A comparison was made between three methods of local prostaglandin F2 alpha application for medicamentous induction of interruption in 375 primigravidae in the first trimester. They were extra-amniotic transcervical application, intracervical instillation of gel, and intracervical application, using a portio adaptor according to Fikentscher/Semm. Retrospective and prospective analyses were made of 125 unselected patients for each of the three methods, and the portio adaptor technique proved to be most effective of all with regard to non-invasive cervix dilatation. This method, when compared to others, was found to be best acceptable to patients and medical personnel alike, with no risk of subsequent ascending infection and with lowest prostaglandin consumption.
对375例孕早期初产妇采用三种局部应用前列腺素F2α药物引产方法进行了比较。这三种方法分别是经宫颈羊膜外给药、宫颈内凝胶滴注以及使用根据菲肯切尔/塞姆方法制作的宫颈阴道部适配器进行宫颈内给药。对每种方法的125例未经筛选的患者进行了回顾性和前瞻性分析，结果表明，就无创性宫颈扩张而言，宫颈阴道部适配器技术最为有效。与其他方法相比，该方法最易被患者和医护人员接受，无后续上行感染风险，且前列腺素消耗量最低。
