Management of Acute Gastrointestinal Bleeding

Monitoring and Resuscitation

• Monitor blood pressure, heart rate, and diuresis every hour in patients with acute gastrointestinal bleeding, as recommended by the American Association for the Study of Liver Diseases 1
• Be vigilant for signs of rebleeding, including hematemesis, melena, hypotension, or tachycardia, as suggested by the European Society of Gastrointestinal Endoscopy 2
• Use a restrictive transfusion strategy, maintaining hemoglobin between 7-9 g/dl, as recommended by the American Association for the Study of Liver Diseases 1

Pharmacological Treatment

• Continue medication at 2 mg every 4 hours for the first 48 hours, then reduce to 1 mg every 4 hours, as recommended by the American Association for the Study of Liver Diseases 1
• Maintain a regimen of 80 mg IV bolus followed by continuous infusion of 8 mg/hour for 72 hours, as suggested by the European Society of Gastrointestinal Endoscopy 2
• High-dose omeprazole after endoscopic therapy significantly reduces rebleeding rates (5.9% vs 10.3%, p=0.03) and improves outcomes, as demonstrated by multiple high-quality studies, including those published in Gut and supported by the American College of Gastroenterology with a strength of evidence level I 3, 2
• The recommended high-dose omeprazole regimen includes:

Prevention of Rebleeding

• Consider transjugular intrahepatic portosystemic shunt (TIPS) in cases of uncontrolled variceal bleeding, as recommended by the American Association for the Study of Liver Diseases and the European Society of Gastrointestinal Endoscopy 1, 4
• Test for H. pylori infection if not already done, as H. pylori eradication significantly reduces ulcer recurrence rates, with a strength of evidence based on high-quality studies, as recommended by the American College of Gastroenterology 5
• Add appropriate eradication therapy (triple or quadruple therapy) if H. pylori positive, as suggested by the European Helicobacter Study Group 5

Infection Prevention

• Maintain antibiotic prophylaxis (ceftriaxone 1g/day or norfloxacin 400 mg/12h) in patients with cirrhosis, as recommended by the American Association for the Study of Liver Diseases 4
• Continue antibiotic prophylaxis for 5-7 days in patients with variceal bleeding, as suggested by the European Society of Gastrointestinal Endoscopy 4

Nutrition and Rehabilitation

• Initiate liquid diet 4-6 hours after endoscopy if the patient is hemodynamically stable, as suggested by the European Society of Gastrointestinal Endoscopy 2
• Feed patients with low-risk stigmata within 24 hours, as recommended by the American College of Internal Medicine 6

Specific Patient Populations

• Maintain terlipressin for 3-5 days in patients with variceal bleeding, as recommended by the American Association for the Study of Liver Diseases 1
• Use the least damaging NSAID (ibuprofen) with a PPI if NSAID therapy must be continued, as suggested by the Gut journal, and maintain PPI therapy in patients with previous ulcer bleeding requiring continued antiplatelet therapy, according to the American College of Cardiology 7, 2

Indications for Repeat Endoscopy or Surgery

• Consider repeat endoscopy in cases of significant hemodynamic instability, including a drop in blood pressure >20 mmHg, increase in heart rate >20 lpm, or significant hematemesis or melena, as suggested by the European Society of Gastrointestinal Endoscopy 2
• Consider surgery or TIPS in cases of massive uncontrolled bleeding or rebleeding despite optimal medical and endoscopic therapy, as recommended by the American Association for the Study of Liver Diseases 1
• Perform follow-up endoscopy after approximately 6 weeks to confirm healing and rule out malignancy in patients with gastric ulcers, as recommended by the American College of Gastroenterology and the Gut journal 7, 2

Management of Upper GI Bleeding

• Arrange urgent endoscopy within 24 hours for active UGIB requiring immediate intervention, as recommended by the American College of Internal Medicine 6, 8
• Initiate proton pump inhibitor therapy early, even before endoscopy, to reduce rebleeding risk, as recommended by guidelines from Gut and the European Society of Gastrointestinal Endoscopy 3, 2
• Investigate and treat underlying causes, such as Helicobacter pylori infection, to prevent recurrence, as recommended by the American College of Gastroenterology and the American College of Physicians 7, 3, 2
