Abstract
Purpose and methods: Recommendations of fluid requirements of healthy children given by pediatric textbooks have been theoretically derived, but not experimentally confirmed by direct measurements. In this study, waler turnover was measured in 171 healthy children (88 f, 83 m, 1.5 mths-15 yrs) living in their normal milieu using the established technique of dcutcriumoxide dilution: oral application 2ml D2O/kg body weight, analysis of urine content by IR-spectroscopy1). Results: Measured and Recommended2) values per body weight and day [ml H2O/kg/d] are shown in the following table:
Discussion: These are the first measured data of water turnover during childhood. After correcting the influence of oxidation water, we conclude that spontaneous daily fluid intake during the first year of life is in the lower range of the recommendations. For older children, however, the recommendations exceed the measured values by the factor 1.2 to 2.
