Respiratory Stressors I Pulmonary Embolism Lung Cancer Thoracic Surgery Chest Tubes Pleural Effusions J Borrero 2/09 NUR240 Pulmonary Embolism Pulmonary Embolism -emboli that reach the lungs and obstruct pulmonary circulation -blood, air, fat, tumor cells, amniotic fluid, foreign objects -many die within 1 hr of onset of symptoms or before dx. Risk Factors for PE Virchow’s Triad of causes DVT and PE 1. Stasis of blood flow 2. Endothelial injury 3. Hypercoagulability What else???? Symptoms of a PE Chest pain with respirations S3 or S4 heart sounds EKG-non specific- T or ST abnormalities SOB-crackles, friction rub, breath sounds Dyspnea, hemoptysis, CP in<20% pts. Mild temp with sweating Shock: Tachycardia, hypotension, skin cold/clammy N&V Feeling of anxiety, impending doom, restlessness Assessment Laboratory: Elevated WBCs ABGs-Resp alkalosis Resp.acidosis. O2 Sats low CXR EKG Ventilation/Perfusion Scan CT Scan or CTA “Gold Standard” Pulmonary angiography- invasive Thoracentesis Management- Non surgical Nursing Dx: ABG analysis Prevention of DVT, prophylactic use of heparin Thrombolytic agents for massive clots O2, VS, lung/heart sounds, Mechanical ventilation Assess bleeding risk Nursing Diagnosis 1.Decreased Cardiac Output R/T … IVF Positive inotropic agents Vasodilators Outcome:Adequate tissue perfusion in all major organs Predictors: Adequate circulation Predictors: Nursing Diagnoses 2. Risk for injury (bleeding) R/T… Maintain H&H WNL Monitoring and pt. teaching 3. Anxiety R/T… Verbalization of fears Teach coping mechanisms Management Stable pts- Heparin for 5-10 days, then Coumadin started on the third day (from 3-6 weeks or indefinitely) Health Teaching Management- Surgical Embolectomy-removal of clot IVC fillter Heparin Protocol Dosage Calculations based on actual body weight. (round to nearest weight in dosing table i.e. if halfway or more to next weight round up, if less than halfway round down) 1. Heparin 25,000 units in 250 mL (100 units/mL) of ½ NS 2. Initial IV LOADING DOSE 3. Initial IV INFUSION RATE 4. WARFARIN will be started: No Yes at ________ mg P.O. daily, to start on second day of heparin. 5. LABS: CBC with platelets now & every 3 days beginning in a.m. PTT now and treat according to scale below. Pro time daily only if Warfarin started. 6. ADJUST heparin infusion based on sliding scale below: Target PTT = 71 – 123 seconds 7. MANAGEMENT *a. When two consecutive PTT's are within a 71123 range, order PTT every twenty-four hours (at least 4 hours after last PTT drawn). b. No adjustments are to be made for PTT's drawn less than 4 hours after the last heparin dose adjustment. c. Document all rate changes on MAR. Make changes as promptly as possible. 8. MONITORING a. Assess patient for bleeding every shift. b. Notify physician on rounds (STAT if unstable) if: any unscheduled interruptions in heparin infusion platelets less than 100,000/mm3 or decrease of 50,000/mm3 hemoglobin less than 10 gm/dL or decrease of 2 gm/dL significant bleeding patient suffers trauma or fall Lung Cancer Leading cancer killer for men and women Number of men has stayed stable but number of women continues to rise Lung cancer has surpassed breast cancer as the major killer of women and remains at the top of the list 70% have mets at time of dx. Long term survival is low. Most die within 1yr of dx 5 year survival rate is <15% Leading cause of cancerrelated deaths worldwide Kills more women than breast, ovarian and uterine combined Rate of lung Ca among women has not been declining as in men…but women are more likely to survive the disease No rationale offered for the difference The rate of lung Ca among non-smokers is increasing, esp. young women, reason is unclear New studies have identified some causes of increased incidence Risk Factors for Lung Cancer 85% are caused by inhalation of carcinogenic chemicals Cigarette smoke has 43 known chemical carcinogens Directly related to pack-years Second hand smoke is also a risk factor Exposure to ionizing radiation Air pollution (2-3x risk in urban areas) Chronic exposure to asbestos, coal distillates and radiation Genetic predisposition Underlying respiratory disease- COPD or TB Pathophysiology of Lung Ca Epithelial cell is attacked by carcinogen and binds to the cell’s DNA and damages it The cells mutate, have abnormal cell growth and develop into malignant cells The cells replicate and continue to change, causing the pulmonary epithelium to become an invasive carcinoma Metastasize by direst extension through blood and by invading lymph gland and vessels Lung Ca Classification 1.Small cell lung cancer (SCLC) or oat cell -2% of all lung Ca -99% associated with cigarette smoking -fast growing 2. Non small cell lung cancer (NSCLC) - has the best survival rate if tx early - includes squamous cell, adenocarcinoma and large cell cancer Assessment History Risk Factors Respiratory Assessment Presence of Abnormal findings: Inspection Palpation Percussion Auscultation Psychosocial Assessments Warning Signs Persistant cough or change in cough Change in resp pattern Hemoptysis Wheezing/dyspnea Blood streaked sputum Chest pain- dull or pleuritic Hoarseness or dysphagia Recurrent episodes of PN, Pleural effusion Compression of SVC Weight loss Clubbing of the fingers Clinical Manifestations Paraneoplastic- additional manifestation caused by hormones secreted by tumor cells 1.Endocrine Hypercalcemia Cushing’s Syndrome SIADH- Syndrome of Inappropriate Antidiuretic Hormone Ectopic Insulin- Hypoglycemia Clinical Manifestations 2.

Preset at -20cm H20 Heimlich valve- is a one way flutter valve made of rubber tubing in a plastic chamber. Chest Drainage Water in the second chamber acts as a seal and allows air and fluid to drain from the chest into the first chamber but cannot reenter the chest tube Think of a cup of water and a straw. If you blow bubbles into a submerged straw, air would bubble out through the water. Now if you wanted to draw back air through the straw, you would only draw water Drainage accumulates in the first chamber and air exits through the second chamber. The first chamber remains empty in case of pneumothorax Chest Drainage The water level fluctuates as the pt breathes (tidaling) Up on inhalation Down on exhalation Outside suction may be added to promote drainage of fluid and removal of air Addition of suction creates constant bubbling in 3rd chamber If bubbling occurs in the absence of suction there may be a leak in the system Nursing Care Assess patency of CT/ Pleurovac Keep 2 padded clamps and bottle of sterile H2O at bedside Vaseline and sterile gauze Assess amt/type of chest drainage q1h 1st 24hrs. Notify MD >100/hr Assess respiratory status Assessment of Water Seal Function Fluctuation of fluid in water seal compartment during respiration is normal If tidaling does not occur- observe for bubbling, possible leak Rapid bubbling in absence of leakEMERGENCY-notify MD May have loss of air from incision or tear in pleura Care of the Chest Tube and Drainage System System kept below the insertion site If postitioning pt on affected side, check for kinks & occluded tubing Tape all connections securely with adhesive tape Coil tube at pts side Monitor tension on tubing when pt sits up or turns over If unit accidentally tips over, stand it up right away If drainage has moved from the collection chamber, replace unit Change dsg prn, monitor insertion site Documentation Duration and Removal of CT Duration of CT is dependent upon CXR Normal Resp Status Drainage <100ml/24 hr Place occlusive dsg over insertion site Monitor pt CXR Change dsg prn Chest Tube Complications Dislodged Tube from Chest Wall 1.Apply pressure over insertion site 2.Notify MD 3.Have pt cough forcefully and cover wound with vaseline gauze and DSD 4.Tape on 3 sides only 5.Stay with pt and assess for resp distress 6.Prepare for CT reinsertion 7.If S&S of tension pneumo/mediastinal shift are present, release dsg to let air escape Interventions for Emergency Situations Disconnected Chest Tubes- check agency policy Clean both ends with alcohol and allow to dry Reconnect and tape Assess continuously for resp distress Anticipate a STAT portable CXR Interventions for Emergency Situations Tension Pneumothorax Assess for resp distress, tracheal shift, diminished to absent breath sounds, assymetrical breathing, hypotension, pain Assure system is patent, not clamped or obstructed Notify MD STAT and increase O2 Prepare for needle thoracostomy (14G ) Stay with pt and assess continuously Place in hi fowler’s if not contraindicated Prepare for ABG and/or CXR Interventions for Emergency Situations Disconnection from drainage system Submerge open end of the chest tube in sterile water Prepare new equipment and attach, use adhesive tape Wipe ends with alcohol and allow to dry Chest tube becomes obstructed by clot Observe tubing for signs of clot, decreased flow of fluid through tube Gentle milking of tube, do not strip Pleuritis Inflammation of the pleura generally 2nd to viral respiratory illness, pneumonia or rib injury. Self limiting and short duration Pain unilateral and localized, sharp or stabbing, may refer to neck or shoulder Dx: based on presenting symptoms. CXR and EKG to r/o other problems Tx: Analgesics and NSAIDS. Codeine for pain and to suppress cough Report increased fever, productive cough, dyspnea or SOB Pleural Effusions Excess fluid in pleural space Systemic Causes: CHF, liver or renal disease, connective tissue disorders RA and SLE Local Causes: PN, atelectasis, TB, lung CA and trauma Pleural Effusions The accumulated fluid can be transudate or exudate: Transudate: protein free fluid forced from lung by increased (overload) pressures in the lung “weeps out” Heart failure, ascites from liver failure, renal disease, PN Exudate: contains cells > 3% proteins Inflammation, infection, malignancy in pleural space, TB, pancreatitis, subphrenic abscess, empyema Pleural Effusions Symptoms- dyspnea, pleuritic CP Diagnosis- diminished BS, dullness over effusion CXR/CT/Ultrasound- to differentiate, localize pleural effusions Thoracentesis- analysis of pleural fluid Fluid removal is limited to 1200-1500cc to prevent cardiovascular collapse, relieve symptoms -may be diagnostic, cells are sent for cultures -done under radiology or ultrasound Pleural Effusions Chemical Pleurodesis- tx to prevent recurrence of pleural effusions A sclerosing agent is instilled. Creates an inflammation that causes adhesions between the pleura layers so no fluid can accumulate there.
