ABSTRACT
DEFINITION Premature rupture of membranes is rupture of fetal membranes prior to the onset of labor (1). Preterm premature rupture of membranes (PPROM) is premature rupture of fetal membranes 37 weeks (1). This chapter includes guidance for near-term (34-36 6/7 weeks) as well as term (37 weeks) PROM. For PPROM < 34 weeks, see chapter 18.
DIAGNOSIS The diagnosis of PROM and PPROM is based on history and physical examination findings (see also chap. 18). A maternal history suggestive of PROM includes a gush of fluid soaking clothes or a constant trickle of fluid that does not stop. Physical exam for PROM starts with a sterile speculum examination (1-3). Visualization of amniotic fluid passing from the cervical canal is diagnostic of this condition (1-3).
