Management of Upper Gastrointestinal Bleeding

Immediate Assessment and Resuscitation

The American College of Gastroenterology recommends checking vital signs immediately to determine severity and guide management, with pulse >100 bpm, systolic blood pressure <100 mmHg, or signs of shock indicating severe bleeding requiring emergency intervention 1
Hemodynamic instability despite resuscitation is a high-risk feature requiring aggressive management, with the goal of maintaining hemoglobin >7 g/dL (or >9 g/dL if massive bleeding or cardiovascular disease present) 1
The American College of Emergency Physicians suggests establishing two large-bore IV lines in the anticubital fossae and beginning aggressive fluid resuscitation with normal saline, with an initial infusion of 1-2 liters in hemodynamically compromised patients 2
If shock persists after 2 liters, add plasma expanders as this indicates ≥20% blood volume loss, and insert a urinary catheter to measure hourly urine output (target >30 ml/h indicates adequate resuscitation) 1

Coffee ground vomit results from gastric acid converting hemoglobin to hematin, creating the characteristic dark, granular appearance that indicates less active bleeding compared to bright red blood, as the blood has had time to be partially digested 1
The most common causes of upper gastrointestinal bleeding include peptic ulcer disease (35-50% of cases), Mallory-Weiss tears (15%), gastroduodenal erosions (8-15%), esophagitis (5-15%), and varices (5-10%) 3, 4
Specifically assess for cirrhosis, as variceal bleeding mortality approaches 30% versus 10% for nonvariceal sources and requires specialized management with prophylactic antibiotics and vasoactive medications 2, 4

The American Society for Gastrointestinal Endoscopy recommends performing endoscopy within 24 hours after achieving hemodynamic stability, with blood pressure and CVP ideally stable before endoscopy 1, 2
Critical pitfall: do not perform endoscopy before adequate resuscitation in unstable patients, as this increases mortality, and keep the patient fasted until hemodynamically stable 1, 2

Evaluate for non-GI conditions in hemodynamically stable patients, including acute myocardial infarction, sepsis, pulmonary emboli, small bowel obstruction, and acute renal failure, as these are frequently the primary diagnosis in stable patients with coffee ground material 1, 4
Elderly patients (>65 years) have significantly higher mortality rates and require more aggressive inpatient management, while very low-risk young patients without hemodynamic compromise, significant comorbidities, or high-risk features may be managed as outpatients after appropriate evaluation 1, 2

Monitor for rebleeding, defined as fresh hematemesis and/or melena associated with shock (pulse >100 bpm, systolic pressure <100 mmHg), CVP fall >5 mmHg, or hemoglobin reduction >20 g/L over 24 hours, and address underlying causes such as Helicobacter pylori eradication, acid suppression, and counsel regarding NSAID use 2, 3, 4
