Gave patients in midazolam group intramuscular injection of midazolam at 0.1 mg/kg 10 min earlier before operation, while gave patients in phenobarbital sodium group 0.1 g phenobarbital sodium 30 min earlier. With Ramsay sedation evaluation assessed mean arterial pressure and heart rate during anesthesia, before and after operation, respectively.

选择ASA1～2级择期在腰硬联合阻滞下行下肢手术的患者180例，随机分为咪唑安定组和苯巴比妥钠组，咪唑安定组患者入室后(实施麻醉前10 min)肌内注射咪唑安定0.1 mg/kg，苯巴比妥钠组患者入室前30 min肌内注射苯巴比妥钠0.1 g。

The anti-bacteria effect of the soda lime can be influenced by the chemical response between soda lime and CO2, the bacteria in the patient airway may be polluting the ventilation system of the anesthesia machine, so the hospital cross-infection was present in this repeat use of soda lime and ventilation tube. The hospital infection can be effectively prevented by using the one time ventilation tube, the virus/bacteria filter utensil and/or rechange the soda lime in the general anesthesia.
