Our purpose was to determine the optimal management of pregnancies beyond 41 weeks' gestation with a cervix unfavorable for induction.
All uncomplicated pregnancies that reached 41 weeks' gestation with a Bishop score of < or = 4 were randomly assigned to one of three groups: (1) daily cervical examinations, (2) daily membrane stripping, or (3) daily placement of prostaglandin gel until 42 weeks.
In 105 pregnancies the Bishop score on admission to labor and delivery was significantly greater in the groups receiving prostaglandin or stripping of the membranes versus the control group, whereas the converse was time of gestational age at delivery (p = 0.0001). Fewer patients required induction in the two treatment groups (20%, 17%) versus the control (69%) patients (p < 0.0001).
Daily membrane stripping or daily placement of prostaglandin gel is successful in reducing the number of inductions at 42 weeks for postdatism.
我们的目的是确定对于宫颈条件不利于引产的妊娠超过41周的最佳处理方法。
所有达到41周妊娠且 Bishop 评分≤4的无并发症妊娠被随机分为三组之一：（1）每日宫颈检查，（2）每日人工破膜，或（3）每日放置前列腺素凝胶直至42周。
在105例妊娠中，与对照组相比，接受前列腺素或人工破膜组在入院待产时的 Bishop 评分显著更高，而相反的是分娩时的孕周（p = 0.0001）。与对照组（69%）患者相比，两个治疗组中需要引产的患者较少（20%，17%）（p < 0.0001）。
每日人工破膜或每日放置前列腺素凝胶成功减少了过期妊娠在42周时的引产次数。
