A 54-year-old woman with a long-standing history of severe alcohol use disorder is brought to the emergency department by emergency medical services after vomiting large amounts of bright red blood at home. On arrival, she is lethargic and confused. Her blood pressure is 82/50 mm Hg, and her pulse is 128/min. Physical examination reveals marked scleral icterus, multiple spider angiomas on the chest, and a visibly distended abdomen with shifting dullness. The emergency physician suspects acute variceal hemorrhage as the cause of her instability. Arrange the following management steps in the most appropriate chronological sequence for this patient.
- 1Establish two large-bore intravenous catheters and initiate crystalloid volume resuscitation
- 2Administer intravenous octreotide and prophylactic ceftriaxone
- 3Perform urgent esophagogastroduodenoscopy (EGD) for variceal ligation
- 4Evaluate for transjugular intrahepatic portosystemic shunt (TIPS) placement
Cevap
The correct chronological sequence is: 1) Establish large-bore IV access and fluid resuscitation, 2) Administer IV octreotide and prophylactic antibiotics, 3) Perform urgent EGD for variceal ligation, and 4) Evaluate for TIPS placement if the bleeding is refractory.
The algorithmic approach to suspected variceal hemorrhage prioritizes patient survival through physiological stabilization before mechanical intervention. Establishing large-bore intravenous access and administering fluids addresses the immediate, life-threatening hypovolemic shock. Vasoactive agents (octreotide) and prophylactic antibiotics (ceftriaxone) are the next most rapid and effective means to lower portal pressure and prevent infection-related mortality, respectively, and can be administered simultaneously while preparing the endoscopy suite. Endoscopy is the definitive primary treatment (via band ligation) but requires a stabilized patient. Finally, TIPS is a highly invasive salvage procedure utilized only when the aforementioned primary therapies fail to control the bleeding.

The management of acute variceal hemorrhage requires a strict stepwise algorithm: 1) hemodynamic stabilization, 2) pharmacotherapy with vasoactive agents and prophylactic antibiotics, 3) endoscopic intervention, and 4) salvage therapy with TIPS only for refractory cases.
