Zorluk: OrtaTrauma and Burns

An unrestrained driver is ejected from his vehicle during a rollover collision and airlifted to the regional trauma center. Upon arrival, the patient is unresponsive. His airway is rapidly secured via endotracheal intubation. Initial vital signs reveal a heart rate of 138/min and a blood pressure of 72/40 mmHg. Breath sounds are clear and equal bilaterally. The abdomen is grossly distended and rigid to palpation. Anteroposterior compression of the pelvis reveals no mechanical instability. Despite the rapid infusion of 1 L of warmed crystalloid and 1 unit of uncrossmatched packed red blood cells, his blood pressure remains critically low at 76/42 mmHg. A focused assessment with sonography for trauma (FAST) examination demonstrates a significant amount of free fluid in both the splenorenal and hepatorenal spaces. Which of the following is the most appropriate next step in the management of this patient?

  1. Urgent exploratory laparotomyCevap
  2. B
    Computed tomography of the abdomen and pelvis
  3. C
    Diagnostic peritoneal lavage
  4. D
    Pelvic angiography with embolization
  5. E
    Observation with serial focused ultrasound examinations

Cevap

Urgent exploratory laparotomy
The correct intervention is urgent exploratory laparotomy. The algorithm for blunt abdominal trauma dictates that patients who are hemodynamically unstable (e.g., persistent hypotension despite intravenous fluid and blood product resuscitation) with a positive FAST examination have massive intra-abdominal hemorrhage. These patients must be taken immediately to the operating room for laparotomy to identify and stop the bleeding. Any delay for further imaging increases mortality.

Adım Adım Çözüm

1
Assess the patient's hemodynamic status following initial resuscitation.
The patient remains persistently hypotensive (BP 76/42 mmHg) and tachycardic despite receiving intravenous fluids and uncrossmatched blood.
Determining hemodynamic stability is the critical branch point in the Advanced Trauma Life Support (ATLS) algorithm for blunt abdominal trauma.
2
Evaluate the source of hemorrhage using primary survey adjuncts.
The FAST examination is positive for free fluid in multiple abdominal spaces (splenorenal and hepatorenal).
A positive FAST in the context of blunt trauma identifies the peritoneal cavity as the source of massive hemorrhage.
3
Determine the definitive management based on stability and FAST results.
The correct management is to bypass further diagnostic imaging and proceed directly to the operating room.
A hemodynamically unstable patient with a positive FAST requires immediate exploratory laparotomy to surgically control the bleeding.
