背腧穴皮下注射利多卡因进行分娩镇痛的临床观察

目的:观察背腧穴皮下注射1%利多卡因用于分娩镇痛的效果及对母婴的影响。方法:将120例初产妇随机分为3组,Ⅰ组为对照组,Ⅱ组为灭菌注射用水组,Ⅲ组为利多卡因组。在进入活跃期后,Ⅰ组无镇痛干预,Ⅱ、Ⅲ组在宫口开大3 cm后行背腧穴皮下注射,半小时后采用视觉模拟量表(VAS)评分法评价镇痛效果。结果:VAS评分Ⅱ组和Ⅲ组均较Ⅰ组显著降低(P0.05),Ⅲ组较Ⅱ组明显降低(P0.05);产妇中转剖宫产、产后出血、新生儿窒息的发生机率及产程进展3组比较,差异均无统计学意义(P0.05)。结论:背腧穴皮下注射1%利多卡因用于分娩镇痛效果良好,且对于分娩方式和新生儿无不良影响。

Clinical Observation on Subcutaneous Injection of Lidocaine at Back-shu Points for Labor Analgesia

Objective: To observe the effects of subcutaneous injection of 1% lidocaine at back-Shu points for labor analgesia and its influence on the mother and baby. Methods: All 120 patients were randomized into three groups: the group Ⅰas the control group, the group Ⅱas the group of sterilized water for injection and the group Ⅲas the group of lidocaine. After entering the active stage, the group Ⅰwere unhandled, the group Ⅱand Ⅲaccepted subcutaneous injection of lidocaine at back-Shu points when the cervix dilated to three cm, analgesic effects were assessed by adopting VAS in half an hour. Results: The group Ⅱand Ⅲwere lower than the group Ⅰin pain scales notably (P<0.01), the group Ⅲwas more notable compared with the group Ⅱin the decrease obviously (P<0.05); the difference had no statistical meaning in the comparison of the incidences of puerperant transforming into cesarean section, postpartum hemorrhage, neonatal asphyxia and the progress of labor among three groups (P>0.05). Conclusion: Subcutaneous injection of 1% lidocaine at back-Shu points is effective for labor analgesia, and it shows no bad effects to delivery methods and the neonates.
