Endovascular Treatment of Acute Ischemic Stroke Under General Anesthesia: Predictors of Good Outcome

Background: The choice of anesthetic technique, general anesthesia (GA) versus Monitored Anesthesia Care, may impact the outcome of patients undergoing endovascular treatment of acute ischemic stroke (AIS). The aim of this study was to identify the factors associated with good discharge outcome in patients receiving GA for AIS. Materials and Methods: Electronic medical records of patients above 18 years old who underwent endovascular treatment of AIS under GA at a Comprehensive Stroke Center from 2010 to 2014 were reviewed. Good outcome was defined as discharge modified Rankin Score 0 to 2 and poor outcome as modified Rankin Score 3 to 6; logistic regression analysis was performed to examine the association between the clinical characteristics and the outcome. Results: In total, 88 patients (56 males), aged 63±15 years with median National Institute of Health Stroke Scale (NIHSS) score 16 (range, 4 to 38) were included. Nineteen (22%) patients had good outcome and 78 (88%) had systolic blood pressure below the guideline recommended 140 mm Hg under GA. After adjusting for age and NIHSS score, the independent predictors of good discharge outcomes were higher maximum end-tidal carbon dioxide (odds ratio [OR], 1.14; confidence interval [CI], 1.02-1.28; P=0.02) and extubation after endovascular treatment (OR, 26.31; CI, 4.80-144.12; P
