Hypertonic sodium lactate improves microcirculation, cardiac function, and inflammation in a rat model of sepsis.


ABSTRACT: BACKGROUND:Hypertonic sodium lactate (HSL) may be of interest during inflammation. We aimed to evaluate its effects during experimental sepsis in rats (cecal ligation and puncture (CLP)). METHODS:Three groups were analyzed (n?=?10/group): sham, CLP-NaCl 0.9%, and CLP-HSL (2.5?mL/kg/h of fluids for 18?h after CLP). Mesenteric microcirculation, echocardiography, cytokines, and biochemical parameters were evaluated. Two additional experiments were performed for capillary leakage (Evans blue, n?=?5/group) and cardiac hemodynamics (n?=?7/group). RESULTS:HSL improved mesenteric microcirculation (CLP-HSL 736 [407-879] vs. CLP-NaCl 241 [209-391] UI/pixel, p?=?0.0006), cardiac output (0.34 [0.28-0.43] vs. 0.14 [0.10-0.18] mL/min/g, p?
