Anesthesia
Conditions
Brief summary
The goal of this prospective, randomized study is to compare recovery characteristics between remimazolam anesthesia with flumazenil and desflurane anesthesia in patients undergoing closed reduction of nasal bone fracture. The main question this study aims to answer is: * Is there statistically significant difference in time from discontinuation of the anesthetic agent up to patient's response to verbal command between these two groups? Participants will receive either remimazolam or desflurane for the maintenance of general anesthesia. When the surgery ends, the anesthetic agent will be stopped. For Remimazolam group, flumazenil will be administered as an antagonist of remimazolam.
Interventions
General anesthesia was induced with 12 mg/kg/hr of intravenous remimazolam. When loss of consciousness was achieved, the infusion rate of remimazolam was reduced to 1mg/kg/hr for maintenance. At the end of surgery, 0.2 mg of flumazenil is administered.
Desflurane (1 minimum alveolar concentration (MAC) of end-tidal desflurane concentration) is used for the maintenance of general anesthesia. Induction of general anesthesia is achieved with 1-2 mg/kg of intravenous propofol bolus.
