A closed-circuit anesthesia ventilator facilitates significant reduction in sevoflurane consumption in clinical practice

Environmental sustainability in veterinary anaesthesia

“…Newer anaesthetic machines incorporate automated electronic closed-loop technologies to accurately control end-tidal agent concentrations; conflicting results suggest 15% increases (Wetz et al 2017) or 32% and 44% reductions in agent consumption ( € Ozelsel et al 2015) and GHG emissions (Tay et al 2013), respectively, the variation being mainly due to the difference in initial FGF over the first 15 minutes of anaesthesia used by the electronic algorithms to achieve desired inspired oxygen concentrations. Of interest, Tay et al (2013) found no increase in the cost of CO 2 absorbents, although larger (and therefore more efficient) canisters were used in the electronic closed-loop group where lower flows were used.…”

Re-defining the 3R’s (reduce, refine, and replace) of sustainability to minimize the environmental impact of inhalational anesthetic agents

“…By reducing the FGF and hence the usage of anesthetic gases, the environmental burden is lessened and significant simultaneous cost savings are achieved. 12 The topic of compound A and recommended higher FGF rates when using sevoflurane will not be explored in detail. Sevoflurane has been and is used daily worldwide in all flow ranges with no report of human morbidity, and most countries abandoned strict flow recommendations in the 1990s.…”

“…Ce qui est utilisé et la façon dont c'est utilisé ont finalement une grande répercussion sur le fardeau créé pour l'environnement, comme l'a montré un rapport récent comparant l'impact des GES créés par un hôpital canadien, un hôpital américain et un hôpital britannique. 8 Dans ce rapport, le desflurane n'était pas utilisé par l'hôpital 12 La problématique du Composé A et des DGF plus élevés recommandés avec l'utilisation du sévoflurane ne seront pas explorés en détail. Le sévoflurane a été et est utilisé quotidiennement dans le monde entier à tous les débits et sans signalement de morbidité pour l'homme; la majorité des pays ont abandonné les recommandations de débits dans les années 1990.…”

Association Between Anesthesia Provider Education and Carbon Footprint Related to the Use of Inhaled Halogenated Anesthetics

“…5 Several practice changes have been proposed for reducing greenhouse gas emissions in operating rooms, such as reducing waste from unnecessary medical devices, 6 choosing thoughtfully anesthetic drugs while taking into account their ecological impact, 7,8 reducing waste of drugs like propofol, 9 and reducing fresh gas flows to 0.5 L.min −1 , whenever possible. [10][11][12][13][14] In particular, optimizing the choice of inhaled anesthetics could lead to a substantial decrease in the carbon footprint related to anesthesia, as halogenated anesthetics can represent up to 50% of operating room total greenhouse gas emissions, 15 mainly due to desflurane. 8,16 In a recent study, as part of a continuous education program, anesthesia provider education and vaporizer labeling improved the practice of inhaled anesthetics.…”
