Dehydration scores were classified according to the percentage of dehydration as score 1 in cases of less than 6%, score 2 in cases of less than 8%, score 3 in cases of less than 10%, and score 4 in cases of 10% or more. Blood parameters were compared among groups by using one-way analysis of variance followed by Tukey's post hoc multiple-comparison tests.
BE, base excess of the extracellular fluid; tCO2, total carbon dioxide; HCO3−, bicarbonate; Na+, sodium; Glu, glucose; pCO2, partial pressure of carbon dioxide; Cl−, chloride; K+, potassium; Hct, hematocrit; Hb, hemoglobin; AnGap, anion gap; BUN, blood urea nitrogen.
