To observe the efficacy of acupoint pressure therapy on relieving labor pain in primiparas.One hundred and twenty primiparas were randomized into an observation group (60 cases) and a control group (60 cases). In the observation group, Hegu (LI 4), Sanyinjiao (SP 6), Taichong (LR 3), Neiguan (PC 6), Ciliao (BL 32) and Zhongliao (BL 33) on bilateral sides were selected. The acupoint pressure therapy was applied when the uterine orifice was dilated to 2 to 3 cm. In the control group, the acupoint pressure therapy was not used. Separately, when the orifice was dilated as 2 to 3 cm, 5 to 6 cm, 7 to 8 cm and 9 to 10 cm, the pain response grade was assessed (including physician's analgesia score and patient's self-evaluation score of analge-sia). The in labor pain was observed and compared in the puerperas between the two groups. The time of the first, second and third stages of labor, the time of total stage of labor as well as the cesarean section rate were compared in the puerperas between the two groups.(1) Analgesic effect:when the uterine orifice was dilated as 2 to 3 cm, 5 to 6 cm, 7 to 8 cm and 9 to 10 cm, the self-evaluation scores of analgesia in the puerperas of the observation group at each time point were all apparently lower than those in the control groups (allAcupoint pressure therapy has definite efficacy on relieving labor pain. It shortens the stages of labor and cesarean section rate.
