Réduction de l'impact écologique imputable aux gaz d'anesthésie au CHU de Bordeaux

Abstract : Background: volatile agents are worldwide daily used anesthesic agents. However, they are responsible for notorious greenhouse gas effect. No management program for reduction of volatile agents consumption and emission exists. The purpose of this study was to determine the effect of the implementation of a management program based on a multimodal strategy to reduce environmental impact caused by volatile agents. Methods: we performed an audit of clinical practice before and after implementation of the management program. This program was based on a three-stage strategy. Firstly, we prospectively evaluated professional practice regarding halogenated agents managements (phase I). Secondly, we implemented the protocol. And finally, we assessed professional practice again (after implementation) and compared the results with those of the first part (phase II). 350 procedures were included in Phase I and 420 in Phase II. We hypothesize! d that the management program implementation would lead to a reduction of greenhouse gas emission. The primary outcome was the reduction of mean fresh gas flow (FGF) used for maintenance of general anesthesia. Results: the implementation of the management program led to a 35% decrease in mean FGF between the two phases (1.7 ± 1.6 L/min vs 1.1 ± 0.8 L/min for Phase I and Phase II respectively, p <0.001) which represented a 51 542 kg EqCO2 reduction in green-house gas emission. Conclusion: the implementation of a management program for a well-reasoned use of volatile agents led to a significant reduction of greenhouse gas emission. This type of action should be undertaken to minimize the adverse effect of anesthesia on the environment.
