Summary

This study looked at whether using a very low flow of the anesthesia gas sevoflurane during heart surgery is safe and reduces environmental impact. 92 adults having planned heart surgery were randomly assigned to receive either ultra-low-flow or normal-flow anesthesia. Researchers measured how much gas was used, the carbon footprint, and whether patients stayed stable during surgery.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: sevoflurane
What this could lead to: If successful, this could show that using less anesthesia gas during heart surgery is safe and helps the environment by cutting waste and emissions.
What could go wrong: This is a small, completed study with 92 patients, so results may not apply to all heart surgeries. The main focus is on cost and emissions, not patient health outcomes.
