经皮神经电刺激分娩镇痛的疗效观察

Observation of the efficacy of transcutaneous electric nerve stimulation in labor analgesia

目的:探讨经皮神经电刺激(TENS)的分娩镇痛效果及安全性.方法:将入选后有分娩镇痛要求的孕妇随机分为2组,即TENS组和腰硬联合麻醉(CSEA)组,同期无分娩镇痛要求的孕妇设为空白对照组,每组各50例.观察并比较3组中成功阴道分娩孕妇的VAS疼痛程度评分,血清强啡肽浓度,产程及母儿妊娠结局.结果:镇痛效果各组间相比,TENS组和CSEA组的VAS疼痛评分均较空白对照组明显降低,CSEA组最低(P<0.05);镇痛后TENS组孕妇血清强啡肽明显升高(P<0.05);TENS组与空白对照组相比,产程和母儿结局均无统计学差异(P>0.05).结论:TENS在一定程度上减轻分娩疼痛,分娩镇痛安全有效,不影响产程.

Aim：To study the efficacy and security of transcutaneous electric nerve stimulation （TENS）.Methods：Laboring women who needed analgesia were divided into TENS group and CESA group （combined spinal epidural anesthesia）randomly,while women without analgesia during labor were selected as blank control group.Each group was included 50 cases.We analyzed and compared the difference between these three groups in the level of labor pain,concentration of serum dynorphin,duration and outcome of labor.Results：The level of labor pain alleviated significantly in TENS and CSEA groups,and even more in CSEA group（P 〈0.05）.The concentration of serum dynorphin increased significantly in TENS group after treatment （P 〈0.05）;the duration and outcome of labor showed no significant difference between TENS and blank control group（P〉0.05）.Conclusion：TENS could reduce the pain of labor safely and effectively without affecting the labor process.
