Introduction: Currently, new volatile anaesthetics such as sevoflurane and desflurane are in widespread clinical use for maintenance of general anesthesia. The advantage of these anaesthetics is their low blood solubility, which accounts for its extremely rapid onset of action and recovery from general anesthesia. Since 2001, several randomized controlled trials (RCT) have been carried out to assess the efficiency and safety of desflurane and sevoflurane anesthesia in patients. As each type of anesthesia has some advantages and/or disadvantages, and the conclusions have not been completely consistent. AIM: Aim of present study is comparison of maintenance and emergence characteristics after desflurane or sevoflurane in outpatient anesthesia.
