Abstract
The urinary excretion of the quantitatively prevalent ions and nonionic solutes and of aldosterone-18-glucuronide was investigated in 49 healthy children and 22 healthy adults living at home. The median of renal net-acid-excretion was 0.99 meq/kg/day or 48 meq/day/1.73 m2 in children, and 0.75 meq/kg/day or 50 meq/day/1.73 m2 in adults. The median of osmolar load was 12.8 mosmol/kg/day or 643 mosmol/day/1.73 m2 in children, and 10.6 mosmol/kg/day or 661 mosmol/day/1.73 m2 in adults. High urinary osmolality was more frequently observed in children than in adults. The data may define a desirable range of renal net-acid-excretion (0.5-1.5 meq/kg/day) in children receiving synthetic diets.
