*SROM: spontaneous<unk> . This term describes the normal, spontaneous rupture of the<unk>  at full term. The rupture is usually at the bottom of the uterus, over the cervix, causing a gush of fluid. This gush may be quite small (such as 50ml), or it can be significantly large (200-300ml) depending upon amount of fluid in the amniotic sac, and to what extent the fetal head is plugging the hole and retaining fluid in the sac. A spontaneous rupture that occurs early in labor may actually be related to other complications resulting in delayed labor. These complications may include a contracted pelvis, breech presentation, or occipito-posterior position. *PROM: premature<unk> . This term describes a rupture of the<unk>  that occurs before the onset of labor. *PPROM: preterm, premature<unk> . This term describes a rupture of the<unk>  that occurs before 37 weeks gestation, and it can have multiple effects on the fetus such as increasing his/her risk of prematurity and facing neonatal or perinatal complications. Risk factors of pregnancies suffering from PPROM include race - with black patients at increased risk - socioeconomic status, history of sexually transmitted disease, and smoking. *AROM: artificial<unk> . This term describes a rupture of the<unk>  by a third party, usually a midwife or obstetrician, in order to induce or accelerate labor.
