title: Intravaginal misoprostol for medical evacuation of first trimester missed abortion.
abstract: Objective: To evaluate the safety and efficacy of intravaginal misoprostol for medical evacuation of first trimester missed abortions.Methods: Seven women with a transvaginal ultrasound diagnosis of a first trimester missed abortion were treated with 800 µg of misoprostol. Four 200 µg misoprostol tablets were placed intravaginally, and a repeat dose of 800 µg was repeated if products of conception were not expelled in 12 hours.Results: Five of seven of the medical evacuations were successful. The average gestational age for the patients was 9 weeks with a range of 8 3/7 to 9 3/7 weeks. The average time from insertion to complete passage of products of conception was 18 hours with a range from 5 hours 10 minutes to 50 hours. Only one patient in the successful group required the second dose of misoprostol. One patient completely passed products of conception 2 weeks after the 2 doses of misoprostol and was considered a treatment failure. Another patient passed products of conception within 12 hours following insertion of the misoprostol but required a dilatation and curettage 3 days later and was also considered a treatment failure. Side effects included cramping in all patients, which was noted to be moderate in six and mild in one. One patient also had mild nausea, mild headache, and one episode of diarrhea. The average blood loss was estimated at 434 mL with a range from 171 to 871 mL.Conclusion: Intravaginal misoprostol for medical evacuation of first trimester missed abortions appears to be safe and effective and may be an alternative to dilatation and curettage.
