Study Notes
Chest Injuries Overview
- Diaphragm can rise to the nipple line when a person is supine at the end of exhalation.
- Compression of the aorta and vena cava is the likely cause of deterioration in a stable patient with a pneumothorax.
- Common signs of chest injuries include respiratory distress and tachycardia; hematemesis is not typical.
- Lungs do not reside within the mediastinum, which contains structures like the heart and great vessels.
Management of Chest Wounds
- If a sealed open chest wound leads to increased respiratory distress, partially removing the dressing is necessary.
- Tension pneumothorax requires urgent intervention by inserting a needle into the pleural space.
- Pleural fluid is found between the visceral and parietal pleurae, allowing for smooth lung movement.
Respiratory Mechanics
- Thoracic cavity is separated from the abdominal cavity by the diaphragm.
- Positive-pressure ventilation can exacerbate pneumothorax injuries.
- Increased respiratory rate is needed if tidal volume decreases to maintain minute volume.
Injury Mechanisms and Symptoms
- Blunt chest trauma can lead to immediate death from traumatic aortic rupture.
- Phrenic nerves control the diaphragm, originating from spinal cord segments C3, C4, and C5.
- Patients presenting with profound cyanosis post-chest injury require immediate ventilation and oxygenation.
Specific Conditions and Signs
- Paradoxical movement in blunt chest trauma indicates a need for chest wall stabilization.
- Flail chest involves a segment of the chest wall that is detached and typically results from rib fractures.
- Myocardial contusion indicated by a rapid, irregular pulse after blunt chest trauma.
Pneumothorax and Tamponade
- Simple pneumothorax is common with blunt trauma; open pneumothorax occurs when air enters the pleural space from the outside.
- Cardiac tamponade manifests with engorged jugular veins and could develop after penetrating chest trauma.
Pediatric Considerations
- Children may be "belly breathers" due to underdeveloped intercostal muscles.
Key Assessment Indicators
- Clear and equal breath sounds are a normal finding and not indicative of injury.
- A rapid assessment for life-threatening injuries is crucial during the primary assessment.
- Pulmonary contusion suspected with a flail segment and respiratory distress despite equal breath sounds.
Additional Assessment Findings
- A patient with a history of blunt trauma showing distended neck veins, diminished breath sounds, and bruising suggests severe hemopneumothorax.
- A spinal cord injury at the C7 level primarily results in intercostal muscle paralysis without affecting diaphragm function.
Summary of Signs
- Tachypnea is a common presentation in patients with chest injuries.
- Hemoptysis, defined as coughing up blood, can occur due to various chest injuries or lung involvement.
