Importance Diabetic ketoacidosis (DKA) is a serious complication of type 1 diabetes mellitus, which may lead to significant morbidity and mortality.
Objectives To compare the safety and efficacy of liberalised versus conservative intravenous fluid regimens in the management of DKA in children.
Data source and study selection Databases from inception to January 2022: MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials were included. Only randomised controlled trials (RCTs) that included children aged under 18 years were assessed. Two reviewers performed data assessment and extraction.
Data extraction and synthesis Three studies out of 1536 citations were included.
Main outcomes The time to the recovery from the DKA; the frequency of paeditric intensive care unit (PICU) admissions; development of brain oedema; reduction in Glasgow Coma Scale (GCS); development of acute kidney injury and all-cause mortality.
Results We included three RCTs (n=1457). No evidence of difference was noted in the GCS reduction (risk ratio (RR)=0.77, 95% CI 0.44 to 1.36) or development of brain oedema (RR=0.50, 95% CI 0.15 to 1.68). The time to recovery from DKA was longer in the conservative group (mean difference=1.42, 95% CI 0.28 to 2.56). Time to hospital discharge, adverse or serious adverse events were comparable in the two studied groups.
Conclusion There is no evidence from this meta-analysis that rate of fluid administration has any effect on adverse neurological and other outcomes or length of hospital stay.
