Early intervention with nimodipine in subarachnoid haemorrhage.

Abstract

Seventy-five consecutive patients with subarachnoid haemorrhage (SAH) were entered into a randomized, double-blind, placebo-controlled trial prior to angiography in order to determine the effect of early intervention with nimodipine on blood pressure (BP), cerebral blood flow (CBF), and clinical outcome. Of these patients, 50 fulfilled the criteria for the final analysis (i.e. SAH due to cerebral aneurysm and receiving 21 days of treatment). There was no difference between the BP recordings of the two treatment groups, but mean CBF decreased slightly in the nimodipine group over the 21-day treatment period. At three months, one patient on nimodipine and six patients receiving placebo had died (P = 0.049, Fisher's exact test), but no significant difference was observed between the two groups, when the 'intent to treat' group of 75 patients was considered. We conclude that nimodipine does not increase CBF or alter BP following SAH, but an improved clinical outcome is evident at three months for patients with SAH due to cerebral aneurysm who had been treated with nimodipine. There were no side-effects due to nimodipine.
