The studies took place all over the world, including many studies in the United States, but also there were studies from India, Thailand, Nigeria, the United Kingdom, Canada, and many other countries.
This is called parity. Some of the studies had only first-time parents. Others included only multiparous people, meaning that these were parents who were having a subsequent baby. But most studies had mixed parity, meaning that they had both first-time parents and multiparous people in the study.
The gestational age at which membrane sweeping was performed was different in the studies as well. A few studies looked at membrane sweeping starting at 36 or 37 weeks, but most did not perform membrane sweeping until at least 38 weeks and many waited until 40 weeks.
About half of the studies took place in the s and the other half took place in the 21st century. For the most part, the Cochrane reviewers judged that the studies that they included were either at low risk or unclear risk for bias.
However, in general, there was a high risk of bias for performance bias due to the fact that all 44 studies did not do any masking in the study. This is sometimes called blinding. Masking would mean that clinicians and researchers did not know who was receiving which treatment, either the actual treatment or the no treatment or the placebo or sham. When no masking is used, as with all of these studies, this may lead to performance bias in which clinicians may be biased towards giving better care to the treatment group in hopes that the treatment will be shown to be effective.
For example, if a provider knew someone was in the treatment group for membrane sweeping, they might delay scheduling a formal induction in hopes that the person in the treatment group will go into spontaneous labor on their own. But there are some steps you could take. But unfortunately in all of these studies, everybody knew who was in the treatment group and who was not in the treatment group.
The remaining four studies compared membrane sweeping with other medications. The combined data from these trials show that pregnant people who were assigned to membrane sweeping, or cervical massage if the cervix was closed, were on average more likely to have labor start on its own instead of with a formal induction.
These findings appear to apply equally to first-time parents and to those who had given birth before. They found that people in the membrane sweeping group were less likely to have an induction.
Post-term pregnancy is the most common reason for induction, so membrane sweeping could potentially reduce inductions for post-term pregnancy. However, the author said that these findings should be interpreted with caution because the evidence is low certainty.
And again, these findings appear to apply equally to first-time parents and to those who have given birth before. When the Cochrane reviewers looked at other outcomes, they found no differences between the groups in the rate of cesareans, the use of forceps or vacuum to assist with the delivery, or serious illness or death for mothers or babies. There is less data on whether or not membrane sweeping or cervical massage can help ripen the cervix or soften the cervix.
Only one participant assigned to membrane sweeping was not able to complete the procedure because of a closed cervix. Both the cervical massage and the membrane sweeping groups were linked to a significant increase in the average Bishop score 48 hours after the treatment compared to the control group.
This is evidence that cervical massage may be an effective alternative to membrane sweeping and could be offered to pregnant people with a closed cervix. What about satisfaction? Sadly, only three of the 44 studies in the Cochrane review looked at maternal satisfaction with membrane sweeping.
In those three randomized trials that looked at satisfaction, there were pregnant people in those studies. The majority of participants reported a positive experience with membrane sweeping. However, very few studies have included maternal satisfaction or pain as an outcome. I have corresponded with many people around the world who had membrane sweeping done without their permission or consent and they usually describe it as a particularly painful vaginal exam.
It may be that choice plays a role in the matter and that people who choose with informed consent to have membrane sweeping may have less pain than those who have it done forcibly upon them. However, we have zero research on the subject of forced or non-consented membrane sweeping. Another strategy that some people who do not want to have membrane sweeping use to avoid membrane sweeping is to simply decline all vaginal exams towards the end of pregnancy.
But in fact, membrane sweeping is a medical procedure that requires informed consent. So what are the advantages of having membrane sweeping?
