Investigating the Risk Factors Associated With Acute Neurologic Dysfunction in Pediatric Hyperglycemic Emergencies on Transport.

Objective: This study aims to identify key characteristics of hyperglycemic emergencies in pediatric patients and those at risk for acute neurologic dysfunction during transport.

Methods: We conducted a retrospective chart review of pediatric patients during interfacility transport by Ornge, Ontario's critical care transport service, from January 1, 2009, to December 31, 2019. Data were extracted from electronic patient care records and included demographic, clinical, and transport-specific variables. Two multiple logistic regression models were utilized to analyze associations between predictor variables and neurologic dysfunction (GCS, <14).

Results: Of the 399 patients included, 24% (n = 95) had a GCS score of <14. Patients with a GCS score of <14 were more acidotic compared with those with a GCS score of ≥14 (median pH, 6.9 [IQR, 6.8-7.1] vs median, pH 7.0 [IQR, 1.0-7.2]; P < 0.001). Higher median corrected sodium for glucose values were observed in patients with a GCS score of <14 compared to those with a GCS score of ≥14 (145.7 mmol/L [IQR, 140.6-149.9 mmol/L] vs 141.7 mmol/L [IQR, 138.3-146.4 mmol/L]; P < 0.001). Multiple logistic regression identified younger age (aOR, 0.91; 95% CI, 0.84-0.98; P = 0.01), severe acidosis (pH <7.10; aOR, 3.56; 95% CI, 1.33-11.62; P = 0.02), and higher creatinine (aOR, 1.01; 95% CI, 1.01-1.02; P < 0.001) as risk factors for acute neurologic dysfunction.

Conclusions: Our findings reveal associations between acute neurologic dysfunction, younger age, severe acidosis, and elevated corrected sodium for glucose values in pediatric hyperglycemic emergencies during transport. Education and adherence to guidelines are recommended to improve outcomes in this population.
