A 28-year-old man is brought to the emergency department after a high-speed motorcycle collision. He was reportedly thrown 30 feet from his vehicle. Upon arrival, he is immobilized on a backboard with a cervical collar. His pulse is 142/min, blood pressure is 76/40 mmHg, and respiratory rate is 28/min. Pulse oximetry shows 94% on a nonrebreather mask. The patient is diaphoretic and confused. The airway is clear, and the trachea is midline. Breath sounds are equal bilaterally. A portable chest radiograph reveals a widened mediastinum, obliteration of the aortic knob, and a left apical cap. Focused assessment with sonography for trauma (FAST) demonstrates a large amount of anechoic fluid in the hepatorenal and splenorenal recesses. The pelvis is stable to anteroposterior compression, and bilateral femur radiographs show no fractures. Intravenous access is secured, and a massive transfusion protocol is initiated. Which of the following is the most appropriate next step in management?

  1. A
    Computed tomography angiography of the chest, abdomen, and pelvis
  2. Exploratory laparotomyCevap
  3. C
    Intravenous administration of esmolol
  4. D
    Left anterolateral thoracotomy
  5. E
    Thoracic endovascular aortic repair

Cevap

The most appropriate next step in management is to perform an emergent exploratory laparotomy to control the active intra-abdominal hemorrhage.
The correct answer is exploratory laparotomy. This patient is in severe hypovolemic shock following blunt trauma. The positive FAST exam localizes the primary source of active, uncontained hemorrhage to the abdomen. Although the abnormal chest radiograph findings (widened mediastinum, obliteration of the aortic knob, left apical cap) are highly suspicious for a blunt thoracic aortic injury (BTAI), most patients who survive a BTAI to reach the hospital have a contained hematoma (the adventitia remains intact). The immediate life-threatening problem is the active intra-abdominal hemorrhage. Therefore, according to Advanced Trauma Life Support (ATLS) protocols, emergent exploratory laparotomy to control the intra-abdominal bleeding takes absolute precedence. Once the abdominal hemorrhage is controlled and the patient is stabilized, further diagnostic imaging (e.g., CT angiography) and treatment for the suspected aortic injury can be safely pursued.

Adım Adım Çözüm

1
Assess the patient's hemodynamic status.
The patient is in profound Class III/IV hypovolemic shock (blood pressure 76/40 mmHg, heart rate 142/min).
Establishing hemodynamic stability dictates the entire ATLS algorithm and limits diagnostic imaging options.
2
Analyze the primary survey adjuncts to identify the source of hemorrhage.
The FAST exam is strongly positive for intra-abdominal fluid, while the chest radiograph shows signs of a contained thoracic aortic injury (widened mediastinum, obliteration of aortic knob).
Identifying the active, uncontained source of bleeding is critical for prioritizing surgical intervention.
3
Determine the immediate therapeutic priority based on competing injuries.
Exploratory laparotomy is chosen as the immediate next step.
Uncontained intra-abdominal hemorrhage causes rapid death and must be surgically controlled immediately; contained aortic injuries are definitively diagnosed and addressed only after active bleeding is stopped.
