目的探讨卡孕栓预防产后出血的效果。方法选择正常足月阴道分娩者８０例，每例于胎头娩出后给药，依给药途径不同分为三组，Ⅰ组为舌下含化卡孕栓１ｍｇ；Ⅱ组为阴道内放置卡孕栓１ｍｇ；Ⅲ组为肌肉注射催产素１０Ｕ。观察第三产程时间及产后２小时内出血量。结果第三产程平均时间分别为６．８分钟（Ⅰ组）、８．３分钟（Ⅱ组）、及１０．８分钟（Ⅲ组），Ⅰ组与Ⅲ组之差别有显著意义（Ｐ＜０．０５）；产后２小时内平均出血量三组分别为１６８．７ｍｌ、１５５．０ｍｌ及２４０．７ｍｌ，Ⅰ、Ⅱ组与Ⅲ组之比均有极显著意义（Ｐ＜０．０１）。结论卡孕栓比催产素具有更强的缩宫作用，能预防产后出血，卡孕栓舌下给药更方便
Objective To investigate the effect of carbamazepine on prevention of postpartum hemorrhage. Methods Eighty normal vaginal delivery patients were selected. Each case was given after the birth of the fetal head, which was divided into three groups according to the route of administration. Group I was hypoglycemic carboplatin (1mg); group II Pregnant suppository 1mg; Ⅲ group intramuscular oxytocin 10U. Observe the third stage of labor and the amount of bleeding within 2 hours after delivery. Results The average time of the third stage of labor was 6.8 minutes (group Ⅰ), 8.3 minutes (group Ⅱ), and 10.8 minutes (group Ⅲ). The difference between group Ⅰ and group Ⅲ was significant (P0.01 .05). The average amount of bleeding within two hours after delivery was 168.7ml, 155.0ml and 240.7ml, respectively. The ratio of group Ⅰ, Ⅱ and Ⅲ was significant (P <0.01). Conclusions Kapusi suppository has a stronger contraction effect than oxytocin and can prevent postpartum hemorrhage.
