Expectant Management of Placental Abruption: Risk Factors for Progression and Morbidity

Clinical outcomes in expectantly managed placental abruption are poorly described with few published data to guide management in cases that do not warrant immediate delivery. Our primary objective was to describe the incidence of severe abruption, defined as maternal or fetal instability requiring immediate delivery, in patients with placental abruption who were stable at admission (mild abruption). We also sought to determine factors associated with progression to severe abruption.
