The dynamic equilibrium of fluid, electrolyte, acid- base, osmotic pressure depends on normal regulating function of nerve, incretion, lung and kidney. Because of the infantile physiologic peculiarity, These systematic functions are easily affected by diseases and/or environment and are maladjusted. Therefore, the disorder of water, electrolyte and acid-base is common in pediatric clinic. Characteristic of Infantile Body Fluid Balance A. Total body water & its distribution Body water compartments related to age (total body mass%)   40 ～ 4510 ～ 15555 ～ 66Adult 40205662 ～ 14 years 40255701 year 3537678 Newborn infant ISFPlasma ICF ECF TBWAge TBW: total body water ECF: extracellular fluid ICF: intracellular fluid ISF: interestitial fluid Characteristic of Infantile Body Fluid Balance B. Electrolyte composition of body fluid ECF: Na+ 、 Cl- ， HCO3 - ICF: K + 、 Mg 2+ 、 HPO4 2- 、 Protein C. Water metabolism a. Large water requirements, swift water exchange, unobvious water loss (double adult’s amount ). Infant’s water exchange amount is 1 / 2 of ECF , the adult’s is just 1 / 7. b. Immature body liquid regulating function , immature concentration and dilution function of infantile. ...
