经皮神经电刺激用于宫腔镜检术后止痛的疗效观察

Curative effect of transcutaneous electric nervous stimulation on pain relief after hysteroscopy

目的观察经皮神经电刺激(TENS)用于宫腔镜检术后止痛的疗效。方法选择2017-01~2018-07在该院妇科进行宫腔镜检查手术的450例患者作为研究对象,将研究对象随机分为TENS治疗组、药物治疗组以及安慰剂对照组各150例,采用视觉模拟评分法(VAS)比较治疗前、治疗后30、60、120 min三组疼痛评分的变化。结果三组患者治疗前VAS评分差异无统计学意义(P>0.05)。治疗后30 min,TENS治疗组VAS评分较治疗前有下降,差异有统计学意义(P<0.05),药物治疗组和安慰剂对照组治疗前后VAS评分无明显变化。治疗后60 min,TENS治疗组、药物治疗组、安慰剂对照组VAS评分较治疗前下降,差异有统计学意义(P<0.05),TENS治疗组和药物治疗组较安慰剂对照组VAS评分下降更为明显,差异有统计学意义(P<0.05)。治疗后120 min,三组VAS评分继续较前下降,治疗前后差异有统计学意义(P<0.05),但三组间VAS评分差异无统计学意义(P>0.05)。结论TENS对疼痛治疗效果安全确切,有可能成为治疗宫腔镜检查手术后疼痛的主要方法。

Objective To observe the curative effect of transcutaneous electric nervous stimulation(TENS)on pain relief after hysteroscopy.Methods Four hundred and fifty patients who underwent hysteroscopic surgery in the Department of Gynecology,the People′s Hospital of Guangxi Zhuang Autonomous Region from January 2017 to July 2018 were selected as the research subjects.The research subjects were randomly divided into TENS treatment group,drug treatment group and placebo control group,with 150 cases in each group.The changes of pain scores before and 30,60,120 min after treatment were compared by Visual Analogue Scale(VAS)scoring method among the three groups.Results There were no significant differences in the VAS scores before treatment among the three groups(P>0.05).Compared with those before treatment,the VAS scores of the TENS treatment group were significantly decreased after 30 minutes of treatment(P<0.05).There were no significant changes in VAS scores before and after treatment in the drug treatment group and the placebo control group.Compared with those before treatment,the VAS scores were significantly decreased after 60 minutes of treatment in the three groups(P<0.05),and the reductions of VAS scores in the TENS treatment group and the drug treatment group were more obvious than those in the placebo control group(P<0.05).After 120 minutes of treatment,the VAS scores of the three groups continued to decline,and the differences before and after treatment were statistically significant(P<0.05).However,there were no significant differences in VAS scores among the three groups(P>0.05).Conclusion TENS is safe and effective in pain management and may be a main method to relief pain after hysteroscopy.
