Cardiothoracic & vascular anesthesia
Carbon Footprint of Total Intravenous and Inhalation Anesthesia in the Transcatheter Aortic Valve Replacement Procedure
Authors' conclusion
The patients who received volatile anesthesia were found to have a higher CO2e per case. This difference remained after a subgroup analysis evaluating those patients only receiving sevoflurane and after accounting for the differences in the duration of anesthesia.
Study context
- Population
- Consecutive patients undergoing transcatheter aortic valve replacement, tertiary hospital in Boston, January 1, 2018 to March 31, 2022
- Participants
- 604 consecutive patients
- Exposure
- GA with inhaled agents vs deep sedation with total intravenous anesthesia (TIVA)
- Outcome
- Total CO2e per case (gases, drugs, airway devices, anesthesia machine electricity)
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
Total CO2e per case
P < 0.001
Observational data: associations, not effects.
Further findings
Contributors to CO2e, deep sedation with TIVA
- Intravenous medications
- 71.02%
- Airway management devices
- 16.58%
Total CO2e per case, sevoflurane-only patients (subgroup)
- Same trend with less variation
