©2013 UpToDate ® Print Email Protocol for the management of adult patients with DKA DKA diagnostic criteria: serum glucose >250 mg/dl, arterial pH <7.3, serum bicarbonate <18 mEq/l, and moderate ketonuria or ketonemia. Normal laboratory values vary; check local lab normal ranges for all electrolytes. IV: intravenous; SC: subcutaneous. * After history and physical exam, obtain capillary glucose and serum or urine ketones (nitroprusside method). Begin one liter of 0.9 percent NaCl over one hour and draw arterial blood gases, complete blood count with differential, urinalysis, serum glucose, BUN, electrolytes, chemistry profile, and creatinine levels STAT. Obtain electrocardiogram, chest X-ray, and specimens for bacterial cultures, as needed. • Serum Na + should be corrected for hyperglycemia (for each 100 mg/dl glucose >100 mg/dl, add 1.6 mEq to sodium value for corrected serum sodium value). Δ An alternative IV insulin regimen is to give a continuous intravenous infusion of regular insulin at 0.14 units/kg/hour; at this dose, an initial intravenous bolus is not necessary.
