Objective:
To observe the effect of electroacupuncture on postpartum uterine contraction pain and uterine involution.
Methods:
A total of 80 patients with postpartum uterine contraction pain were randomly divided into an observation group and a control group, 40 cases in each group. The observation group was treated with electroacupuncture at Dahe (KI 12), Zhongzhu (KI 15), Hegu (LI 4), Xuehai (SP 10), etc. for 30 min, once a day, 3 days were as one course, and 2 courses with 1-day interval were required. The control group was treated with oral Xinshenghua tablet, 4 tablets each time, 3 times a day for 7 days. Before treatment, 24, 48, 72 h into treatment and after treatment, the visual analogue scale (VAS) score was observed; the maximum anteroposterior diameter of uterine hemorrhage, the area of hemorrhage, the space between uterus fundus and umbilical cord, and the summation of three diameters of uterus before and after treatment were compared, and the time of postpartum uterine contraction pain disappeared was recorded in the two groups.
Results:
Compared before treatment, the VAS scores of 24, 48, 72 h into treatment and after treatment were decreased in both groups (P<0.05), and those in the observation group were lower than the control group (P<0.05). Compared before treatment, the maximum anteroposterior diameter of uterine hemorrhage, the area of hemorrhage and the summation of three diameters of uterus after treatment were decreased (P<0.05), the space between uterus fundus and umbilical cord was increased in both groups (P<0.05), and those in the observation group were superior to the control group (P<0.05). The number of days required to treat the uterine contraction pain in the observation group was shorter than the control group (P<0.05).
Conclusion:
Electroacupuncture can effectively relieve postpartum uterine contraction pain, accelerate the discharge of residual uterine hemorrhage in the uterine cavity, and promote uterine involution.
