During the latent phase in labor, several analgesia meth-ods: acupuncture analgesia, analgesics, magnetotherapy and auricular acupressure, TENS combinedwith dihydroetorphine were used respectively. While the intrauterine pressure and the peripheral con-tent of β-EP were measured during labor, the experiments of SEPS were also performed on healthyadults to demonstrate the analgesia efficacy of those analgesia methods.The combination of drugs with acupuncture is an excellent method for painless labor without anycomplications and all the mothers and babies are safety. The effectiveness is 97. 5%. The resultsdemonstrate that the mechanism of analgesia efficacy should be regulated the incoordinate uterine ac-tion and improve the hypertonic status of uterus, but also can decrease the pain threshold and elevatethe tolerance of uterine contractions during labor.更多还原
