韩氏穴位神经刺激仪(HANS)用于分娩镇痛临床效应的观察及评价

CLINICAL EFFECT WITH HAN' S ACUPOINT NERVE STIMULATOR (HANS) FOR RELIVING LABOUR PAIN

目的 :以韩氏穴位神经刺激仪 (HANS)行变频体表电刺激用于分娩镇痛 ,并以病人自控硬膜外镇痛 (PCEA)对该方法的镇痛效果进行评价。方法 :将 80例产妇随机分为四组 ,Ⅰ组为HANS ,Ⅱ组为HANS安慰 +PCEA ,Ⅲ组为HANS +PCEA ,Ⅳ组为对照组 ,不予任何镇痛措施。结果 :Ⅰ组产妇应用HANS ,通过VAS评分推断 ,使分娩痛降低 33% ,其效果虽明显好于Ⅳ组 (P <0 .0 5) ,但却又明显低于Ⅱ组与Ⅲ组 (P <0 .0 5)。Ⅱ组与Ⅲ组VAS评分相似 ,但在局麻药用量及PCA需求次数上均有显著性差异 (P <0 .0 5) ,HANS用于分娩镇痛可减少利多卡因用量的 38%。结论 :以HANS镇痛 ,并以药物弥补其镇痛不全 ,即针药结合用于分娩 ,是一种既能消除产痛而又保证母婴安全的较好方法。

Objective: To observe the effect of HANS in relifing labour pain compared with PCEA. Method:80 pregnant women were randomly divided into 4 groups. Group I with HANS, group Ⅱ with HANS Placebo+PCEA, group Ⅲ with HANS+PCEA and group Ⅳ for control. Result:Pain threshold in group I increased 40% deducing through VAS Scoring,which was significantly effective than that in group Ⅳ( P <0.05), but less efficacious than that in group Ⅱand group Ⅲ( P <0.05). The VAS Scores in group Ⅱ and grorp Ⅲ showed no difference, but the dosage of local anaesthetic used and the frequency of attempts for PCEA showed marked difference( P <0.05). Thus HANS used in labour pain can decrease the dosage of lidocaine by 39%. Conclusion: HANS combined with local anacsthetic for labour pain is an efficent method which can not only relif pain but ensure the safety both for mother and her newborn infant.
