Upper Gastrointestinal Bleeding Management Guidelines

Initial Assessment and Resuscitation

The American College of Physicians recommends immediate resuscitation for patients with acute upper gastrointestinal bleeding and hemodynamic instability to restore end-organ perfusion and tissue oxygenation 1, 2
Blood transfusion is recommended for patients with a hemoglobin level <80 g/L in those without cardiovascular disease, according to the American College of Physicians 1, 2
For patients with underlying cardiovascular disease, the American College of Physicians recommends using a higher hemoglobin threshold for transfusion 1, 2
The American Gastroenterological Association suggests considering placement of a nasogastric tube in selected patients as findings may have prognostic value 1, 3

The American College of Gastroenterology recommends using the Glasgow Blatchford score to identify patients at very low risk (score ≤1) who may not require hospitalization or inpatient endoscopy 1, 2
High-risk factors include age >60 years, shock, comorbidities, active bleeding or non-bleeding visible vessel on endoscopy, according to the American Gastroenterological Association 4, 5

The American College of Gastroenterology recommends starting intravenous proton pump inhibitor therapy, which may downstage endoscopic lesions but should not delay endoscopy 1, 6
For suspected variceal bleeding in patients with cirrhosis, the American Association for the Study of Liver Diseases suggests initiating vasoactive drugs and administering antibiotic prophylaxis 2

The American Society for Gastrointestinal Endoscopy recommends performing endoscopy within 24 hours of presentation for most patients with upper gastrointestinal bleeding 1, 2
For high-risk stigmata, the American College of Gastroenterology recommends using combination endoscopic therapy (injection plus thermal coagulation or clips) 1, 3, 6

The American College of Gastroenterology recommends administering high-dose PPI therapy for 3 days for patients with high-risk stigmata who have had successful endoscopic therapy 2, 6
The American Gastroenterological Association suggests testing all patients for Helicobacter pylori and providing eradication therapy if infection is present 2, 6

The American Heart Association recommends restarting acetylsalicylic acid (ASA) as soon as cardiovascular risks outweigh gastrointestinal risks (usually within 7 days) for patients requiring cardiovascular prophylaxis 2, 6
The American College of Cardiology suggests that ASA plus PPI therapy is preferred over clopidogrel alone to reduce rebleeding 2, 6
The American College of Gastroenterology recommends PPI therapy for patients with previous ulcer bleeding who require antiplatelet or anticoagulant therapy 2, 6

Use crystalloids (normal saline or Ringer lactate) rather than colloids for initial resuscitation, as colloids offer no mortality benefit and are more expensive, according to the American College of Physicians 7
Balanced crystalloids like Ringer lactate may reduce acute kidney injury compared to normal saline, as recommended by the American College of Physicians 7
Avoid overly aggressive fluid resuscitation targeting normal blood pressure, as this may exacerbate bleeding and disrupt coagulation, as stated by the American College of Physicians 7
