Management of Hematemesis After Initial Fluid Resuscitation

Immediate Priorities After Fluid Resuscitation

  • The American College of Gastroenterology recommends transfusing red blood cell concentrate in patients with active hematemesis and hemodynamic instability, or hemoglobin concentration <100 g/L in acute bleeding 1, 2
  • The American College of Gastroenterology recommends restrictive transfusion thresholds (hemoglobin 70-80 g/L) in stable patients 3
  • Insertion of a urinary catheter and monitoring of hourly urine output (target >30 mL/hour) is recommended 1, 4
  • Continuous monitoring of pulse and blood pressure using automated monitoring is recommended 1, 4
  • Consider central venous pressure monitoring in patients with significant cardiac disease (target CVP 5-10 cm H₂O) 1, 4
  • Administration of plasma expanders is recommended if patient remains shocked after 1-2 liters of saline, indicating ≥20% blood volume loss 1, 4

Pre-Endoscopic Medical Therapy

  • Administer intravenous proton pump inhibitor (PPI) therapy before endoscopy to potentially downstage the lesion and decrease probability of high-risk stigmata 3, 5

Endoscopy Timing

  • Endoscopy must be performed within 24 hours of presentation for all patients with upper GI bleeding, according to the American College of Radiology 5, 3, 4
  • Emergency endoscopy is indicated for patients with persistent hemorrhage and hemodynamic instability, or active bleeding requiring repeated transfusions 5
  • Endoscopy should only be performed after adequate resuscitation is achieved, as recommended by the American College of Gastroenterology 1, 4
  • Keep patient fasted until hemodynamically stable 1, 4
  • Consider endotracheal intubation before endoscopy to prevent pulmonary aspiration in severely bleeding patients 4

Risk Stratification to Guide Intensity of Care

  • Patients with severe bleeding (high-risk features) require intensive monitoring, urinary catheter, and urgent endoscopy, according to the American College of Gastroenterology 1, 2
  • Patients with mild-to-moderate bleeding (low-risk features) can be managed on general medical ward with hourly vital sign monitoring and semi-elective endoscopy on next available list 1, 2, 3

Special Considerations

  • Identify patients with significant liver disease early, as they require specific management protocols, according to the American Association for the Study of Liver Diseases 1, 4
  • Avoid using vasopressors in the acute bleeding phase, and focus on volume replacement, as recommended by the American Society of Anesthesiologists 7, 8
