Mentions: Urine sodium excretion in starved, ill children was lower than normal healthy nonstarved group (73 ± 43 vs 164 ± 68 mEq/L). Ill children hadnormal renal function, in isonatremic condition their urine sodium was significantly lower (83 ± 46 mEq/L) than normal group; while their urine UNa/Cr was higher than normal group (3.8 ± 5.5 vs 1.9 ± 1.5, P = 0.00), partly due to their lower creatinine excretion (38 ± 30 vs 128 ± 100 mg/dl). Changes of UNa/Cr in ill children is so wide, overlapped to what seen in healthy nonstarved children and opposite to what observed in spot urine sodium [Figure 1].
