What is the initial management for a patient presenting with variceal bleeding?

Initial Management of Variceal Bleeding

The initial management of a patient with variceal bleeding should include immediate administration of vasoactive drugs (terlipressin, somatostatin, or octreotide), volume resuscitation with a restrictive transfusion strategy, and prophylactic antibiotics, followed by urgent endoscopy within 12 hours of presentation. 1

Immediate Stabilization and Medical Management

Hemodynamic Stabilization

• Volume replacement: Promptly initiate fluid resuscitation with crystalloids and/or colloids to maintain hemodynamic stability 1
• Restrictive transfusion strategy: Transfuse red blood cells when hemoglobin falls below 7 g/dL, with a target range of 7-9 g/dL 1, 2
• Avoid starch for volume replacement 1
• Monitor coagulation parameters but avoid excessive blood product transfusion which can increase portal pressure 1

Pharmacological Management

1. Vasoactive drugs: Start immediately upon suspicion of variceal bleeding, even before endoscopy 1, 2

   • Options:
     • Terlipressin: 2 mg IV every 4 hours initially, can be reduced to 1 mg IV every 4 hours once bleeding is controlled 1
     • Somatostatin: 250 μg IV bolus followed by infusion of 250 μg/hour 1
     • Octreotide: 50 μg IV bolus followed by continuous infusion of 50 μg/hour 1
   • Duration: Continue for 3-5 days 1, 3

2. Antibiotic prophylaxis: Start immediately and continue for up to 7 days 1, 2

   • First choice: Ceftriaxone 1 g IV daily for patients with decompensated cirrhosis, those on quinolone prophylaxis, or in settings with high quinolone resistance 1
   • Alternative: Oral norfloxacin 400 mg twice daily 1

Pre-Endoscopy Preparation

• Erythromycin: Consider IV erythromycin 250 mg 30-120 minutes before endoscopy to improve visualization (check QT interval first) 1, 2
• Avoid beta-blockers and vasodilators during the acute bleeding episode 1

Endoscopic Management

Timing and Setting

• Perform endoscopy within 12 hours of presentation once hemodynamic stability is achieved 1, 2
• Setting: Intensive care unit or well-monitored setting 1

Endoscopic Intervention

• For esophageal varices: Endoscopic variceal band ligation (EVL) is the treatment of choice 1, 2
• For gastric varices:
  • GOV1 (extension along lesser curve): Treat like esophageal varices with band ligation 2
  • GOV2/IGV1 (fundal varices): Cyanoacrylate injection is preferred 2

Management of Treatment Failure

Early Rebleeding (10-15% of cases)

• TIPS (Transjugular Intrahepatic Portosystemic Shunt): Should be used as rescue therapy of choice 1, 3
• Pre-emptive TIPS: Consider within 24-72 hours for high-risk patients (Child-Pugh C with score <14 or Child-Pugh B with active bleeding) 1, 3

Temporary Measures for Uncontrolled Bleeding

• Balloon tamponade: Use only as a temporary "bridge" (maximum 24 hours) until definitive treatment 1
• Self-expanding esophageal stents: Can be used as alternative to balloon tamponade 1

Special Considerations

Medication Warnings

• Terlipressin: Monitor for respiratory failure, which occurred in 14% of patients in clinical trials 4
• Avoid terlipressin in patients with history of severe cardiovascular conditions or ischemic disease 4

Prevention of Complications

• Lactulose: Consider prophylactic use to prevent hepatic encephalopathy, which is common during bleeding episodes 1
• Monitor oxygen saturation continuously, especially when using terlipressin 4

Follow-up After Acute Management

• Schedule follow-up endoscopic band ligation at 1-4 week intervals until varices are eradicated 2
• Initiate non-selective beta-blockers (preferably carvedilol) for secondary prophylaxis once the acute bleeding episode has resolved 2

This approach to variceal bleeding management has significantly reduced mortality from 40% to 15-20% over the past two decades 3, highlighting the importance of prompt, systematic intervention following evidence-based guidelines.
