OBJECTIVES: Studies suggest that a restrictive transfusion strategy is safe in burns, yet the efficacy of a restrictive transfusion policy in massive burn injury is uncertain. Our objective: compare outcomes between massive burn (≥60% total body surface area (TBSA) burn) and major (20-59% TBSA) burn using a restrictive or a liberal blood transfusion strategy. METHODS: Patients with burns ≥20% were block randomized by age and TBSA to a restrictive (transfuse hemoglobin 0.05). CONCLUSIONS: A restrictive transfusion strategy may be beneficial in massive burns in reducing ventilator days, ICU days and blood utilization, but does not decrease infection, mortality, hospital LOS or wound healing.
