Trauma and Emergency Surgery
Core Concepts
Master the ABCDE approach to trauma. Understand indications for emergency thoracotomy, laparotomy, and damage control surgery. Key topics: hemorrhagic shock, tension pneumothorax, cardiac tamponade, and massive transfusion protocols. In abdominal trauma, know the indications for operative vs. nonoperative management (e.g., FAST, CT stability). For penetrating trauma, explore if peritoneal signs or hemodynamic instability. Also, understand the principles of burn management and compartment syndrome.
Traps in Questions
A frequent trap is the “stable patient with positive FAST” – they may still need laparotomy if they become unstable. Another trap is the use of CT in hemodynamically unstable patients: never. For pelvic fractures, beware of the “open book” pelvis and the need for pelvic binder. Also, know that negative FAST does not rule out retroperitoneal injury. In burn patients, calculate fluid resuscitation using the Parkland formula and remember that inhalation injury increases mortality independent of burn size.
Worked Example
A 30-year-old motorcyclist presents with hypotension, distended abdomen, and positive FAST. What is the next step? Answer: Immediate laparotomy after initiation of massive transfusion protocol. Do not delay for CT.
Rule of Thumb
In trauma, “treat the patient, not the numbers” – a systolic BP of 90 may be acceptable in a young patient but not in the elderly.
