Vaginal dinoprostone versus oral misoprostol for predilatation of the cervix in first trimester surgical abortion.
Prostaglandins are effective in predilatation of the cervix prior to first trimester surgical termination of pregnancy under local analgesia. Arandomized open comparative trial was devised to compare the effectiveness and acceptability of vaginal dinoprostone with oral misoprostol. Two groups were randomized to control for age, parity and ethnicity. The operation was easier and less painful in older, parous, and Polynesian women. Both methods were effective with respect to ease of dilatation. Both were acceptable and equal with respect to the level of pain experienced by the woman during the operation. Vaginal dinoprostone is more gradual in its action, but it is more expensive, has to be refrigerated and self-insertion may sometimes cause problems. Oral misoprostol is considerably cheaper and does not require refrigeration, but it was associated with more preoperative nausea, cramping and occasional heavy bleeding.
