目的：探讨卡前列甲酯口含片预防产后出血的效果。方法：选择１０３ 例正常足月妊娠阴道分娩者，随机分为试验组和对照组。试验组５３ 例，在胎儿娩出后产妇舌下含１ ｍ ｇ 卡前列甲酯片；对照组５０ 例，在胎儿娩出后肛塞卡前列甲酯栓１ 枚（１ ｍ ｇ），观察产后２ ｈ 的出血量。结果：产后２ ｈ 内平均出血量，口含片试验组与肛门直肠给药对照组分别为（１３６．６±５５．１） ｍ ｌ和（１４９．４±５８．８） ｍ ｌ，试验组与对照组相比，差异不显著（Ｐ＞ ０．０５）。结论：卡前列甲酯口含片有与卡前列甲酯栓相同的缩宫作用，能够减少产后出血量，而且口含片用药方法简便，非常适于向基层单位推广使用
Objective: To investigate the effect of card-top methyl ester tablets in preventing postpartum hemorrhage. Methods: 103 cases of normal term pregnancy vaginal delivery were randomly divided into experimental group and control group. In the experimental group, 53 cases received maternal sublingual gonadotropin 1 mg submandibularly after the fetus was delivered. In the control group, 50 cases received analgesic methyl ester bolus 1 (1 m g) The amount of bleeding. Results: The average amount of bleeding within 2 h postpartum was (136.6 ± 55.1) m l and (149.4 ± 58.8) m l in the buccal test group and the anorectal rectum test group, respectively Compared with the control group, the difference was not significant (P> 0.05). CONCLUSION: Cardioprotective methylester buccal tablets have the same contraction effect as prepar methyl ester suppository, which can reduce the amount of postpartum hemorrhage. Moreover, buccal tablets are easy to use and are very suitable for popularizing to grass-roots units
