A 32-year-old primigravida was admitted at 40 weeks' gestation for induction of labor following amniorrhexis
. She had a history of an untreated herniated lumbar disk.
Preterm prelabor amniorrhexis
: outcome of live births.
[3,4,5,6] For these women, the prognosis for an uneventful peripartum course remains excellent, and the premature amniorrhexis
can be considered a physiologic, rather than a pathologic event.
(13) Polzin et al had concluded that amniorrhexis
occurs as a result of proteolytic enzyme-mediated weakening of the foetal membranes in the region of the cervix or the lower uterine segment.
Prelabour rupture of membranes (PROM) is amniorrhexis
in the absence of labour, irrespective of gestational age.
