Discussion: Diabetic Ketoacidsosis
(DKA)
Kitabchi et al, 2001 Management of Hyperglycemic Crises in Patients With Diabetes. Diabetes care Journal, Vol 24, No.1, January 2001.
Mechanisms behind DKA
Lack of insulin
Decreased uptake of glucose
Hyperglyceamia
Osmotic diuresis
Dehydration
Elevated counterregulatory
hormones
Increased hepatic glucose
production
Increased lipolysis, fatty
acid oxidation
Ketosis
Metabolic acidosis
Management
1. Fluid balance
2. Replace Insulin
3. Treat and monitor the potassium level
4. Treat the underlying cause
Conclusion
Patient education and concordance
Insulin pump
Prevention is better than cure!
