Venous-arterial pCO₂ gradient (D(v-a)pCO₂; mmHg, mean ± standard error of the mean (SEM)), portal-arterial pCO₂ gradient (D(p-a)pCO₂; mmHg, mean ± SEM) and gastric mucosal-arterial pCO₂ gradient (D(g-a)pCO₂; mmHg, mean ± SEM) during the experimental protocol. LR group received lactated Ringer's solution 32 ml/kg over 30 minutes, n = 7; HS group received 7.5% hypertonic saline solution 4 ml/kg over 5 minutes, n = 8. *p < 0.05 versus T0, both groups; ^# HS, p < 0.05 versus T0.
