Objectives: The objective of this study was to investigate the significance and prevalence of lactic acidosis in pediatric diabetic ketoacidosis (DKA) presenting to the emergency department.
Methods: A retrospective cohort study of children (age ≤ 21 years) presenting to a tertiary care emergency department in DKA from December 1, 2015 to December 1, 2018. Patients needed to have DKA requiring admission to the pediatric intensive care unit and have had a lactate level collected while in the emergency department to be included.
Results: 92 patients resulting in 113 encounters had DKA and a lactate level collected in the emergency department. The mean lactate level was 3.5 mmol/L (±SD 2.1). 72 (63.7%) encounters had lactic acidosis (p < 0.001). There was no significant association between the presence of lactic acidosis and pediatric intensive care unit length of stay (p = 0.321), hospital length of stay (p = 0.426), morbidity (p = 0.552) and mortality (p = 1.000). Initial glucose levels were significantly higher in the patients presenting with lactic acidosis (p = 0.001).
Conclusions: Lactic acidosis is a common finding in pediatric DKA patients presenting to the emergency department. Serum lactate alone should not be used as an outcome predictor in pediatric DKA.
