The effect of epidural morphine on the duration of action of epidural 2-chloroprocaine was studied in a double-blind fashion in 30 patients following elective Caesarean section. When compared to epidural saline controls (n = 15), patients (n = 15) who received epidural morphine (4.0-5.0 mg) did not experience a prolongation or reduction in the duration of the somatic or sympathetic nervous system blockades produced by epidural 2-chloroprocaine.
在30例行择期剖宫产术后的患者中,以双盲方式研究了硬膜外注射吗啡对硬膜外注射2-氯普鲁卡因作用持续时间的影响。与硬膜外注射生理盐水的对照组(n = 15)相比,接受硬膜外注射吗啡(4.0 - 5.0毫克)的患者(n = 15),其由硬膜外注射2-氯普鲁卡因所产生的躯体或交感神经系统阻滞的持续时间并未延长或缩短。
