The science behind banning desflurane: A narrative review

Area of Science:

• Environmental Science
• Anesthesiology
• Public Health Policy

Background:

• Potent inhaled anesthetics, primarily halogenated hydrocarbons, contribute significantly to global warming.
• While other fluorinated hydrocarbons face restrictions, volatile anesthetics have been exempt until recent EU legislative proposals.
• The European Union is considering a ban or severe restriction on desflurane use from January 2026.

Purpose of the Study:

• To review the implications of a politically driven decision on desflurane use in anesthesia practice.
• To explore scientific arguments supporting the cessation of routine desflurane use.
• To emphasize the need for broader environmental strategies in anesthesia, including waste reduction and anesthetic capture technologies.

Main Methods:

• This is a narrative review.
• Analysis of current EU legislative proposals regarding anesthetic agents.
• Review of scientific literature on the environmental impact of desflurane and other volatile anesthetics.

Main Results:

• The EU proposal to restrict desflurane, made without stakeholder consultation, could significantly impact daily anesthesia practice.
• Potential scientific arguments exist to support the discontinuation of routine desflurane use.
• Focusing solely on desflurane bans may divert attention from other crucial environmental interventions.

Conclusions:

• The proposed ban on desflurane necessitates a re-evaluation of its routine use in anesthesia.
• Stakeholder engagement is crucial for policy decisions impacting medical practice.
• Minimizing the environmental footprint of anesthesia requires a multi-faceted approach, including technological solutions for waste anesthetic gases and reduced fresh gas flows.
