The carbon footprint of general anaesthesia in adult patients: a multicentre observational comparison of intravenous and inhalation anaesthetic strategies in 35,242 procedures
Authors' conclusion
TIVA with propofol was the most effective approach for minimising greenhouse gas emissions in anaesthesia practices.
Study context
- Population
- Adult surgical patients under GA in three French university hospitalsanaesthetics per strategy
- Participants
- 7,873 / 15,461 / 10,717
- Exposure
- Target-controlled inhalation anaesthesia (TCIA) vs Manually optimised sevoflurane vs total intravenous anaesthesia (TIVA)
- TCIAn = 7,873
- Manually optimised sevofluranen = 15,461
- TIVAn = 10,717
- Outcome
- Total greenhouse gas (GHG) emissions per hour of anaesthesia (sevoflurane, propofol and syringe consumption), from pharmacy procurement records converted to CO2e
Methodological detailsthree French university hospitals, each using one strategy
- Three French university hospitals, each using one strategy
Main finding
As reported in the abstract
Carbon footprint of principal anaesthetic drugs per hour of anaesthesia
Observational data: associations, not effects.
