A 64-year-old retired teacher with a history of chronic hepatitis C viral infection and cirrhosis is brought to the emergency department after vomiting a large amount of bright red blood at home. Her husband reports she has been increasingly fatigued over the last week but had no prior episodes of bleeding. Upon arrival, the patient is lethargic but arousable. Vitals show a temperature of 36.8°C (98.2°F), pulse of 132/min, and blood pressure of 82/48 mm Hg. Physical examination reveals scleral icterus, palmar erythema, and a distended abdomen with a positive fluid wave. Capillary refill is delayed. Arrange the following interventions in the most appropriate chronological sequence for managing this patient's acute presentation.

  1. 1Insert two large-bore peripheral intravenous catheters and rapidly infuse crystalloid solutions
  2. 2Administer intravenous octreotide and a prophylactic broad-spectrum antibiotic such as ceftriaxone
  3. 3Perform urgent upper gastrointestinal endoscopy for variceal screening and targeted band ligation
  4. 4Evaluate for transjugular intrahepatic portosystemic shunt (TIPS) placement

Cevap

The correct sequence is: 1) Intravenous fluid resuscitation, 2) Intravenous octreotide and prophylactic antibiotics, 3) Urgent upper gastrointestinal endoscopy, and 4) Transjugular intrahepatic portosystemic shunt (TIPS) placement.
The management of acute variceal hemorrhage follows a strict protocol prioritizing physiological stabilization over definitive diagnosis. Initial management must focus on restoring intravascular volume with crystalloid fluids to prevent ischemic end-organ injury. Immediately following initial fluid resuscitation, pharmacotherapy must be initiated: octreotide causes splanchnic vasoconstriction to reduce portal inflow, while prophylactic broad-spectrum antibiotics (e.g., ceftriaxone) significantly reduce infectious complications, rebleeding, and mortality in cirrhotic patients. Once stabilized, the patient undergoes urgent upper endoscopy (typically within 12 hours) for definitive diagnosis and therapeutic band ligation. TIPS is a highly invasive procedure that can precipitate severe hepatic encephalopathy and is strictly reserved as a salvage therapy when combined medical and endoscopic management fails.

Adım Adım Çözüm

1
Assess hemodynamic status and initiate fluid resuscitation
Two large-bore intravenous lines are placed and crystalloid infusion begins to manage the hypovolemic shock.
Adequate perfusion must be restored to prevent ischemic end-organ damage before invasive diagnostics can be safely performed.
2
Initiate empiric pharmacotherapy for portal hypertension
Intravenous octreotide and prophylactic antibiotics (e.g., ceftriaxone) are administered.
Octreotide causes splanchnic vasoconstriction to reduce variceal pressure. Prophylactic antibiotics are standard of care as they significantly decrease mortality and rebleeding rates in cirrhotic patients.
3
Identify and arrest the source of bleeding endoscopically
Urgent upper endoscopy is performed to visualize the bleeding and apply endoscopic band ligation.
Endoscopy is the definitive primary modality to locate the bleeding source and achieve local hemostasis.
4
Consider rescue interventional therapy if bleeding is refractory
The patient is evaluated for a TIPS procedure.
If bleeding cannot be controlled endoscopically, a portosystemic shunt is created to rapidly decompress the portal venous system.
