Background and Objectives Cerebral edema (CE) remains one of the most feared complications of diabetic ketoacidosis (DKA) with severe morbidity and mortality. The use of computerized tomography (CT) scan in the setting of suspected cerebral edema in DKA has been minimally studied. The objective of our study was to evaluate the utility of CT scans in children with suspected cerebral edema, and secondarily to analyze the various patient characteristics of those with and without cerebral edema. Methods We performed a retrospective chart review of all the children with DKA secondary to T1DM admitted to our tertiary PICU in order to obtain demographic data, laboratory results, and their treatment course. Differences between the groups of suspected CE and no suspected CE were compared using linear and logistic regression for continuous and binary variables respectively. Results We identified 251 patients with DKA, 12 of which had suspected CE; 67% (8/12) of those patients received head CT and 87.5% (7/8) of them were read as normal. On the other hand, 33% (4/12) did not receive CT scan of head, and yet three of the four patients were treated for CE. Conclusions In our cohort of patients, CT results did not influence CE treatment or lack thereof; most patients with suspected CE were treated with or without head CT findings of CE, indicating that imaging has very little utility in our cohort of patients. In some cases, the use of head CT delayed the onset of treatment for CE.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
