Episiotomy

An episiotomy is an incision made in the perineum (the tissue between the vaginal opening and the anus) and vagina to enlarge the vaginal opening (RCOG 2015). This indicator examines the frequency of episiotomy for women having their first baby and giving birth vaginally, either with or without the assistance of instruments. For more information, see Clinical commentary.

Key findings

  • In 2021, nearly one quarter of women (23%) giving birth for the first time received an episiotomy in a non-instrumental vaginal birth.
  • In 2021, around 4 in 5 women (81%) giving birth for the first time received an episiotomy in an instrumental vaginal birth.
  • The proportion of women giving birth for the first time receiving an episiotomy has increased from 16% in 2004 to 23% in 2021 for non-instrumental vaginal births.
  • The proportion of women giving birth for the first time receiving an episiotomy has increased from 61% in 2004 to 81% in 2021 for instrumental vaginal births.

Figure 10: Episiotomy

Episiotomy for women having their first baby and giving birth vaginally (instrumental), 2004 to 2021.

This chart shows the proportion of women having their first baby with an episiotomy and giving birth vaginally assisted (with instruments), for the current data 2021 and trend data from 2004 to 2021. The proportion of women giving birth for the first time, vaginally assisted (with instruments) who had an episiotomy increased from 61% in 2004 to 81% in 2021. The chart also shows the proportion of women giving birth for the first time, vaginally without the use of instruments who had an episiotomy. This has increased from 16% in 2004 to 23% in 2021.

Clinical commentary

Episiotomy can shorten the second stage of labour, but the consequences of the trauma to the perineum and, potentially to the anus and rectum, need to be balanced against the need for episiotomy. The possible use of episiotomy during a vaginal birth must be discussed prospectively with the woman (ACSQHC 2021).

Evidence suggests that selective use of episiotomy is better practice than routine use of episiotomy and may reduce the level of pain, urinary incontinence, painful sex or severe perineal trauma (Jiang et al. 2017).
