Preparing for instrumental birth

Overview

Instrumental birth is when a healthcare professional uses special tools—either forceps (like large spoons) or a vacuum (a soft cup with suction)—to help guide your baby out of the birth canal during labour. It is sometimes called an assisted vaginal birth and is done to keep you and your baby safe when you need a little extra help to deliver.

Yes, around one in eight first-time mothers in the UK have an instrumental birth. It is less common in women who have given birth before.

Instrumental birth is used for women who are in the final stage of labour (pushing stage) and need assistance. It may be recommended if you are exhausted, the baby is showing signs of distress, or your health is at risk.

Symptoms

Causes

Main causes

• Labour is not progressing – the mother is pushing but the baby is not moving down
• The baby shows signs of distress on the heart monitor
• The mother is too tired or has a medical condition (e.g., heart problem) that makes pushing unsafe
• The baby is in an awkward position (e.g., back-to-back or face-up)

Risk factors

• First pregnancy

When to see a doctor

See a doctor urgently if:

• If you are in labour and feel you are not making progress and are very tired
• If you notice your baby’s movements have decreased significantly
• If you have heavy bleeding or severe pain that is not normal for contractions

Book a routine appointment if:

• During antenatal appointments, ask your midwife or doctor about the possibility of an instrumental birth and what to expect
• If you have any worries about labour or birth options, speak to your maternity team

Diagnosis

The decision to use instruments is made during labour by your midwife or doctor. They will check the position of your baby, how far down they are, and how well you and your baby are coping.

Tests that may be done

• Continuous electronic fetal monitoring to check baby’s heart rate
• Vaginal examination to see how far the baby has descended and their position
• Assessment of your contractions and your effort pushing

What to expect at your appointment

You will be told why an instrumental birth is being considered. Your doctor or midwife will explain the procedure, the risks, and benefits. You will be asked for your verbal consent. You may be moved to the operating theatre in case a caesarean becomes needed. Pain relief will be given, usually an epidural or spinal anaesthetic. Then the doctor will use forceps or a vacuum to help guide your baby out during a contraction. It usually takes a few pushes.

Treatment

Preparing for an instrumental birth involves knowing what will happen, having pain relief in place, and making sure you and your baby are monitored closely. The treatment is the procedure itself, performed by an experienced obstetrician or midwife.

Self-care at home

• Learn about instrumental birth in advance – ask your midwife for information or attend antenatal classes
• Discuss your preferences with your birth partner and write a birth plan, but be flexible
• If you have time, practice breathing and relaxation techniques to stay calm
• During labour, trust your team and ask questions if you are unsure

Medical treatments

Pain relief is given before the procedure – usually an epidural, spinal block, or local anaesthetic. Sometimes gas and air or a pudendal nerve block (injection around the vagina) may be used. The doctor may make a small cut in the perineum (episiotomy) to make more space. After the baby is born, you may need stitches if you had a cut or tear. You will be offered medications to help with pain and swelling afterwards, but specific drugs are not named here.

Living with this condition

After an instrumental birth, you will stay in hospital for at least 24 hours, sometimes longer. You will be monitored for bleeding and your baby will be checked. You may have stitches that take a few weeks to heal. Rest as much as possible.

Lifestyle tips

• Avoid heavy lifting or strenuous exercise for a few weeks
• Use cushions when sitting to ease pressure on the perineum
• Keep the area clean and dry, and change maternity pads regularly
• Have your partner or family help with household tasks and baby care

Diet and exercise

Eat a balanced diet with plenty of fibre to prevent constipation, which can strain your stitches. Drink lots of water. Gentle walking is fine once you feel ready, but avoid running or abdominal exercises until your doctor says it is safe – usually after 6 weeks.

Prevention

It is not always possible to prevent the need for an instrumental birth because it depends on many factors during labour. However, staying calm, moving around in early labour, and having good pain relief may help. Choosing a water birth or upright positions may reduce the chance, but not eliminate it.

Complications

If left untreated

• Prolonged labour could cause infection or heavy bleeding
• The baby could become more distressed, leading to oxygen shortage
• Injury to the mother’s pelvic floor, bladder, or bowel if instruments are used incorrectly (rare with skilled staff)

Long-term outlook

With proper medical care, most instrumental births have good outcomes for both mother and baby. Minor effects like bruising or swelling on the baby’s head usually fade in a few days. For the mother, the perineum may ache for a while, but full recovery is usual within 6 weeks. Even if a caesarean is needed later, you and your baby will be okay. Your healthcare team will support you every step of the way.
