Abstract：
UNASSIGNED: The use of transcutaneous electrical nerve stimulation (TENS) to relieve labor pain remains controversial and existing evidence is neither strong nor consistent. This research was designed to compare TENS\' effect with the injection of pethidine and promethazine in labor pain reduction.
UNASSIGNED: In this trial, for 45 pregnant women in the active phase of labor, TENS electrodes were placed (two on both arms, and two over the participants\' low back) continuously for 120 minutes; and for another group 45 pregnant women, 100 milligrams of pethidine and 250 micrograms of promethazine were injected intramuscularly which could be repeated once at least one hour later. Labor pain and duration, need for labor induction/augmentation/other pain control methods/ instrumental delivery, delivery type, and maternal and newborn complications were measured in both groups.
UNASSIGNED: The baseline mean visual analog scale (VAS) score, in the TENS group was 8.51±0.62 and in the pethidine and promethazine groups was 8.37±0.61 (P=0.31). While in a 120min post-intervention, it was 6.29±1.50 and 5.73±1.46 in the TENS group and the pethidine and promethazine group, respectively with no statistically significant difference (P=0.07). The labor duration in the TENS group was 6.61±1.71 hours and in the pethidine and promethazine group was 6.17±2.07 hours, with no statistically significant difference (P=0.33). In addition, no complication was recorded neither in the mothers nor newborns.
UNASSIGNED: This study showed that applying TENS in the active labor phase can reduce at least two scores in patient labor pain with no significant complications.

摘要：
■使用经皮神经电刺激（TENS）缓解分娩疼痛仍然存在争议，现有证据既不强烈也不一致。这项研究旨在比较TENS与注射哌替啶和异丙嗪在减轻分娩疼痛方面的效果。
■在此试验中，45名处于活跃期的孕妇，放置了TENS电极（两个手臂，和两名参与者的下背部)连续120分钟；另一组45名孕妇，肌内注射100毫克哌替啶和250微克异丙嗪，至少一小时后可重复一次。分娩疼痛和持续时间，需要引产/增加/其他疼痛控制方法/器械分娩，交货类型,并对两组产妇和新生儿并发症进行测量。
■基线平均视觉模拟量表（VAS）评分，TENS组为8.51±0.62，哌替啶和异丙嗪组为8.37±0.61(P=0.31)。在干预后120分钟，TENS组和哌替啶和异丙嗪组分别为6.29±1.50和5.73±1.46，差异无统计学意义(P=0.07)。TENS组的产程为6.61±1.71小时,哌替啶和异丙嗪组的产程为6.17±2.07小时,差异无统计学意义(P=0.33)。此外,母亲和新生儿均未出现并发症.
■这项研究表明，在积极分娩阶段应用TENS可以在患者分娩疼痛中减少至少两个得分，而没有明显的并发症。
