Assessing the carbon footprint of inhalation anaesthesia, total intravenous anaesthesia, and spinal anaesthesia for a single surgical procedure: a prospective observational study

Br J AnaesthPublished Prospective observational study

Authors' conclusion

Spinal anaesthesia demonstrated the lowest carbon footprint. TIVA represented the lowest-carbon option for general anaesthesia techniques, whereas inhalation anaesthesia yielded the highest CO2e emissions despite low-flow delivery.

Study context

Population
Consecutive patients undergoing operative hysteroscopy in a French university hospital
Participants
123 patients
Exposure
Inhalation anaesthesia vs TIVA vs spinal anaesthesia
  • Inhalation anaesthesian = 72
  • TIVAn = 22
  • Spinal anaesthesian = 29
Outcome
Total carbon emissions (kgCO2e; gases, drugs, medical devices, electricity) per case
Methodological detailsGHG-focused life cycle assessment, single-centre, consecutive patients
  • GHG-focused life cycle assessment
  • Single-centre
  • Consecutive patients

Main finding

As reported in the abstract

Total carbon emissions

P < 0.001

Observational data: associations, not effects.

Further findings

Main contributors to emissions
