Expectant management of preterm premature rupture of membranes and nonvertex presentation: what are the risks?

After transfer to an antenatal ward, patients with PPROM with nonvertex presentations appear to have a significantly higher risk for prolapsed umbilical cords, lower Apgar scores, and/or lower umbilical cord blood pH values, when compared with their vertex counterparts. Additionally, there appears to be substantial risk of an unintended, vaginal breech delivery.
