Membrane Sweep: What is it?

What’s a membrane sweep?

A membrane sweep or membrane stripping is a type of intervention that does not rely on medication.  This  intervention is done by your provider with your permission. Your provider will take a gloved hand, insert their finger into the vagina and through the cervical opening. You can expect this to feel like a repeated sweeping motion to separate the membranes of the amniotic sac away from the bottom part of the uterus.

What happens when we do a membrane sweep?

When your provider performs a membrane sweep, the goal of this intervention is to trigger the release of prostaglandins. This hormone release is in charge of causing the cervix to soften and ripen. Prostaglandins also aid in helping the uterus to contract. 

What if the cervix has no change prior to the membrane sweep?

In the event your provider finds the cervix to be completely closed, they may massage the cervix. This technique helps the body to release hormones that are beneficial in helping the body move toward labor.

What are the benefits and risks of a membrane sweep?

The benefit of a membrane sweep is that it may bring on labor, and may also help the patient to avoid potential medicinal interventions. As with any intervention, there is always inherent risk. This method can feel painful and uncomfortable to the person having it done. There is potential for accidental rupture of membranes, and the possibility of labor not starting at all. Some report that they experience contractions that are irregular in nature. 

Should I get my membranes swept?

You have options when it comes to this form of induction/intervention: choosing the sweep, choosing to allow labor to start on its own, or opting to have repeat sweeps done. Discuss with your provider your options and decide what feels best for you.
