title: [Contribution to acid-base metabolism in hypertonic dehydration by the study of "fraction R" (underterminate anions) (author's transl)].
abstract: A study on the value of "R fraction" of plasma electrolites (undetermined anions), in order to know better the metabolic acidosis of the hypertonic dehydration is achieved. "R fraction" value was obtained by the formulae: R fraction = plasma N+ --(plasma Cl- + plasma HCO3-). The mean values in patients with hypertonic dehydration was: 12.4 +/- 8.3 mEq./l., more than the normal standard data of our laboratory: 8.55 +/- 3.4 mEq./l. Authors make two groups in accordance with the "R" value: one with low "R fraction" (25 cases): 4.79 +/- 4.70 mEq./l.; and another with high "R fraction" (32 cases): 20.04 +/- 6.6 mEq./l., and compare the differences (ethiologic, clinic, shock and metabolic) between the two groups. It is confirmed that acidosis in hypertonic dehydration is essentially hyperchloremic. It was speculated on the "anion gap" and the total value of chloride in this dehydration.
