Some women are keen to avoid drugs or other medical interventions while others are happy to consider all available options. For a woman having her first baby, the experience of labour (and her reaction to it) is unpredictable.

For this reason, it is a good idea to be aware of the options for pain relief that are available and to know something about the different methods. You may have a plan for how you hope to manage your labour, but it is best to be prepared to be flexible. Research suggests that adequate preparation can help to reduce pain or at least modify the perception of pain and reduce , which can help you to better cope with labour.

There are several non-drug pain relief options: Being in good physical condition is important. Knowing what to expect during the various stages of labour can help reduce anxiety.

Breathing techniques may help you to ‘ride the waves’ of each contraction. Constant, close support from your partner (or a trusted friend or loved one) for the duration of labour can reduce anxiety. Using distractions like music can help to take your mind off the pain.

Hot or cold packs, massage, a warm shower or immersion in a warm bath, and keeping active may all be helpful. and acupressure are areas in which there has been little research but these may be considered also. TENS is a technique in which nerves in the lower back are stimulated using a small hand-held device controlled by the woman.

It has no known side effects for mother or baby and many women find it helpful either alone or in combination with other methods of pain relief. The three main medical pain-relieving options for labour include:

  • epidural anaesthesia. Nitrous oxide known as ‘laughing gas’ is mixed with oxygen
  • administered to the mother through a face mask or a tube held in the mouth

The gas takes a few seconds to work, so it is important to breathe from the mask as soon as a contraction starts. Nitrous oxide doesn’t stop the pain entirely, but takes the ‘edge’ off the intensity of each contraction. Many women prefer nitrous oxide because it allows them direct control – you can hold the mask yourself and take deep breaths whenever you feel the need.

Nitrous oxide doesn’t interfere with contractions and it doesn’t linger in either the woman’s or the baby’s body. Possible problems with using nitrous oxide include:

  • lack of pain relief – in some cases
  • nitrous oxide doesn’t offer any pain relief at all (this applies to around one-third of women). Pethidine is a strong pain reliever (related to morphine
  • heroin)
  • usually injected directly into a muscle in the buttock

It may also be administered intravenously (directly into a vein). Depending on various factors, the effect of pethidine can last anywhere from 2 to 4 hours. Pethidine can make you feel sick, so anti-nausea medications are usually administered at the same time.

Possible problems with pethidine for the mother include:

  • lack of pain relief
  • in some cases. Possible problems with pethidine for the baby include
  • The unborn baby is exposed to the drug via the umbilical cord
  • may experience respiratory depression at birth
  • particularly if several doses are given or the baby delivers soon after a pethidine injection

This effect can be reversed by an injection given to the baby.

The baby’s sucking reflex may also be depressed, as well as other normal reflexes. Debate persists over the effects of pethidine on newborns. Epidural injections are the most effective pain relief available.

They are used for vaginal births and also for caesarean sections, because they allow the mother to stay awake and alert during the baby’s birth. Anaesthetic is injected into the lining of the spinal cord through the back, which makes the mother feel numb from the waist down. Your baby’s heart rate will be monitored continuously.

Possible side effects and complications of epidural anaesthesia include:

  • The anaesthesia may not be complete
  • you may still experience some pain

This may require the procedure to be repeated

After the epidural has been inserted, your blood pressure may drop, causing you to feel faint and nauseated.

This may also cause stress to your baby

This is treated by giving intravenous fluid

An epidural often causes some muscle weakness in the legs, so women who have had an epidural anaesthetic may be confined to bed. The lack of sensation in the lower body means that you will not be able to tell when you need to urinate. A urinary catheter will be inserted in most cases.

Epidurals can lengthen the second stage of labour

The likelihood of having a normal vaginal delivery is reduced.

If you are unable to push effectively, due to altered sensation and reduced muscle strength, the baby may have to be delivered by forceps or vacuum cup. Around one per cent of women experience headache immediately following the procedure.

Some women experience itchiness after having an epidural

This can usually be effectively treated using antihistamines

Some women experience pain or tenderness where the epidural was injected. Around one in 550 women experience ongoing patches of numbness on the back near the injection site.

complications include infection, blood clots and difficulty breathing

An epidural does not: cause long-term backache
