Laminaria and sulprostone in second trimester pregnancy termination for fetal abnormalities

The efficacy and safety of intracervical placement of laminaria and intravenous prostaglandin E2 (sulprostone) infusion for termination of second-trimester pregnancies with abnormal fetuses was investigated. One hundred and six pregnant women at 13-29 weeks' gestation with fetal anomalies underwent laminaria tent insertion into the cervical canal on admission. The next morning, Sulprostone infusion was started at a rate of 16 microg/h and increased by 16 microg/h every 30 min to induce uterine contractions. Induction-to-abortion time (IAT), success and complete abortion rates, and sulprostone-related side effects were registered. The overall success and complete abortion rates within 24 h were 91.5 and 80.2%, respectively. The mean IAT was 12.1+/-7.6 h. The incidence of nausea and/or vomiting was 17.9%, with 1.7 episodes per case. Diarrhea and fever (9.5%) were not common. Laminaria tent insertion plus sulprostone infusion was an effective and safe regimen for second-trimester termination of pregnancy with live fetuses.
