What should you know about unmedicated VBAC?

VBAC describes the mode of birth, while unmedicated describes your intended approach to pain relief. You can discuss movement, breathing, massage, position changes, a birth pool where available, warm water, and continuous emotional support. Choosing an unmedicated plan does not prevent you from changing your mind if labour becomes difficult or circumstances change.

Before labour, the maternity team reviews why the earlier caesarean was performed, the type of uterine incision, any other uterine surgery, the current pregnancy, and the facilities available for urgent assessment. The previous operation record can be useful because the skin scar does not always show the uterine incision.

Make a flexible birth plan with your obstetrician or midwife. Include preferred comfort measures, who will support you, how you want updates explained, and what would make you reconsider medication or a caesarean. Practise slow breathing, relaxation, upright positions, and pelvic movement before labour; ask which techniques are practical in your chosen birth setting.

During labour, the team may recommend continuous monitoring of the baby and regular assessment of your contractions, pain pattern, pulse, blood pressure, and temperature. Tell staff promptly about new or unusual pain, bleeding, dizziness, breathlessness, or a sudden change in how you feel.

Contact your maternity unit urgently for heavy vaginal bleeding, severe or constant abdominal pain, faintness, trouble breathing, fever, reduced or changed fetal movement, or fluid loss with concerning colour or smell. During labour, sudden persistent pain between contractions, a change in the contraction pattern, or an abnormal fetal heart-rate assessment needs immediate review. Do not wait for the symptoms to settle or rely on the birth plan to decide whether help is needed.

Ask whether the previous uterine incision and your current pregnancy are suitable for a VBAC discussion, what monitoring will be used, which comfort measures are available, and how quickly the team can respond if the plan changes. Clarify when to come to hospital, who can accompany you, and how your preferences will be recorded.
