穴位电刺激与椎管内麻醉应用于经产妇分娩镇痛的效果比较

目的对比分析穴位电刺激与椎管内麻醉对经产妇分娩疼痛及产程的影响。方法选取400例经产妇,进入产程活跃期后根据产妇分娩镇痛方式分为穴位电刺激组(观察组)和椎管内麻醉组(对照组),各200例。比较两组产妇不同时间点的VAS评分、产程时间、羊水污染率、产后2 h出血情况及新生儿出生后1 min和5 min Apgar评分。结果在宫口活跃期、第二产程时,两组产妇VAS评分均较镇痛前明显降低,且观察组VAS评分高于对照组(均P<0.05);观察组的第一产程活跃期及第二产程、第三产程时间均明显短于对照组,且羊水污染率、产后2 h出血量明显低/少于对照组(均P<0.05);两组新生儿出生后1 min、5 min Apgar评分情况比较,差异均无统计学意义(均P>0.05)。结论穴位电刺激与椎管内麻醉均可缓解经产妇分娩疼痛,但穴位电刺激较椎管内麻醉对经产妇宫缩的影响小,产程时间明显缩短,羊水污染率明显降低,产后出血明显减少。

Effect of electrical acupoint stimulation versus intraspinal anesthesia in the application of multipara delivery analgesia

Objective To compare and analyze the effects of electrical acupoint stimulation versus intraspinal anesthesia on multipara delivery ache and labor.Methods A total of 400 multipara were selected,who were in the active stage of labor,and they were assigned to electrical acupoint stimulation group(observation group)and intraspinal anesthesia group(control group)according to methods of delivery analgesia,with 200 cases in each group.The VAS scores in various time points,labor duration,incidence of amniotic fluid contamination,bleeding condition 2 h after delivery of puerpera,and 1-and 5-minute postnatal Apgar scores of newborns were compared between the two groups.Results The VAS scores in the uterus orifice active stage and the second labor significantly decreased in both groups as compared with before analgesia,and the scores mentioned above of the observation group were higher than those of the control group(all P<0.05).The observation group yielded shorter active stage of the first labor,and duration of the second and third labor as compared with the control group,whereas a lower incidence of amniotic fluid contamination,and less bleeding volume 2 h after delivery(all P<0.05).There were no statistically significant differences in 1-and 5-minute postnatal Apgar scores of newborns between the two groups(all P>0.05).Conclusion Electrical acupoint stimulation and intraspinal anesthesia can relieve multipara delivery ache;however,electrical acupoint stimulation has slighter effects on multipara uterine contraction as compared with intraspinal anesthesia,and the labor duration is prominently shorter,the incidence of amniotic fluid contamination is more decreased,and the postnatal bleeding is more reduced.
