Using intrathecal nicardipine to treat vasospasm after aneurysmal subarachnoid hemorrhage

Official title: Trial of Treatment of Vasospasm Associated With Aneurysmal Subarachnoid Hemorrhage With Intrathecal Injection of Nicardipine: a Multi-center, Prospective, Double-blinded, Randomized Controlled Trial

Run by The Affiliated Hospital Of Guizhou Medical University · NCT06329635 · Data updated 2026-11-12

This study is testing if giving nicardipine directly into the spine can help patients with vasospasm after a brain bleed feel better compared to regular treatment.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-80 who have experienced spontaneous subarachnoid hemorrhage and have evidence of vasospasm.

Probably not a fit

Patients who do not have a confirmed diagnosis of vasospasm or are outside the age range may not benefit from this study.

What this trial studies

This clinical trial investigates the effectiveness of intrathecal nicardipine injections in patients experiencing cerebral vasospasm due to aneurysmal subarachnoid hemorrhage. The study employs a multi-center, prospective, double-blinded, randomized controlled design, where participants receive nicardipine via either extraventricular drainage or lumbar drainage. The treatment involves withdrawing cerebrospinal fluid followed by the injection of nicardipine and saline, with monitoring for clinical outcomes. The goal is to determine if this approach improves patient prognosis compared to standard care.

Why it matters

Potential benefit: If successful, this treatment could significantly improve outcomes for patients suffering from vasospasm after subarachnoid hemorrhage.

How similar studies have gone: While similar approaches have been explored, this specific method of intrathecal nicardipine administration is novel and has not been extensively tested in prior studies.
