现代产科临床中计划分娩是切实可行的。影响引产成功的一个因素是子宫颈情况。如果宫颈不成熟(宫口未开、宫颈质硬、宫颈管未消),采用人工破膜困难,采用催产素引产产程长使母婴有一定危险。引产失败而导致剖腹产率增加。因此有必要寻找一种促使宫颈成熟的方法。很多作者报告不同途径给予 PGE_2可促使宫颈成熟引产成功,但对不同剂量的效果比较方面涉及较少。本文系对三种不同剂量 PGE_2阴道栓剂效果作比较研究。本研究将180例病人根据所给 PGE_2不同剂量分为三组。Ⅰ组:
Modern obstetric clinical plan delivery is feasible. One factor that affects the success of induction is the cervical condition. If the cervix is not mature (cervix is not open, cervical hard, cervical tube is not eliminated), the use of artificial rupture of membranes, the use of oxytocin induction of long process of mother and child have a certain risk. Induction of labor leads to increased caesarean section rate. Therefore, it is necessary to find a way to promote cervical maturation. Many authors report that different routes of administration of PGE_2 may lead to cervical ripening successful induction, but the effects of different doses less involved. In this paper, three different doses of PGE_2 vaginal suppository for comparative study. In this study, 180 patients were divided into three groups according to different doses of PGE 2. Group Ⅰ:
