Updated on 2 March 2022


The SAHaRA trial will clarify the role of treating anemia with Red Blood Cell (RBC) transfusion in a unique and vulnerable patient population, and determine whether that impacts on functional outcomes and mortality. It will guide best practice standards and clarify the optimal RBC transfusion strategy in patients with aSAH.


We hypothesize that in adult patients suffering from aSAH and anemia, a liberal RBC transfusion strategy as compared to a restrictive RBC transfusion strategy decreases the combined rate of death and severe disability at 12 months (using the modified Rankin Scale)

Condition Subarachnoid Hemorrhage, Aneurysmal
Treatment Liberal RBC Transfusion Strategy, Restrictive RBC Transfusion Strategy
