Villanueva UGIB transfusion trial

Transfusion strategies for acute upper gastrointestinal bleeding

RCTGI bleed / transfusion

On this page

Overview

In acute upper GI bleeding, restrictive transfusion at Hb <7 g/dL improved survival compared with a liberal Hb <9 g/dL strategy.

Clinical takeaway

This trial supports restrictive transfusion in most UGIB patients, with caution in exsanguinating bleeding or active ischemic heart disease.

Key result

45-day mortality was 5% with restrictive vs 9% with liberal transfusion (HR 0.55).

Practice impact

Restrictive transfusion became standard in UGIB resuscitation once immediate instability is addressed.

Evidence

Study design

Single-center randomized controlled trial.

Enrollment

921

Follow-up

45 days.

Geography

Spain

Clinical question

Does restrictive transfusion improve outcomes in acute upper GI bleeding?

Population

  • Patients with severe acute upper gastrointestinal bleeding (including peptic ulcer and variceal sources).

Intervention

Restrictive transfusion: transfuse at Hb <7 g/dL, target 7-9 g/dL.

Comparator

Liberal transfusion: transfuse at Hb <9 g/dL, target 9-11 g/dL.

Primary outcome

Death from any cause within 45 days.

A restrictive transfusion threshold (Hb 7 g/dL) improved 45-day survival and reduced rebleeding compared with a liberal strategy in acute upper GI bleeding.

Hazard ratio / 0.55 / CI 95% CI 0.33-0.92 / p=0.02

Key results

  • 45-day mortality: 5% with restrictive vs 9% with liberal transfusion; HR 0.55 (95% CI 0.33-0.92; p=0.02).
  • Further bleeding: 10% vs 16% (p=0.01).
  • The survival benefit was significant in patients with cirrhosis and Child-Pugh class A or B disease.
  • Restrictive transfusion blunted the rise in portal pressure in cirrhotic patients.

Harms

  • Adverse events overall were fewer with the restrictive strategy.
  • Liberal transfusion was associated with more rebleeding and, in cirrhosis, higher portal pressures.

Clinical Use

When to cite

  • When choosing a restrictive transfusion strategy for upper GI bleeding after initial stabilization.

Practice impact

  • Restrictive transfusion became standard in UGIB resuscitation once immediate instability is addressed.

Applicability

  • Most applicable to patients with severe acute upper gastrointestinal bleeding.

Limitations

  • Single-center trial that excluded massive exsanguinating bleeding and acute coronary syndrome/stroke.
  • Clinical instability and active ischemia can override numeric thresholds.
  • Endoscopy was performed early (within 6 hours), which may not reflect all practice settings.

Common misinterpretations

  • The restrictive threshold applies after initial hemodynamic stabilization, not during brisk ongoing exsanguination.
  • Benefit was especially clear in cirrhosis, where over-transfusion raises portal pressure and provokes rebleeding.

As compared with a liberal transfusion strategy, a restrictive strategy significantly improved outcomes in patients with acute upper gastrointestinal bleeding.
