Perineal Trauma
Perineal trauma occurs in up to 85% of vaginal deliveries. Classification: 1st degree (skin only), 2nd degree (skin + perineal muscle), 3rd degree (partial/complete external anal sphincter), 4th degree (through to anorectal mucosa). 3rd/4th degree = OASI (obstetric anal sphincter injury).
