Premature rupture of membranes

Radswiki et al.

A premature rupture of membranes (PROM) refers to a rupture of the amniotic sac + chorion (membranes) occurring prior to the onset of uterine contractions. When this occurs prior to 37 weeks it is then termed a pre term premature rupture of membranes (PPROM). By this definition the PROM is classified as a rupture of membranes between 37 weeks and term.

Epidemiology

The estimated incidence is at ~ 10% of pregnancies at term and ~ 0.7 - 2.0% of pregnancies before 37 weeks (for PPROM).

Complications

increased risk of chorioamnionitis
