2026-04-01
An assisted vaginal birth is when your doctor uses a forceps or ventouse (vacuum cup) to help deliver your baby.
About 1 in 7 women in Ireland has an assisted birth.
Your doctor will only use these tools if they feel it is the safest way for you to give birth.
An assisted birth is sometimes called an instrumental delivery.
Indications for Operative Vaginal Delivery
Prolonged second stage of labor.
Suspicion of immediate or potential fetal compromise.
Shortening of the second stage of labor for maternal benefit (e.g., cardiac, neurologic, or lung disease).
Why you might need an assisted birth?
An assisted birth speeds up the delivery of your baby.
You might need an assisted birth if your baby is:
1.getting distressed or there is a concern about their heartbeat.
2.not moving out of your birth canal as expected.
3. in an awkward position.
Your doctor or midwife may also feel it's necessary if:
1.you are unable to push because of a medical condition.
2.you are getting exhausted.
3.your contractions have become less intense.
Vacuum-Assisted Vaginal Delivery
Vacuum-assisted delivery has risen in popularity largely due to a belief that it is easier to learn. It is generally less traumatic for the mother than forceps-assisted delivery. However, it still carries a risk of neonatal complications and should only be used by skilled providers. It is more likely to fail than forceps-assisted delivery. Use of vacuum under 34 weeks of gestation or in small fetuses is discouraged.
