OBJECTIVETo explore the best acupoint combination of acupuncture-assisted anesthesia in gynecologic laparoscopy operation.

METHODSNinety patients, with American Society of Anesthesiologists (ASA) physical status I - II, and scheduled for elective gynecologic laparoscopy operation, were randomly divided into 3 groups, 30 cases in each group. Group I received only general anesthesia, group II and group III received general anesthesia after Han's acupoint nerve stimulator (HANS) administered for 30 min, bilateral Zusanli (ST 36) and Sanyinjiao (SP 6) were selected for group II, and bilateral Hegu (LI 4) and Taichong (LR 3) were selected for group III. During operation, the concentration of Seveflurine was adjusted to maintain NTS at D1-D2. The change of ETsev value was recorded, the heart rate (HR) and blood pressure (BP) were observed, and the time from the end of operation to extubation, awake time were recorded adverse events such as restlessness, shivering, postoperative pain, nausea and vomiting, cases of respiratory depression, the analepsia quality, the time of first anus exhaust, the awaking of patient in operation and satisfactory of patients after surgery were recorded so as to evaluate the effect of acupuncture anesthesia.

RESULTSCompared with group I, the ETsev in group II was decreased 35% (P < 0.05), group ifi was decreased 25% (P < 0.05), with a significant difference between group II and group III (P < 0.05). BP and HR had more stability in group II and group III, the best in group II. As for the time from the end of operation to extubation and the time from the end of operation to open the eye on command, group I was the longest (all P < 0.05), group III was longer, group II was the shortest. The score of restlessness, postoperative pain, vomiting and in analepsia were the highest in group I (all P < 0.05), higher in group III and the lowest in group II. Consciousness score was lowest in group I (P < 0.05). As for the satisfactory of patient after operation, it was higher in group II and group IIII (both P < 0.05 ) than group I. The time of first anus exhaust in group II and group III were significantly shorter than that in group I (both P < 0.05).

CONCLUSIONHan's acupoint nerve stimulator has a certain adjuvant action for general anesthesia and analgesia and acupuncture point combination with both Zusanli (ST 36)and Sanyinjiao (SP 6) have the best effect in gynecologic laparoscopy operation. It can decrease the dosage of anaesthetic, has a stable effect on HR and BP during the surgery and has a better quality of analepsia.
