    1. 1. CHEST INJURIES
    2. 2. AWARENESS• Mortality: Thoracic injuries are responsible for 25% of trauma deaths (UK)• Thoracotomy is required in – 10% of blunt injuries – 20% of penetrating injuries• Early recognition and management are key to patient survival
    3. 3. Mortality1st peak 2nd peak 3rd peak
    4. 4. Tri-modal peak of Mortality• 1st peak: Non-survivable severe CNS or CVS injuries – Location of death: Pre-hospital environment• 2nd peak: First few hours after injury, most often due to hypoxiais referred to as Hence this and hypovolemic shock “THE GOLDEN HOUR” – Large proportion(1/3) of these patients can be saved by EMS (Emergency Medical Services).• 3rd peak: Within 6 weeks of injury – Cause: Multisystem failure and sepsis
    5. 5. The ATLS concept• Advanced Trauma Life Support (ATLSTM) by the American College of Surgeons Committee on Trauma• Originated 1976, Dr. James Styner.
    6. 6. Three Stage Approach1. Primary Survey: Rapid Assessment and treatment of immediately life threatening injuries2. Secondary Survey: Detailed head-to toe assessment of potentially life threatening injuries3. Definitive Care: Specialist treatment of identified injuries
    7. 7. Initial AssessmentA. Airway with cervical spine protectionB. BreathingC. Circulation with haemorrhage controlD. Disability or neurological statusE. Exposure and Environment – remove clothing, but keep warm
    8. 8. B-Breathing and Chest Injuries Primary Survey: ARM approach1. Awareness,2. Recognition3. and Management
    9. 9. Recognition (Clinical Features) Look Listen Feel
    10. 10. LOOK – Respiratory rate – Shallow, gasping or laboured breathing: Respiratory failure? – Cyanosis: Hypoxia – Paradoxical Respiration: ‘Pendulum’ breathing with asynchronisation of chest and abdomen: Respiratory failure or Structural damage. – Unequal chest inflation: Pneumothorax or Flail chest – Bruising or contusion: ‘Seat-Belt’ sign. – Penetrating chest injury – Distended neck veins: venous return-Tension pneumothorax or cardiac tamponade
    11. 11. LISTEN- Absent breath sounds: Apnoea or tension pneumothorax- Noisy breathing/ Crepitations/ Stridor/ Wheeze: Partially obstructed airway- Reduced air entry: Pneumothorax, Haemothorax, Heamo- pnemothorax, flail chestFEEL- Tracheal devitation: Mediastinal shift- Tenderness: Chest wall contusion and/ rib #- Crepitus/Instabilty: Underlying rib #
    12. 12. Immediately Life-Threatening Chest Injuries (Primary Survey)1. Tension Pneumothorax2. Open Pneumothorax (sucking chest wound)3. Massive Haemothorax4. Cardiac Tamponade5. Flail Chest6. Disruption of Tracheo-Brochial tree
    13. 13. Potentially Life-Threatening Chest Injuries (Secondary Survey)1. Pulmonary contusion2. Myocardial contusion3. Aortic disruption4. Diaphragmatic rupture5. Tracheobronchial rupture6. Oesophageal rupture
    14. 14. Adjuncts1. Vital signs2. ECG3. Pulse oximetry4. End-Tidal Carbon Dioxide5. Arterial Blood Gas6. Urinary output7. Urethral Catheterization8. Nasogastric tube9. Chest X-Ray10.Pelvic X-Ray
    15. 15. Rib fracture
    16. 16. Introduction• 1st and 2nd ribs , protected by clavicle: when fractured are very ominous as they indicate transection of thoracic aorta or damage to brachial plexus or subclavian vein• 11th and 12th ribs are floating ribs, usually not fractured• Ribs in children are more elastic thus great force needed
    17. 17. Types of trauma• Closed injury to the chest Direct trauma • Single or multiple ribs fractured at the point of contact Crush injury • Usually causes flail chest due to multiple sites of fracture of ribs Steering wheel injury • In head on car accidents where fracture of sternum and bilateral fractures of ribs at costochondral junction Minor trauma • In osteoporotic ribs, sometimes even a cough can cause a rib fracture
    18. 18. Clinical features• In rib fracture without complication: Pain while taking a deep breath and exaggerated pain during coughing• Inspection: Bruising• Palpation: Bony irregularity, Tenderness and Crepitus• X-ray usually shows a fracture rib but may miss a hairline fracture• Radioscintigraphy: Detected a week or two after injury• Always rule out the presence of complications and monitor the patient before diagnosing an isolated rib #
    19. 19. Treatment of uncomplicated rib fracture• Reduction of pain with 2 week follow up• Analgesics : – Opiods – NSAID’s• Intercostal Blocks• Strapping of chest: relieves pain by immobilizing the ribs• Breathing exercises
    20. 20. • Strapping Disadvantages: decreases respiratory movement (elderly) force broken ends inwards (if applied duringexpiration) Strapping should include two ribs above and below the affected area and should cross midline Elastic corset can be used Local strapping
    21. 21. Surgical treatment• Previously
    22. 22. PENETRATING TRAUMA
    23. 23. Causes• High speed projectiles like gunshot• Splinters from blasts• Stab injury
    24. 24. Consequences• Pneumothorax• Hemothorax• Trauma to the heart and great vessels• Pericardial tamponade• Oesophagial injury• Pulmonary contusion• Lung laceration• Rupture of the diaphragm
    25. 25. Consequences
    26. 26. Indications for thoracotomy1. Internal cardiac massage2. Control of haemorrhage from injury to the heart3. Control of haemorrhage from injury to the lungs/intrapleural haemorrhage4. Cardiac tamponade5. Ruptured oesophagus6. Aortic transection7. Control of massive air leak8. Traumatic diaphragmatic tear
    27. 27. • Thoracotomy can be  Emergency:-for control of life threatening bleeding  Planned:-for repair of specific injury
    28. 28. • Approaches: Left anterolateral Right anterolateral Median sternotomy
    29. 29. FLAIL CHESTDefinition: “A flail chest segment is formedwhen two or more consecutive ribs, with eachrib being fractured at two or more sites”Stove-in-chest: “Depression of a portion of thechest wall due to severe chest injury, whichcontributes to forming a flail segment.”
    30. 30. Significance• The real significance of the detection of paradoxical movement lies in the fact that the severity of trauma necessary to produce a flail segment has implications with respect to damage of underlying intrathoracic structures (Trinkle et al., 1975).
    31. 31. Pathophysiology1. Paradoxical Respiration2. Mediastinal Flutter3. Pendular Movement of air4. Associated injuries: Pulmonary Contusion!5. Hypoventilation
    32. 32. Complications• The early mortality attributable to the flail chest syndrome is due to – Massive haemothorax and Pulmonary contusion,• Whereas late mortality is largely due to – Adult respiratory distress syndrome (ARDS) and associated infection. Tsai et al., 1999
    33. 33. Adjuncts1. Vital signs2. Chest X-Ray3. ECG4. Pulse oximetry5. End-Tidal Carbon Dioxide6. Arterial Blood Gas7. Urinary output8. Urethral Catheterization9. Nasogastric tube10.Pelvic X-Ray

    35. 35. Stabilization of the flail segment by the application of a sandbag or by extensivestrapping is contraindicated in the hospital environment as this leads to restriction of thoracic wall movement Myllynen et al., 1983
