Summary
Brief summary (as posted)
It is unknown if primary delivery of the anterior or the posterior shoulder causes less perineal tear. The objective of this trial is to evaluate the incidence and degree of perineal trauma after primary delivery of the anterior shoulder compared to primary delivery of the posterior shoulder during vaginal birth in primiparous women in a randomized controlled trial. The hypothesis is that primary delivery of the posterior shoulder reduces the rate and degree of perineal trauma.
