Mechanism of acupoint transcutaneous electric stimulation on analgesic anesthesia in the patients undergoing general anesthesia anorectal operation

To observe the regulatory effects of acupoint electric stimulation on the analgesic substances and the relevant indices of nerve-immunity-endocrine system in the patients undergoing general anesthesia anorectal operation.One hundred and fifty-six patients undergoing hemorrhoids and anal fistula operation were randomized into three groups, 146 cases were included in the analysis. In the No.1 group (48 cases), the conventional intravenous general anesthesia was applied. In the No.2 group (50 cases), besides the conventional intravenous general anesthesia, the acupoint transcutaneous electric stimulation was combined at Neiguan (PC 6), Shenmen (HT 7), Shangliao (BL 31) and Ciliao (BL 32). operation in the No.2 and No.3 groups were lower apparently than that in the No.1 group (P 0.05). The pain degrees in 1 h after.
