Zorluk: ZorSurgical and Procedural Interventions

A 72-year-old man is brought to the emergency department by ambulance due to the sudden onset of severe, tearing back pain and dizziness that began 30 minutes ago. His medical history is significant for hypertension, hyperlipidemia, and a 40-pack-year smoking history. Upon arrival, he appears pale, diaphoretic, and lethargic. His temperature is 36.5°C (97.7°F), blood pressure is 78/45 mm Hg, heart rate is 122/min, and respiratory rate is 22/min. Physical examination reveals a large, pulsatile mid-abdominal mass. Bedside ultrasonography demonstrates a 7.5-cm abdominal aortic aneurysm with adjacent free intra-abdominal fluid. Two large-bore peripheral intravenous lines are established. Which of the following are the most appropriate next steps in the management of this patient? (Select all that apply)

  1. Immediate transfer to the operating room for definitive repairCevap
  2. Resuscitation with uncrossmatched blood products to maintain a systolic blood pressure of 80 to 90 mm HgCevap
  3. C
    Computed tomography angiography of the abdomen and pelvis to evaluate the aneurysm anatomy
  4. D
    Intravenous administration of a short-acting beta-blocker to decrease aortic wall shear stress
  5. E
    Transfer to the intensive care unit for central venous catheter placement and hemodynamic optimization prior to surgery

Cevap

The correct management consists of immediate transfer to the operating room for definitive repair AND resuscitation with uncrossmatched blood products to maintain a systolic blood pressure of 80 to 90 mm Hg.
This patient is presenting with a ruptured abdominal aortic aneurysm (AAA) complicated by severe hemorrhagic shock. The most appropriate immediate management includes emergent transfer to the operating room for open or endovascular repair and the implementation of permissive hypotension. Permissive hypotension (targeting a systolic blood pressure of 80 to 90 mm Hg) with uncrossmatched blood products ensures adequate end-organ perfusion while minimizing the risk of worsening the hemorrhage by dislodging the fragile retroperitoneal clot. Crystalloids should be minimized to avoid dilutional coagulopathy.

Adım Adım Çözüm

1
Identify the primary diagnosis
Ruptured abdominal aortic aneurysm (AAA)
The patient presents with the classic triad of hypotension, back pain, and a pulsatile abdominal mass, which is immediately confirmed by bedside ultrasound showing a large AAA and free fluid.
2
Assess hemodynamic stability
The patient is in uncompensated hemorrhagic shock
Vital signs show marked hypotension (78/45 mm Hg) and compensatory tachycardia (122/min), alongside signs of poor end-organ perfusion (lethargy, diaphoresis).
3
Determine the appropriate intervention pathway
Emergent surgery and permissive hypotension
Unstable patients with a confirmed AAA rupture must be transported directly to the operating room. Resuscitation should utilize blood products and target a systolic BP of 80-90 mm Hg to maintain vital perfusion while preventing the dislodgement of hemostatic clots.

Anahtar Kavram

Hemodynamically unstable patients with a ruptured abdominal aortic aneurysm identified on bedside ultrasound require immediate operative repair and permissive hypotension with blood products. Advanced imaging (CT) and antihypertensives are contraindicated.
