观察卡孕栓促宫颈成熟临床效果。对象为因各种原因需引产的孕妇９４例，均为单胎足月头位初产，宫颈评分≤４分，随机分为两组，分别给予小剂量卡孕栓置阴道和硫酸普拉酮钠（ＤＨＡＳ）静脉注射，以４７例自然临产者作为对照组。结果：各组年龄、孕周及宫颈评分无差异。卡孕栓促宫颈成熟显效率（７２．３％）和在用药期间临产分娩率（６１．７％）明显高于ＤＨＡＳ组（分别为３１．９％和２１．３％）。两用药组与自然临产组比较各产程的时间、出血量和新生儿Ａｐｇａｒ评分无统计学意义。无明显副反应。讨论：本文结果说明卡孕栓促官颈成熟效果优于ＤＨＡＳ同时证明卡孕栓不仅是良好的宫颈软化和扩张剂，而且与分娩的动因有关。因此，本文认为小剂量卡孕栓用于足月妊娠促宫颈成熟是可行的，效果较好，总有效率达９５．７％。
Observation of card pregnancy suppository to promote the clinical effect of cervical ripening. The subjects were 94 pregnant women who needed induction of labor due to various reasons, all of whom were single-term full-term first-born, cervical score ≤4, were randomly divided into two groups, Sodium (DHAS) intravenous injection to 47 cases of natural labor as a control group. Results: There was no difference in age, gestational age and cervical score between groups. The rate of cervical ripening (72.3%) induced by carbamazepine and labor delivery rate (61.7%) during treatment were significantly higher than those in DHAS group (31.9% and 21.3% respectively). Compared with spontaneous labor group, the two groups had no statistical significance on the time of birth, the amount of bleeding and Apgar score of neonates. No obvious side effects. Discussion: The results of this study show that caramel suppository has a better neck maturity than DHAS. Simultaneously, Caramel suppository is not only a good cervical softening and dilating agent, but also related to the motivation of childbirth. Therefore, this paper suggests that low-dose carboplatin for full-term pregnancy cervical maturation is feasible, the effect is better, the total effective rate was 95.7%.
