f^j umbiiicai blood flow in pregnant sheep

Bolus injections or continuous infusions with catecholamines either intravenously or directly intraarterially in the pelvic vessel cause vasoconstriction and a decrease in blood flow in various vessels of the maternal pelvic arterial bed as the common internal iliac artery, the internal iliac artery and the median uterine artery with a probably more marked effect on median uterine artery blood flow [1, 5, 6, 11].
