ALB and brain edema: Human albumin is thought to have neuroprotective properties likely related to its antioxidant and antiinflammatory properties.93, 94 It has been shown to increase serum oncotic pressure and reduce cerebral edema, increase neuronal survival, and maintain blood‐brain barrier integrity.95, 96 The Albumin in Subarachnoid Hemorrhage (ALISAH) pilot study included 47 patients and identified that 1.25 g/kg/d of albumin is safe in patients with aSAH and may be associated with positive outcomes.93 There were no major complications.
