This study aimed to investigate the analgesic effect of transcutaneous electrical acupoint stimulation (TEAS) on labor.
Primiparas with single birth and head presentation were enrolled in this study and randomly divided into three groups: TEAS group (n = 76), patient-controlled epidural analgesia (PCEA) group (n = 75), and control group without any analgesic measures (n = 78).
Compared with the control group, the visual analog scores of the TEAS group and the PCEA group at each time point decreased (P < 0.01). The decrease was greater in the PCEA group than that in the TEAS group (P < 0.01). At 120 minutes after analgesia, there were significant differences in plasma β-endorphin content between the TEAS group, PCEA group, and control group (P < 0.01). The difference between the PCEA group and the control group was statistically significant (P < 0.01). Among the parturients having a vaginal delivery, the duration of the first stage of labor was significantly shorter in the TEAS group and control group than in the PCEA group (P < 0.01). The duration of the second stage of labor was significantly shorter in the TEAS group than in the PCEA group (P < 0.01). Oxytocin usage rate during labor was significantly lower in the TEAS group and control group than in the PCEA group (P < 0.01), and adverse reactions were significantly fewer in the TEAS group and control group than in the PCEA group (P < 0.01).
The duration of the first and second stage of labor is significantly shorter in the TEAS group than in the PCEA group. TEAS does not increase the use rate of oxytocin or the rate of cesarean section and will not bring about obvious maternal or fetal adverse reactions.
本研究旨在探讨经皮穴位电刺激（TEAS）对分娩的镇痛效果。
选取单胎头位初产妇纳入本研究，并随机分为三组：TEAS组（n = 76）、患者自控硬膜外镇痛（PCEA）组（n = 75）和无任何镇痛措施的对照组（n = 78）。
与对照组相比，TEAS组和PCEA组各时间点的视觉模拟评分均降低（P < 0.01）。PCEA组的降低幅度大于TEAS组（P < 0.01）。镇痛120分钟后，TEAS组、PCEA组和对照组血浆β-内啡肽含量存在显著差异（P < 0.01）。PCEA组与对照组之间的差异具有统计学意义（P < 0.01）。在经阴道分娩的产妇中，TEAS组和对照组第一产程的持续时间明显短于PCEA组（P < 0.01）。TEAS组第二产程的持续时间明显短于PCEA组（P < 0.01）。TEAS组和对照组分娩期间催产素使用率明显低于PCEA组（P < 0.01），TEAS组和对照组的不良反应明显少于PCEA组（P < 0.01）。
TEAS组第一、第二产程的持续时间明显短于PCEA组。TEAS不会增加催产素使用率或剖宫产率，也不会带来明显的母婴不良反应。
