Association of extrauterine fetal death with failure of prostaglandin E2 suppositories.

The use of prostaglandin E2 vaginal suppositories is an effective method of uterine evacuation for patients with intrauterine fetal demise. Advanced extrauterine gestation, because of its rarity, is usually not a primary consideration for patients presenting with fetal death. This report presents 4 such cases and strongly suggests that, when this drug is used for the treatment of fetal death, failure to induce contractions and to effect uterine evacuation within a reasonable time should prompt the consideration of extrauterine pregnancy.
