title: [Cervical ripening and drug dilatation for birth control operations].
abstract: Cervical ripening in induced labor at second trimester of pregnancy was studied in 81 cases. The method consisted of injecting diazepam gel through Foley's catheter, into the extra-amniotic space, and at the level of cervical internal os. The cervix was found to be softened, the time interval between induction and onset of labor shortened and there was no cervical laceration. A comparison between the experimental and control groups showed significant difference. The use of suppositories for cervical dilatation in 719 cases of induced abortion and 34 cases of insertion and/or removal of IUD was also studied. The results were satisfactory. The mechanism of cervical dilatation and ripening with drug had been investigated at different periods of pregnancy and in non-pregnant women as well.
