Abstract

Background Debate exists as to whether patients with acute ischemic stroke who are undergoing mechanical thrombectomy should receive general anaesthesia or conscious sedation during the procedure. Using a multihospital administrative database, we compared outcomes and complications of patients receiving mechanical thrombectomy, who were receiving general anaesthesia and conscious sedation, and studied trends in usage over time. Materials and methods Premier database patients who underwent mechanical thrombectomy from 2006 to 2013 for acute ischemic stroke were identified. Using propensity score analysis, recipients of general anaesthesia and conscious sedation underwent 1:1 matching. Outcomes including usage trends, discharge status, mortality, length of stay, haemorrhage and pneumonia were examined. Results A total of 2512 patients receiving mechanical thrombectomy were identified. 1999 (80%) received general anaesthesia and 513 (20%) received conscious sedation. Following 1:1 matching by the propensity score matching, 507 general anaesthesia and 507 conscious sedation patients were matched. Patients who received general anaesthesia during their procedure had significantly higher rates of in-hospital mortality (25% vs 12%, OR=2.37 95% CI 1.68 to 3.37, p
