Zorluk: KolayTrauma and Burns

A 34-year-old man is brought to the emergency department 20 minutes after a high-speed motor vehicle collision. He was the restrained driver of a vehicle that struck a concrete barrier. On arrival, the patient is confused and diaphoretic. His temperature is 36.5°C (97.7°F), blood pressure is 78/45 mm Hg, pulse is 135/min, and respirations are 24/min. Pulse oximetry shows 97% on room air. The airway is patent, and breath sounds are equal bilaterally. A focused assessment with sonography for trauma (FAST) reveals a large amount of free fluid in the hepatorenal recess (Morison pouch) and splenorenal recess. Which of the following is the most appropriate next step in management?

  1. Immediate exploratory laparotomyCevap
  2. B
    Computed tomography of the abdomen and pelvis
  3. C
    Continued observation with serial FAST examinations
  4. D
    Placement of a right-sided chest tube
  5. E
    Pelvic radiography

Cevap

Immediate exploratory laparotomy
Immediate exploratory laparotomy is the correct next step. This patient has sustained blunt trauma and is presenting in hemorrhagic shock (hypotension, tachycardia, altered mental status). In the Advanced Trauma Life Support (ATLS) algorithm, hemodynamically unstable patients with blunt abdominal trauma who have a positive FAST exam (indicating intra-abdominal hemorrhage) must be taken directly to the operating room for an exploratory laparotomy. The goal is to rapidly identify and control the source of bleeding (e.g., splenic or hepatic laceration) before irreversible shock or death occurs.

Adım Adım Çözüm

1
Assess the patient's hemodynamic status.
The patient has a blood pressure of 78/45 mm Hg and a heart rate of 135/min, indicating Class III or IV hemorrhagic shock (hemodynamic instability).
Hemodynamic status determines whether a trauma patient can safely undergo time-consuming imaging like a CT scan.
2
Evaluate the results of the primary survey and adjuncts (FAST exam).
The airway is intact, breathing is normal, but the FAST exam shows free fluid (blood) in the abdomen.
The primary survey identifies the most immediate life threats. A positive FAST in the setting of shock confirms intra-abdominal hemorrhage.
3
Determine the definitive next step for hemorrhage control.
The patient requires immediate transfer to the operating room.
An unstable patient with a confirmed intra-abdominal bleed must undergo an emergent exploratory laparotomy to stop the bleeding.
