[Preoperative priming with Prepidil gel and laminaria in the first trimester of pregnancy].

To study possibilities of prevention of late sequelae of first trimester dilatation and curettage, such as cervical incompetence, spontaneous abortions and premature deliveries in aftercoming pregnancies, we used cervical preoperative priming with Prepidil gel and laminariae. The study included 60 primigravidas who were 6-10 weeks pregnant. Six hours included preoperatively one subgroup was treated with laminariae intracervically. Success of cervical priming was compared with so called ideal cervical score. In relation to such criteria the success in Prepidil group was 88%, and in laminaria group 82%. This difference was not significant. It could be concluded that preoperatively undertaken cervical priming with prostaglandins and laminariae successfully increased cervical score, cervical resistance being reduced in that way. In this gestational period such priming makes abortion less dangerous procedure and it lessens the possibility of different early and late complications of first trimester dilatation and curettage.
