Intrathecal nicardipine has been shown to have some efficacy for the treatment of symptomatic cerebral vasospasm in aneurysmal subarachnoid hemorrhage (aSAH). We performed a PRISMA-based systematic review of intrathecal nicardipine for the treatment of cerebral vasospasm in aneurysmal subarachnoid hemorrhage. A total of 825 articles were reviewed. After duplicates were removed and the search criteria was applied, 9 articles remained that were eligible for inclusion and analysis. 377 patients received a total of 6,596 injections of intrathecal nicardipine for aSAH-related cerebral vasospasm. The cumulative ventriculostomy-associated infection risk was 6%. Intrathecal nicardipine injections for aSAH-related cerebral vasospasm appears efficacious and safe. Administration of 4 mg of nicardipine every 12 hours was the most commonly reported dosing regimen. Intrathecal nicardipine decreases mean flow velocities on transcranial Doppler and reduces angiographic and clinical vasospasm. The infection risk appears to be in-line with studies in which rates of EVD-related infections have been reported.
