目的:探讨地诺前列酮栓(缓释性前列腺素E2栓)用于单胎足月妊娠引产的临床效果。方法:采用对照研究的方法,选择200例足月单胎头先露、宫颈Bishop评分小于或等于6分、有引产指征且无母婴禁忌症的初产妇,为其阴道内使用地诺前列酮栓,作为观察组;选择同样条件的200例静脉点滴催产素的产妇为对照组,比较两组孕妇的宫颈Bishop评分、治疗成功率、用药到临产平均时间、剖宫产率、产后出血量及新生儿窒息率。结果:观察组给药后宫颈Bishop评分明显高于对照组,剖宫产率降低,两组产后出血量及新生儿窒息发生率比较,差异无统计学意义。宫缩过强是地诺前列酮栓的主要副作用,但其发生率仅为2%,取药后即好转。结论:地诺前列酮栓能有效促进妊娠晚期的宫颈成熟,缩短产程,提高宫颈Bishop评分及阴道分娩率,降低剖宫产率,可在足月妊娠引产中推广使用。
Objective: To investigate the clinical effect of dinoprostone suppository (controlled release prostaglandin E2 suppository) for induction of labor during singleton full-term pregnancy. Methods: A controlled study of 200 cases of single-head first-term debridement, cervical Bishop score less than or equal to 6 points, induction of labor indications and no maternal and child contraindications in primipara, Ketone plug as the observation group; select the same conditions of 200 cases of intravenous oxytocin maternal for the control group, compared the two groups of pregnant women’s cervical Bishop score, the success rate of treatment, medication to labor average time, cesarean section rate, postpartum hemorrhage And neonatal asphyxia rate. Results: The Bishop score of the cervix in the observation group was significantly higher than that in the control group, and the cesarean section rate was decreased. The postpartum hemorrhage volume and the incidence of neonatal asphyxia in the two groups showed no significant difference. Contractions too strong is the main side effect of dinoprostone suppository, but its incidence was only 2%, after taking the medicine improved. Conclusion: The dinoprostone suppository can effectively promote cervical ripening in the third trimester of pregnancy, shorten the labor process, improve cervical Bishop score and vaginal delivery rate, reduce the rate of cesarean section, and can be used in full-term pregnancy induced labor.
