ObjectiveTo observe the effect of transcutaneous electrical acupoint stimulation (TEAS)combined with epidural analgesia on postpartum depression and to explore its underlying mechanism.MethodsOne hundred and twenty cases of full-term primiparous women with singleton pregnancy were selected from May 2018 to November 2018 in Jinzhong Maternal and Child Health Hospital. The parturients with labor analgesia requirement were randomly divided into the epidural group and the combination group, and the parturients without labor analgesia requirement were used as the control group, with 40 cases in each group. Patients in the control group did not receive labor analgesia and were treated according to the routine procedures of natural delivery; patients in the epidural group received epidural labor analgesia; patients in the combination group received TEAS at bilateral Hegu(LI4), Sanyinjiao(SP6) and Zusanli(ST36) (2 Hz/100 Hz, the current intensity is gradually increased from 15 mA, and the treatment was performed every 2 h, 20 min each time) combined with epidural labor analgesia. The visual analogue scale (VAS) scores were recorded when the uterine orifice opened to 3, 6, 8, 10 cm. Plasma glutamate was measured using high-performance liquid chromatography before analgesia, at the end of the third stage of labor and 42 days after delivery, and Edinburgh postnatal depression scale (EPDS) score was measured at 42 days after delivery.ResultsIn comparison with the control group, the VAS score, EPDS score and the incidence of postpartum depression of the epidural group and the combination group were significantly lower(P<0.05), and the combination group had significant decrease than those in epidural group (P<0.05). Immediately before analgesia, there was no statistically significant difference in glutamate levels among the 3 groups (P>0.05). Compared with the control group, at the end of the third stage of labor and 42 days postpartum, the glutamate levels of the epidural group and the combination group were significantly reduced(P<0.05), and the combination group decreased more significantly than the epidural group (P<0.05).ConclusionTEAS combined with epidural analgesia can reduce the incidence of postpartum depression, possibly by down-regulating plasma glutamate level and relieving of labor pain.
