电针三阴交穴对产程的影响及安全性观察

Clinical observation of the impacts and safety of electroacupuncture at Sanyinjiao (SP 6) on labor

目的:观察电针三阴交对产程的影响,并评价其安全性。方法:采取随机、单盲方法将111例自然分娩的产妇随机分为电针组(38例)、安慰电针组(37例)和空白对照组(36例)。电针组选取三阴交穴,并接韩氏穴位神经刺激仪;安慰电针组是将套管中心的针取出,空弹套管,使产妇感到被针刺,然后迅速将已用胶布包住针尖的毫针贴于三阴交,电针方式与电针组相同,但其中一根导线被剪断;空白对照组不做任何治疗,仅在相应时间点观察记录。3组分别在电针20min、起针后30min测量产妇血压、心率及胎儿胎心率;观察产后24h出血和新生儿1分钟Apger评分。结果:电针组第1产程活跃期(4.38±1.76)h均短于空白对照组(5.28±2.41)h和安慰电针组(5.38±2.36)h,差异均有统计学意义(均P<0.05);第1产程潜伏期、第2、3产程,电针后产妇的血压、心率及胎儿胎心率,产后24h出血和新生儿1分钟Apger评分3组比较,差异均无统计学意义(均P>0.05)。结论:电针三阴交穴可以缩短第1产程活跃期,并对产妇和胎儿安全,为临床提高分娩质量提供帮助。

Objective To observe the impacts of electroacupuncture（EA） at Sanyinjiao（SP 6） on labor and assess its safety.Methods The random and single-blind method was adopted to divide 111 cases of the puerperas of natural delivery into an EA group（38 cases）,a sham-acupuncture group（37 cases） and a blank control group（36 cases）.In EA group,Sanyinjiao（SP 6） was selected and stimulated with Han＇s acupoint nerve stimulator（HANS）.In the sham-acupuncture group,the puerperas were stimulated only with the needle tube,needle removed in advance and they felt subjectively to be needled.Afterward,the filiform needle was attached to Sanyinjiao（SP 6） with the needle tip wrapped with the adhesive plaster in advance,then HANS which one conducting wire was cut off in was connected.In the blank control group,no any treatment was applied,but the same indices were recorded at corresponding time points.The blood pressure and the heart rate of the puerperas as well as the heart rate of fetus were measured in 20 min of EA and 30 min after needle removal in three groups separately.The bleeding 24 h after labor and 1 min Apger score of the newborns were observed.Results In EA group,the active phase of the 1st labor stage（（4.38±1.76）h） was shorter than that（（5.28±2.41）h） in the blank control group and that（（5.38±2.36）h） in the sham-acupuncture group,presenting statistically significant differences（all P0.05）.In the latent phase of the 1st labor stage and the 2nd and 3rd stages,in the comparison of the blood pressure and the heart rate of the puerperas as well as the heart rate of fetus after EA,the bleeding 24 h after labor and 1 min Apger score of the newborns among three groups,there were no statistically significant differences（all P0.05）.Conclusion EA at Sanyinjiao（SP 6） can shorten the duration of the active phase of the 1st labor stage.It is safe for either the puerpera or the fetus and can assist the parturition quality in clinic.
