Same-day cervical preparation with misoprostol prior to second trimester D&E: a case series.

Background: Traditionally, overnight cervical preparation with osmotic dilators has been used for second trimester dilation and evacuation (D&E) procedures. Misoprostol offers an alternative treatment that could shorten cervical preparation time.

Study Design: This study reports on a case series of patients who received only buccal or vaginal misoprostol for cervical preparation on the same day as the D&E procedure. Data were collected from charts of women undergoing second trimester D&E at an outpatient women's health clinic. Eligible cases included procedures performed between January 2001 and December 2010 at 17 0/7 to 23 0/7 weeks of gestation.

Results: Chart review identified 1177 cases of D&E during the study period. After deletion of 96 multiple-day cases using laminaria, 1081 misoprostol-only cases remained for analysis. Two of the cases were not able to be completed in the same day (0.2%). Ninety-eight percent of cases were 17-20 weeks of gestation. The average time from either vaginal or buccal placement of the first misoprostol dose to procedure completion was 4.9 h (SD±1.7 h). The average procedure length was 13.0 min (SD±10.2 min). Complications were reported in 21 of 1079 same-day procedures (2%) and included resuction (n=4), hemorrhage (n=5), cervical laceration (n=4), endometritis (n=5), pulmonary embolus (n=1), disseminated intravascular coagulation (n=1) and perforation (n=1).

Conclusion: Same-day cervical preparation with misoprostol for second trimester D&E is both safe and effective. With the continuing shortage of D&E providers, the resulting increase in travel distance to obtain the procedure, mandatory waiting periods and the capability of having the procedure completed in a single day may increase patient access, reduce cost and improve patient satisfaction.
