What is mechanical induction of labour?

A clinician may place a balloon catheter through the cervix. The balloon applies gentle pressure and can help the cervix become thinner and more open. A membrane sweep is another physical option: a clinician separates the membranes near the cervix during an examination. It may cause cramping or light bleeding and does not always start labour.

The choice depends on your pregnancy history, cervical findings, baby’s position, wellbeing, and why birth is being recommended. If the cervix becomes ready, contractions may begin naturally or medicines such as oxytocin may be discussed. A plan may change if you or the baby needs faster birth, including consideration of caesarean section.

Ask where the procedure will happen, how the cervix will be assessed, and what discomfort or cramping is expected. Bring your maternity notes, arrange transport, and ask how long you may remain at home or in hospital between checks. Tell the team about previous caesarean birth, allergies, bleeding, fluid leakage, or regular contractions before the procedure begins.

Contact your maternity unit urgently for heavy bleeding, severe constant abdominal pain, fever, fluid leakage with an unusual colour or smell, reduced fetal movement, or contractions that are regular and difficult to manage. Seek emergency help if you feel faint or seriously unwell. Symptoms of pre-eclampsia, such as severe headache, visual change, or pain beneath the ribs, also need prompt assessment.

Ask why induction is recommended, which mechanical method is suitable, what happens if it does not work, and how your baby will be monitored. Ask when misoprostol or oxytocin might be considered, what pain relief is available, and what circumstances would lead to caesarean birth.
