Abstract
© The Author(s) 2018. Background: Guidelines for aneurysm subarachnoid hemorrhage (aSAH) management recommend treatment with nimodipine to all patients to reduce delayed cerebral ischemia (DCI) and poor clinical outcome. However, it did not give the most beneficial time to start therapy and route of administration. Objectives: To compare the DCI occurrence and clinical outcome among aSAH patients who received nimodipine treatment at different times. Methods: A retrospective cohort study was conducted by collecting data from medical chart reviews between August 30, 2010, and October 31, 2015, at Prasart Neurological Institute, Thailand. Patients were classified into 2 groups by time to receive nimodipine: early group and late group (<96 and >96 hours, respectively). All patients received intravenous (IV) followed by oral nimodipine to complete treatment course. Clinical outcome was graded using the Glasgow Outcome Scale at 21 days. The factors related to DCI were analyzed using multivariate logistic regression. Results: A total of 149 patients were recruited: early (n = 97) and late (n = 52). No difference in baseline characteristics between groups was observed. The occurrence of DCI was not statistically significantly different between groups (early group, 18.60%, vs late group, 20.80%; P = 0.74). The World Federation of Neurosurgical Societies IV to V was associated with DCI occurrence. The proportion of patients with good outcome, poor outcome, or death did not show any difference between groups. Conclusions and Relevance: Receiving IV nimodipine 3 to 7 days following oral therapy after bleeding can be the alternative regimen in patients who did not start nimodipine within 96 hours.
