Complications following prostaglandin F2alpha-induced midtrimester abortion.
Prostaglandin F2alpha (PGF2alpha) was injected intraamniotically in 122 patients between 14 and 20 weeks' gestation in the dosage schedule recommended by the drug manufacturer to induce abortion. Significantly more multiparous (47.5%) than primagravida patients (21.5%) aborted within 16 hours, but the mean duration between PGF2alpha injection and abortion was not significantly different. Complications occurred in 52 (42.6%) patients and included: fall in hematocrit of more than 5 percentage points, failure to abort within 48 hours after injection, infection requiring antibiotic therapy, cervical laceration or fistula, and uterine rupture. The atypical dilatation and effacement of the cervix occurring with PGF2alpha-induced contractions may possibly lead to cervical incompetence with later pregnancies. Although the efficacy of PGF2alpha as an abortifacient is confirmed, the large complication rate with the procedure cannot be ignored.
