ABSTRACTPremature rupture of membranes (PROM) is a common obstetric occurrence; yet, the management of a patient who presents with PROM is controversial. This article reviews the etiology of PROM, describes the evaluation of a patient who presents with PROM, and enumerates the pitfalls inherent in making the diagnosis. Research suggests that an expectant approach to PROM at term is preferable to immediate induction. The use of PGE2gel is an option for women who have unfavorable cervices. Clinical management of preterm premature rupture of membranes (PPROM) is generally expectant, with controversies surrounding the use of amniocentesis, corticosteroids, and tocolytics. Each of these topes is reviewed and current research summarized.
