Membrane stripping, also known as a cervical sweep, is a common method used to encourage the onset of labor. This procedure involves a manual separation of membranes within the cervix, performed by a healthcare provider. This article provides information about the process, what to expect, potential outcomes, and when it may not be suitable.
Understanding Membrane Stripping
Membrane stripping involves a healthcare provider inserting a gloved finger into the cervix to gently separate the amniotic sac from the lower part of the uterus. This action stimulates the release of prostaglandins, hormone-like compounds that soften, thin, and dilate the cervix, preparing it for labor. Healthcare providers may suggest this procedure to initiate labor without medication, especially if a pregnancy is nearing or has passed its estimated due date. It is typically offered around 39 to 40 weeks when the cervix has begun to dilate.
The Procedure: What to Expect
The membrane stripping procedure is performed during a routine office visit and typically takes only a few minutes. You will be positioned on an exam table with your feet in stirrups, similar to a standard pelvic examination. The healthcare provider will first assess the cervix to determine if it is sufficiently dilated.
If the cervix is favorable, the provider inserts one or two gloved fingers and uses a circular motion to sweep around the opening, separating the amniotic sac from the uterine wall. While the procedure is brief, you may experience discomfort, pressure, or mild cramping. Some describe the sensation as similar to a rough pelvic examination.
Potential Risks and Side Effects
Membrane stripping is considered a low-risk procedure for individuals with uncomplicated pregnancies. Common side effects after the procedure include cramping, which might last for up to 24 hours, and light vaginal bleeding or spotting. Some also experience irregular contractions that may not progress into active labor.
Less common risks include accidental rupture of membranes (water breaking). While this can occur, it is generally not a concern in full-term pregnancies. Severe pain or heavy bleeding are not typical and should prompt immediate contact with a healthcare provider.
What Happens After Membrane Stripping?
After membrane stripping, you can typically return home to await the onset of labor. Many experience cramping and light spotting, which are normal responses. If the procedure is successful, labor often begins within 24 to 48 hours, though this timeframe can vary.
Signs of labor to watch for include regular, intensifying contractions, increased vaginal discharge, or the rupture of membranes. If labor does not begin within a few days, the procedure can sometimes be repeated, or other induction methods may be discussed with your healthcare provider.
When Is It Not Recommended?
Membrane stripping is not suitable for everyone. Healthcare providers advise against the procedure if conditions make a vaginal delivery unsafe, such as placenta previa where the placenta covers the cervix.
It is also not recommended with an active genital herpes infection, a current bacterial cervical infection, concerns about the baby’s position, or certain fetal abnormalities. A thorough medical evaluation by a healthcare provider is always conducted to ensure the procedure’s appropriateness and safety.
