Long-term effects of neuraxial analgesia.

Purpose of review: This review article explores the potential longer-term implications of neuraxial analgesia in labour for both the mother and her child.

Recent findings: Neuraxial techniques for labour analgesia are well tolerated and effective, and long-term adverse sequelae are rare. Labour epidural analgesia is not independently associated with long-term headache, backache, postnatal depression or anal sphincter injury, and evidence supports that epidurals may offer protection against severe maternal morbidity, particularly in women at a higher risk of complications. However, there is an increasing awareness that postdural puncture headache may be associated with chronic headache, back pain and postnatal depression, emphasizing the need for adequate follow-up until symptoms resolve.For the neonate, a growing body of evidence refutes any association between epidural analgesia in labour and the later development of autism spectrum disorder. The clinical significance of epidural related maternal fever remains uncertain and is a research priority.

Summary: Women should continue to access the significant benefits of neuraxial analgesia in labour without undue concern about adverse sequelae for themselves or their offspring. Measures to prevent, appropriately manage and adequately follow-up women who have suffered complications of neuraxial analgesia, such as postdural puncture headache, are good practice and can mitigate the development of long-term sequelae.
