title: [Results of a clinical trial of the Dilapan hygroscopic cervical dilator].
abstract: The authors used Dilapan to dilate the cervical canal in women with induced abortion during the first trimester. Its effect was followed up in a group of pregnant women without preceding pregnancies (88 pregnant women). The dilator remained in the cervical canal from 90 to 210 min. The best results (dilation within 9--10 min) were achieved after its stay in the cervical canal for 3 to 3 1/2 h. In the group of nulliparas dilation of 10 sm was achieved in 49.5% of the cases after stay of dilator for a period of 120 to 180 min. The authors think that the usage of Dilapan is a method by which could be achieved lowering of the frequency of cases with isthmian-cervical incompetence. Application of Dilapan is of special value in women, who have not endured preceding abortions and deliveries and are pregnant for the first time.
