214-OR: Effects of Fluid Rehydration Strategy on Correction of Acidosis and Electrolyte Abnormalities in Children with Diabetic Ketoacidosis

Background: Fluid replacement to correct acidosis and electrolyte abnormalities is the cornerstone of treatment of diabetic ketoacidosis (DKA). We evaluated the rates of change in pH, pCO2, anion gap, Na, K, and Cl in children randomized to four DKA fluid treatment protocols. Methods: From a large study conducted by The Pediatric Emergency Care Applied Research Network we used data from 714 children Results: The median age, sex, and baseline laboratory characteristic of the patients did not differ by treatment arm. The rate of change of pH did not differ by the arm, however the rate of rise of pCO2 was more rapid in the fast vs. slow fluid arms during the initial 4 h. The rate of decrease in anion gap was more rapid in the fast vs. slow arms during the initial 4 h and 8 h (p Conclusions: In children treated for DKA, faster fluid administration led to more rapid normalization of anion gap and pCO2 than slower fluid rates. However, more rapid fluid rates were associated with increased frequency of hyperchloremic acidosis. Disclosure A. Rewers: None. N.D. Kuppermann: Other Relationship; Self; InsuCalc. M.J.
