What defines preterm premature rupture of membranes (PPROM)?

Preterm premature rupture of membranes (PPROM) is specifically defined as the rupture of the amniotic sac before 37 weeks of gestation and before the onset of labor. This condition is significant because it raises the risk for complications for both the mother and the baby, such as infections, preterm birth, and other obstetric issues.

The defining characteristic of PPROM is the absence of contractions at the time of rupture; hence, when membranes rupture before 37 weeks without any contractions, this is the clear indication of PPROM. The focus is on the timing of the rupture occurring before the onset of labor, which differentiates it from other forms of ruptured membranes that may happen later in gestation or during established labor.

Other options describe situations that are outside the specific definition of PPROM, such as premature rupture with contractions or rupture occurring after the gestational age of 37 weeks, which is classified as term premature rupture of membranes and not considered preterm. Thus, the correct understanding lies in recognizing that PPROM pertains strictly to rupture before 37 weeks gestation without the presence of labor contractions.
