This study aims to compare the use of low fresh gas flow (1 L/min) desflurane anesthesia with minimum fresh gas flow (0.5 L/min) desflurane anesthesia in patients undergoing robotic-assisted abdominal surgery. The comparison will be based on hemodynamic and respiratory parameters. The secondary aim of our study is to compare the two different fresh gas flow methods in terms of inhalation agent consumption and soda lime consumption.
