Anaesthesia is used to relieve pain during a caesarean section or instrumental vaginal birth. All women who have a caesarean section receive anaesthesia, except in the rare case of post-mortem delivery. More than one type of anaesthetic can be administered.

In 2020, most mothers who had a caesarean section had a regional anaesthetic (69% spinal, 19% epidural or caudal; noting that some mothers had both) and 5.3% had a general anaesthetic.

The data visualisation below presents data on the anaesthesia administration status of women who gave birth and had a caesarean section or instrumental vaginal birth, by selected maternal characteristics, for 2020.

The figure shows a bar chart of women who had an instrumental vaginal birth or caesarean section by anaesthesia administration status and a range of topics for 2020. The figure also shows a line graph of the trends of anaesthesia administration by topics between 2010 and 2020. In 2020, 141,706 women, or 97%, who had an operative delivery had anaesthesia.

Most mothers who had an instrumental vaginal birth had an anaesthetic. A regional anaesthetic was most common (67% epidural or caudal and 3.6% spinal), followed by a local anaesthetic to the perineum (22%).

Women who had a vaginal instrumental birth using forceps (95%) were more likely to have anaesthesia administered than women who had a vacuum extraction (88%).
