Study Notes
Chest Injuries Overview
- Chest trauma is responsible for 25% of trauma deaths; contributes to an additional 50%.
- Majority of serious chest injuries managed with chest drainage and resuscitation; only 10-15% require surgery.
- Common causes of chest trauma include road traffic accidents (RTCs), industrial accidents, and sporting injuries.
- Major complication from chest injuries is hypoxia, linked to ventilation impairment or hypovolemia.
Injury Potential
- Structures potentially injured include heart, blood vessels, lungs, airways, soft tissue, bones, spinal cord, and nerves.
- Rib injuries may indicate underlying damage to liver, kidneys, spleen, and other abdominal organs.
- Attention to neck/spinal injuries is crucial in trauma cases.
Mechanism of Injury (MOI)
- Blunt force injuries from RTCs, falls, and sports typically have an on-scene time of less than 20 minutes.
- Penetrating trauma such as gunshot or stab wounds may have an on-scene time of minutes.
Signs and Symptoms
- Indicators of chest injury include hypoxia, dyspnea, tachypnea, abnormal respiratory patterns, bruising, swelling, and pain.
- Patients may demonstrate reduced consciousness and anxiety; assessment of time-critical situations is essential.
Types of Chest Injuries
- Rib injuries: Common and may lead to shallow breathing and inadequate ventilation; can result in blood loss.
- Fractured sternum occurs in 5% of blunt thoracic trauma cases; indicative of potential major injuries, with a high mortality rate.
- Flail chest involves multiple rib fractures causing inadequate ventilation of the underlying lung.
Pneumothorax
- Defined as air in the pleural space; can be spontaneous or trauma-induced.
- Small pneumothorax may be benign if not progressing to tension pneumothorax; symptoms vary by size.
- Tension pneumothorax is a life-threatening condition where trapped air increases thoracic pressure, leading to lung collapse and obstructive shock.
Open Pneumothorax
- Resulting from penetrating trauma, it allows air to enter the pleural cavity, creating a "sucking chest wound."
- Requires immediate medical intervention to restore normal breathing mechanics.
Haemothorax
- Presence of blood in the pleural cavity typically due to penetrating injury or blunt trauma.
- Can be time-critical, associated with hypoxia and hypovolemia, necessitating immediate treatment.
Cardiac Tamponade
- Occurs when excessive fluid in the pericardial sac compresses the heart, limiting its pump capacity.
- Often related to penetrating injuries; as little as 20-30ml of blood can induce tamponade, making it a life-threatening condition.
Assessment Protocol
- Conduct primary survey assessing Circulation, Airway, Breathing, Disability, and Exposure (C ABCDE).
- Identify catastrophic hemorrhages, airway or breathing issues, and other critical conditions demanding immediate advanced interventions.
- Prioritize chest exposure during assessment to evaluate injury extent and treatment needs.
