Initial Management of Hematemesis
For a patient presenting with hematemesis, immediately assess hemodynamic stability, initiate resuscitation with IV access and fluids, transfuse blood if hemoglobin <80 g/L (or higher threshold with cardiovascular disease), start intravenous proton pump inhibitor therapy, and arrange endoscopy within 24 hours 1.
Immediate Resuscitation and Stabilization
The first priority is hemodynamic assessment and resuscitation:
- Establish large-bore IV access (two lines preferred) and begin crystalloid resuscitation if signs of hypovolemia are present
- Monitor vital signs continuously - look specifically for tachycardia (>100 bpm), hypotension (SBP <100 mmHg), altered mental status, or signs of shock
- Obtain immediate laboratory studies: complete blood count, coagulation profile, type and crossmatch, metabolic panel
Blood Transfusion Strategy
Use a restrictive transfusion threshold of hemoglobin <80 g/L (8 g/dL) in patients without cardiovascular disease 1. This is a conditional recommendation based on low-quality evidence but represents current best practice.
For patients with underlying cardiovascular disease (coronary artery disease, heart failure, significant valvular disease), transfuse at a higher hemoglobin threshold 1. While the exact threshold isn't specified in the guideline, clinical practice typically uses 90-100 g/L in this population.
Pharmacologic Management
Administer intravenous proton pump inhibitors immediately 1, 2. Pre-endoscopic PPI therapy may downstage endoscopic lesions and decrease the need for intervention, though it should not delay endoscopy 1.
- If portal hypertension/varices are suspected (history of cirrhosis, stigmata of liver disease), add splanchnic vasoconstrictors (octreotide or terlipressin) and prophylactic antibiotics 2
What NOT to Do
- Do not routinely place nasogastric tubes - consider only in selected patients as findings may have prognostic value 1
- Do not use promotility agents routinely before endoscopy 1
- Do not delay endoscopy in patients on anticoagulants (warfarin or DOACs) 1
Timing of Endoscopy
Perform endoscopy within 24 hours of presentation 1, 2. This is a conditional recommendation with very low-quality evidence, but achieved 100% consensus among the international expert panel.
For patients with suspected portal hypertension/variceal bleeding, perform endoscopy within 12 hours 2. These patients have higher mortality (up to 30% versus 10% for non-variceal bleeding) and require more urgent intervention.
Risk Stratification
While resuscitating, assess risk factors that predict poor outcomes:
- High-risk features: ongoing hematemesis, hemodynamic instability despite resuscitation, hemoglobin <80 g/L, elevated BUN/creatinine ratio (suggesting significant blood loss), comorbidities (cardiovascular disease, cirrhosis, malignancy), advanced age
- Low-risk patients with stable vital signs, hemoglobin >100 g/L, no comorbidities, and no high-risk features on endoscopy may be candidates for early discharge 1
Anticoagulation Management
Do not delay endoscopy in patients taking anticoagulants (vitamin K antagonists or DOACs) 1. The risk of delaying diagnosis and treatment outweighs procedural bleeding risk. Endoscopic hemostatic therapy can be performed safely in these patients.
Common Pitfalls to Avoid
- Overtransfusion: Liberal transfusion strategies (targeting hemoglobin >100 g/L) increase mortality and rebleeding rates. Stick to the restrictive threshold unless cardiovascular disease is present
- Delaying endoscopy for "stabilization": Once initial resuscitation is underway, proceed to endoscopy within the recommended timeframe
- Assuming all hematemesis is peptic ulcer disease: Consider variceal bleeding in any patient with risk factors for liver disease, as management differs significantly
- Using epinephrine injection alone during endoscopy: This provides suboptimal efficacy and must be combined with another hemostatic method 1
