Study Notes
Objectives of Thoracic Trauma Management
- Identify and initiate treatment for life-threatening injuries during primary and secondary surveys.
- Primary survey focuses on critical conditions like airway obstruction, tension pneumothorax, and cardiac tamponade.
- Secondary survey evaluates injuries such as simple pneumothorax and traumatic diaphragmatic injury.
Overview of Thoracic Trauma
- Significant cause of mortality in trauma cases.
- Less than 10% of blunt injuries and 15-30% of penetrating injuries necessitate thoracotomy.
- Common pathophysiologic effects include hypoxia, hypercarbia, acidosis, and hypovolemia.
Primary Survey: Life-Threatening Injuries
- Airway patency must be ensured; check for stridor and ability to talk.
- Breathing assessment requires exposure of chest and neck, noting respiratory rate (12-24), cyanosis, and open pneumothorax.
- Tension pneumothorax diagnosed clinically; requires immediate decompression through the second intercostal space.
Specific Injuries and Interventions
- Open pneumothorax: Close the defect with sterile dressing and place a chest tube.
- Flail chest: Multiple rib fractures can cause hypoxia; manage with ventilation, oxygen, and analgesics.
- Massive hemothorax: Blood loss exceeding 1500ml managed by restoring blood volume and decompression; a chest tube is placed at the nipple level.
- Cardiac tamponade: Identified by Beck's triad (elevated venous pressure, low arterial pressure, muffled heart tones). Diagnosed using echocardiogram and can be temporarily managed with pericardiocentesis.
Secondary Survey: Evaluation for Injuries
- Simple pneumothorax treated with chest tube insertion; aspiration may be warranted for asymptomatic cases.
- Hemothorax requires prompt intervention with a large caliber chest tube; risk of complications if not fully evacuated.
- Pulmonary contusion: Monitor for significant hypoxia and may require intubation; vital ABG and pulse oximetry assessments.
- Tracheobronchial injuries present with hemoptysis and subcutaneous emphysema; close monitoring is crucial.
Traumatic Injuries and Diagnostics
- Blunt cardiac injury: Look for hypotension and dysrhythmias; elevated cardiac troponins indicate possible myocardial infarction.
- Traumatic aortic disruption: Sudden death risk; signs include widened mediastinum and rib fractures; diagnosed via CT.
- Treatment may involve primary repair, segment resection, or interposition graft depending on the injury severity.
Resuscitative Thoracotomy
- Presence of a qualified surgeon is essential for assessing the need for thoracotomy in the emergency department.
- Indications include evacuation of pericardial blood, controlling intrathoracic hemorrhage, and supporting circulation via aorta clamping.
Key Considerations
- Maintain continuous monitoring of patient vitals during assessment and treatment.
- Differentiate between tension pneumothorax and massive hemothorax through physical examination and diagnostic testing.
- Ensure prompt intervention as delays can worsen patient outcomes.
