Xenon Compared to Sevoflurane and Total Intravenous Anaesthesia for Coronary Artery Bypass Graft Surgery

December 18, 2015 updated by: Air Liquide Santé International

Efficacy and Safety of Xenon Anaesthesia Compared to Sevoflurane Anaesthesia and Total Intravenous Anaesthesia for On-pump Coronary Artery Bypass Graft Surgery: a Randomised, Three-arm, Single-blind, International Study

Xenon is a gaseous anaesthetic agent registered in several European countries. It has been administered safely during cardiac surgery in pilot studies. In animal studies, xenon decreases the size of experimental myocardial infarction.

This 3-arm study will compare xenon, sevoflurane and a propofol-based total intravenous anaesthesia for maintenance of anaesthesia during coronary artery bypass graft surgery conducted with extra-corporeal circulation. Xenon and sevoflurane will be administered before and after extracorporeal circulation. Propofol will be administered during extracorporeal circulation in the three groups of patients.

The study will compare the postoperative myocardial damage observed 24 hours after surgery from blood levels of troponin I, a largely accepted biomarker of myocardial necrosis. The main hypothesis is that the myocardial damage observed after xenon administration will not be superior to the damage observed after sevoflurane administration (non-inferiority). The second hypothesis is that the myocardial damage observed after xenon administration will be inferior to the damage observed after total intravenous anaesthesia.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
