Effect of continuous Infusion of fenoterol on maternal pelvic and fetal umbilical blood flow in pregnant sheep

Fenoterol: Pharmacology and Clinical Use

“…In other animal experiments, the effects of fenoterol on umbilical blood flow were studied (55). These experiments were carried out in pregnant sheep and demonstrated that continuous infusion of fenoterol to the mother at therapeutically used doses has no effect on the fetal umbilical circulation.…”

Pharmacology of the ovine uterine artery and umbilical blood vessels: Serotonergic and α-adrenergic mechanisms

“…j8-Adrenergic agonists are weak vasodilators in the uterine vascular bed of nonpregnant (Barton et al, 1974;Greiss and Gobble, 1967;Resnik et al, 1976) and pregnant ewes (Erkkola et al, 1981;Hasaart and de Haan, 1987). The vascular response to j8-adrenergic agonists is reduced in pregnant animals (Erkkola et al, 1981).…”
