Mifepristone and misoprostol for cervical ripening in surgical abortion between 12 and 14 weeks of gestation: a randomized controlled trial

No. 360-Induced Abortion: Surgical Abortion and Second Trimester Medical Methods

OBJECTIVE

This guideline reviews evidence relating to the provision of surgical induced abortion (IA) and second trimester medical abortion, including pre- and post-procedural care.

INTENDED USERS

Gynaecologists, family physicians, nurses, midwives, residents, and other health care providers who currently or intend to provide and/or teach IAs.

TARGET POPULATION

Women with an unintended or abnormal first or second trimester pregnancy.

EVIDENCE

PubMed, Medline, and the Cochrane Database were searched using the key words: first-trimester surgical abortion, second-trimester surgical abortion, second-trimester medical abortion, dilation and evacuation, induction abortion, feticide, cervical preparation, cervical dilation, abortion complications. Results were restricted to English or French systematic reviews, randomized controlled trials, clinical trials, and observational studies published from 1979 to July 2017. National and international clinical practice guidelines were consulted for review. Grey literature was not searched.

VALUES

The quality of evidence in this document was rated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology framework. The summary of findings is available upon request.

BENEFITS, HARMS, AND/OR COSTS

IA is safe and effective. The benefits of IA outweigh the potential harms or costs. No new direct harms or costs identified with these guidelines.

Cervical preparation prior to surgical abortion in real-life conditions and factors driving the prescription: A national observational study

INTRODUCTION

Few data exist to document the real-life practices regarding surgical abortion for first trimester abortion, in particular regarding the cervical preparation. Using a large national sample of French hospitals practicing surgical abortion, we explore actual practices and described drugs used for cervical preparation and factors that influence the prescription.

METHODS

From December 2013 to July 2014, a longitudinal, prospective, multicenter, non-interventional study was undertaken with the main objective of assessing in real-life conditions the modalities of cervical preparation prior surgical abortion in women with less than 14 weeks of amenorrhea.

RESULTS

A total of 542 patients agreed to participate and were included by 36 French private or public hospitals. Among 36 active centers, 31 (86.1%) implemented cervical preparation prior surgical abortion, in line with French and international clinical guidelines. For the 510 patients who underwent surgical abortions, the most frequent prescribed treatment was misoprostol only (224/510, 43.9% of patients), following by mifepristone only (167/510, 32.8%) and a combination of misoprostol and mifepristone (99/510, 19.4%). Finally, four factors were identified as independent contributor to guide the treatment prescribed for cervical preparation: woman work situation, gestational age intensity of center's activity regarding the number of abortions yearly and mode of anesthesia.

CONCLUSIONS

Our study showed an almost systematic implementation of cervical preparation before surgical abortion in France. Misoprostol only was the most commonly prescribed treatment for the cervix preparation, followed by mifepristone only. Several factors may have a significant influence on the type of cervical preparation chosen by physicians.

Different routes of misoprostol for cervical priming in first trimester surgical abortions: a randomized blind trial

PURPOSE

To compare effectiveness and patient satisfaction of different routes of misoprostol for short-term (same day) cervical priming in first trimester surgical abortions.

METHODS

In a blind randomized trial, patients undergoing surgical abortion at a gestational age of 6 + 0-14 + 6 were administered oral, vaginal, or sub-lingual 400 mcg misoprostol, 1.5 to 4 h prior to procedure. Surgeons blinded to patient allocation evaluated cervical priming. The primary outcome was initial cervical dilatation. Secondary outcomes were cervical consistency, ease of dilation, patient discomfort, and side effects.

RESULTS

From July 2015 through May 2016, 120 patients were randomized as follows: 40 to oral, 40 to vaginal, and 40 to sublingual misoprostol administration. No differences were noted in patient age, gestational age, curettage indication (termination/delayed miscarriage), past vaginal delivery, and administration to procedure interval. Initial cervical dilatation was similar between the groups, as were cervical consistency and ease of dilation. Patients noted the greatest discomfort and side effects with sublingual administration. The followings were found to be independently associated with cervical dilatation in a linear regression analysis: sublingual administration, gestational age, missed abortion, and previous vaginal delivery. Side effects and administration to procedure interval were found non-significant.

CONCLUSION

The same day cervical priming for first trimester surgical abortion is similarly achieved with all routes of misoprostol administration. In cases of termination of pregnancy with no prior vaginal delivery, sublingual administration may be considered, but entails a higher rate of side effects and patient discomfort.
