Summary

Amnioinfusion for meconium-stained liquor in labour

Amnioinfusion is beneficial for babies releasing medium to heavy meconium during labour, although further research into the effects on women is needed.

A bowel movement (meconium) from the unborn baby during labour can enter the baby's lungs, causing breathing difficulties after birth. Extra liquid can be injected through the woman's vagina or abdomen into the womb (amnioinfusion) to provide more liquid to dilute the meconium and surround the baby. The review of trials found that amnioinfusion with a salt (saline) solution is beneficial for babies releasing medium to heavy meconium during their mother's labour. They are less likely to breathe in meconium or need breathing assistance after birth, and have better heart rates. Further research into the effects on women is needed.
