And how to treat it? 4-Should the patient be admitted and where ?

350 0.9 139 3.5

1-Younger age < 5 years 2- New onset diabetes 3- Severe DKA.
Factors that increases risk of cerebral edema 1-Younger age < 5 years 2- New onset diabetes 3- Severe DKA. 4- Hypocapnia at presentation after adjusting of acidosis 5- Impaired renal function. 6- Bicarbonate treatment for correction of acidosis . 7- Greater volumes of fluid given in the first 4 h . 8- Administration of insulin in the first hour of fluid treatment
