Dynamics of cardiovascular responses to repeated partial umbilical cord compression in late-gestation sheep fetus.
We characterized the detailed hemodynamics of fetal blood pressure, heart rate, common umbilical blood flow, and femoral blood flow responses to partial compression of the umbilical cord and testedExpand

Changes in adrenocorticotropin and cortisol responsiveness after repeated partial umbilical cord occlusions in the late gestation ovine fetus.
Despite many studies reporting fetal ACTH and cortisol (F) responses to acute fetal hypoxemia induced by several methods, effects of repeated short-term fetal hypoxia produced by umbilical cordExpand
