Postpartum Perineal Pain After Obstetric Anal Sphincter Injuries: A Randomized Clinical Trial

Obstetric anal sphincter injuries (OASIS) encompass both third and fourth degree perineal
tears. These tears can have a significant impact on women's quality of life in the short and
long term. One of the most distressing immediate complications of this severe perineal injury
is perineal pain. Women can also experience postpartum depression, dyspareunia, and altered
sexual function after OASIS.

This is a randomized controlled trial to study the effects of three interventions (placebo,
low dose intravenous ketamine plus epidural morphine, or epidural morphine alone) on acute
pain after OASIS.

The objective of this study is to assess the incidence of perineal pain in postpartum
patients 1 week after obstetric anal sphincter injuries.
