O Tang, K Thong, D Baird (2001) Second trimester medical abortion with mifepristone and gemeprost: a review of 956 cases Contraception (IF: 2.3) 64(1) 29-32Abstract
The treatment outcomes of 956 women undergoing second trimester termination of pregnancy with mifepristone and gemeprost were studied. The median gestational age was 16 weeks (range: 12-24 weeks). All women were treated with 200 mg mifepristone orally, followed 36 h later with 1 mg vaginal gemeprost administered every 6 h to a maximum of 4 doses in the first 24 h. A second course of 1 mg vaginal gemeprost was given 3-hourly in the next 12 h, if abortion had not occurred. Overall, 96.4% and 98.8% of the women aborted within 24 and 36 h, respectively. The median induction-to-abortion interval was 7.8 h (range: 0.5-109.9 h). The induction-abortion interval was longer in nulliparous women and women with a gestation age 17 weeks or above. Surgical evacuation of the uterus was performed in 11.5% of women for incomplete abortion or retained placenta. More multiparous women (16.7%) required surgical evacuation of uterus than did nulliparous women (7.3%; p <0.001). Ten (0.1%) women failed to abort with gemeprost and required other methods for abortion. In conclusion, a combination of mifepristone and gemeprost is a safe, effective, and noninvasive method of medical abortion for second trimester pregnancy.
