Abstract:
〈 b 〉 〈 i 〉 Background and Purpose: 〈 /i 〉 〈 /b 〉 No current consensus exists on the best anesthetic management of ischemic stroke patients undergoing mechanical thrombectomy. Both conscious sedation (CS) and general anesthesia (GA) are currently considered valid anesthetic strategies, yet patients managed under CS may require emergent conversion to GA, which has been associated with worse outcomes. The aim of this study was to analyze the conversion rate and potential risk factors for GA conversion during mechanical thrombectomy. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 Two-hundred and twenty-seven patients with consecutive acute anterior circulation ischemic stroke treated with mechanical thrombectomy and initiated under CS or local anesthesia were included in this retrospective analysis. Conversion rate to GA was calculated, while univariate and multivariate analysis were used to identify risk factors. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Twenty patients (8.8%) were switched to GA. Multivariate analysis identified procedure duration (odds ratio [OR] 1.01, 95% confidence interval [CI] 1.00–1.02, 〈 i 〉 p 〈 /i 〉 value 0.028), tandem stroke (OR 8.57, 95% CI 2.06–35.7, 〈 i 〉 p 〈 /i 〉 value 0.003), Sequential Organ Failure Assessment (SOFA) (OR 1.76, 95% CI 1.19–2.61, 〈 i 〉 p 〈 /i 〉 value 0.005), and number of pharmacological agents used (OR 5.76, 95% CI 2.49–13.3, 〈 i 〉 p 〈 /i 〉 value & #x3c;0.001) as independently associated with conversion to GA. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 In our study, tandem occlusion, longer endovascular procedures, SOFA, and number of pharmacological agents used predicted the risk of emergent conversion to GA in stroke patients undergoing endovascular treatment. Prospective studies investigating optimal CS strategies are deemed necessary.
