Prelabor rupture of membranesPrelabor rupture of membranes (PROM), previously known as premature rupture of membranes, is breakage of the amniotic sac before the onset of labor. Women usually experience a painless gush or a steady leakage of fluid from the vagina. Complications in the baby may include premature birth, cord compression, and infection. Complications in the mother may include placental abruption and postpartum endometritis. Risk factors include infection of the amniotic fluid, prior PROM, bleeding in the later parts of pregnancy, smoking, and a mother who is underweight.
