A Pre- and Post- Coronary Artery Bypass Graft Implantation Disposed Application of Xenon (CArDiAX)
The Safety and Feasibility of Delivering Xenon to Patients Before and After Coronary Artery Bypass Graft Implantation: a Pilot Study
研究概览
详细说明
The study will be conducted by two investigator types: The study enrollment and the post-anesthesia follow-up will be performed by Investigator I who is blinded to the study treatment. Investigator II will only perform general anaesthesia for CABG surgery and will therefore necessarily be unblinded to the treatment conditions.
Patients will be randomly assigned to one of the following study groups. Group 1 (Xenon) will receive xenon for maintenance of balanced anesthesia for CABG surgery before and after extracorporal circulation. Group 2 (Sevoflurane) will receive sevoflurane for maintenance of balanced anesthesia for CABG surgery before and after extracorporal circulation. During extracorporal circulation, general anesthesia will be maintained intravenously in both groups.
