Non‑Variceal Upper GI Bleeding — Risk Scores, PPI Strategy, and Endoscopic Hemostasis

System: Gastroenterology • Reviewed: Sep 1, 2025 • Step 1Step 2Step 3

Synopsis:

Resuscitate and risk‑stratify (Glasgow‑Blatchford). Administer high‑dose PPI and give pre‑endoscopy erythromycin when appropriate; perform early endoscopy with hemostasis. Transfuse at Hgb <7 g/dL unless exceptions; resume antiplatelets per risk/benefit.

Key Points

  • Use the highest‑yield diagnostic test early; do not let testing delay time‑critical therapy.
  • Set objective targets (hemodynamic, neurologic, respiratory) and reassess frequently.
  • Plan definitive source control or reperfusion when indicated; document follow‑up and patient education.

Algorithm

  1. Two large‑bore IVs; resuscitate with crystalloids; NPO; correct coagulopathy.
  2. Calculate Glasgow‑Blatchford score; admit vs discharge accordingly.
  3. Start high‑dose IV PPI; give IV erythromycin 30–90 min pre‑endoscopy if heavy clot burden.
  4. Early endoscopy (within 24 h) with hemostasis for high‑risk stigmata.
  5. Transfusion threshold Hgb <7 g/dL (higher in active ischemia); reverse anticoagulation as indicated.
  6. Post‑hemostasis: continue PPI protocol; test/treat H. pylori; restart antithrombotics per cardio‑GI consensus.

Clinical Synopsis & Reasoning

Resuscitate and risk‑stratify (Glasgow‑Blatchford). Administer high‑dose PPI and give pre‑endoscopy erythromycin when appropriate; perform early endoscopy with hemostasis. Transfuse at Hgb <7 g/dL unless exceptions; resume antiplatelets per risk/benefit.


Treatment Strategy & Disposition

Stabilize ABCs. Initiate guideline‑concordant first‑line therapy with precise dosing and continuous monitoring. Escalate to advanced/procedural interventions based on explicit failure criteria. Define ICU, step‑down, and ward disposition triggers; involve specialty teams early.


Epidemiology / Risk Factors

  • Risk varies by comorbidity and precipitants; see citations for condition‑specific data.

Prognosis / Complications

  • Outcome depends on timeliness of diagnosis and definitive therapy; monitor for complications.

Patient Education / Counseling

  • Provide red‑flag education, adherence guidance, and explicit return precautions; arrange timely specialty follow‑up.
