Membrane Sweep

Although we advocate patience and avoidance of unnecessary interference during pregnancy, labour and birth, we do offer membrane sweeps at around 41 weeks.  Whilst this is an invasive procedure, it is one of the more ‘natural’ methods of encouraging labour to begin when you are nearing 42 weeks and there is no sign of baby. Studies show that this procedure increases the likelihood of going into labour naturally. It has a higher chance of working if your cervix is already softening and preparing for labour.

Membrane sweeping involves your midwife performing a special vaginal examination. She inserts a finger into the cervix and then makes a firm, circular, sweeping movement around the neck of the womb. This movement helps to separate the cervix from the membranes and hopefully stimulate the release of prostaglandins - the hormones that signal to the brain that it's time to start labour.

The extent of discomfort experienced during a sweep varies and, while some women find it absolutely fine, others experience more discomfort.  Relaxation exercises help to ease the discomfort during the examination; however the midwife will stop the procedure if you find it distressing.

A sweep will not cause any harm to your baby or increase the chance of infection. Sometimes there is slight bleeding or irregular contractions following the examination.  If you have any concerns following a membrane sweep, please don’t hesitate to contact your midwife.

It is important to note that, if you don't feel comfortable with the procedure and would prefer your baby to arrive in his or her own time, it is perfectly reasonable to decline and the midwives will support you in your choice.
