Brief summary
Minimal flow anesthesia has economic and environmental advantages in addition to providing earlier recovery following general anesthesia. There is a paucity of data concerning the effect of minimal flow anesthesia (fresh gas flow \<0,5 l/min) on recovery parameters. The primary objective of this study is to compare the recovery parameters of desflurane and sevoflurane in minimal flow anesthesia while the secondary objective is to compare the effect of these agents on anesthetic depth using bispectral index.
Interventions
Sevoflurane will be used for the maintenance of general anesthesia which will be carried out using a fresh gas flow of less than 0,5 l/min
Desflurane will be used for the maintenance of general anesthesia which will be carried out using a fresh gas flow of less than 0,5 l/min
