Objective: To explore the effect of intramuscular injection of midazolam before intravertebral anesthesia on sedation luring operation and amnesia after operation. Methods: Selected 180 ASA cases at 1~2 stage with lower extremity surgery under combined spinal and epidural anaesthesia, and randomly divided them into midazolam group and phenobarbital sodium group. Gave patients in midazolam group intramuscular injection of midazolam at 0.1mg/kg 10 min earlier before operation, while gave patients in phenobarbital sodium group 0.1 g phenobarbital sodium 30 mm earlier.
