STUDY OBJECTIVE: Vasopressin may be administered to treat vasospasm follow aneurysmal subarachnoid hemorrhage (aSAH). Few data support this practice, and it has recently been associated with clinically significant hyponatremia. The objectives of this study were to describe five cases of suspected vasopressin-induced hyponatremia after aSAH and to review the literature on this adverse effect. DESIGN: Single-center, observational case series of intensive care unit (ICU) patients SETTINGS: Ten-bed neurological intensive care unit at Maine Medical Center in Portland, Maine PATIENTS: Convenience sample of patients with aSAH treated with a vasopressin for symptomatic, radiologically-confirmed vasospasm MEASUREMENTS AND MAIN RESULTS: A total of five patients were included in the case series with a median age of 57 (51, 65) years and all were female. The median Glasgow coma scale score was 15 (11, 15) on admission and the Hunt and Hess scale score was 3, (3, 4). All patients were treated with endovascular coiling of their aneurysm. Vasopressin was administered to treat symptomatic, radiographically-confirmed vasospasm on median post-bleed day (PBD) 10 (10, 15) at a fixed-dose of 0.03 units/min. Serum sodium at baseline was 140 (140, 144) mEq/L and decreased to 129 (126, 129) mEq/L within 26 (17, 83) hours of vasopressin initiation for a median change of −16 (−10, −16) mEq/L. Serum sodium returned to baseline within 18 (14, 22) hours of stopping the infusion. CONCLUSIONS: Vasopressin administration to treat vasospasm after aSAH may be associated with clinically significant hyponatremia within 24 hours of starting the infusion. Hyponatremia appears to resolve within 24 hours of stopping the vasopressin infusion. Additional study in a larger sample size is needed to determine if a causal relationship exists.
