What are some causes of: • Transudative • Exudative Etiology: Pleural Effusion Identify the Class of Effusion Disease Process Classification of Effusion Heart Failure TB Lupus/RA Renal Disease Lung Cancer Trauma Pneumonia Liver Failure 15 Clinical Manifestations: Pleural Effusion • • • • • Dyspnea Pleurisy Decreased breath sounds Decreased chest wall movement Dullness on percussion 16 17 How do we diagnosis pleural effusions? Pleural Effusion -- Diagnositcs • • • • ____________ ____________ ____________ ____________ How do we know what type of pleural effusion it is? Interventions: Pleural Effusion • Thoracentesis Diagnostic vs. Therapeutic 23 Interventions: Pleural Effusion 24 Interventions: Pleural Effusion 25 Interventions: Pleural Effusion 26 Interventions: Pleural Effusion Treat underlying condition – CHF/Renal failure Pneumonia Liver Disease Lupus/RA Malignancy Pleurodesis Chest tube insertion Allow to resolve 27 Complications of Pleural Effusion • Trapped Lung • Recurrent effusions • Pneumothorax PNEUMOTHORAX • 3 types – Closed – Open – Iatrogenic Closed Pneumothorax No opening from external chest. Open Pneumothorax Opening from external chest wall into pleura. Iatrogenic Pneumothorax Puncture or laceration of visceral pleura during medical tx Occurs in crashes, falls, MVAs, CPR, fractured ribs that penetrate the pleura. Occurs in stabbings, gunshot wounds, impalement injury. Occurs in central line placement, thoracentesis, lung biopsy, bronchoscopy, & mechanical ventilation 30 ww http://images.google.com/imgres?imgurl=http://graphics8.nytimes.com/images/2007/0 8/01/health/adam/15210.jpg&imgrefurl=http://www.nytimes.com/slideshow/2007/08/01/ health/100150Pneumothoraxseries_4.html&usg=__VZn79dHtqdr7izJf1jBM0r5R4ig=&h =320&w=400&sz=44&hl=en&start=3&sig2=06HaoI7v1pH1SPxnpU_4Vg&um=1&tbnid =l0LTfAdhVxUVSM:&tbnh=99&tbnw=124&prev=/images%3Fq%3Dblebs%2Bon%2Blu ngs%2Bcausing%2Bpneumothorax%26hl%3Den%26rlz%3D1T4DMUS_enUS282US2 82%26sa%3DN%26um%3D1&ei=lGWJSvXaGIawtAOVxtidBw Clinical Manifestations: Pneumothorax • Respiratory • Cardiac 32 Tension Pneumothorax • Air/blood/fluid rapidly entering the pleural space • Lung collapses • Emergency situation 33 Pathophysiology: Tension Pneumo • Increase in intrapleural pressure • Compression of lung • Compresses against trachea, heart, aorta, esophagus • Ventilation and cardiac output greatly compromised 34 Clinical Manifestations: Tension Pneumo • • • • • • • • Severe dyspnea Tracheal deviation Decreased cardiac output Distended neck veins Increased respiratory rate Increased heart rate Decreased blood pressure Shock 35 Treatment Tension Pneumo • Emergency --- quick intervention – Needle decompression – Chest tube placement Other Types • Hemothorax • Chylothorax Intervention: Pneumothorax • • • • • • High Fowlers position Oxygen as ordered Rest to decrease oxygen demand ***Chest tube insertion Pleurodesis Surgery ? 38 Trauma of the Chest/Lung • What is involved • • • • Chest wall Lungs Heart and great vessels Esophagus • Airway obstruction • Pneumothorax • Flail chest 39 Clinical Manifestations: Rib Fractures • • • • • • Ribs 5-10 most commonly fractured Pain Splinting & Rapid, shallow respirations Decreased breath sounds Crepitus Signs/symptoms of pneumothorax 40 Treatment: Rib Fractures • • • • Reduce or minimize pain Do we wrap or bind the chest? Do we use opiods? Goal? Pathophysiology: Flail Chest • 2 or more ribs fractured • 2 or more separate places • Unstable / free floating chest • Usually involves anterior or lateral fx • Paradoxical respirations 42 Clinical Manifestations: Flail Chest • Dyspnea with rapid, shallow inspiration • Pain • Palpable crepitus • Decreased breath sounds • Unequal chest expansion • Tachycardia 43 Interventions: Flail Chest • • • • • • • Oxygen as ordered Elevate HOB Analgesia Suction Splint affected side *Intubation *Mechanical ventilation Pathophysiology: Pulmonary Contusion Abrupt chest compression then rapid decompression Intra-alveolar hemorrhage Interstitial/bronchial edema Decrease surfactant production Increase pulmonary vascular resistance Decrease blood flow 45 Clinical Manifestation: Pulmonary Contusion • • • • • • • • • Increased SOB Restlessness Anxiety Chest pain Copious sputum Increased respiratory Increased heart rate Dyspnea Cyanosis 46 Intervention: Pulmonary Contusion • • • • • • Intubation Mechanical ventilation Bronchoscopy Fluids Volume expanders Pulmonary artery pressure monitoring 47
