AB Introduction Treatment of acute stroke has drastically changed in the last 10 years. Endovascular therapy is now the standard of care for patients with a stroke caused by a large vessel occlusion in the anterior circulation. The impact of the type of anaesthesia (general anaesthesia or conscious sedation) during endovascular therapy on the outcome of the patients is still a matter of debate. Previous studies are mostly retrospective and/or focused on the early postprocedure outcome and/or without blood pressure goals and/or single-centre small size studies. We therefore designed a multicentre study hypothesising that conscious sedation is associated with a better functional outcome 3 months after endovascular therapy for the treatment of stroke compared with general anaesthesia.Methods/analysis The General Anesthesia vs Sedation for Stroke (GASS) Trial is a randomised, parallel, single-blind, multicentre study of 350 patients undergoing endovascular therapy for the treatment of stroke. Patients will be randomly allocated to receive either a general anaesthesia or a conscious sedation. The primary outcome measure is the modified Rankin score assessed 3 months after the treatment. Data will be analysed on the intention-to-treat principle.Ethics/dissemination The GASS Trial has been approved by an independent ethics committee for all study centres. Participant recruitment begins in September 2016. Results will be published in international peer-reviewed medical journals.Trial registration number NCT02822144.
