硬膜外腔低浓度布比卡因用于无痛分娩的临床观察

CLINCAL APPLICATION AND INVESTIGATION OF EPIDURAL ANALGESIA WITH 0.125% BUPIVACAINE DURING LABOR

将硬膜外腔低浓度布比卡因阻滞用于无痛分娩，并进行了初步的临床对照研究。结果表明，此法安全有效，镇痛作用良好，运动阻滞作用轻微。镇痛组第二产程有所延长，器械助产率略高，催产素应用率较高且用量明显高于对照组．

To relieve labor pain, double-cathetered epidural blockages with 0. 125 % bupivacaine were usedin nulliparous womcn and this technique was investigated double-blindedly. The results demonstratedthat good pain-relief had been set up in bupivacaine-treated group. No serious adverse effects on laborcourses and neonatals were observed in this study. However, the labor force of pushing down seemsto have been retarded slightly as characterized by higher doses of oxytocine needed and higher acci-dence of instrumental delivery in the pain-relief group. It suggested that epidural analgesia may, tosome extent, slow down the labor process by influencing synergy of the mother's bearing down withthe uteral contractions.
