Epidural Information Card

Epidural Information Card

This is a summary. There is fuller information in the Pain Relief in Labour section.   Please discuss anything that is not clear with your anaesthetist.

Setting up your epidural

  • You will need to have an intravenous cannula and maybe a drip.
  • While the epidural injection is being put in, it is important that you keep still and let the anaesthetist know if you are having a contraction.
  • Usually takes 20 minutes to set up and 20 minutes to work.
  • Some epidurals do not work fully and need to be adjusted or replaced.

Advantages of an epidural

  • Usually provides excellent pain relief.
  • Sometimes a spinal is given first for a quicker effect.
  • The dose or type of local anaesthetic can sometimes be altered to allow you to move around the bed. This is a low-dose (or mobile) epidural.
  • In general epidurals do not affect your baby.
  • Can be topped up for caesarean section if required.

Possible problems with your epidural

  • Repeated top-ups with stronger local anaesthetic may cause temporary leg weakness and increase the risk of forceps or ventouse delivery.
  • The epidural may slow down the second stage of labour slightly.
  • You may develop low blood pressure, itching or a fever during the epidural.
  • The epidural site may be tender but usually only for a few days. Backache is NOT caused by epidurals but is common after any pregnancy.
