Fluid treatment for children with diabetic ketoacidosis: How do the results of the pediatric emergency care applied research network Fluid Therapies Under Investigation in Diabetic Ketoacidosis (FLUID) Trial change our perspective?

The optimal fluid treatment protocol for children with diabetic ketoacidosis (DKA) has long been a subject of controversy. Until recently, there was no high-quality evidence from randomized clinical trials to support an optimal guideline, and recommendations were mainly based on theoretical considerations. As a consequence, fluid treatment protocols for children with DKA vary between institutions (and countries). In June 2018, the results from the Fluid Therapies Under Investigation in DKA Trial conducted in the Pediatric Emergency Care Applied Research Network were published. This large, factorial-designed randomized controlled trial assessed neurological outcomes of 1387 children with DKA who were treated with one of four fluid protocols that varied in infusion rate and sodium content. In this commentary, we review and discuss the results of this new study and the implications for clinical care of DKA in children.
