To investigate the protective effects of a newly invented device for reducing tears in the perineum during vaginal childbirth.


A multicenter randomized control trial performed at three hospitals in Sweden, in Helsingborg, Lund and Malmö. Participants recruited are women with vaginal delivery (N=1200), cephalic presentation. They will be randomized to an intervention group, with a perineal protection device, and a control group deliver as normal.

Main outcome measures:

The effect on the frequency and extension of perineal ruptures grade I, II and anal sphincter rupture are measured.

Condition or disease Intervention/treatment Phase
