Umbilical cord prolapse during delivery – risk factors and pregnancy outcome: a single center experience

AbstractObjective: To determine the incidence and risk factors for umbilical cord prolapse and to evaluate whether obstetrical interventions increase this risk.Methods: A retrospective, cohort study of all intended vaginal deliveries in a single tertiary university affiliated medical center (33 519 deliveries). Obstetrical and labor characteristics, including labor interventions [as artificial rupture of membranes (ARM) and intrauterine catheter insertion] and short-term pregnancy outcome were obtained. Primary outcome measure was defined as abnormal umbilical cord pH <7.2 and/or 5-min Apgar score <7.Results: The rate of umbilical cord prolapse was 37/33 519 (0.11%); of them, 23 (62%) were diagnosed after ARM, three cases (8%) were related to external cephalic version and three cases (8%) were related to intrauterine catheter insertion. The rate of umbilical cord pH <7.2 and 5-min Apgar score <7 was higher in the ARM group in comparison to women with spontaneous rupture of membranes (30% versus 21%, p = 0...
