UBS = Un-Balanced Solution group; BS = Balanced Solution group; HR = Heart rate; MAP = mean arterial pressure; CVP = central venous pressure; NGAL = neutrophil gelatinase-associated lipocalin.
Results are expressed as mean ± SD.
* P < 0.05 comparison made between the two groups.
§ P < 0.05 comparison made within each group having T0 as a control value.
