Association of hemoglobin trend and outcomes in aneurysmal subarachnoid hemorrhage: A single center cohort study.

Background: Anemia has been linked to delayed cerebral ischemia (DCI) and worse outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). However, the association of hemoglobin (Hb) trend and outcomes is not well studied. We investigated predictors of Hb trend and its association with outcomes in patients with aSAH.
