Most of the clinical pregnant women, especially the first puerpera, refuse to accept vaginal delivery due to fear of labor pain, which makes the clinical cesarean section rate present a continuous high trend in recent years. The appearance of severe labor pain symptoms can make the frequency of uterine contraction and cervical dilation uncoordinated, make the progress of labor process appear certain abnormalities, leading to the occurrence of maternal and infant complications. Drug and non-drug therapy are the basic methods of pain control in clinical obstetrics department, mainly including spinal nerve block anesthesia, acupuncture analgesia, doula accompanied delivery, Lamaze pain relieving delivery, water delivery and so on. This study was conducted to investigate the effect of percutaneous electrical nerve stimulation on labor analgesia in puerpera.

Abstract: a total of 88 cases of parturient women giving birth in our hospital were randomly divided into control group and observation group, with 44 cases each. In the control group, the parturient women were subjected to labor analgesia by routine methods. In the observation group, parturient women were treated with percutaneous electrical nerve stimulation for labor analgesia. The effects of labor analgesia, the improvement of VAS score before and after labor analgesia intervention, the duration of labor, the total duration of hospitalization, and the number of postpartum adverse events were compared between the two groups.

Results: The analgesic effect of pregnant women in the observation group was significantly better than that in the control group, with significant difference between groups (P<0.05). VAS score before and after labor analgesia intervention was significantly improved compared with the control group, with significant difference between groups (P<0.05). The duration of labor and total length of hospitalization were significantly shorter than those of the control group, with significant differences between groups (P<0.05). The number of postpartum adverse events was significantly lower than that of the control group, with significant difference between groups (P<0.05).

Conclusion: The clinical effect of percutaneous electrical nerve stimulation on labor analgesia is very obvious.
