Abstract
This study aims to determine whether levosimendan combined with arginine vasopressin infusion supplemented with norepinephrine can improve hemodynamics and pulmonary dysfunction. The study was tested in a fecal peritonitis-induced septic shock model, we observed that levosimendan combined with arginine vasopressin supplemented with norepinephrine therapy resulted in lower mean pulmonary artery pressure, lactate concentrations, arterial total nitrate/nitrite, and high-mobility group box 1 levels; decreased lung wet/dry ratio, and pulmonary levels of interleukin-6, total histological scores, and improved pulmonary gas exchange when compared with norepinephrine group. Levosimendan combined with arginine vasopressin supplemented with norepinephrine infusion shows potential benefit in sepsis-induced acute lung injury by decreasing mean pulmonary artery pressure and attenuating inflammatory responses in the lung compared to norepinephrine infusion alone.
