Time delivery
For mild to moderate polyhydramnios with reassuring fetal testing, there is no need to change standard obstetric management.
For severe polyhydramnios, care should be taken at the time of membrane rupture to avoid umbilical cord prolapse or abruption. One solution is to perform an amnioreduction in early labor; alternatively the membranes can be needled to allow gradual spillage of fluid, or can be ruptured at early cervical dilation, because prolapse of a loop of cord is more common as cervical dilation increases.
