In 40 pregnant women who had exceeded term and presented "immature" portio uteri a priming with prostaglandin F2 alpha was carried out. A new procedure of local application using a portioadapter was tried. This synthetic adapter was inserted over the uterine cervix by means of vacuum suction, filled with a mixture of 15 mg PG F2 alpha and methyl-cellulose ether, left in place for 6 hours and then removed. The control examination after the removal of the adapter showed a highly significant improvement of the cervical score in the nulliparae as well as in the multiparae group. In 7 cases the PG-filled adapter was inserted twice. Two cases (5%) had to be considered therapeutic failures because of insufficient cervical maturation. The method described should not be interpreted as birth induction but should be understood to be a preparation for the start of planned artificial birth.
对40名过期妊娠且宫颈“不成熟”的孕妇进行了前列腺素F2α预处理。尝试了一种使用宫颈适配器进行局部应用的新方法。这种合成适配器通过真空抽吸插入子宫颈，填充15毫克前列腺素F2α和甲基纤维素醚的混合物，留置6小时后取出。取出适配器后的对照检查显示，初产妇和经产妇组的宫颈评分均有高度显著改善。7例患者中，填充前列腺素的适配器插入了两次。2例（5%）因宫颈成熟不足被视为治疗失败。所描述的方法不应被解释为引产，而应被理解为计划中的人工分娩开始前的准备。
