Balloon catheter for induction of labour

A clinician passes a thin tube through the cervix and fills a small balloon with sterile fluid. It is one possible first stage of induction and does not always start contractions by itself. Further steps may include breaking the waters or giving medicine to stimulate contractions.

Before insertion, the maternity team reviews why induction is advised, checks the baby's position and wellbeing, and assesses the cervix. A speculum or vaginal examination may be used to guide placement. Insertion can cause pressure, cramping, or discomfort, and a small amount of spotting can follow.

The tube may be secured to the thigh and the balloon is left to apply pressure. It can fall out when the cervix opens. Timing, monitoring, movement, eating, and whether you can leave the unit depend on local practice, the reason for induction, and the health of you and your baby.

Ask the team what you may eat or drink, which regular medicines to take, and what comfort choices are available. Slow breathing, changing position when permitted, emptying your bladder, and using approved pain relief may make cramping easier to manage.

Do not pull or adjust the tube. Tell staff when contractions begin, waters break, bleeding occurs, or the device comes out. Induction can take time and the next step is guided by cervical change and monitoring, so ask when reassessment is planned and what options would follow if the cervix remains closed.

Contact staff immediately for reduced or changed baby movements, heavy or fresh bleeding, severe constant abdominal pain, breathing difficulty, collapse, fever, or fluid that is green, brown, foul-smelling, or accompanied by concern. Do the same if contractions feel very frequent or you have a strong urge to push.

If you are allowed home with the balloon, use the contact instructions supplied by your maternity unit rather than waiting for the next appointment when a warning sign appears. Call as directed if your waters break, labour starts, the balloon drops out, or you become worried about your own or your baby's wellbeing.

Ask why induction is being recommended now, why a balloon is suitable, how you and the baby will be monitored, what pain relief is available, and what happens after removal. Discuss alternatives, including what waiting longer or choosing a caesarean birth could mean in your situation.
