NUR 312 1st sem | AY 2023-2024 Topic: TEXTBOOK OF MED-SURG NURSING (UNIT 4) Author: BRUNNER AND SUDDARTH’S PREOPERATIVE NURSING MANAGEMENT Perioperative Nursing Many patients enter the hospital 90 minutes prior to surgery and have necessary medical assessments and analyses preceding the surgical intervention. The surgery is followed by a limited recovery period in the postanesthesia care unit (PACU). Traumatic and emergency surgery most often results in prolonged hospital stays. Patients who are acutely ill or undergoing major surgery and patients with concurrent medical disorders may require supportive supplementary care from other medical disciplines, which can be coordinated more easily within the hospital setting. The high acuity level of surgical inpatients and the greater complexity of procedures have placed greater demands on the practice of nursing in this setting. Phases of Perioperative Nursing Care 1. Preoperative Phase- begins when the decision to proceed with surgical intervention is made and ends with the transfer of the patient onto the operating room (OR) bed 2. Intraoperative Phase- begins when the patient is transferred onto the OR bed and ends with admission to the PACU. • Intraoperative Nursing Responsibilities involves acting as scrub nurse, circulating nurse, or registered nurse first assistant. 3. Postoperative Phase- begins with the admission of the patient to the PACU and ends with a follow-up evaluation in the clinical setting or home Domains of conceptual model of patient care (AORN) • Safety • Physiologic Response • Behavioral responses • Health care systems • Note: o The first three domains reflect phenomena of concern to perioperative nurses and are composed of nursing diagnoses, interventions, and outcomes. o The fourth domain—the health care system— consists of structural data elements and focuses on clinical processes and outcomes. Surgical Classifications (Surgery may be perform for several reason) a. Diagnostic- Surgery done to verify certain diagnosis. Example is Breast Biopsy and Exploratory Laparotomy o Exploratory Laparotomy- Surgery done to estimate the disease and maybe done to confirm a diagnosis. b. Curative- Remove or repair damage, disease, or congenitally malformed organs or tissues. Example is Excision of Tumor and Inflamed appendix. c. Reparative- repairs congenitally defective organs, thus improving its function and appearance. Example is multiple wound repair d. Ablative Surgery- Involves removing deceased organs e. Reconstructive or Cosmetic- Example is mammoplasty or a facelift. f. Palliative- Done to relieve symptoms but does not cure the disease g. Restorative- To restore the functioning of the damage organs/tissues Categories of Surgery Based on Urgency a. Emergent- Patient required immediate attention, order maybe life-threatening and should be without delay. Examples are Severe Bleeding, Fractured skull, gunshot, stab wound, extensive burn, internal obstruction b. Urgent- Patient requires prompt attention and must be done in 24-30 hrs. Example is Acute bladder infection, kidney or urethral stone. c. Required- Patient needs to have surgery and surgery is plan within few weeks or months. Example is Prostatic Hyperplasia without bladder obstruction, Thyroid disorder, and Cataracts d. Elective- Patient should have the surgery and failure to have surgery is not catastrophic. It includes repair of scars, simple hernia, vaginal repair. e. Optional- Decision rests with the patient and is considered to be a personal preference. Example would be cosmetic surgery. Gerontologic Considerations Because the older patient may have greater perioperative risks, the following factors are critical: 1. skillful preoperative assessment and treatment 2. proficient anesthesia and surgical care 3. meticulous and competent postoperative and postanesthesia management Bariatric Patients • Bariatrics is a specialty that revolves around diagnosing, treating, and managing patients who are obese. • Obesity is defined as a body mass index of greater than 30 kg/m2 • Wound infections are more common in patients that are obese • The patient with obesity tends to have shallow respirations when supine, increasing the risk of hypoventilation and postoperative pulmonary complications. Patients with Disabilities • Special considerations for patients with mental or physical disabilities include the need for appropriate assistive devices, modifications in preoperative education, and additional assistance with and attention to positioning or transferring. • People who are hearing impaired may need and are entitled by law to a sign interpreter or some alternative communication system perioperatively. • These needs must be identified in the preoperative evaluation and clearly communicated to personnel. Patients Undergoing Ambulatory Surgery • Ambulatory surgery includes outpatient, same-day, or short-stay surgery not requiring admission for an overnight hospital stay but may entail observation in a hospital setting for 23 hours or less. • The nurse needs to be sure that the patient and family understand that the patient will first go to the preoperative holding area before going to the OR for the surgical procedure and then will spend some time in the PACU before being discharged home with the family member later that day.

BSN 3-1 (THIRD YEAR) NUR 312 1st sem | AY 2023-2024 Topic: TEXTBOOK OF MED-SURG NURSING (UNIT 4) Author: BRUNNER AND SUDDARTH’S Patients Undergoing Emergency Surgery • Emergency surgeries are unplanned and occur with little time for preparation of the patient or the perioperative team. • Factors that affect patients preparing to undergo surgery also apply to patients undergoing emergency surgery, although usually in a very condensed time frame. • A quick visual survey of the patient is essential to identify all sites of injury if the emergency surgery is due to trauma Informed Consent • is the patient’s autonomous decision about whether to undergo a surgical procedure. • Voluntary and written informed consent from the patient is necessary before nonemergent surgery can be performed to protect the patient from unsanctioned surgery and protect the surgeon from claims of an unauthorized operation or battery. • The nurse may ask the patient to sign the consent form and witness the signature • it is the surgeon’s responsibility to provide a clear and simple explanation of what the surgery will entail prior to the patient giving consent. o The surgeon must also inform the patient of the benefits, alternatives, possible risks, complications, disfigurement, disability, and removal of body parts as well as what to expect in the early and late postoperative periods. • The nurse ascertains that the consent form has been signed before administering psychoactive premedication • The patient personally signs the consent if of legal age and mentally capable. o Permission is otherwise obtained from a surrogate, who most often is a responsible family member (preferably next of kin) or legal guardian. Many ethical principles are integral to informed consent. Informed consent is necessary in the following circumstances: • Invasive procedures, such as a surgical incision, a biopsy, a cystoscopy, or paracentesis • Procedures requiring sedation and/or anesthesia (see Chapter 18 for a discussion of anesthesia) • A nonsurgical procedure, such as an arteriography, that carries more than a slight risk to the patient • Procedures involving radiation • Blood product administration Valid Informed Consent • Valid consent must be freely given, without coercion. Patient must be at least 18 years of age • a physician must obtain consent, and a professional staff member must witness patient’s signature. Preoperative Assessment • The goal in the preoperative period is for the patient to be as healthy as possible. • A plan of action is designed so that potential complications are averted. • Latex, the milky fluid from the rubber tree, is found in many everyday products, and repeated exposure may • cause some people to develop the allergy as an immune response to the protein Health care providers also should be alert for signs of abuse, which can occur at any age, in either sex, and in any socioeconomic, ethnic, and cultural group. Nutritional and Fluid Status • Optimal nutrition is an essential factor in promoting healing and resisting infection and other surgical complications. • Nutritional needs may be determined by measurement of body mass index and waist circumference. • Any nutritional deficiency should be corrected before surgery to provide adequate protein for tissue repair. • The depletion of fluids and electrolytes following bowel preparation, especially when combined with prolonged fasting, can result in dehydration and chemical imbalances, even among healthy surgical patients. Dentition • The condition of the mouth is an important health factor to assess. • Dental caries, dentures, and partial plates are particularly significant to the anesthesiologist or CRNA, because decayed teeth or dental prostheses may become dislodged during intubation and occlude the airway • The condition of the mouth is also important because any bodily infection, even in the mouth, can be a source of postoperative infection. Drug or Alcohol Use • Ingesting even moderate amounts of alcohol prior to surgery can weaken a patient’s immune system and increase the likelihood of developing postoperative complications • If emergency surgery is required, local, spinal, or regional block anesthesia is used for minor surgery • The person with a history of alcohol abuse often suffers from malnutrition and other systemic problems or metabolic imbalances that increase surgical risk. Psychosocial Factors • The nurse anticipates that most patients have emotional reactions prior to surgery—obvious or veiled, normal or abnormal. • Fear may be related to the unknown, lack of control, or of death and may be influenced by anesthesia, pain, complications, cancer, or prior surgical experience. • People express fear in different ways. Important outcomes • The value and reliability of available support systems are assessed. • Assessing the patient’s readiness to learn and determining the best approach to maximize comprehension • Usual level of functioning Spiritual and Cultural Beliefs • Spiritual beliefs play an important role in how people cope with fear and anxiety. • Regardless of the patient’s religious affiliation, adhering to spiritual beliefs can be therapeutic PADUA, JAKE DONELY P. BSN 3-1 (THIRD YEAR) NUR 312 1st sem | AY 2023-2024 • • • • • Topic: TEXTBOOK OF MED-SURG NURSING (UNIT 4) Author: BRUNNER AND SUDDARTH’S Asking whether the patient’s spiritual advisor knows about the impending surgery is a caring, nonthreatening approach. Showing respect for a patient’s cultural values and beliefs facilitates rapport and trust. Certain ethnic groups are unaccustomed to expressing feelings openly with strangers and nurses need to consider this pattern of communication when assessing pain. In some cultural groups, it is seen as impolite to make direct eye contact with others and doing so is seen as disrespectful. Perhaps the most valuable skill at the nurse’s disposal is listening carefully to the patient and observing body language, especially when obtaining the history. Preoperative Teaching 1. Deep Breathing, Coughing, and Incentive Spirometry educate the patient how to promote optimal lung expansion and resulting blood oxygenation after anesthesia. The patient assumes a sitting position to enhance lung expansion. The nurse then demonstrates how to take a deep, slow breath and how to exhale slowly. After practicing deep breathing several times, the patient is instructed to breathe deeply, exhale through the mouth, take a short breath, and cough deeply in the lungs Splinting or placing the hands across the incision site acts as an effective support when coughing. The goal in promoting coughing is to mobilize secretions so that they can be removed. 2. Mobility and Active Body Movement The goals of promoting mobility postoperatively are to improve circulation, prevent venous stasis, and promote optimal respiratory function. The nurse explains the rationale for frequent position changes after surgery and then shows the patient how to turn from side to side and how to assume the lateral position without causing pain or disrupting intravenous (IV) lines, drainage tubes, or other equipment. Exercise of the extremities includes extension and flexion of the knee and hip joints (similar to bicycle riding while lying on the side) unless contraindicated by type of surgical procedure (e.g., hip replacement). The nurse should remember to use proper body mechanics and to instruct the patient to do the same. 3. Pain Management A pain assessment should include differentiation between acute and chronic pain. A pain intensity scale should be introduced and explained to the patient to promote more effective postoperative pain management. patient is prepared to differentiate acute postoperative pain from a chronic condition such as back pain. Postoperatively, medications are given to relieve pain and maintain comfort without suppressing respiratory function Preoperative Instructions to Prevent Postoperative Complications 4. o Diaphragmatic Breathing o Coughing o Leg Exercises o Turning to the Side o Getting Out of Bed Cognitive Coping Strategies Cognitive strategies may be useful for relieving tension, overcoming anxiety, decreasing fear, and achieving relaxation o Imagery: The patient concentrates on a pleasant experience or restful scene. o Distraction: The patient thinks of an enjoyable story or recites a favorite poem or song. o Optimistic self-recitation: The patient recites optimistic thoughts (“I know all will go well ”). o Music: The patient listens to soothing music (an easy-to-administer, inexpensive, noninvasive intervention). Providing Psychosocial Interventions 1. Reducing Anxiety and Decreasing Fear Nurses must introduce themselves, giving their title and a brief synopsis of their professional role and background. The nurse assists the patient to identify coping strategies that he or she has previously used to decrease fear Discussions with the patient to help determine the source of fears can help with expression of concerns. Knowing ahead of time about the possible need for a ventilator, drainage tubes, or other types of equipment helps decrease anxiety related to the postoperative period. 2. Respecting Cultural, Spiritual, and Religious Beliefs Psychosocial interventions include identifying and showing respect for cultural, spiritual, and religious beliefs These responses should be recognized as normal for those patients and families and should be respected by perioperative personnel. If patients decline blood transfusions for religious reasons (Jehovah’s Witnesses), this information needs to be clearly identified in the preoperative period, documented, and communicated to the appropriate personnel. 3. Maintaining Patient Safety Protecting patients from injury is one of the major roles of the perioperative nurse. These apply to hospitals as well as to ambulatory surgery centers and office-based surgery facilities Managing Nutrition and Fluids The purpose of withholding food and fluid before surgery is to prevent aspiration. Until recently, fluid and food were restricted preoperatively overnight and often longer. Specific recommendations depend on the age of the patient and the type of food eaten. Preparing the Bowel 4. 5. PADUA, JAKE DONELY P. BSN 3-1 (THIRD YEAR) NUR 312 1st sem | AY 2023-2024 Topic: TEXTBOOK OF MED-SURG NURSING (UNIT 4) Author: BRUNNER AND SUDDARTH’S - 6. Enemas are not commonly prescribed preoperatively unless the patient is undergoing abdominal or pelvic surgery. The goals of this preparation are to allow satisfactory visualization of the surgical site and to prevent trauma to the intestine or contamination of the peritoneum by fecal material. Unless the condition of the patient presents some contraindication, the toilet or bedside commode, rather than the bedpan, is used for evacuating the enema if the patient is hospitalized during this time. Preparing the Skin The goal of preoperative skin preparation is to decrease bacteria without injuring the skin. If the surgery is not performed as an emergency, most health care facilities and ambulatory surgical centers have implemented antiseptic skin cleansing protocols. Generally, hair is not removed preoperatively unless the hair at or around the incision site is likely to interfere with the operation. To ensure the correct site, the surgical site is typically marked by the patient and the surgeon prior to the procedure. Immediate Preoperative Nursing Interventions 1. Administering Preanesthetic Medication The use of preanesthetic medication is minimal with ambulatory or outpatient surgery If prescribed, it is usually given in the preoperative holding area. During this time, the nurse observes the patient for any untoward reaction to the medications. In these situations, the preoperative medication is prescribed “on call to OR.” It usually takes 15 to 20 minutes to prepare the patient for the OR. 2. Maintaining the Preoperative Record Preoperative checklists contain critical elements that must be checked and verified preoperatively The nurse completes the preoperative checklist (see Fig. 17-2). The completed medical record (with the preoperative checklist and verification form) accompanies the patient to the OR with the surgical consent form attached, along with all laboratory reports and nurses’ records. 3. Transporting the Patient to the Presurgical Area The patient is brought to the holding area or presurgical suite about 30 to 60 minutes before the anesthetic is to be given. The patient is taken to the preoperative holding area, greeted by name, and positioned comfortably on the stretcher or bed. Patient safety in the preoperative area is a priority.

INTRAOPERATIVE NURSING MANAGEMENT The intraoperative experience has undergone many changes and advances that make it safer and less disturbing to patients. Even with these advances, anesthesia and surgery still place the patient at risk for several complications or adverse events. Consciousness or full awareness, mobility, protective biologic functions, and personal control are totally or partially relinquished by the patient when entering the operating room (OR). Staff from the departments of anesthesia, nursing, and surgery work collaboratively to implement professional standards of care, to control iatrogenic and individual risks, to prevent complications, and to promote high-quality patient outcomes. Surgical Team • The surgical team consists of the: o patient, o the anesthesiologist (physician) or certified registered nurse anesthetist (CRNA), o the surgeon, o nurses, o surgical technicians, and o registered nurse first assistants (RFNAs) or certified surgical technologists (assistants). • The anesthesiologist or CRNA administers the anesthetic agent (substance used to induce anesthesia) and monitors the patient’s physical status throughout the surgery. • The surgeon, nurses, technicians, and assistants scrub and perform the surgery. • The person in the scrub role, either a nurse or a surgical technician, provides sterile instruments and supplies to the surgeon during the procedure by anticipating the surgical needs as the surgical case progresses. • The circulating nurse coordinates the care of the patient in the OR. A. Patient • These feelings depend to a large extent on the amount and timing of preoperative sedation, preoperative education, and the individual patient. • Fears about loss of control, the unknown, pain, death, changes in body structure, appearance, or function, and disruption of lifestyle all contribute to anxiety. • The patient is subject to several risks. • Infection, failure of the surgery to relieve symptoms or correct a deformity, temporary or permanent complications related to the procedure or the anesthetic agent, and death are uncommon but potential outcomes of the surgical experience B. Circulating Nurse • The circulating nurse (or circulator), a qualified registered nurse, works in collaboration with surgeons, anesthesia providers, and other health care providers to plan the best course of action for each patient • In this leadership role, the circulating nurse manages the OR and protects the patient’s safety and health by monitoring the activities of the surgical team, checking the OR conditions, and continually assessing the patient for signs of injury and implementing appropriate interventions • The team is coordinated by the circulating nurse, who ensures cleanliness, proper temperature, humidity, PADUA, JAKE DONELY P.

The circulating nurse monitors aseptic practices to avoid breaks in technique while coordinating the movement of related personnel (medical, x-ray, and laboratory), as well as implementing fire safety precautions (Seifert, Peterson, & Graham, 2015). In addition, the circulating nurse is responsible for ensuring that the second verification of the surgical procedure and site takes place and is documented Scrub Role The registered nurse, licensed practical nurse, or surgical technologist (or assistant) performs the activities of the scrub role, including performing hand hygiene; setting up the sterile equipment, tables and sterile field; preparing sutures, ligatures, and special equipment and assisting the surgeon and the surgical assistants during the procedure by anticipating the instruments and supplies that will be required, such as sponges, drains, and other equipment. scrub person and the circulating nurse count all needles, sponges, and instruments to be sure that they are accounted for and not retained as a foreign body in the patient Tissue specimens obtained during surgery are labeled by the person in the scrub role and sent to the laboratory by the circulating nurse. Surgeon The surgeon performs the surgical procedure, heads the surgical team, and is a licensed physician (MD or DO), oral surgeon (DDS or DMD), or podiatrist (DPM) who is specially trained and qualified. The Registered Nurse First Assistant The registered nurse first assistant (RNFA) is another member of the OR team. RNFA responsibilities may include handling tissue, providing exposure at the operative field, suturing, and maintaining hemostasis The RNFA must be aware of the objectives of the surgery, must have the knowledge and ability to anticipate needs and to work as a skilled member of a team, and must be able to handle any emergency situation in the OR. The Anesthesiologist and CRNA An anesthesiologist is a physician specifically trained in the art and science of anesthesiology. A CRNA is a qualified and specifically trained health care professional who administers anesthetic agents, has graduated from an accredited nurse anesthesia master’ s program, and has passed examinations sponsored by the American Association of Nurse Anesthetists. The anesthesiologist or CRNA assesses the patient before surgery, selects the anesthesia, administers it, intubates the patient if necessary, manages any technical problems related to the administration of the anesthetic agent, and supervises the patient’s condition throughout the surgical procedure. Before the patient enters the OR, often at preadmission testing, the anesthesiologist or CRNA visits the patient to perform an assessment, supply information, and answer questions. When the patient arrives in the OR, the anesthesiologist or CRNA reassesses the patient’s physical condition immediately prior to initiating anesthesia. • The anesthetic agent is given, and the patient’s airway is maintained through an intranasal intubation (if the surgeon is using an oral approach to surgery), intubation with an endotracheal tube (ETT), or a laryngeal mask airway (LMA). The Surgical Environment • The surgical environment is known for its stark appearance and cool temperature. • The surgical suite is behind double doors, and access is limited to authorized, appropriately clad personnel. • Precautions include adherence to principles of surgical asepsis; strict control of the OR environment is required, including use of laminar airflow rooms as indicated for the surgical procedure, and decreasing noise as well as the number of operating theater door openings • the cleanliness of the rooms; the sterility of equipment and surfaces; processes for scrubbing, gowning, and gloving; and OR attire • Warming the patient, which may begin in the preoperative phase of surgery, is continued or initiated during the perioperative stage • To provide the best possible conditions for surgery, the OR is situated in a location that is central to all supporting services • To help decrease microbes, the surgical area is divided into three zones: o the unrestricted zone, where street clothes are allowed; the o semirestricted zone, where attire consists of scrub clothes and caps; and o the restricted zone, where scrub clothes, shoe covers, caps, and masks are worn. • The surgeons and other surgical team members wear additional sterile clothing and protective devices during surgery. • Masks are worn at all times in the restricted zone of the OR. o Masks should fit tightly; should cover the nose and mouth completely; and should not interfere with breathing, speech, or vision. o Masks must be adjusted to prevent venting from the sides. Disposable masks have a filtration efficiency exceeding 95%. o Masks are changed between patients and should not be worn outside the surgical department. • Headgear should completely cover the hair (head and neckline, including beard) so that hair, bobby pins, clips, and particles of dandruff or dust do not fall on the sterile field. Principles of Surgical Asepsis • Surgical asepsis prevents the contamination of surgical wounds. • All surgical supplies, instruments, needles, sutures, dressings, gloves, covers, and solutions that may come in contact with the surgical wound or exposed tissues must be sterilized before use • Traditionally, the surgeon, surgical assistants, and nurses prepared themselves by scrubbing their hands and arms with antiseptic soap and water • Surgical team members wear long-sleeved, sterile gowns and gloves. PADUA, JAKE DONELY P. BSN 3-1 (THIRD YEAR) NUR 312 1st sem | AY 2023-2024 • • • Topic: TEXTBOOK OF MED-SURG NURSING (UNIT 4) Author: BRUNNER AND SUDDARTH’S Head and hair are covered with a cap, and a mask is worn over the nose and mouth to minimize the possibility that bacteria from the upper respiratory tract will enter the wound. During surgery, only personnel who have scrubbed, gloved, and gowned touch sterilized objects. An area of the patient’s skin larger than that requiring exposure during the surgery is meticulously cleansed, and an antiseptic solution is applied Basic Guidelines for Maintaining Surgical Asepsis • All materials in contact with the surgical wound or used within the sterile field must be sterile. Sterile surfaces or articles may touch other sterile surfaces or articles and remain sterile; contact with unsterile objects at any point renders a sterile area contaminated. • Gowns of the surgical team are considered sterile in front from the chest to the level of the sterile field. The sleeves are also considered sterile from 2 in above the elbow to the stockinette cuff. • Sterile drapes are used to create a sterile field (see Fig. 18-2). Only the top surface of a draped table is considered sterile. During draping of a table or patient, the sterile drape is held well above the surface to be covered and is positioned from front to back. • Items are dispensed to a sterile field by methods that preserve the sterility of the items and the integrity of the sterile field. After a sterile package is opened, the edges are considered unsterile. Sterile supplies, including solutions, are delivered to a sterile field or handed to a scrubbed person in such a way that the sterility of the object or fluid remains intact. • The movements of the surgical team are from sterile to sterile areas and from unsterile to unsterile areas. Scrubbed people and sterile items contact only sterile areas; circulating nurses and unsterile items contact only unsterile areas. • Movement around a sterile field must not cause contamination of the field. Sterile areas must be kept in view during movement around the area. At least a 1-ft distance from the sterile field must be maintained to prevent inadvertent contamination. • Whenever a sterile barrier is breached, the area must be considered contaminated. A tear or puncture of the drape permitting access to an unsterile surface underneath renders the area unsterile. Such a drape must be replaced. • Every sterile field is constantly monitored and maintained. Items of doubtful sterility are considered unsterile. Sterile fields are prepared as close as possible to the time of use. • The routine administration of hyperoxia (high levels of oxygen) is not recommended to reduce surgical site infections. The Surgical Experience a. General Anesthesia Anesthesia is a state of narcosis (severe central nervous system depression produced by pharmacologic agents), analgesia, relaxation, and reflex loss. Patients under general anesthesia are not arousable, not even to painful stimuli. - - - - General anesthesia consists of four stages, each associated with specific clinical manifestations: o Stage I: beginning anesthesia. Dizziness and a feeling of detachment may be experienced during induction. The patient may have a ringing, roaring, or buzzing in the ears and, although still conscious, may sense an inability to move the extremities easily. These sensations can result in agitation. During this stage, noises are exaggerated; even low voices or minor sounds seem loud and unreal. For these reasons, unnecessary noises and motions are avoided when anesthesia begins. o Stage II: excitement. The excitement stage, characterized variously by struggling, shouting, talking, singing, laughing, or crying, is often avoided if IV anesthetic agents are given smoothly and quickly. The pupils dilate, but they constrict if exposed to light; the pulse rate is rapid, and respirations may be irregular. o Stage III: surgical anesthesia. Surgical anesthesia is reached by administration of anesthetic vapor or gas and supported by IV agents as necessary. The patient is unconscious and lies quietly on the table. The pupils are small but constrict when exposed to light. With proper administration of the anesthetic agent, this stage may be maintained for hours in one of several planes, ranging from light (1) to deep (4), depending on the depth of anesthesia needed. o Stage IV: medullary depression. This stage is reached if too much anesthesia has been given. Respirations become shallow, the pulse is weak and thready, and the pupils become widely dilated and no longer constrict when exposed to light. When opioid agents (narcotics) and neuromuscular blockers (relaxants) are given, several of the stages are absent. During smooth administration of an anesthetic agent, there is no sharp division between stages. The responses of the pupils, the blood pressure, and the respiratory and cardiac rates are among the most reliable guides to the patient’s condition. Anesthetic medications produce anesthesia because they are delivered to the brain at a high partial pressure that enables them to cross the blood–brain barrier. Inhalation • Inhaled anesthetic agents include volatile liquid agents and gases. • Gas anesthetic agents are given by inhalation and are always combined with oxygen. Nitrous oxide is the most commonly used gas anesthetic agent. • When inhaled, the anesthetic agents enter the blood through the pulmonary capillaries and act on cerebral centers to produce loss of consciousness and sensation. PADUA, JAKE DONELY P. BSN 3-1 (THIRD YEAR) NUR 312 1st sem | AY 2023-2024 Topic: TEXTBOOK OF MED-SURG NURSING (UNIT 4) Author: BRUNNER AND SUDDARTH’S Intravenous Administration • 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. • 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. • The IV anesthetic agents are nonexplosive, require little equipment, and are easy to administer. • IV anesthesia is useful for short procedures but is used less often for the longer procedures of abdominal surgery. It is not indicated for those who require intubation because of their susceptibility to respiratory obstruction. ✓ Regional Anesthesia ➢ It is a form of local anesthesia in which an anesthetic agent is injected around nerves so that the area supplied by these nerves is anesthetized. ➢ The effect depends on the type of nerve involved ➢ These are agents that will block the nerve impulse at its origin along afferent neurons and along the spinal cords. ➢ An anesthetic cannot be regarded as having worn off until all motor, sensory, and autonomic are no longer affected. ➢ Patient is awake ➢ Nurse must avoid careless conversation, unnecessary noise, and unpleasant odors. ➢ Provide a quiet environment ✓ Conduction Blocks and Spinal Anesthesia ➢ This may be subarachnoid block , epidural block, and spinal anesthesia ➢ Commonly used for CS, hysterectomy, appendectomy, or any abdominal surgery or amputation ➢ Injection of local anesthetic is into the spinal canal in the space surrounding the dura mater. ➢ Epidural Anesthetic will block sensory, motor, and autonomic functions. ➢ Advantage • Absence of headache ➢ Disadvantage • It is a challenge to introduce the anesthetic into the epidural rather than in the subarachnoid space. • If inadverted injection to the subarachnoid, instead of epidural mod, then the anesthetic agent will travel towards the head and high spinal anesthesia can result. This will produce a severe hypotension and respiratory depression and possible arrest. • Treatment of this complication o Airway support o IV fluid o Use of vasopressor ➢ ➢ ➢ ➢ ➢ ➢ ➢ ➢ Other type of nerve blocks include • Brachial plexus block which will produce anesthesia in the arms • Paravertebral anesthesia which produces anesthesia of the nerve supply in the chest, abdominal wall, and extremities • Transtracheal or caudal block which produces anesthesia of te perineum and occasionally on lower abdomen Spinal Anesthesia • It provides regions of anesthesia from the abdomen to the toes • It is a type of extensive conduction nerve block that is produced when a local anesthetic is introduced into the subarachnoid space and lumbar level. • Usually used is L4 and L5 • Spread of anesthetic agent and level of anesthesia will depend on the amount of the fluid injected. The speed with which it is injected, the positioning of the patient after the injection, and the specific gravity of the agent • Assist the anesthesiologist to position the patient in a knee chest position General agents used for conduction blocks and spinal anesthesia • Procaine • Tetracaine • Pontocaine • Lidocaine or Xylocaine • Bupivacaine After a few minutes after induction of spinal anesthetic, the anesthesia will have paralysis effect on toes, perineum, and gradually the legs and abdomen. If it reaches the upper thoracic and cervical spinal cord, it means high concentration and temporary partial or complete respiratory paralysis will be the result If respiratory muscles paralysis occurs, it is managed through mechanical ventilation until the effect of anesthetic on the respiratory nerves have worn off Nausea, vomiting and pain may occur during surgery when spinal anesthesia is used so as a rule this reaction will resolve from the manipulation of various structures particularly with those abdominal cavity Headache is the after effect of spinal anesthesia and there are several factors that are involve such as the size of the spinal needle used, the leakage of fluid from the subarachnoid space through the puncture site and the patient’s hydration status Measures that increases the Cerebrospinal pressure is very helpful in relieving headache such as keeping the patient lying lfat and PADUA, JAKE DONELY P.

Susceptible patients includes those with strong and bulky muscles, history of muscles cramps or muscle weakness or unexplained temperature elevation, and unexplained death of a family member during surgery that was accompanied by a febrile response. ✓ Brief Pathophysiology: ➢ During the anesthesia, the potent agent such as inhalation anesthetics and muscles relaxants may trigger the symptoms of malignant hyperthermia plus the stress and some medications such as sympathomimetic, theophylline, aminophylline, anti-cholinergic and cardiac glycosides can induce or intensify the reaction. ➢ It is related to muscle cell activity ➢ Calcium and essential factor in muscle contraction is normally stored in sacs in the sarcoplasm. So when nerve impulses stimulate the muscles, calcium is released allowing contraction to occur. Pumping mechanism returns calcium to the sacs so that the muscle can relax. ✓ This mechanism is disrupted. Calcuim ions are not returned and they accumulate causing clinical symptoms of hypermetabolism which in turn increases muscle contraction or rigidity, hyperthermia, and damage to CNS. ✓ Initial symptoms are related to cardiovascular and musculoskeletal activity ➢ Tachycardia – above 150 bpm; earliest sign ➢ Sympathetic nervous stimulation – leads to ventricular dysrhythmia, hypotension, decrease cardiac output, oliguria, and cardiac arrest ➢ With the abnormal transfer of calcium, rigidity or tetanus like movement may occur often in the jaw ➢ Rise in temperature – late sign that develops rapidly and the body temperature can increase 1 to 2 degrees Celsius every 5 mins.

In order for the patient to recover from anesthesia and the stress of the surgery. ● Final phase of the entire surgical process ● Most often the PACU or RR is located adjacently to the operating room ● Patients who have undergone surgery are placed in the PACU or RR, so that the highly skilled nurses can easily access if there is a complication with the anesthesia and can call immediately the anesthesiologist or anesthetist, surgeons and advanced hemodynamic and pulmonary monitoring and support ● There are special equipment and medication in the PACU ● The PACU is usually kept quiet, clean free of unnecessary equipment. This area is painted in soft, pleasing colors and has indirect lighting, it is also a sound proof ceiling and equipment that controls or eliminate noise such as plastic and basin, rubber bumpers on beds and tables are placed in the RR. ● It is isolated but visible quarters for disruptive patients ● The PACU should also be well-ventilated and these features will benefit the patient by helping to decrease anxiety and to promote comfort ● The PACU bed provides easy access to the patient, it is safe and easily movable, it can be readily placed in position to facilitate the use of measure to counter act shock and has the features that facilitate care such as IV poles, side rails, wheel breaks and a chart storage wrap. PHASES OF POSTANESTHESIA CARE ● Phase I PACU – it used during the immediate recovery phase, so intensive nursing care is provided ● Phase 2 PACU – is reserved for patients who requires less frequent observation and less nursing care. The patient is now prepared for discharge, so recliners rather than stretchers or beds are standard in many phase II units. Which also be referred as step down or sit up or progressive care unit. Patient may remain in phase II PACU unit for as long as 4 to 6 hours depending from the type of surgery and any pre-existing conditions of the patient ● Phase 3 PACU- the patient is prepared for discharge. ● In facilities without separate Phase I and Phase II unit, the patient will stay on the PACU and may be discharge home directly from the PACU ● Both Phase I and Phase II PACU nurses have special skills: ● Phase I PACU Nurse – will provide frequent care, every 15 minutes monitoring patient’s pulse, electrocardiogram, respiratory rate, blood pressure and pulse oximeter value (the blood oxygen level) and in some cases they check the end tidal carbon dioxide levels and the patient’s airway may become obstructed because of the latent effect of the recent anesthesia and the PACU nurse must be prepared in the air intubation and handling other emergencies that may occur ● Phase II PACU Nurse – must possess strong clinical assessment and patient teaching skills Admitting the Patient to the Postanesthesia Care Unit • Transferring the postoperative patient from the OR to the PACU is the responsibility of the anesthesiologist or certified registered nurse anesthetist (CRNA) and other licensed members of the OR team. • the anesthesia provider remains at the head of the stretcher (to maintain the airway), and a surgical team member remains at the opposite end. • The surgical incision is considered every time the postoperative patient is moved; many wounds are closed under considerable tension, and every effort is made to prevent further strain on the incision. • Orthostatic hypotension may occur when a patient is moved too quickly from one position to another • As soon as the patient is placed on the stretcher or bed, the soiled gown is removed and replaced with a dry gown. • The nurse who admits the patient to the PACU reviews essential information with the anesthesiologist or CRNA and the circulating nurse. • The nursing management objectives for the patient in the PACU are to provide care until the patient has recovered from the effects of anesthesia • Frequent, skilled assessments of the patient’s airway, respiratory function, cardiovascular function, skin color, level of consciousness, and ability to respond to commands are the cornerstones of nursing care in the PACU. • Vital signs are observed and recorded, as well as level of consciousness. The nurse performs and documents a baseline assessment, then checks the surgical site for drainage or hemorrhage and makes sure that all drainage tubes and monitoring lines are connected and functioning. • After the initial assessment, vital signs are monitored and the patient’s general physical status is assessed and documented at least every 15 minutes. Maintaining a Patent Airway • The primary objective in the immediate postoperative period is to maintain ventilation and thus prevent hypoxemia (reduced oxygen in the blood) and hypercapnia (excess carbon dioxide in the blood). o 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. • When the patient lies on their back, the lower jaw and the tongue fall backward and the air passages become obstructed (hypopharyngeal obstruction) • Signs of occlusion o choking; noisy and irregular respirations o decreased oxygen saturation scores; o within minutes, a blue, dusky color (cyanosis) of the skin • Because movement of the thorax and the diaphragm does not necessarily indicate that the patient is breathing, the nurse needs to place the palm of the hand at the patient’s nose and mouth to feel the exhaled breath. • The anesthesiologist or CRNA may leave a hard rubber or plastic airway in the patient’s mouth to maintain a patent airway • The nurse assists in initiating the use of the ventilator as well as the weaning and extubation processes • Some patients, particularly those who have had extensive or lengthy surgical procedures, may be transferred from the OR directly to the intensive care unit (ICU) or from the PACU to PADUA, JAKE DONELY P.

If the teeth are clenched, the mouth may be opened manually but cautiously with a padded tongue depressor. The head of the bed is elevated 15 to 30 degrees unless contraindicated, and the patient is closely monitored to maintain the airway as well as to minimize the risk of aspiration. Mucus or vomitus obstructing the pharynx or the trachea is suctioned with a pharyngeal suction tip or a nasal catheter introduced into the nasopharynx or oropharynx to a distance of 15 to 20 cm (6 to 8 in). • It can present insidiously or emergently at any time in the immediate postoperative period or up to several days after surgery The patient presents with hypotension; rapid, thready pulse; disorientation; restlessness; oliguria; and cold, pale skin. The early phase of shock will manifest in feelings of apprehension, decreased cardiac output, and vascular resistance. Breathing becomes labored, and “air hunger” will be exhibited; the patient will feel cold (hypothermia) and may experience tinnitus. Transfusing blood or blood products and determining the cause of hemorrhage are the initial therapeutic measures. The surgical site and incision should always be inspected for bleeding. If hemorrhage is suspected but cannot be visualized, the patient may be taken back to the OR for emergency exploration of the surgical site. • • • • Maintaining Cardiovascular Stability • To monitor cardiovascular stability, the nurse assesses the patient’s level of consciousness; vital signs; cardiac rhythm; skin temperature, color, and moisture; and urine output. • The primary cardiovascular complications seen in the PACU include hypotension and shock, hemorrhage, hypertension, and dysrhythmias. • In patients who are critically ill, have significant comorbidity, or have undergone riskier procedures, additional monitoring may have been done in the OR and will continue in the PACU Hypotension and Shock • Hypotension can result from blood loss, hypoventilation, position changes, pooling of blood in the extremities, or side effects of medications and anesthetics. • If the amount of blood loss exceeds 500 mL (especially if the loss is rapid), replacement is usually indicated. • Shock, which is one of the most serious postoperative complications, can result from hypovolemia and decreased intravascular volume (Gallagher & Vacchiano, 2014). o Types of shock are classified as hypovolemic, cardiogenic, neurogenic, anaphylactic, and septic. o The classic signs of hypovolemic shock (the most common type of shock) are pallor; cool, moist skin; rapid breathing; cyanosis of the lips, gums, and tongue; rapid, weak, thready pulse; narrowing pulse pressure; low blood pressure; and concentrated urine. o Hypovolemic shock can be avoided largely by the timely administration of IV fluids, blood, blood products, and medications that elevate blood pressure. ▪ The primary intervention for hypovolemic shock is volume replacement, with an infusion of lactated Ringer solution, 0.9% sodium chloride solution, colloids, or blood component therapy ▪ Oxygen is given by nasal cannula, facemask, or mechanical ventilation. If fluid administration fails to reverse hypovolemic shock, then various cardiac, vasodilator, and corticosteroid medications may be prescribed to improve cardiac function and reduce peripheral vascular resistance. • The patient is placed flat with the legs elevated, usually with a pillow. Respiratory rate, pulse rate, blood pressure, blood oxygen concentration, urinary output, and level of consciousness are monitored to provide information on the patient’s respiratory and cardiovascular status. • Other factors can contribute to hemodynamic instability, such as body temperature and pain Hemorrhage • Hemorrhage is an uncommon yet serious complication of surgery that can result in hypovolemic shock and death. • • Hypertension and Dysrhythmias • Hypertension is common in the immediate postoperative period secondary to sympathetic nervous system stimulation from pain, hypoxia, or bladder distention. • Dysrhythmias are associated with electrolyte imbalance, altered respiratory function, pain, hypothermia, stress, and anesthetic agents. Relieving Pain and Anxiety • The nurse in the PACU monitors the patient’s physiologic status, manages pain, and provides psychological support in an effort to relieve the patient’s fears and concerns. • IV opioids provide immediate pain relief and are short acting, thus minimizing the potential for drug interactions or prolonged respiratory depression while anesthetics are still active in the patient’s system Controlling Nausea and Vomiting • Nausea and vomiting occur in about 10% of patients in the PACU. • Many medications are available to control postoperative nausea and vomiting (PONV) without over-sedating the patient; they are commonly given during surgery as well as in the PACU Determining Readiness for Postanesthesia Care Unit Discharge • A patient remains in the PACU until fully recovered from the anesthetic agent. • Indicators of recovery include stable blood pressure, adequate • respiratory function, and adequate oxygen saturation level compared with baseline.

Promoting Home, Community-Based, and Transitional Care • To ensure patient safety and recovery, expert patient education and discharge planning are necessary when a patient undergoes same-day or ambulatory surgery • Alternative formats (e.g., large print, Braille) of instructions or the use of a sign language interpreter may be required to ensure patient and family understanding. • Although recovery time varies depending on the type and extent of surgery and the patient’s overall condition, instructions usually advise limited activity for 24 to 48 hours. • During this time, the patient should not drive a vehicle, drink alcoholic beverages, or perform tasks that require high levels of energy or skill. • Patients are cautioned not to make important decisions at this time because the medications, anesthesia, and surgery may affect their decision-making ability. • Although most patients who undergo ambulatory surgery recover quickly and without complications, some patients require referral for some type of continuing or transitional care. o Nursing interventions may include changing surgical dressings, monitoring the patency of a drainage system, or administering medications. o The patient and family are reminded about the importance of keeping follow-up appointments with the surgeon. o Follow-up phone calls from the nurse are also used to assess the patient’s progress and to answer any questions. Care of the Hospitalized Postoperative Patient • Most surgeries are now performed in ambulatory care centers, but there are unanticipated transfers of some patients for hospitalization (Allison & George, 2014). • • • However, the majority of surgical patients who require hospital stays are trauma patients, acutely ill patients, patients undergoing major surgery, patients who require emergency surgery, and patients with a concurrent medical disorder. Seriously ill patients and those who have undergone major cardiovascular, pulmonary, or neurologic surgery may be admitted to specialized ICUs for close monitoring and advanced interventions and support. Patients admitted to the clinical unit for postoperative care have multiple needs and stay for a short period of time. Receiving the Patient in the Clinical Unit • The patient’s room is readied by assembling the necessary equipment and supplies: IV pumps, drainage receptacle holder, suction equipment, oxygen, emesis basin, tissues, disposable pads, blankets, and postoperative documentation forms. • Usually, the surgeon speaks to the family after surgery and relates the general condition of the patient. Nursing Management After Surgery • During the first 24 hours after surgery, nursing care of the hospitalized patient on the medical-surgical unit involves continuing to help the patient recover from the effects of anesthesia • The pulse rate, blood pressure, and respiration rate are recorded at least every 15 minutes for the first hour and every 30 minutes for the next 2 hours. • Patients usually begin to return to their usual state of health several hours after surgery or after awaking the next morning. • Although pain may still be intense, many patients feel more alert, less nauseous, and less anxious. PREVENTING RESPIRATORY COMPLICATIONS • Respiratory depressive effects of opioid medications, decreased lung expansion secondary to pain, and decreased mobility combine to put the patient at risk for respiratory complications, particularly atelectasis (alveolar collapse; incomplete expansion of the lung), pneumonia, and hypoxemia (Rothrock, 2014). • Atelectasis remains a risk for the patient who is not moving well or ambulating or who is not performing deep breathing and coughing exercises or using an incentive spirometer. • Hypostatic pulmonary congestion, caused by a weakened cardiovascular system that permits stagnation of secretions at lung bases, may develop; this condition occurs most frequently in older patients who are not mobilized effectively • The types of hypoxemia that can affect postoperative patients are subacute and episodic. • To clear secretions and prevent pneumonia, the nurse encourages the patient to turn frequently, take deep breaths, cough, and use the incentive spirometer at least every 2 hours. • Coughing is contraindicated in patients who have head injuries or who have undergone intracranial surgery (because of the risk for increasing intracranial pressure), as well as in patients who have undergone eye surgery (because of the risk for increasing intraocular pressure) or plastic surgery (because of the risk for increasing tension on delicate tissues). RELIEVING PAIN • Most patients experience some pain after a surgical procedure. Complete absence of pain in the area of the surgical incision may not occur for a few weeks, depending on PADUA, JAKE DONELY P. BSN 3-1 (THIRD YEAR) NUR 312 1st sem | AY 2023-2024 • • • Topic: TEXTBOOK OF MED-SURG NURSING (UNIT 4) Author: BRUNNER AND SUDDARTH’S the site and nature of the surgery, but the intensity of postoperative pain gradually subsides on subsequent days. Many factors (motivational, affective, cognitive, emotional, and cultural) influence the pain experience (Rodriguez, 2015). The degree and severity of postoperative pain and the patient ’s tolerance for pain depend on the incision site, the nature of the surgical procedure, the extent of surgical trauma, the type of anesthesia, and the route of administration. Intense pain stimulates the stress response, which adversely affects the cardiac and immune systems. When pain impulses are transmitted, both muscle tension and local vasoconstriction increase, further stimulating pain receptors. PROMOTING CARDIAC OUTPUT • Although most patients do not hemorrhage or go into shock, changes in circulating volume, the stress of surgery, and the effects of medications and preoperative preparations all affect cardiovascular function. • IV fluid replacement may be prescribed for up to 24 hours after surgery or until the patient is stable and tolerating oral fluids. ENCOURAGING ACTIVITY • Early ambulation has a significant effect on recovery and the prevention of complications (e.g., atelectasis, hypostatic pneumonia, gastrointestinal [GI] discomfort, circulatory problems) (Rothrock, 2014). • When a patient gets out of bed for the first time, orthostatic hypotension, also called postural hypotension, is a concern. Orthostatic hypotension is an abnormal drop in blood pressure that occurs as the patient changes from a supine to a standing position. • To assist the postoperative patient in getting out of bed for the first time after surgery, the nurse: o 1. Helps the patient move gradually from the lying position to the sitting position by raising the head of the bed and encourages the patient to splint the incision when applicable. o 2. Positions the patient completely upright (sitting) and turned so that both legs are hanging over the edge of the bed. o 3. Helps the patient stand beside the bed. • Whether or not the patient can ambulate early in the postoperative period, bed exercises are encouraged to improve circulation. Bed exercises consist of the following: o Arm exercises (full range of motion, with specific attention to abduction and external rotation of the shoulder) o Hand and finger exercises o Foot exercises to prevent VTE, footdrop, and toe deformities and to aid in maintaining good circulation o Leg flexion and leg-lifting exercises to prepare the patient for ambulation o Abdominal and gluteal contraction exercises WOUND HEALING • First-Intention Healing Wounds- made aseptically with a minimum of tissue destruction that are properly closed heal with little tissue reaction by first intention (primary union). When wounds heal by first-intention healing, granulation tissue is not visible and scar formation is minimal. Postoperatively, many of these wounds are covered with a dry sterile dressing. If a cyanoacrylate tissue adhesive (LiquiBand) has been used to close the incision without sutures, a dressing is contraindicated. • • Second-intention healing (granulation) occurs in infected wounds (abscess) or in wounds in which the edges have not been approximated. When an abscess is incised, it collapses partly, but the dead and dying cells forming its walls are still being released into the cavity. For this reason, a drainage tube or gauze packing is inserted into the abscess pocket to allow drainage to escape easily. Third-intention healing (secondary suture) is used for deep wounds that either have not been sutured early or break down and are resutured later, thus bringing together two opposing granulation surfaces. This results in a deeper and wider scar. These wounds are also packed postoperatively with moist gauze and covered with a dry sterile dressing. CARING FOR WOUNDS • Wound Healing. Wounds heal by different mechanisms, depending on the condition of the wound. Surgical wound healing may occur in three ways, by first-intention, secondintention, and third-intention wound healing • Caring for Surgical Drains. Nursing interventions to promote wound healing also include management of surgical drains. Drains are tubes that exit the peri-incisional area, either into a portable wound suction device (closed) or into the dressings (open). The principle involved is to allow the escape of fluids that could otherwise serve as a culture medium for bacteria. Types of wound drains include the Penrose, Hemovac, and Jackson-Pratt drains • Changing the Dressing. Although the first postoperative dressing is usually changed by a member of the surgical team, subsequent dressing changes in the immediate postoperative period are usually performed by the nurse. A dressing is applied to a wound for one or more of the following reasons: o (1) to provide a proper environment for wound healing; o (2) to absorb drainage; o (3) to splint or immobilize the wound; o (4) to protect the wound and new epithelial tissue from mechanical injury; o (5) to protect the wound from bacterial contamination and from soiling by feces, vomitus, and urine; o (6) to promote hemostasis, as in a pressure dressing; and o (7) to provide mental and physical comfort for the patient. MAINTAINING NORMAL BODY TEMPERATURE • The patient is still at risk for malignant hyperthermia and hypothermia in the postoperative period. • Efforts are made to identify malignant hyperthermia and to treat it early and promptly • Hypothermia management, begun in the intraoperative period, extends into the postoperative period to prevent significant nitrogen loss and catabolism MANAGING GASTROINTESTINAL FUNCTION AND RESUMING NUTRITION • Discomfort of the GI tract (nausea, vomiting, and hiccups) and resumption of oral intake are issues for the patient and affect their outcome following surgery. • If the risk of vomiting is high due to the nature of surgery, a nasogastric tube is inserted preoperatively and remains in place throughout the surgery and the immediate postoperative period. • Hiccups, produced by intermittent spasms of the diaphragm secondary to irritation of the phrenic nerve, can occur after surgery PADUA, JAKE DONELY P. BSN 3-1 (THIRD YEAR) NUR 312 1st sem | AY 2023-2024 Topic: TEXTBOOK OF MED-SURG NURSING (UNIT 4) Author: BRUNNER AND SUDDARTH’S PROMOTING BOWEL FUNCTION • Constipation can occur after surgery as a minor or a serious complication. • Decreased mobility, decreased oral intake, and opioid analgesic medications can contribute to difficulty having a bowel movement. • The nurse should assess the abdomen for distention and the presence and frequency of bowel sounds. If the patient does not have a bowel movement by the second or third postoperative day, the primary provider should be notified and a laxative or other test or intervention may be needed. MANAGING VOIDING • Urinary retention after surgery can occur for various reasons. • Anesthetics, anticholinergic agents, and opioids interfere with the perception of bladder fullness and the urge to void and inhibit the ability to initiate voiding and completely empty the bladder. • Bladder distention and the urge to void should be assessed at the time of the patient’s arrival on the unit and frequently thereafter. The patient is expected to void within 8 hours after surgery • The bedpan should be warm; a cold bedpan causes discomfort and automatic tightening of muscles • If the patient has not voided within the specified time frame, an ultrasound bladder scan or bladder ultrasonography is performed to check for urinary retention • Even if the patient voids, the bladder may not necessarily be empty. • • deep body tissues to pathogens in the environment places the patient at risk for infection of the surgical site, and a potentially life-threatening complication such as infection can increase the length of hospital stay, costs of care, and risk of further complications. Wound Dehiscence and Evisceration. Wound dehiscence (disruption of surgical incision or wound) and evisceration (protrusion of wound contents) are serious surgical complications (see Fig. 19-6). Dehiscence and evisceration are especially serious when they involve abdominal incisions or wounds. These complications result from sutures giving way, from infection, or, more frequently, from marked distention or strenuous cough. They may also occur because of increasing age, anemia, poor nutritional status, obesity, malignancy, diabetes, the use of steroids, and other factors in patients undergoing abdominal surgery (Meiner, 2014). Continuing and Transitional Care. Community-based and transitional care services are frequently necessary after surgery. Older patients, patients who live alone, patients without family support, and patients with preexisting chronic illness or disabilities are often in greatest need. Planning for discharge involves arranging for necessary services early in the acute care hospitalization for wound care, drain management, catheter care, infusion therapy, and physical or occupational therapy. The home, community-based, or transitional care nurse coordinates these activities and services. MAINTAINING A SAFE ENVIRONMENT • During the immediate postoperative period, the patient recovering from anesthesia should have three side rails up, and the bed should be in the low position. • The nurse assesses the patient’s level of consciousness and orientation and determines whether the patient can resume wearing assistive devices as needed • Vascular surgeries, such as replacement of sections of diseased peripheral arteries or insertion of an arteriovenous graft, put the patient at risk for thrombus formation at the surgical site and subsequent ischemia of tissues distal to the thrombus. MANAGING POTENTIAL COMPLICATIONS • Venous Thromboembolism. Serious potential VTE complications of surgery include DVT and PE (Rothrock, 2014). Prophylactic treatment is common for patients at high risk for VTE. Dehydration, low cardiac output, blood pooling in the extremities, and bed rest add to the risk of thrombosis formation. The first symptom of DVT may be a pain or cramp in the calf although many patients are asymptomatic. Initial pain and tenderness may be followed by a painful swelling of the entire leg, often accompanied by fever, chills, and diaphoresis • Hematoma. At times, concealed bleeding occurs beneath the skin at the surgical site. This hemorrhage usually stops spontaneously but results in clot (hematoma) formation within the wound. If the clot is small, it will be absorbed and need not be treated. If the clot is large, the wound usually bulges somewhat, and healing will be delayed unless the clot is removed. • Infection (Wound Sepsis). The creation of a surgical wound disrupts the integrity of the skin, bypassing the body’s primary defense and protection against infection. Exposure of PADUA, JAKE DONELY P. BSN 3-1 (THIRD YEAR)
