Don’t gloss over perineal trauma risk: obstetricians

Women planning vaginal birth after a previous caesarean delivery should be warned about their higher risk of obstetric anal sphincter injury, researchers say

Women birthing vaginally after a prior C-section are 21% more likely to sustain a severe perineal tear than primiparous women having vaginal births, Australian clinicians warn.

Their findings, based on data from 130,000 parous women, suggest the need to update antenatal counselling to better reflect the risk of obstetric anal sphincter injury (OASI), they say.
