Premature rupture of the membranes

Since 1970 there have been many changes in our knowledge of premature rupture of the membranes (PROM). Studies of its causes have focused on clinical variables, physical properties of the membranes, and subclinical infection, while new diagnostic techniques have included biochemical and histochemical tests, as well as intrauterine dye injection. Within the last decade, new approaches in management have employed corticosteroids, tocolytics, and amniocentesis. Because of limitations of current studies, however, it is difficult to compare one study to another. Consequently, management of PROM remains a major dilemma. This review provides a summary and commentary on recent works.
