Objective To observe the effect of acupuncture analgesia on delivery and observe the result of analgesia in mother and infant.Methods Totally 324 primiparae were randomized into four groups:Electro-acupuncture group

82 cases

transcutaneous electrical nerve stimulation（TENS）group

82 cases

control group

81 cases

and spinal-epidural analgesia group

79 cases.The VAS scores of pain

degree of satisfaction of analgesia

outcome of delivery and changes of endorphin concentration were observed during the delivery and after.Results Compared with the TENS group and control group

viewing from the VAS scores of 30

1

20 minutes after analgesia

the effect in the electro-acupuncture group was better

but not as good as that in the spinal-epidural analgesia group

the difference was significant（P

<

0.05）.Conclusion The analgesic effect of electro-acupuncture is good with an improvement in satisfaction.The optimal analgesic effect is in the duration of 30～60 minutes with analgesia given.There is no negative influence of electro-acupuncture analgesia on birth process

mode of delivery

and result of delivery for mother and infant.It is an effective method of analgesia.
