Assessing Lung Dynamics and Respiratory Functions in Minimal Flow Anesthesia: A Prospective Study

Group MeFA; after reaching the MAC 1 value with 4lt/min 50% O2 - 50% air and 8% desflurane with remifentanil infusion, medium flow anesthesia was started with 2 lt/min 50% O2 - 50% air with MAC 1 concentration desflurane. The vaporizer was closed at the end of the last suture, and the flow was increased to 80% oxygen at 6 lt/min.

Group MiFA; after reaching the MAC 1 value with 4 lt/min 50% O2 - 50% air and 8% desflurane with remifentanil infusion, minimal flow anesthesia was started with 0.50 lt/min 50% O2 - 50% air with MAC 1 concentration of desflurane. The vaporizer was closed at the end of the last suture, and the flow was increased to 80% oxygen at 6 lt/min.
