Fluid Balance and Blood Volume Measurement after Aneurysmal Subarachnoid Hemorrhage

Background Patients with aneurysmal subarachnoid hemorrhage (SAH) are at risk for circulatory volume depletion, which is a risk factor for delayed cerebral ischemia (DCI). In a prospective observational study we assessed the effectiveness of fluid administration based on regular evaluation of the fluid balance in maintaining normovolemia.
