Zorluk: OrtaTrauma and Burns

A 24-year-old male is brought to the emergency department by helicopter after colliding with a tree while skiing at high speed. On arrival, his blood pressure is 76/4076/40 mmHg, heart rate is 138138/min, and respiratory rate is 2626/min. The patient is confused, pale, and diaphoretic. The trachea is midline, and breath sounds are equal bilaterally without chest wall crepitus. The abdomen is distended with diffuse tenderness and involuntary guarding. The pelvis is mechanically stable to gentle anteroposterior and lateral compression. Bilateral large-bore peripheral intravenous lines are placed, and resuscitation with type O negative packed red blood cells is initiated. A bedside Focused Assessment with Sonography for Trauma (FAST) reveals a large anechoic collection in the splenorenal recess and the rectovesical pouch. Which of the following is the most appropriate next step in management?

  1. Exploratory laparotomyCevap
  2. B
    Computed tomography of the abdomen and pelvis with intravenous contrast
  3. C
    Diagnostic peritoneal lavage to confirm the predictive value of the ultrasound findings
  4. D
    Admission to the surgical intensive care unit for serial abdominal examinations
  5. E
    Defer intervention until a surrogate decision-maker can provide informed consent

Cevap

Exploratory laparotomy
The correct answer is exploratory laparotomy. This patient presents with hemorrhagic shock secondary to blunt trauma. The primary survey localizes the pathology to the abdomen, which is subsequently confirmed by a positive FAST exam showing intraperitoneal fluid. According to Advanced Trauma Life Support (ATLS) principles, the combination of hemodynamic instability and a positive FAST dictates immediate transport to the operating room for an exploratory laparotomy to identify and stop the bleeding.

Adım Adım Çözüm

1
Evaluate the patient's hemodynamic status.
The patient is in class III/IV hypovolemic shock (blood pressure 76/4076/40 mmHg, heart rate 138138/min, confusion).
Hemodynamic instability dictates the treatment algorithm in trauma, shifting focus from comprehensive diagnostics to immediate life-saving intervention.
2
Analyze primary survey findings to isolate the source of hemorrhage.
Chest exam is normal (rules out massive hemothorax or tension pneumothorax) and pelvis is stable. The abdomen is distended with guarding.
Identifying the anatomic compartment of bleeding determines the specific surgical or procedural intervention required.
3
Interpret the adjunct imaging (FAST exam).
The FAST exam is positive, demonstrating anechoic free fluid (blood) in dependent intraperitoneal spaces.
A positive FAST in the setting of blunt trauma confirms the abdomen as the source of major hemorrhage.
4
Determine the next best step based on ATLS protocols.
The patient requires an immediate exploratory laparotomy.
An unstable patient with a confirmed intra-abdominal source of bleeding requires emergent surgical exploration for hemostasis.

Hemodynamically unstable patients with blunt abdominal trauma and a positive FAST exam require emergent exploratory laparotomy.
