【摘要】目的 通过分析普贝生用于足月妊娠羊水偏少的临床效果,探讨该药用于引产的有效性。方法 采用前瞻性研究方法,对我院2008年4月1日至2010年4月1日36例使用普贝生的足月妊娠羊水偏少的孕妇进行密切观察,同时,随机抽取36例该阶段使用催产素的足月妊娠羊水偏少的孕妇作为对照组,比较两组的宫颈评分改善、临产时间、引产成功率、总产程、阴道分娩率等情况的差异。结果 用药后普贝生组宫颈改善分值为(3.56±1.38)分,用药至临产时间(10.31±3.07)h,引产成功率为83.33%,阴道分娩率69.44%;催产素素组宫颈改善分值为(1.98±1.12)分,用药至临产时间(18.59±5.5)h,阴道分娩率41.72%,以上指标两者之间均具有显著性差异(p<0.05)。结论 普贝生能显著提高引产成功率,并有效缩短临产时间,降低剖腹产分娩率,对提高产科质量具有较大的临床应用价值。

【Abstract】Objective To analyze the clinic effects of Propess used for induction of term pregnancy with oligohydramnios. Methods There is a prospective study which choose 36 pregnants with oligohydramnios who used Propess as observing group and 36 pregnants with oligohydramnios who used Oxytocin as control group during April 1, 2008 to April 1, 2010. The study indicators included Bishop scores ,labor time, the rate of successful induction of labor, total labor time, the rate of vaginal delivery. Results There are some changes of Propess using group, just like, Bishop scores has raised (3.56±1.38),labor time is (10.31±3.07)h, the rate of successful induction of labor is 83.33%, the rate of vaginal delivery is 41.72%.There is significant different between Propess group and Oxytocin group (p <0.05). Conclusion Propess, which can significantly improve the rate of successful induction of labor, shorten the labor time, and increase the rate of vaginal delivery, has important value in induction of term pregnancy with oligohydramnios .

足月妊娠一直是大家极力关注的阶段,该阶段任何高危因素都将影响胎儿和孕妇的安全和健康。而足月妊娠羊水偏少是胎儿危险的重要信号,羊水偏少有可能导致胎儿宫内窘迫、新生儿窒息、围产儿病死率等显著增加。为保证母婴安全,足月妊娠羊水偏少需要适时终止妊娠[1]。但羊水偏少不是剖宫产的绝对手术指针,决定是否引产的一个重要因素是宫颈是否成熟,宫颈不成熟的孕妇需要借助药物以促宫颈成熟。普贝生是一种含前列腺素E2的持续控释剂,现已广泛运用于足月妊娠引产[2],但对于足月妊娠合并羊水减少的临床运用,国内还有待进一步研究。本研究通过对我院近两年来运用普贝生引产的足月妊娠羊水偏少产妇进行疗效观察,探讨普贝生对于该人群引产的有效性,研究结果如下:
