Assisted vaginal birth (ventouse or forceps)

Published: 29/04/2020

This information is for you if you wish to know more about assisted vaginal birth (also known as operative vaginal birth). An assisted vaginal birth is when a healthcare professional uses specially designed instruments to help you give birth to your baby.

You may choose to read this information whilst you are pregnant to help with planning your birth.

This information may also be helpful if you are a partner, relative or friend of someone who is in this situation.

Please see here for the latest information on coronavirus infection for pregnant women and their families.

The information here aims to help you better understand your health and your options for treatment and care. Your healthcare team is there to support you in making decisions that are right for you. They can help by discussing your situation with you and answering your questions.

This information covers:

  • What an assisted vaginal birth is
  • Why you might need an assisted vaginal birth
  • What happens during an assisted vaginal birth
  • What forceps and ventouse births are
  • What an assisted vaginal birth means for you and for your baby

You can see a full glossary of all medical terms.

 

Key points

  • In the UK, approximately 1 in 8 women have an assisted vaginal birth and this is more likely (1 in 3) for women having their first baby.
  • Assisted vaginal birth includes birth helped by use of a ventouse (vacuum cup) or forceps or both. Your healthcare professional will discuss the benefits and risks of assisted vaginal birth with you.
  • The majority of babies born this way are well at birth and do not have any long  term  problems.
  • Having an assisted vaginal birth does not mean you will need one in your next pregnancy

Why might I need help with the birth of my baby?

There can be many reasons for needing help with the birth of your baby. The main ones are:

  • there are concerns about your baby’s wellbeing during birth
  • your labour is not progressing as would usually be expected
  • you are unable to, or have been advised not to, push during birth

 

How common is an assisted vaginal birth?

Overall about 1 in 8 (10-15%) births in the UK will be an assisted vaginal birth although this is much less common in women who have had a vaginal birth before. 1 in 3 women having their first baby will have an assisted vaginal birth. Your healthcare professional will discuss ways to reduce your chance of needing an assisted vaginal birth during your pregnancy.

 

Can I avoid an assisted vaginal birth?

If you have someone supporting you throughout your labour, you are less likely to need an assisted vaginal birth, particularly if the support comes from someone you know, in addition to your healthcare professional. 

Assisted vaginal births are less likely if you do not have any complications in your pregnancy and plan to have your baby in a midwife-led unit.  Using upright positions or lying on your side after your cervix is fully open in labour can reduce the need for an assisted vaginal birth.  Having an epidural for pain relief in labour may increase the chance of you needing an assisted vaginal birth, but this is less likely with modern epidural anaesthetics.

The need for an assisted vaginal birth may be reduced by not starting to push too soon after your cervix is fully open.  You may be advised to wait until you have a strong urge to push, or to try and delay pushing by 1-2 hours depending on your individual situation.

 

What is a ventouse birth?

A ventouse (vacuum cup) is an instrument that uses suction to attach a plastic or metal cup on to your baby’s head. Your healthcare professional will wait until you are having a contraction and then ask you to push while they pull to help you give birth. This may happen over several contractions. Sometimes the cup can detach itself, making a “pop” sound.  If this happens your healthcare professional may need to re-apply the cup to your baby's head before continuing.

What is a forceps birth?

Forceps are smooth, curved metal instruments. They are made to carefully fit around your baby’s head. Your healthcare professional will wait until you have a contraction and then ask you to push while they pull with the forceps to help you give birth. This may happen over several contractions.

Do I have a choice between ventouse and forceps?

Ventouse and forceps are both safe and effective. Choice of instrument depends on factors including how well your epidural is working (if you have had one), the wellbeing of your baby and the position of your baby’s head.  If you need an assisted vaginal birth at less than 36 weeks of pregnancy, forceps may be preferred over ventouse. This is because they involve less risk of injury to your baby’s head which is softer at this stage of pregnancy.

Your healthcare professional will recommend the method most suitable for your individual situation. If you have any concerns around the use of ventouse or forceps you should discuss this with your healthcare professional at any time during your pregnancy or labour.

If one instrument has been chosen and is not effective, your healthcare professional may then either recommend using the other instrument to help you have a vaginal birth or offer a caesarean, depending on your individual circumstances.  

If neither instrument is effective in helping you give birth, your healthcare professional will recommend an emergency caesarean birth.

 

What are my alternatives to assisted vaginal birth?

Forceps and ventouse will only be recommended if they are thought to be the safest way to help you give birth. The reasons for recommending an assisted vaginal birth, the choice of instrument and the procedure will be discussed with you at the time. If you are in labour and choose not to have an assisted vaginal birth, the alternatives are to wait for your baby to be born without assistance or to have an emergency caesarean. Your healthcare professional will discuss your options depending on your individual circumstances.

A caesarean in the late stage of labour is a more complex operation than a planned caesarean and in some circumstances may increase the risk of harm to both you and your baby.  

Decision making in labour can be difficult which is why it is important to explore any concerns you may have with your healthcare professional before you go into labour.

If you are certain you would not want an assisted vaginal birth, one option is to choose a planned caesarean birth before you go into labour. If you are considering a planned caesarean you should discuss this with your healthcare professional during your pregnancy. For more information, refer to the RCOG patient information on caesarean birth.

 

What happens during a forceps or ventouse assisted vaginal birth?

With your consent, your healthcare professional will examine your abdomen and perform an internal examination to confirm that an assisted vaginal birth is safe for you and your baby. You will usually be asked to sit with your legs supported and your bladder will be emptied by passing a small tube (catheter) into it.

Pain relief for the birth may be either a local anaesthetic injection inside the vagina or a regional anaesthetic injection into your back (an epidural or a spinal). For more information about pain relief during labour see the Labour Pains website (labourpains.com) from the Obstetric Anaesthetists’ Association.

You are more likely to need to have a cut (episiotomy) to enlarge your vaginal opening and allow your baby to be born. 

A healthcare professional who specialises in the care of newborn babies may be there when you give birth in case your baby needs some extra help after birth. If your baby is well you may choose to have immediate skin to skin contact and/or delayed cord clamping.

After your baby is born you will be given some antibiotics through a drip to reduce the chance of you developing an infection.

 

Where will my baby be born?

If your healthcare professional expects your assisted vaginal birth to be straightforward, they will recommend that you give birth in the same room where you have been in labour. If they think that the assisted vaginal birth may be more complicated or that there is a chance that it might not work, you will be advised to give birth in the operating theatre. This is so that you can have an immediate caesarean if necessary.

 

What makes an assisted vaginal birth less likely to be successful?

Assisted vaginal birth is less likely to be successful if:

  • you are overweight with a body mass index (BMI) over 30;
  • you are less than 161cm in height
  • your baby is estimated to be more than 4kg in weight
  • your baby is lying with its back to your back at the end of your labour
  • your baby’s head is not low down in the birth canal at the end of your labour

 

What will an assisted vaginal birth mean for me?

You may need to stay in hospital for longer than originally expected after the birth of your baby.

Bleeding

It is normal to have vaginal bleeding after you have given birth. Straight after an assisted vaginal birth, heavier bleeding is more common. The bleeding in the days afterwards should be similar to an unassisted vaginal birth.

Vaginal tears/ episiotomy

Birth with ventouse and with forceps does mean a higher chance of you needing to have an episiotomy or having a vaginal tear. If you have either a vaginal tear or an episiotomy, this will be repaired straight after birth with dissolvable stitches. For further information see www.rcog.org.uk/tears.

A third- or fourth-degree tear (a tear which involves the muscle and/or the wall of the anus or rectum) affects 3 in 100 women (3%) who have a vaginal birth. It is more common following a ventouse birth, affecting up to 4 in 100 women (4%) and following a forceps birth, affecting between 8 and 12 women in every 100 (8–12%).

Further information

Further information can be found on the RCOG information hub on perineal tears (www.rcog.org.uk/tears) and in the RCOG Patient Information Care of a third- or fourth-degree tear that occured during childbirth (OASI).

Pain relief

Most women have some discomfort or pain after they have given birth. You will be offered regular pain relief after an assisted vaginal birth.

Bladder care

If you have had an assisted vaginal birth you are more likely to have difficulty passing urine after birth. If you have had an epidural, you may not be able to feel your bladder getting full and may need a catheter to help empty your bladder for a few hours until your epidural wears off.

It is important that you empty your bladder completely after birth to reduce the risk of longer term problems with passing urine. Your healthcare professional may ask you to pass urine in a jug so they can measure the amount. If they think that you haven’t been able to fully empty your bladder, they may use either an ultrasound or a catheter to check. 

Leaking urine is common in late pregnancy and after birth. Physiotherapy may help to treat symptoms of urinary incontinence. If you have any concerns, you should discuss these with your healthcare professional who can refer you to further support.

Reducing the risk of blood clots

Being pregnant increases the risk of blood clots in your legs and lungs. This risk increases after an assisted vaginal birth. You can help to reduce the chance of this happening by being as mobile as you can after your baby is born. Depending on your individual circumstances you may be offered blood thinning injections to reduce the risk of you developing clots. Further information can found in the RCOG Patient Information Reducing the risk of venous thrombosis in pregnancy and after birth.

 

What will an assisted vaginal birth mean for my baby?

Most babies born by assisted vaginal birth are well and do not have any long term problems.
The suction cup used for a ventouse birth often causes a mark on a baby’s head. This is called a chignon (pronounced sheen-yon) and usually disappears within 24–48 hours. The suction cup may also cause a bruise on a baby’s head called a cephalohaematoma. This happens in between 1 to 12 in 100 babies and it disappears with time. It rarely causes any problems for babies. Forceps marks on the baby’s face are very common. They are usually small and disappear within 24–48 hours. Small cuts on the baby’s face or scalp are also common (occurring in 1 in 10 assisted vaginal births) and heal quickly. 

Less common risks include:

  • jaundice, 5 to 15 in 100 babies
  • bleeding in baby’s brain, 5 to 15 in 10 000 babies.

Serious trauma such as fractures or damage to nerves in the baby’s face are rare.

 

Will I be able to discuss the birth before I leave hospital?

Yes. Before you go home from hospital, you should be given the chance to talk about the birth of your baby with one of your healthcare professionals, ideally someone who was there when your baby was born. They will be able to answer any questions you may have.

 

How will I feel after I leave hospital?

Most women recover well after their assisted vaginal birth. After any birth, including an assisted vaginal birth, you may have some pain. The stitches and swelling may make it painful when you go to the toilet to pass urine or open your bowels. Regular pain relief will help. 

You can begin to have sex again when you feel that it’s the right time for you.

The experience of birth can sometimes be distressing and for some women there is a risk of post-traumatic stress disorder (PTSD). Following an assisted vaginal birth, if you feel you are developing anxiety, have low mood or feel that you need additional support, you should talk to your healthcare professional.

 

Will I need an assisted vaginal birth next time?

Having an assisted vaginal birth does not mean you will need one in your next pregnancy. Most women (up to 9 in 10) who have an assisted vaginal birth have a vaginal birth next time round without needing assistance.

 

About intimate examinations

The nature of obstetrics and gynaecology care means that intimate examinations are often necessary.

We understand that for some people, particularly those who may have anxiety or who have experienced trauma, physical abuse or sexual abuse, such examinations can be very difficult.

If you feel uncomfortable, anxious or distressed at any time before, during or after an examination, please let your healthcare professional know.

If you find this difficult to talk about, you may communicate your feelings in writing.

Your healthcare professionals are there to help and they can offer alternative options and support for you.

Remember that you can always ask them to stop at any time and that you are entitled to ask for a chaperone to be present. You can also bring a friend or relative if you wish.

Shared Decision Making

If you are asked to make a choice, you may have lots of questions that you want to ask. You may also want to talk over your options with your family or friends. It can help to write a list of the questions you want answered and take it to your appointment.

Ask 3 Questions

To begin with, try to make sure you get the answers to 3 key questions, if you are asked to make a choice about your healthcare:

  1. What are my options?
  2. What are the pros and cons of each option for me?
  3. How do I get support to help me make a decision that is right for me?
