Thoracic Cavity 2 http://www.google.com/imgres?imgurl=http://www.tcnj.edu/~mckinney/body.jpg&imgrefurl=http://www.tcnj.edu/~m ckinney/breathing.htm&h=480&w=460&sz=60&tbnid=7I0hIqYYrrrEDM:&tbnh=129&tbnw=124&prev=/images%3F q%3Dthoracic%2Bcavity&usg=__64_qfRrbnmkZHJsDtcpsNyD- QUk=&ei=HjqESrfvF4eosgPnloGqBw&sa=X&oi=image_result&resnum=4&ct=image

3. Normal Anatomy Thoracic cavity Chest wall Pleural space Fluid 3

4. Terminolgy Pleura – the thin serous membrane around the lungs and inner walls of the chest (2 layers) Pleural space – thin space between the 2 layers of pleura Pleural cavity – body cavity that surrounds the lungs Pleural Fluid – pleura that lines the inner chest wall and covers the diaphragm

5. Pleural Fluid pH 7.6 – 7.64 1-2g/dL protein Less than 1000 WBC per cubic millimeter Glucose level similar to plasma LDH less than 50% that of plasma Na, K+, & Ca levels similar to that of interstitial fluid

6. Viceral pleura – – Covers surface of the lung – Cannot be disected away from the lung Parietal pleura- – Lines the wall of the chest and covers the diaphragm http://www.themesotheliomalibrary.com/pleural-effusions.JPG

7. Chest Trauma & Thoracic Injury 20-25% of trauma victims with chest trauma die 45% of trauma victims have some type of chest trauma BEWARE: External injury may appear minor 7

8. Categories for Traumatic Injuries Blunt trauma Penetrating trauma

9. Traumatic Chest Injuries Mechanism of InjuryCommon Related Injury Blunt Trauma Blunt steering wheel injury to chestRib fractures, flail chest, pneumothorax, hemopneumothorax, myocardial contusion, pulmonary contusion, cardiac tamponade, great vessel tears Shoulder harness seat belt injuryFractured clavicle, dislocated shoulder, rib fractures, pulmonary contusion, pericardial contusion, cardiac tamponade Crush injury (heavy equipment, crushing the thorax) Pneumothorax and hemopneumothorax, flail chest, great vessel tears and rupture, decreased blood return to heart with decreased cardiac output Penetrating trauma Gunshot, stab wound to chestOpen pneumothorax, tension pneumothorax, hemopneumothorax, cardiac tamponade, esophageal damage, tracheal tear, great vessel tears 9

10. What needs to be done? Client comes to ED following a MVA Assessment Respiratory Cardiovascular Surface findings Interventions Monitoring Diagnostic Test 10

11. Respiratory Disorders: Pleural and Thoracic Injury Pleural Effusion A collection of excess fluid in the pleural space Classification Transudative aka: hydorthoraces Exudative 11

12. 12 Pathophysiology of Pleural Effusion hydrostatic pressure or oncotic pressure Formation of excess fluid= Transudate capillary permeability Formation of fluid & cells= Exudate

13. Empyema What is it? What causes it? How do we treat it?

14. What are some causes of: Transudative Exudative

15. Etiology: Pleural Effusion Identify the Class of Effusion Disease ProcessClassification of Effusion Heart Failure TB Lupus/RA Renal Disease Lung Cancer Trauma Pneumonia Liver Failure 15

16. Clinical Manifestations: Pleural Effusion Dyspnea Pleurisy Decreased breath sounds Decreased chest wall movement Dullness on percussion 16

17. 17

18. How do we diagnosis pleural effusions?

19. Pleural Effusion -- Diagnositcs ____________

22. How do we know what type of pleural effusion it is?

23. Interventions: Pleural Effusion Thoracentesis Diagnostic vs. Therapeutic 23

24. Interventions: Pleural Effusion 24

25. Interventions: Pleural Effusion 25

26. Interventions: Pleural Effusion 26

27. Interventions: Pleural Effusion Treat underlying condition – CHF/Renal failure Pneumonia Liver Disease Lupus/RA Malignancy Pleurodesis Chest tube insertion Allow to resolve 27

28. Complications of Pleural Effusion Trapped Lung Recurrent effusions Pneumothorax

29. PNEUMOTHORAX 3 types – Closed – Open – Iatrogenic

30. 30 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

32. Clinical Manifestations: Pneumothorax Respiratory Cardiac 32

33. Tension Pneumothorax Air/blood/fluid rapidly entering the pleural space Lung collapses Emergency situation 33

34. Pathophysiology: Tension Pneumo Increase in intrapleural pressure Compression of lung Compresses against trachea, heart, aorta, esophagus Ventilation and cardiac output greatly compromised 34

35. 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

36. Treatment Tension Pneumo Emergency --- quick intervention – Needle decompression – Chest tube placement

37. Other Types Hemothorax Chylothorax

38. Intervention: Pneumothorax High Fowlers position Oxygen as ordered Rest to decrease oxygen demand ***Chest tube insertion Pleurodesis Surgery ? 38

39. Trauma of the Chest/Lung What is involved Chest wall Lungs Heart and great vessels Esophagus Airway obstruction Pneumothorax Flail chest 39

40. Clinical Manifestations: Rib Fractures Ribs 5-10 most commonly fractured Pain Splinting & Rapid, shallow respirations Decreased breath sounds Crepitus Signs/symptoms of pneumothorax 40

41. Treatment: Rib Fractures Reduce or minimize pain Do we wrap or bind the chest? Do we use opiods? Goal?

42. 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

43. Clinical Manifestations: Flail Chest Dyspnea with rapid, shallow inspiration Pain Palpable crepitus Decreased breath sounds Unequal chest expansion Tachycardia 43

44. Interventions: Flail Chest Oxygen as ordered Elevate HOB Analgesia Suction Splint affected side *Intubation *Mechanical ventilation 44

45. 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

46. Clinical Manifestation: Pulmonary Contusion Increased SOB Restlessness Anxiety Chest pain Copious sputum Increased respiratory Increased heart rate Dyspnea Cyanosis 46

47. Intervention: Pulmonary Contusion Intubation Mechanical ventilation Bronchoscopy Fluids Volume expanders Pulmonary artery pressure monitoring 47
