ABSTRACT
OBJECTIVE: Cerebral edema is a severe and potentially fatal complication of diabetic ketoacidosis (DKA), particularly in pediatric patients. Despite its clinical significance, limited data exist on its incidence and associated risk factors in resource-limited settings. This study aimed to determine the incidence of cerebral edema in pediatric patients with DKA and investigate potential contributing factors. This retrospective study analyzed data from 270 pediatric DKA patients admitted to the Children’s Medical Center Hospital, Tehran, between March 2018 and March 2020. Patients aged 1 day to 18 years were included based on standard DKA diagnostic criteria (blood glucose > 250 mg/dL, pH < 7.3, bicarbonate < 18 mEq/L, and ketonemia/ketonuria). Patients with incomplete records or pre-existing neurological conditions were excluded. The statistical analyses included independent t-tests and Fisher’s exact tests.
RESULTS: The incidence of cerebral edema was 6.67%. Elevated blood glucose levels at admission were significantly associated with cerebral edema (P = 0.01), suggesting a potential role in its pathophysiology. Additionally, a strong correlation was observed between cerebral edema and ICU admission (P < 0.001), indicating a more severe disease course. The results suggest that early glucose control and neurological monitoring are critical for preventing adverse outcomes such as cerebral edema in pediatric DKA patients.
