It has been proposed that vasodilatory therapy may increase microcirculatory blood flow and improve tissue oxygenation in septic shock. The authors aimed to evaluate the effects of levosimendan in systemic and splanchnic hemodynamics in a porcine model of septic shock in a randomized animal controlled study. This study was performed in an animal research facility in a university hospital. ⋯ Systemic blood pressure and vascular resistance did not differ as compared with the septic untreated group. Responses to noradrenaline significantly improved in animals treated with levosimendan. Treatment with levosimendan in this animal model of sepsis attenuated pulmonary vasoconstriction and improved portal blood flow, intestinal mucosal oxygenation, pulmonary function, and vascular reactivity.
