Uterine rupture during induced or augmented labor in gravid women with one prior cesarean delivery.
Our purpose was to examine the risk of uterine rupture during induction or augmentation of labor in gravid women with 1 prior cesarean delivery. ⋯ Induction of labor with oxytocin is associated with an increased rate of uterine rupture in gravid women with 1 prior uterine scar in comparison with the rate in spontaneously laboring women. Although the rate of uterine rupture was not statistically increased during oxytocin augmentation, use of oxytocin in such cases should proceed with caution.

Association between umbilical blood gas parameters and neonatal morbidity and death in neonates with pathologic fetal acidemia.
Our purpose was to correlate umbilical artery blood gas parameters with neonatal death and indicators of morbidity in neonates with pathologic fetal acidemia (pH <7.0). ⋯ Our data suggest that "pathologic" fetal acidemia is indicated by an umbilical artery pH <7.00 with a metabolic component. The metabolic component of fetal acidemia (ie, base deficit and bicarbonate) is the most important variable in subsequent neonatal morbidity. As expected, the umbilical artery PO (2) has no apparent clinical utility. The ability to predict more accurately which newborn infants with fetal acidemia are at risk of having complications may lead to a more efficient implementation of preventive measures.
