Zorluk: KolaySurgical and Procedural Interventions

A 65-year-old man is urgently evaluated by the rapid response team due to sudden-onset hypotension and altered mental status. Two days ago, he underwent an open right hemicolectomy for colon adenocarcinoma. Earlier this morning, he developed acute dyspnea; a computed tomography pulmonary angiogram confirmed a segmental pulmonary embolism, and a therapeutic continuous intravenous heparin infusion was initiated. He now appears lethargic, pale, and diaphoretic. His temperature is 37.0°C (98.6°F), blood pressure is 76/45 mm Hg, pulse is 134/min, and respirations are 24/min. Physical examination reveals a newly distended, firm, and diffusely tender abdomen. The surgical wound is intact with no external bleeding. Laboratory testing shows a hemoglobin level of 6.2 g/dL, representing a significant drop from 11.4 g/dL drawn 8 hours prior. Which of the following is the most appropriate next step in the management of this patient?

  1. Discontinue the heparin infusion, initiate volume resuscitation, and prepare for an emergent exploratory laparotomyCevap
  2. B
    Administer intravenous alteplase to treat presumed massive pulmonary embolism
  3. C
    Transfer the patient to the radiology suite for a computed tomography scan of the abdomen and pelvis
  4. D
    Perform a bedside transthoracic echocardiogram to evaluate for acute right ventricular failure
  5. E
    Administer a platelet transfusion to promote hemostasis while continuing medical therapy for the pulmonary embolism

Cevap

The most appropriate next step is to discontinue the heparin infusion, initiate volume resuscitation, and prepare for an emergent exploratory laparotomy.
The correct answer correctly identifies that the patient has developed life-threatening intra-abdominal hemorrhage as a complication of his recent surgery and subsequent heparin therapy. The definitive management for an unstable patient with active intra-abdominal bleeding is emergent surgical exploration to achieve mechanical hemostasis. This must be accompanied by immediate discontinuation of the anticoagulant and aggressive volume resuscitation with blood products.

Adım Adım Çözüm

1
Analyze the patient's acute decompensation.
The patient has new-onset hypotension, tachycardia, a distended abdomen, and an acute drop in hemoglobin from 11.4 g/dL to 6.2 g/dL.
Identifying the mechanism of shock is critical. The combination of findings indicates massive intra-abdominal hemorrhage, likely exacerbated by the recent initiation of a heparin infusion for his pulmonary embolism.
2
Determine the priority of interventions.
The active hemorrhage takes precedence over the treatment of the segmental pulmonary embolism.
Hemorrhagic shock is immediately life-threatening and must be addressed by stopping the offending anticoagulant and achieving mechanical hemostasis.
3
Select the definitive management strategy.
Discontinue heparin, begin massive transfusion, and proceed to emergent exploratory laparotomy.
Because the patient is hemodynamically unstable with a clear surgical source of bleeding (recent hemicolectomy), he requires emergent surgical exploration rather than diagnostic imaging.

Anahtar Kavram

Hemodynamically unstable postoperative patients with signs of active intra-abdominal hemorrhage require immediate discontinuation of any anticoagulants, aggressive volume resuscitation, and emergent surgical exploration.
