However, as most pregnancies will not go past 42 weeks anyway this information has limited significance for the average expectant woman. If done at each appointment from 38 weeks on, membrane sweeping was shown to slightly reduce the number of pregnancies that go past 41 and 42 weeks. Studies do show that having the membranes swept can create clinically significant results. The agitation of this area and manipulation of the membranes may cause the body to increase production of prostaglandins, ie the hormones that are thought to ripen the cervix in preparation for labor. A finger is placed into the cervix, then in technical terms, “the inferior pole of the membranes is detached from the lower uterine segment by a circular movement of the examining finger”.* In lay terms that means that a finger is placed through the cervix and separates the membranes of the amniotic sac from the bottom part of the uterus, lifts it up a bit and a finger is run around the exposed diameter. Sweeping of the membranes, also called stripping or stretching, is a procedure performed during a vaginal exam. What does SOGC (Society of Obstetricians and Gynaecologists of Canada) recommend? The SOGC recommends that women should be offered the option of membrane sweeping commencing at 38 to 41 weeks, following a discussion of risks and benefits.Sweeping, stretching and stripping all sound a bit scary, after all one’s lower uterus is not used to getting much action.

A study by Avdiyovski, Haith-cooper & Scally demonstrated membrane sweeping is effective in promoting a spontaneous labour and thereby reducing the need for formal induction.

Research suggests that pregnancy exceeding 42 weeks gestation is associated with an increased risk of perinatal morbidity and mortality.

In another study, both the induction-to-labour interval and oxytocin use were decreased, and there was an increased rate of normal vaginal delivery.

A well-designed Canadian study enrolled patients at 38 to 40 weeks, and did not find any differences between a single membrane sweeping and routine examination with respect to onset of after 41 weeks or need for induction of labour.

Time to delivery was significantly decreased with membrane stripping, and there were fewer pregnancies reaching past 41+0 weeks.

In a study by Berghella et al.,45 patients were randomized to weekly sweeping of membranes or gentle exams starting at 38 weeks.

Eight women would need to undergo sweeping of membranes to prevent one induction of labour.

Sweeping of the membranes at term (38–41 weeks) reduced the frequency of pregnancies continuing after 41+0 weeks. A recent Cochrane review assessed 22 trials involving sweeping membranes.Multiple studies have established membrane sweeping as a safe practice that does not increase maternal or fetal morbidity or mortality. Potential increased incidence of prelabour rupture of membranes (mixed studies).Bleeding from an undiagnosed previa, rare as it is usually diagnosed by ultrasound.Unintentional rupture of membranes (water breaking), rare.May decrease the need for formal induction at 41 weeks gestation In some trials, membrane sweeping has been an effective outpatient method for reducing pregnancies that go beyond 41 Plasma prostaglandins levels after a membrane sweep are 10% of those achieved with labour therefore possibly improving labour outcomesĬan be beneficial for first time mamas with an unfavourable Bishop score (Tool used by clinicians to determine cervical status)
