Emergency Conversion to General Anesthesia Is a Tolerable Risk in Patients Undergoing Mechanical Thrombectomy

Adjusted odds ratio estimates with 95% confidence intervals comparing patients after emergency conversion with those who received local anesthesia, conscious sedation, and primary general anesthesia for successful reperfusion and functional independence. Successful reperfusion is TICI 2b/3 on the final angiogram, P = .002, for global differences across all groups (likelihood-ratio χ² test). Functional independence was mRS at 90 days ≤ 2, P = .12, for global differences across all groups (likelihood-ratio χ² test). Results are derived from logistic regression models, adjusted for confounders (age, sex, admission NIHSS, prestroke mRS >1, ASPECTS on admission imaging, comorbidities, application of IV thrombolysis, location of vessel occlusion and, additionally, TICI 2b/3 and occurrence of a drop of MAP in the analysis of functional independence) and based on 238 complete observations.
