Background and Purpose - Hyponatremia is common after aneurysmal subarachnoid hemorrhage ( SAH). It is caused by natriuresis, which induces osmotic diuresis and decreases blood volume, contributing to symptomatic cerebral vasospasm ( SCV). Hypervolemic therapy to prevent SCV will not be efficient under this condition. We conducted a randomized controlled trial to assess the efficacy of hydrocortisone, which promotes sodium retention in the kidneys.Methods - Seventy-one SAH patients were randomly assigned after surgery to treatment with either a placebo ( n = 36) or 1200 mg/d of hydrocortisone ( n = 35) for 10 days and tapered thereafter. Both groups underwent hypervolemic therapy. The primary end point was the prevention of hyponatremia.Results - Hydrocortisone prevented excess sodium excretion ( P = 0.04) and urine volume ( P = 0.04). Hydrocortisone maintained the targeted serum sodium level throughout the 14 days ( P < 0.001), and achieved the management protocol with lower sodium and fluid ( P = 0.007) supplementation. Hydrocortisone kept the normal plasma osmolarity ( P < 0.001). SCV occurred in 9 patients ( 25%) in the placebo group and in 5 ( 14%) in the hydrocortisone group. No significant difference in the overall outcome was observed between the 2 groups.Conclusions - Hydrocortisone overcame excess natriuresis and prevented hyponatremia. Although there was no difference in outcome, hydrocortisone supported efficient hypervolemic therapy.
