  [摘要] 目的:研究小剂量盐酸托烷司琼经硬膜外给药对剖宫产术中呕吐的影响。方法：150例ASA分级1/2级的择期行剖宫产术孕妇随机分为3组，均经硬膜外予1.2%盐酸利多卡因、0.25%丁卡因的混合液10 ml。待胎儿娩出后，Ⅰ组经硬膜外予盐酸托烷司琼0.5 mg,Ⅱ组经静脉给予盐酸托烷司琼5 mg,Ⅲ组为不使用任何止吐药物的对照组。结果：(1) 3组孕妇术中呕吐发生率分别为4%、6%和64%，Ⅰ、Ⅱ组间无显著性差异(P>0.05)，而Ⅰ、Ⅱ组与Ⅲ组比较均有显著性差异(P0.05)，而Ⅰ、Ⅱ组与Ⅲ组比较均有显著性差异(P1, ZHANG Yue1, XU Feng1, WANG Yan-juan2

 [Abstract] Objective: To study the effect of small dose triopisetron hydrochloride administered epidurally during cesarean section. Methods: 150 subjects of cesarean section scaled Ⅰ/Ⅱ by AS were divided into three groups randomly. Epidural administration of 1.2% hydrochloric acid lidocaine,0.25% teracainum in an amount of 10 ml was given to all；after the delivery of the fetus，group Ⅰ was administrated epidurally with 0.5 mg hydrochloric acid tropisetron; group Ⅱ was administrated through vein with 5 mg hydrochloric acid tropisetron; group Ⅲ served as a blank group with no medication.Results: (1) The frequency of vomiting in three groups was 4%, 6% and 64% respectively; no obvious difference was seen between group Ⅰ and group Ⅱ(P>0.05), but there was an obvious difference between group Ⅰ and group Ⅲ or group Ⅱ and group Ⅲ(P
