Combination vasoactive medication use in asphyxiated newborn piglets

Manouchehri, Namdar 11 1900 (has links)
With asphyxia, newborns may suffer cardiogenic shock with myocardial dysfunction and dysregulation of vasomotor tone resulting in multiorgan dysfunction. Vasoactive medications are often administered with limited evidence directing clinicians regarding the use of high-dose monotherapy with dopamine relative to combination treatment with dopamine and a second different agent. We hypothesized that the treatment of hypoxia-reoxygenated newborn piglets with combinations of vasoactive medications would improve systemic and regional hemodynamics. Instrumented newborn piglets were subjected to hypoxia-reoxygenation with subsequent infusion of high-dose dopamine or moderate-dose dopamine and one of epinephrine, milrinone or levosimendan. Treatment with high-dose dopamine improved systemic and mesenteric perfusion. The addition of low-dose epinephrine showed some benefits regarding pulmonary hypertension and should a non-catecholamine agent be added to dopamine, milrinone is preferred to levosimendan given benefits to mesenteric perfusion. We conclude that the selection of appropriate vasoactive medical therapy should be directed by the clinical effects desired. / Experimental Surgery
