In medicine, diabetic ketoacidosis (DKA) is a type of metabolic acidosis that is a "life-threatening complication of diabetes mellitus, primarily of Type 1 Diabetes Mellitus with severe insulin deficiency and hyperglycemia. It is characterized by excessive lipolysis, oxidation of fatty acids, production of ketone bodies, a sweet smell to the breath (ketosis;) dehydration; and depressed consciousness leading to coma.[1] can also occur with Diabetes mellitus type 2[2]
DKA is often secondary to infection or other comorbidity, which must be diagnosed and treated.[3][4]
Diagnosis
The blood glucose is above 250 mg/dl in over 90% of patients.[5][6]
Urine test sticks measure acetoacetate and not 3-hydroxybutyrate (β-hydroxybutyrate) although 3-hydroxybutyrate is the predominant ketone. Acetoacetate may not be elevated until later.
The anion gap and serum osmolality must be measured.
Treatment
Treatment begins with fluid replacement; insulin is not started immediately. As DKA is treated, DKA converts from a high anion gap metabolic acidosis to a normal anion gap metabolic acidosis due to "excretion of ketone anions in the urine"[7], especially if excreted with sodium or potassium cations.
DKA is resolved when:[3]
- glucose level less than 11.1 mmol/L (200 mg/dL)
- two of
- serum bicarbonate level ≥ 15 mmol/L
- venous pH greater than 7.3
- anion gap < 12
When resolved and the patient is adequately eating, the patient should resume their usual insulin, or if the patient is a new diabetic, they should take a total of 0.5 to 0.8 U/kg per day.[3]
