Brief summary

The purpose of this study is to evaluate whether the use of cervical dilators for cervical ripening in case of second trimester medical termination of pregnancy (TOP) is effective to reduce duration of labor.

Detailed description

Termination of pregnancy is a distressing and painful procedure for women. The use of cervical dilators could shorten the duration of labor but can generate more pain. The investigators will compare two procedures of induction of labor for second trimester termination of pregnancy: one with the use of oral prostaglandins (misoprostol) only and one with the exact same procedure preceded by cervical ripening with hygroscopic cervical dilators. Epidural analgesia will be effective previously to the placement of cervical dilators and the first tablet of misoprostol. Efficacy will be determined based on the proportion of women achieving vaginal delivery within 12 hours. The beginning of labor will be defined as the first administration of misoprostol tablets in both groups. The investigators will also evaluate safety by collecting hemorrhage endometritis, cervical tear. The investigators will compare psychological impact of these procedures, measured by the impact of event scale and acceptability 1 to 4 months later.
