Objective To investigate the effects of acupuncture-assisted anesthesia.Methods Ninety patients undergoing elective gynecologic laparoscopy, ASAⅠ~Ⅱ, were randomly divided into 3 groups, with 30 cases in each group. Group Ⅰ received only general anesthesia, group Ⅱ received general anesthesia after 20~30 minutes of HANS and Group Ⅲ received general anesthesia after HANS. Both Hegu and Taizhong were selected for acupuncture anesthesia, with 2/100 Hz, 12~15 mA(in group Ⅱ, the strength range was 3~6mA that patient could bear) acupuncture until end of surgery. The concentration of seveflurine was adjusted to maintain AAI value at 15~25 during surgery to observe stability of hemodynamics. HR and BP were recorded before and after of induction anesthesia and at the time of tracheal intubation, the skin incision, tracheal extubation. Adverse events such as postoperative pain, restlessness, shivering, respiratory depression, nausea and vomiting were observed to evaluated the analgesia quality. The time from the end of operation to extubation and awake time were recorded;The awakness of patient in operation and satisfaction of patients after surgery were also recorded. Results The Sev-MAC value change was a significance different in all groups(P0.05). Group Ⅰ was the highest, Group Ⅲ was lower and group Ⅱ was the lowest. BP and HR was more stabile in group Ⅱ and Group Ⅲ(P0.05). The time from the end of operation to extubation and the time from the end of operation to open eye on command was the longest in Group Ⅰ was(P0.05), longer in Ⅲ and shortest in Group Ⅱ. The rate of postoperative pain and restlessness in analgesia was the higgest in Group Ⅰ(P0.05). Satisfaction of patient after surgery was higher(P0.05) in group Ⅱ and Group Ⅲ. Conclusion HANS has adjuvant action for anesthesia and analgesia, and acupuncture before general anesthesia has a better action. HANS has a stable effect on perioperative hemodynamics and significantly reduces adverse reaction related to general anesthesia. It improves recovering quality and satisfaction of patient after surgery.
