cases of cholecystectomy were divided into A group (acupuncture combined small dose extradural anesthesia)

B group (stimulating acupoints with electrodes combined small dose extradural anesthesia) and C group (simple small dose extradural anesthesia

control group). The results showed that in A and B groups

the amounts of the first usage of 1.5% lidocaine for extradural anesthesia were reduced 38.17% and 29.27% respectively compared with that of C group. The anesthetic effect up to I grade in A

B

C groups occupied 68.00%

56.00% and 12.00% separately. The effects of A

B groups were better than that of C group

P<0.005; This indicated that acupuncture (including the acupoints stimulation with electrodes) combined extradural anesthesia may decrease the amounts of extradural use of anesthetics

improve the anesthetic effects and meet the elementary demands for abdominal operations. The anesthesia was complete with little interference on the body's physiological function and made it one choice in clinic. It should be noticed to the influence of respiratory rates

SPO 2

HR and BP after the intravenous injection of meperidine to keep the operation smooth.
