"Pitfalls in DKA"Dr. Jeannette Goguen (biography)
English - 2005-01-21 - 31 minutes
|
 | (35 slides) |
Summary :
In this presentation Dr. Goguen uses case studies to illustrate some potential pitfalls in diagnosing or managing diabetic ketoacidosis (DKA).
Important considerations in DKA management are ECF volume contraction/ water balance, acidosis, K+ depletion, hyperglycaemia and the precipitating cause.
A diagnosis of DKA can be missed if the pH is normal due to a compensatory respiratory or metabolic alkalosis, or if the ketone assay measuring only acetoacetic acid and acetone fails to detect the patient with elevated beta-hydroxybutyrate.
In the treatment of DKA, an increased positive ketone assay and failure of bicarbonate to normalize do not necessarily mean the ketoacidosis is getting worse.
Dr. Goguen reviews these different scenarios and two potential causes of death in DKA: hypokalemia and cerebral edema, in terms of the underlying causes and clinical implications.
