β-Adrenoceptor Antagonist SR59230A Attenuates the Imbalance of Systemic and Myocardial Oxygen Transport Induced by Dopamine in Newborn Lambs
Background In neonates, the increase in O 2 -delivery (DO 2 ) by dopamine is offset by a greater increase in O 2 -consumption (VO 2 ). This has been attributed to β 3 -adrenergic receptors in neonatal brown fat tissue. β 3 receptors in the heart have negative inotropic properties. We evaluated the e...
