Desflurane and Sevoflurane Minimal Flow Anesthesia on Recovery and Anesthetic Depth

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.
