever and is given by a 15minute infusion in single or repeated dose); A benefit of the NSAID group is the availability of a wide variety of agents for administration via noninvasive routes. Ibuprofen, naproxen, and celecoxib are the most widely used oral NSAIDs; If rectal formulations are unavailable, an intact oral tablet or a crushed tablet in a gelatin capsule may be inserted into the rectum. The rectal route may require higher doses than the oral route to achieve similar analgesic effects; Diclofenac can be prescribed in patch and gel form for topical administration, and an intranasal patient-controlled formulation of ketorolac has been approved for the treatment of Stepanie Bryn O.

CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City Substance Use Disorder, Physical Dependence, and Tolerance o Physical Dependence – a normal response that occurs with repeated administration of the opioid; It is manifested by the occurrence of withdrawal symptoms when c the opioid is suddenly stopped or rapidly reduced, or an antagonist such as naloxone is given; Withdrawal symptoms may be suppressed by the natural, gradual reduction of the opioid as pain decreases or by gradual, systematic reduction, referred to as tapering o Tolerance – also a normal physiologic response that can occur with regular administration of an opioid and consists of a decrease in one or more effects of the opioid o Substance Use Disorder (SUD) – historically known as addiction or addictive disease, and defined as a chronic, relapsing, treatable neurologic disease; the impaired use of a substance even while experiencing major problems, characterized by impaired control over use, compulsive use, continued use despite harm, and craving for the substance o Withdrawal – occurs when a medication or substance to which the body has become dependent is abruptly reduced or discontinued; Withdrawal is exhibited by a cascade of unpleasant symptoms including anxiety, nausea, vomiting, rhinitis, sneezing, chills, hot flashes, abdominal cramping, tremors, diaphoresis, hyperreflexia, diarrhea, piloerection, and/or insomnia o Pseudoaddiction – a mistaken diagnosis of substance use disorder that occurs when a patient’s pain is not well controlled; the patient may begin to manifest symptoms suggestive of SUD Select Opioid Analgesic Agents o Morphine The standard against which all other opioid medications are compared A hydrophilic medication (readily absorbed in aqueous solution), which accounts for its slow onset and long duration of action It has two principal, clinically significant metabolites: morphine-3-glucuronide (M3G) and morphine-6glucuronide (M6G). o Fentanyl A lipophilic (readily absorbed in fatty tissues) opioid and as such has a fast onset and short duration of action Most commonly used IV opioid when rapid analgesia is desired; no clinically relevant metabolites; produces minimal hemodynamic adverse effects o Hydromorphone Less hydrophilic than morphine but less lipophilic than fentanyl, which contributes to an onset and duration of action that is intermediate between morphine and fentanyl This medication is often used as an alternative to morphine, especially for acute pain because the two medications produce similar analgesia and have comparable adverse effect profiles. o Oxycodone Available in the United States for administration by the oral route only and is used to treat all types of pain. Single-entity short-acting and modified-release oxycodone formulations are used most often for moderate to severe cancer pain and in some patients with moderate to severe noncancer pain o Oxymorphone Has been available for many years in parenteral formulation and more recently in short-acting and modified-release oral tablets for the treatment of moderate to severe chronic pain It must be taken on an empty stomach (1 hour before or 2 hours after a meal), and coingestion of alcohol at the time of dosing must be avoided because food and alcohol can increase the serum concentration of the medication up to 300% o Hydrocodone Commercially available only in combination with nonopioids (e.g., with acetaminophen or ibuprofen), which limits its use to the treatment of mild to some moderate pain o Methadone A unique synthetic opioid analgesic medication that may have advantages over other opioids in carefully selected patients No active metabolites, methadone has a very long and highly variable half-life Dual-Mechanism Analgesic Agents o The dual-mechanism analgesic agents tramadol and tapentadol bind weakly to the mu opioid receptor site and block the reuptake (resorption) of the inhibitory neurotransmitters serotonin and norepinephrine at central synapses in the spinal cord and brain stem of the modulatory descending pain pathway o Tramadol Used for both acute and chronic pain and is available in oral short-acting and modified-release formulations, including a short-acting tablet in combination with acetaminophen o Tapentadol Available in short-acting and modified-release oral formulations. This medication has been shown to produce dose-dependent analgesia comparable to oxycodone o Opioids to Avoid Codeine Meperidine o Adverse Effects of Opioid Analgesic Agents Constipation, nausea, vomiting, pruritus, hypotension, and sedation (most common) Respiratory depression, while less common, is the most serious and feared of the opioid adverse effects Postoperative ileus; opioid-induced androgen deficiency and sleep disordered breathing; Prophylactic treatment (e.g., dexamethasone and a serotonin receptor antagonist, such as ondansetron, at the end of surgery) Excessive sedation can progress to clinically significant respiratory depression Opioid-induced respiratory depression is dose related and preceded by increasing sedation. Prevention of clinically significant opioid-induced respiratory depression begins with the administration of the lowest effective opioid dose, careful titration, close monitoring of sedation and respiratory function and status (i.e., rate, depth, regularity, excursion) throughout therapy, and prompt dose reduction when advancing sedation is detected Co-Analgesic Medications o Local Anesthetics Local anesthetics have a long history of safe and effective use for all types of pain management. sodium channel blockers The Lidocaine patch 5% is placed directly over or adjacent to the painful area for absorption into the tissues directly below (12 hours on, 12 hours off regimen). Bupivacaine, which can be instilled in a surgical wound, have longer duration of action CNS signs of systemic toxicity include ringing in the ears, metallic taste, irritability, and seizures. Signs of cardiotoxicity include circumoral tingling and numbness, bradycardia, cardiac arrhythmias, and CV collapse o Membrane Stabilizer Anticonvulsant Medications The anticonvulsant calcium channel blockers Gabapentin and Pregabalin are first-line analgesic agents for neuropathic pain Initial doses of Gabapentin may not provide analgesia; titration to effective dosing may take up to 2 months. Pregabalin has a more rapid onset of action with expected maximum effect typically reached in 2 weeks. initiated with low doses and titrated according to patient response Primary adverse effects of anticonvulsants are sedation and dizziness o Antidepressant Medications Stepanie Bryn O.

CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City 2 major groups: the tricyclic antidepressants (TCAs) and the serotonin and norepinephrine reuptake inhibitors (SNRIs). The TCAs desipramine and nortriptyline and the SNRIs duloxetine and venlafaxine as first-line options for neuropathic pain treatment Their delayed onset of action makes them inappropriate for acute pain treatment Initiated with low doses and titrated according to patient response Primary adverse effects of TCAs are dry mouth, sedation, dizziness, mental clouding, weight gain, and constipation. Orthostatic hypotension is a potentially serious TCA adverse effect. The most serious adverse effect is cardiotoxicity, and patients with significant heart disease are at high risk. SNRIs are thought to have a more favorable adverse effect profile and to be better tolerated than the TCAs. Due to the side effects, including delirium and confusion, amitriptyline is not indicated for use in older adults The most common SNRI adverse effects are nausea, headache, sedation, insomnia, weight gain, impaired memory, sweating, and tremors o Ketamine an NMDA antagonist, it blocks the binding of glutamate at the NMDA receptors and thus prevents the transmission of pain to the brain via the ascending pathway At high doses, this medication can produce psychomimetic effects (e.g., hallucinations, dreamlike feelings) does not produce respiratory depression given most often by the IV route but can also be given by the oral, rectal, intranasal, and subcutaneous routes used as a third-line analgesic agent for refractory acute pain Use of Placebos o A placebo is “any sham medication or procedure designed to be void of any known therapeutic value” o When a person responds to a placebo in accordance with its intent, it is called a positive placebo response Nonpharmacologic Methods of Pain Management Nonpharmacologic therapies are usually effective alone for mild to some moderate-intensity pain. They should not be a replacement or alternative but complement pharmacologic therapies as part of a multimodal approach for more severe pain. The effectiveness of nonpharmacologic methods can be unpredictable, and although not all will relieve pain, they offer many benefits to patients with pain. Many patients find that the use of nonpharmacologic methods helps them cope better with their pain and feel greater control over the pain experience Lecture Notes Pain is the 5th vital sign. Acute pain is the most severe. Radiating pain is the pain that comes from an internal organ that radiates to another area. The primary nursing responsibility for pts experiencing acute pain is assessing the anxiety level and provide analgesics or opioids (CNS depressants). The primary nursing responsibility for pts experiencing chronic pain is addressing the psychosocial aspect and evaluating the functioning of their ADLs. For cancer-related pain, nursing responsibilities focus on the risk for infection, buccal cavity sores and cuts, and leukocytopenia. Pain scale: 1-3 is mild; 4-7 is moderate; 8- 10 is severe. For mild pain, administer non-narcotics and modify environmental aspects. For moderate pain, provide weak and/or non-narcotics (opioids). For severe pain, use strong narcotics (opioids). Factors affecting pain response: o Past experiences o Anxiety and depression o Culture o Gerontological considerations (as one grew older, senses decrease) o Gender (females have higher pain tolerance) o Genetics o Placebo effect Characteristics of pain level: o Intensity o Location o Quality The “PQRSTU,” “OLDCARTES,” or “COLDSPA” mnemonics are helpful in remembering a standardized set of questions used to gather additional data about a patient’s pain o PQRSTU Provocation/Palliation – What makes your pain worse? What makes your pain feel better? Quality – What does the pain feel like? Note: You can provide suggestions for pain characteristics such as “aching,” “stabbing,” or “burning.” Region – Where exactly do you feel the pain? Does it move around or radiate elsewhere? Note: Instruct the patient to point to the pain location. Severity – How would you rate your pain on a scale of 0 to 10, with “0” being no pain and “10” being the worst pain you’ve ever experienced? Timing/Treatment – When did the pain start? What were you doing when the pain started? Is the pain constant or does it come and go? If the pain is intermittent, when does it occur? How long does the pain last? Have you taken anything to help relieve the pain? Understanding – What do you think is causing the pain? o OLDCARTES Onset: When did the pain start? How long does it last? Location: Where is the pain? Duration: How long has the pain has been going on? How long does an episode last? Characteristics: What does the pain feel like? Can the pain be described in terms such as stabbing, gnawing, sharp, dull, aching, piercing, or crushing? Aggravating Factors: What brings the pain? What makes the pain worse? Are there triggers such as movement, body position, activity, eating, or the environment? Radiating: Does the pain travel to another area or the body, or does it stay in one place? Treatment: What has been done to make the pain better and has it been helpful? Examples include medication, position change, rest, and application of hot or cold. Effect: What is the effect of the pain on participating in your daily life activities? Severity: Rate your pain from 0 to 10 o COLDSPA Stepanie Bryn O.

CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City Chronic Obstructive Pulmonary Disease A preventable and treatable slowly progressive respiratory disease of airflow obstruction involving the airways, pulmonary parenchyma, or both The airflow limitation or obstruction in COPD is not fully reversible. COPD may include diseases that cause airflow obstruction (e.g., emphysema, chronic bronchitis) or any combination of these disorders. While COPD and lower respiratory diseases are the fourth leading cause of death for people of all ages in the United States, they are the third leading cause of death for people ages 65 and over C: Character O: Onset L: Location D: Duration S: Severity P: Pattern A: Associated Factors 4: Management of Patients with Chronic Pulmonary Disease Glossary Air Trapping – incomplete emptying of alveoli during expiration due to loss of lung tissue elasticity (emphysema), bronchospasm (asthma), or airway obstruction Alpha1 -Antitrypsin Deficiency – genetic disorder resulting from deficiency of alpha1 -antitrypsin, a protective agent for the lung; increases patient’s risk for developing panacinar emphysema even in the absence of smoking Asthma – a heterogeneous disease, usually characterized by chronic airway inflammation; defined by history of symptoms such as wheeze, shortness of breath, chest tightness, and cough that vary over time and in intensity Bronchiectasis – chronic, irreversible dilation of the bronchi and bronchioles that results from the destruction of muscles and elastic connective tissue; dilated airways become saccular and are a medium for chronic infection Chest Percussion – manually cupping hands over the chest wall and using vibration to mobilize secretions by mechanically dislodging viscous or adherent secretions in the lungs Chest Physiotherapy (CPT) – therapy used to remove bronchial secretions, improve ventilation, and increase the efficiency of the respiratory muscles; types include postural drainage, chest percussion, and vibration, and breathing retraining Chronic Bronchitis – a disease of the airways defined as the presence of cough and sputum production for at least a combined total of 3 months in each of 2 consecutive years Chronic Obstructive Pulmonary Disease (COPD) – disease state characterized by airflow limitation that is not fully reversible; sometimes referred to as chronic airway obstruction or chronic obstructive lung disease Desaturate – a precipitous drop in the saturation of hemoglobin with oxygen Dry-Powder Inhaler (DPI) – a compact, portable inspiratory flow– driven inhaler that delivers dry-powder medications into the patient’s lungs Emphysema – a disease of the airways characterized by destruction of the walls of overdistended alveoli Flutter Valve – portable handheld mucous clearance device; consisting of a tube with an oscillating steel ball inside; upon expiration, high-frequency oscillations facilitate mucous expectoration Fraction of Inspired Oxygen (FiO2 ) – concentration of oxygen delivered (e.g., 1.0 equals to 100% oxygen) Hypoxemia – decrease in arterial oxygen tension in the blood Hypoxia – decrease in oxygen supply to the tissues and cells Polycythemia – increase in the red blood cell concentration in the blood; in COPD, the body attempts to improve oxygencarrying capacity by producing increasing amounts of red blood cells Postural Drainage – positioning the patient to allow drainage from all lobes of the lungs and airways Pressurized Metered-Dose Inhaler (pMDI) – a compact, portable patient-activated pressurized medication canister that provides aerosolized medication that the patient inhales into the lungs Small-Volume Nebulizer (SVN) – a handheld generator-driven medication delivery system that provides aerosolized liquid medication that the patient inhales into the lungs Spirometry – pulmonary function tests that measure specific lung volumes (e.g., FEV1 , FVC) and rates (e.g., FEF25%–75%); may be measured before and after bronchodilator administration Vibration – a type of massage given by quickly tapping the chest with the fingertips or alternating the fingers in a rhythmic manner, or by using a mechanical device to assist in mobilizing lung secretions Pathophysiology In COPD, the airflow limitation is both progressive and associated with the lungs’ abnormal inflammatory response to noxious particles or gases. 1. The inflammatory response occurs throughout the proximal and peripheral airways, lung parenchyma, and pulmonary vasculature 2. Because of the chronic inflammation and the body’s attempts to repair it, changes and narrowing occur in the airways. a. In the proximal airways (trachea and bronchi greater than 2 mm in diameter), changes include increased numbers of goblet cells and enlarged submucosal glands, both of which lead to hypersecretion of mucus. b. In the peripheral airways (bronchioles less than 2 mm diameter), inflammation causes thickening of the airway wall, peribronchial fibrosis, exudate in the airway, and overall airway narrowing (obstructive bronchiolitis). 3. Over time, this ongoing injury-and-repair process causes scar tissue formation and narrowing of the airway lumen 4. Inflammatory and structural changes also occur in the lung parenchyma (respiratory bronchioles and alveoli). 5. Alveolar wall destruction leads to loss of alveolar attachments and a decrease in elastic recoil. 6. Finally, the chronic inflammatory process affects the pulmonary vasculature and causes thickening of the lining of the vessel and hypertrophy of smooth muscle, which may lead to pulmonary hypertension Chronic Bronchitis – defined as the presence of cough and sputum production for at least 3 months in each of 2 consecutive years. 1. In many cases, smoke or other environmental pollutants irritate the airways, resulting in inflammation and hypersecretion of mucus. Constant irritation causes the mucus-secreting glands and goblet cells to increase in number, leading to increased mucus production. 2. Mucus plugging of the airway reduces ciliary function. Bronchial walls also become thickened, further narrowing the bronchial lumen (Fig. 20-1). 3. Alveoli adjacent to the bronchioles may become damaged and fibrosed, resulting in altered function of the alveolar macrophages. This is significant because the macrophages play an important role in destroying foreign particles, including bacteria. 4. As a result, the patient becomes more susceptible to respiratory infection. A wide range of viral, bacterial, and mycoplasma infections can produce acute episodes of bronchitis. 5. Exacerbations of chronic bronchitis are most likely to occur during the winter when viral and bacterial infections are more prevalent Stepanie Bryn O.

CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City Emphysema – a pathologic term that describes an abnormal distention of the airspaces beyond the terminal bronchioles and destruction of the walls of the alveoli 1. In emphysema, impaired oxygen and carbon dioxide exchange results from destruction of the walls of overdistended alveoli. In addition, a chronic inflammatory response may induce disruption of the parenchymal tissues. This end-stage process progresses slowly for many years. 2. As the walls of the alveoli are destroyed (a process accelerated by recurrent infections), the alveolar surface area in direct contact with the pulmonary capillaries continually decreases. 3. This causes an increase in dead space (lung area where no gas exchange can occur) and impaired oxygen diffusion, which leads to hypoxemia. 4. In the later stages of disease, carbon dioxide elimination is impaired, resulting in hypercapnia (increased carbon dioxide tension in arterial blood) leading to respiratory acidosis. 5. As the alveolar walls continue to break down, the pulmonary capillary bed is reduced in size. Consequently, resistance to pulmonary blood flow is increased, forcing the right ventricle to maintain a higher blood pressure in the pulmonary artery. Hypoxemia may further increase pulmonary artery pressures (pulmonary hypertension). 6. Cor pulmonale, one of the complications of emphysema, is right-sided heart failure brought on by long-term high blood pressure in the pulmonary arteries. This high pressure in the pulmonary arteries and right ventricle lead to back up of blood in the venous system, resulting in dependent edema, distended neck veins, or pain in the region of the liver. o 2 Types: In the panlobular (panacinar) there is destruction of the respiratory bronchiole, alveolar duct, and alveolus. All airspaces within the lobule are essentially enlarged, but there is little inflammatory disease. A hyperinflated (hyperexpanded) chest, marked dyspnea on exertion, and weight loss typically occur. To move air into and out of the lungs, negative pressure is required during inspiration, and an adequate level of positive pressure must be attained and maintained during expiration. Instead of being an involuntary passive act, expiration becomes active and requires muscular effort. In the centrilobular (centroacinar) Pathologic changes take place mainly in the center of the secondary lobule, preserving the peripheral portions of the acinus (i.e., the terminal airway unit where gas exchange occurs). Frequently, there is a derangement of ventilation–perfusion ratios, producing chronic hypoxemia, hypercapnia, polycythemia (i.e., an increase in red blood cells), and episodes of right-sided heart failure. This leads to central cyanosis and respiratory failure. The patient also develops peripheral edema. Risk Factors The most important environmental risk factor for COPD worldwide is cigarette smoking. Smoking depresses the activity of scavenger cells and affects the respiratory tract’s ciliary cleansing mechanism, which keeps breathing passages free of inhaled irritants, bacteria, and other foreign matter. Exposure to tobacco smoke accounts for an estimated 80–90% of cases of chronic obstructive pulmonary disease Second-hand smoke Increased age Occupational exposure—dust, chemicals Indoor and outdoor air pollution Genetic abnormalities, including a deficiency of alpha1 antitrypsin, an enzyme inhibitor that normally counteracts the destruction of lung tissue by certain other enzymes Clinical Manifestations COPD is generally a progressive disease characterized by three primary symptoms: chronic cough, sputum production, and dyspnea. Weight loss is common, because dyspnea interferes with eating and the work of breathing is energy depleting In patients with COPD who have a primary emphysematous component, chronic hyperinflation leads to the “barrel chest” thorax configuration. This configuration results from a more fixed position of the ribs in the inspiratory position (due to hyperinflation) and from loss of lung elasticity. Retraction of the supraclavicular fossae occurs on inspiration, causing the shoulders to heave upward. In advanced emphysema, the abdominal muscles may also contract on inspiration. There are systemic or extrapulmonary manifestations of COPD. These include musculoskeletal wasting, metabolic disturbances, and depression (a frequent comorbidity that accompanies chronic debilitating illnesses). Research has indicated that depression, metabolic syndrome, and diabetes are frequent comorbidities of COPD Assessment and Diagnostic Findings Spirometry is used to evaluate airflow obstruction, which is determined by the ratio of FEV1 to forced vital capacity (FVC). With obstruction, the patient either has difficulty exhaling or cannot forcibly exhale air from the lungs, reducing the FEV1. Spirometry is also used to determine reversibility of obstruction after the use of bronchodilators Arterial blood gas measurements may also be obtained to assess baseline oxygenation and gas exchange and are especially important in advanced COPD. A chest x-ray may be obtained to exclude alternative diagnoses. A computed tomography (CT) chest scan is not routinely obtained in the diagnosis of COPD, but a high-resolution CT scan may help in the differential diagnosis. Screening for alpha1 -antitrypsin deficiency is suggested for all adults who are symptomatic, especially for patients younger than 45 years Factors that determine the clinical course and survival of patients with COPD include history of cigarette smoking, exposure to secondhand smoke, age, rate of decline of FEV1 , hypoxemia, pulmonary artery pressure, resting heart rate, weight loss, reversibility of airflow obstruction, and comorbidities. In diagnosing COPD, several differential diagnoses must be ruled out. The primary differential diagnosis is asthma. Key factors in determining the diagnosis are the patient’s history, severity of symptoms, and responsiveness to bronchodilators. Complications Respiratory insufficiency and failure are major life-threatening complications of COPD. Respiratory insufficiency and failure may be chronic (with severe COPD) or acute (with severe bronchospasm or pneumonia in a patient with severe COPD) Other complications of COPD include pneumonia, chronic Stepanie Bryn O.

CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City atelectasis, pneumothorax, and pulmonary arterial hypertension (cor pulmonale). Medical Management Therapeutic strategies for the patient with COPD include promoting smoking cessation as appropriate, providing supplemental oxygen therapy as indicated, prescribing medications, and managing exacerbations Some patients may benefit from surgical interventions; whereas others with advanced COPD may benefit from palliative care Risk Reduction o The major risk factor associated with COPD is environmental exposure and it is modifiable. The most important environmental exposure is smoking o Smoking cessation is the single most cost-effective intervention to reduce the risk of developing COPD and to stop its progression o Nicotine replacement—a first-line pharmacotherapy that reliably increases long-term smoking abstinence rates— comes in a variety of forms (gum, inhaler, nasal spray, transdermal patch, sublingual tablet, or lozenge). Bupropion SR and nortriptyline, both antidepressants, may also increase long-term quit rates. Other pharmacologic agents include the antihypertensive agent clonidine; however, its side effects limit its use. Varenicline, a nicotinic acetylcholine receptor partial agonist, may assist in smoking cessation Oxygen Therapy – is the administration of oxygen at a concentration greater than that found in the environmental atmosphere. o Oxygen transport to tissues depends on factors such as cardiac output, arterial oxygen content, concentration of hemoglobin, and metabolic requirements o Indications A change in the patient’s respiratory rate or pattern may be one of the earliest indicators of the need for oxygen therapy. These changes may result from hypoxemia or hypoxia. o Complications Oxygen is a medication, and except in emergency situations it is given only when prescribed by a health care provider. In general, a patient with any type of respiratory disorder is given oxygen therapy only to increase the partial pressure of arterial oxygen (PaO2 ) back to the patient’s normal baseline, which may vary from 60 to 95 mm Hg Increased amounts of oxygen may produce toxic effects on the lungs and central nervous system or may depress ventilation, which is a particularly lethal adverse effect in patients with COPD Oxygen toxicity may occur when too high concentration of oxygen is given for an extended period (generally longer than 24 hours) Absorption Atelectasis – Oxygen replaces Nitrogen, the alveoli collapse, causing atelectasis Because oxygen supports combustion, there is always a danger of fire when it is used. It is important to post “No Smoking” signs when oxygen is in use. Oxygen therapy equipment is also a potential source of bacterial contamination o Oxygen Administration A nasal cannula is used when the patient requires a low to medium concentration of oxygen for which precise accuracy is not essential A reservoir cannula stores oxygen in a thin membrane during exhalation. When the patient’s inspiration exceeds the flow rate into the cannula, the patient receives additional gas from the reservoir membrane The nasal (oropharyngeal) catheter delivers low to moderate concentrations of oxygen and is rarely used. This method of delivering low-flow oxygen is usually reserved for use in special procedures, such as those that examine the patient’s airways and lungs (bronchoscopy). Simple masks, low-flow design, are used to administer low to moderate concentrations of oxygen. Partial rebreathing masks have a reservoir bag that must remain inflated during both inspiration and expiration. Nonrebreathing masks are similar in design to partial rebreathing masks except that they have additional valves. Venturi mask is the most reliable and accurate method for delivering precise concentrations of oxygen through noninvasive means. Transtracheal oxygen catheter requires minor surgery to insert a catheter through a small incision directly into the trachea. It is indicated for patients with chronic oxygen therapy needs. Other oxygen devices include aerosol masks, tracheostomy collars, T-pieces, and face tents, all of which are used with aerosol devices (nebulizers) that can be adjusted for oxygen concentrations from 28% to 100% (0.28 to 1.00). Quality and Safety Nursing Alert o Oxygen therapy is variable in patients with COPD; its aim in COPD is to achieve an acceptable oxygen level without a fall in the pH (increasing hypercapnia) Pharmacologic Therapy o Medication regimens used to manage COPD are based on disease severity. For grade I (mild) COPD, a short-acting bronchodilator may be prescribed. For grade II or III (moderate or severe) COPD, a shortacting bronchodilator and regular treatment with one or more long-acting bronchodilators may be used. For grade III or IV (severe or very severe) COPD, medication therapy includes regular treatment with long-acting bronchodilators and/or inhaled corticosteroids (ICSs) for repeated exacerbations. o Other pharmacologic treatments that may be used in COPD include alpha1 - antitrypsin augmentation therapy, antibiotic agents, mucolytic agents, antitussive agents, vasodilators, and opioids. o Vaccines are also effective in that they prevent exacerbations by thwarting respiratory infections. For instance, influenza vaccines can reduce serious illness and death in patients with COPD; Pneumococcal vaccination also reduces the incidence of community-acquired pneumonia in the general older adult population Management of Exacerbations o An exacerbation of COPD is defined as an event in the natural course of the disease characterized by acute changes (worsening) in the patient’s respiratory symptoms beyond the normal day-to-day variations. o Roflumilast may be used as a treatment to reduce the risk of exacerbations in patients with severe COPD associated with chronic bronchitis and a history of exacerbations o When the patient with an exacerbation of COPD arrives in an ED, the first line of treatment is supplemental oxygen therapy and rapid assessment to determine if the exacerbation is life-threatening o A short-acting inhaled bronchodilator may be used to assess response to treatment. Oral or intravenous (IV) corticosteroids, in addition to bronchodilators, are recommended in the hospital management of a COPD exacerbation. o The administration of antibiotics remains controversial, but in general, they should be administered when the patient has three cardinal symptoms of an exacerbation: increase in dyspnea, increase in sputum volume, and sputum purulence Surgical Management o A bullectomy is a surgical option for select patients with bullous emphysema o Lung Volume Reduction Surgery is a treatment option for patients with advanced or end-stage COPD (grade IV) with a primary emphysematous component are limited; it is a palliative surgical option. o Lung transplantation is a viable option for definitive surgical treatment of severe COPD in select patients. It has Stepanie Bryn O. Agustero BSN 3A 16 | P a g e N o v. 2 0 , 2 0 2 3 Republic of the Philippines Province of Zamboanga del Sur J.H. CERILLES STATE COLLEGE West Capitol Road, Balangasan District, Pagadian City been shown to improve quality of life and functional capacity in some patients with COPD Pulmonary Rehabilitation o Pulmonary rehabilitation, one of the most cost-effective treatment strategies, is a holistic intervention aimed at improving physical and psychological health of patients with COPD o The primary goals of rehabilitation are to reduce symptoms, improve quality of life, and increase physical and emotional participation in everyday activities Nutritional Therapy o Nutritional assessment and counseling are important for patients with COPD. Nutritional status is reflected in severity of symptoms, degree of disability, and prognosis. Significant weight loss is often a major problem; however, excessive weight can also be problematic, although it occurs less often. Most patients with COPD have difficulty gaining and maintaining weight. Palliative Care o Palliative care is integral for the patient with advanced COPD. Unfortunately, palliative care is often not considered until the disease is far advanced. The overall goals of palliative care are to manage symptoms and improve the quality of life for patients and families with advanced disease Nursing Management Assessing the Patient o Assessment involves obtaining information about current symptoms as well as previous disease manifestations Achieving Airway Clearance o Bronchospasm reduces the caliber of the small bronchi and may cause dyspnea, static secretions, and infection. Increased mucus production, along with decreased mucociliary action, contributes to further reduction in the caliber of the bronchi and results in decreased airflow and decreased gas exchange. This is further aggravated by the loss of lung elasticity that occurs with COPD. These changes in the airway require that the nurse monitor the patient for dyspnea and hypoxemia o Diminishing the quantity and viscosity of sputum can clear the airway and improve pulmonary ventilation and gas exchange. All pulmonary irritants should be eliminated or reduced, particularly cigarette smoke, which is the most persistent source of pulmonary irritation. o Postural Drainage (Segmented Bronchial Drainage) Postural drainage allows the force of gravity to assist in the removal of bronchial secretions. The secretions drain from the affected bronchioles into the bronchi and trachea and are removed by coughing or suctioning. o Chest Percussion and Vibration Thick secretions that are difficult to cough up may be loosened by percussing (tapping) and vibrating the chest or through the use of an HFCWO vest. Chest percussion and vibration help dislodge mucus adhering to the bronchioles and bronchi. Chest percussion is carried out by cupping the hands and lightly striking the chest wall in a rhythmic fashion over the lung segment to be drained Vibration is the technique of applying manual compression and tremor to the chest wall during the exhalation phase of respiration Improving Breathing Patterns o The breathing pattern of most people with COPD is shallow, rapid, and inefficient; the more severe the disease, the more inefficient the breathing pattern. o Impaired breathing patterns and shortness of breath are due to the modified respiratory mechanics of the chest wall and lung resulting from air trapping (i.e., incomplete emptying of alveoli during expiration), ineffective diaphragmatic movement, airway obstruction, the metabolic cost of breathing, and stress. o Breathing retraining may help improve breathing patterns. Training in diaphragmatic breathing reduces the respiratory rate, increases alveolar ventilation, and sometimes helps expel as much air as possible during expiration. o Pursed-lip breathing helps slow expiration, prevent collapse of small airways, and control the rate and depth of respiration. It also promotes relaxation, which allows patients to gain control of dyspnea and reduce feelings of panic. Promoting Self-Care o As gas exchange, airway clearance, and the breathing pattern improve, the patient is encouraged to assume increasing participation in self-care activities; coordinate diaphragmatic breathing with activities; self-regulation of fluid intake Improving Activity Tolerance o People with COPD have decreased exercise tolerance during specific periods of the day, especially in the morning on arising, because bronchial secretions have collected in the lungs during the night while the patient was lying down o Physical conditioning techniques include breathing exercises and general exercises intended to conserve energy and increase pulmonary ventilation Encouraging Effective Coping Monitoring and Managing Potential Complications o The nurse must assess for various complications of COPD, such as life threatening respiratory insufficiency and failure, as well as respiratory infection and chronic atelectasis o The nurse monitors for cognitive changes (personality and behavioral changes, memory impairment), increasing dyspnea, tachypnea, and tachycardia, which may indicate increasing hypoxemia and impending respiratory failure. o The nurse monitors pulse oximetry values to assess the patient’s need for oxygen and administers supplemental oxygen as prescribed. o The nurse also instructs the patient about signs and symptoms of respiratory infection that may worsen hypoxemia and reports changes in the patient’s physical and cognitive status to the primary provider. o To prevent pneumonia, the nurse encourages the patient with COPD to be immunized against influenza and pneumococcal pneumonia o The nurse must assess the patient’s actual and potential triggers that cause bronchospasm so that avoidance or a treatment plan can be established. Lecture Notes COPD o Emphysema (pink puffers, because of increased retention of CO2) o o Chronic bronchitis (blue bloaters, inflammation of the bronchi due to irritants when the immune system traps them, releasing mucus) Our respiratory drive is inhaling oxygen and exhaling carbon dioxide. In a hemoglobin, the heme carries the O2 while the globin carries the CO2. For dry cough, provide antitussives (Robitussin). For productive cough (with mucus), provide mucolytics (Solmux). Both decreased oxygen (hypoxia) and increased carbon dioxide (respiratory acidosis) will eventually lead to death. Nursing management: o Avoid the patient from irritants o Give O2 at 1-3 LPM o Positioning: orthopneic The compensation mechanism is to produce more RBCs resulting to increased RBCs leading to polycythemia vera. Blood pressure will increase to pump the viscous blood components. Factors of COPD: o Smoking – alveoli recoil is diminished thus, retaining more CO2 o Air pollutants o Aging – reduced elasticity, alveoli are overdistended resulting to poor gas exchange that will lead to hypoxia Asthma is reversible. Status Asthmaticus – prolonged asthma that will not react to conventional therapy. Corticosteroids are given. Steroids given overly will damage the kidneys and liver resulting to edema. Its clinical manifestation is respiratory failure Stepanie Bryn O. Agustero BSN 3A 17 | P a g e N o v. 2 0 , 2 0 2 3 Republic of the Philippines Province of Zamboanga del Sur J.H.
