STUDY OBJECTIVE: Our primary objective was to characterize the degree of dehydration in children with diabetic ketoacidosis (DKA) and identify physical examination and biochemical factors associated with dehydration severity. Secondary objectives included describing relationships between dehydration severity and other clinical outcomes.

METHODS: In this cohort study, we analyzed data from 753 children with 811 episodes of DKA in the Pediatric Emergency Care Applied Research Network Fluid Therapies Under Investigation Study, a randomized clinical trial of fluid resuscitation protocols for children with DKA. We used multivariable regression analyses to identify physical examination and biochemical factors associated with dehydration severity, and we described associations between dehydration severity and DKA outcomes.

RESULTS: Mean dehydration was 5.7% (SD 3.6%). Mild (0 to <5%), moderate (5 to <10%), and severe (≥10%) dehydration were observed in 47% (N=379), 42% (N=343), and 11% (N=89) of episodes, respectively. In multivariable analyses, more severe dehydration was associated with new onset of diabetes, higher blood urea nitrogen, lower pH, higher anion gap, and diastolic hypertension. However, there was substantial overlap in these variables between dehydration groups. The mean length of hospital stay was longer for patients with moderate and severe dehydration, both in new onset and established diabetes.

CONCLUSION: Most children with DKA have mild-to-moderate dehydration. Although biochemical measures were more closely associated with the severity of dehydration than clinical assessments, neither were sufficiently predictive to inform rehydration practice.

Acute kidney injury occurs frequently during pediatric diabetic ketoacidosis (DKA). We reviewed urinalyses from 561 children with DKA; pyuria was detected in 19% overall and in 40% of children with more comprehensive urine testing (≥3 urinalyses) during DKA.

<p><strong>OBJECTIVE: </strong>Fluid replacement to correct dehydration, acidosis, and electrolyte abnormalities is the cornerstone of treatment for diabetic ketoacidosis (DKA), but little is known about optimal fluid infusion rates and electrolyte content. The objective of this study was to evaluate whether different fluid protocols affect the rate of normalization of biochemical derangements during DKA treatment.</p>

<p><strong>RESEARCH DESIGN AND METHODS: </strong>The current analysis involved moderate or severe DKA episodes ( = 714) in children age &lt;18 years enrolled in the Fluid Therapies Under Investigation in DKA (FLUID) Trial. Children were assigned to one of four treatment groups using a 2 × 2 factorial design (0.90% or 0.45% saline and fast or slow rate of administration).</p>

<p><strong>RESULTS: </strong>The rate of change of pH did not differ by treatment arm, but Pco increased more rapidly in the fast versus slow fluid infusion arms during the initial 4 h of treatment. The anion gap also decreased more rapidly in the fast versus slow infusion arms during the initial 4 and 8 h. Glucose-corrected sodium levels remained stable in patients assigned to 0.90% saline but decreased in those assigned to 0.45% saline at 4 and 8 h. Potassium levels decreased, while chloride levels increased more rapidly with 0.90% versus 0.45% saline. Hyperchloremic acidosis occurred more frequently in patients in the fast arms (46.1%) versus the slow arms (35.2%).</p>

<p><strong>CONCLUSIONS: </strong>In children treated for DKA, faster fluid administration rates led to a more rapid normalization of anion gap and Pco than slower fluid infusion rates but were associated with an increased frequency of hyperchloremic acidosis.</p>
