Data are shown as mean ± SD or median [interquartile range]. RL: Ringer’s lactate; 20%ALB: 20% albumin; 5%ALB: 5% albumin. Comparisons were done using Mauchly’s test of sphericity with repeated-measures ANOVA (p < 0.05). If epsilon was > 0.75, the Huynh-Feldt p-value was shown (superscript a); otherwise, the Greenhouse-Geisser p-value was shown (superscript b). Additionally, to compare all parameters among groups at each time point, a mixed linear model based on a random intercept for each animal followed by Bonferroni’s test. For comparison of total volume infused, the Kruskal–Wallis test was used. MAP: mean arterial pressure; HR: heart rate: dIVC: distensibility index of the inferior vena cava; SV: stroke volume; LVIDD: left ventricular internal diastolic diameter. * vs RL (p < 0.05); # vs 5%ALB (p < 0.05); † vs Initial (p < 0.05)
