The present study was aimed to compare the effects of the use of electroacupuncture and misoprostol in inducing labor in patients with Bishop score < 7 and to observe the characteristics of labor in both methods.
As much as 67 pregnant women with Bishop score < 7, single cephalic presentation with gestational age confirmed by first-trimester ultrasound, reactive cardiotocography, and amniotic fluid volume and estimated fetal weight within the respective normal ranges for gestational age were selected. They were randomized into 2 groups: electroacupuncture (AC) or misoprostol (M).
There were no significant differences regarding age, gestational age, fetal weight, parity, Bishop score, or indication for induction. Labor was the main outcome, which was obtained in both groups without significant difference regarding frequency (p = 0.07) and time of induction (p = 0.29). Absence of obstetric complication, higher duration of labor (p = 0.036), and tendency to a higher satisfaction of the patients (p = 0.046) were observed among patients of group AC. Higher frequency of cesarean sections (p = 0.014) and obstetric complications (9.3%) were observed among patients of group M.
Our results showed that electroacupuncture can be used to obtain cervical ripening, with similar results as compared with misoprostol, with a significantly higher frequency of vaginal deliveries and without occurrence of obstetric complications.
本研究旨在比较电针和米索前列醇在诱导 Bishop 评分<7 的患者分娩方面的效果，并观察两种方法的分娩特点。
选择 67 例 Bishop 评分<7、单胎头位、经早孕超声确认的妊娠妇女，反应性胎心监护，羊水和估计胎儿体重均在各自的相应胎龄正常范围内。将其随机分为电针（AC）或米索前列醇（M）组。
两组间年龄、孕周、胎儿体重、产次、Bishop 评分和引产指征均无显著差异。产程是主要结局，两组的产程频率（p=0.07）和引产时间（p=0.29）均无显著差异。AC 组的产妇中，无产科并发症、产程时间延长（p=0.036）和患者满意度较高（p=0.046）。M 组中剖宫产率（p=0.014）和产科并发症（9.3%）发生率较高。
我们的结果表明，电针可以用于宫颈成熟，与米索前列醇相比，具有相似的效果，阴道分娩率显著提高，且无产科并发症发生。
