RESUMEN
This study was done on 60 adult patients of both sexes between 18-45 years old undergoing ambulatory surgery. All of them were ASA I and II and categorized into three groups, each including 20 patients: Group I maintained on halothane, group II maintained on isoflurane and group III maintained on desflurane. Using bispectral index [BIS], all maintenance drugs were titrated to keep BIS monitor value around 40-60. The vital signs measured were heart rate and MAP with no statistically significant difference between the three groups. The modified Aldrete score showed significantly high scores for desflurane group as compared with the other two groups. As regard to the post- anesthesia discharge scoring system [PADSS] and time to home discharge, there were no statistical significant differences between all groups
