Effect of Intra-arterial Nimodipine on Cerebral Oxygen Saturation and Systemic Hemodynamic Indices in Patients With Cerebral Vasospasm: A Prospective Cohort Study

Background: Intra-arterial nimodipine (IaN) is used in the management of cerebral vasospasm after aneurysmal subarachnoid hemorrhage (aSAH). The impact of IaN therapy on regional cerebral oxygen saturation (rScO2) assessed by near infra-red spectroscopy, and dynamic cardiac indices, is currently unknown. This study assessed the effect of IaN on rScO2 and systemic hemodynamic indices during IaN therapy for cerebral vasospasm after aSAH. Methods: This prospective cohort study was conducted in 20 patients over sixteen month period after ethics committee approval and informed consent. Patients with angiographic evidence of vasospasm received IaN 3mg over 30 minutes in the spastic vessels. Data regarding rScO2 heart rate (HR), mean blood pressure (MBP) cardiac index (CI), stroke volume index (SVI), stroke volume variation (SVV), and total peripheral resistance index (TPRI) were collected during IaN treatment. The primary outcome measure was change in rScO2 after IaN therapy. Results: There was no significant change from baseline in ipsilateral and contralateral rScO2 after IaN administration (mean difference [MD], 0.2; 95% confidence interval [CI], −2.1 to 1.6; P=0.804, and 1.3; −1.1 to 3.8; P=0.276, respectively). There was a significant decrease in MBP and TPRI (MD, −12.4; 95% CI, −6.6 to −18.2; P
