"Pharmacology CC: DKA & HHS Marisa E. Desimon" Flashcards
Name the counterregulatory hormones.
Glucagon
Cortisol
Growth hormone
Epinephrine
**Increased glycogenolysis in DKA/HHS
What are the 3 I’s w/r/t DKA and HHS?
Infection
Insulin
Infarct
Infection->counter-reg hormone increase-> insulin resistance -> hyperglycemia->dehydration
These symptoms describe what disorder?
• Absolute or relative insulin deficiency
• Increase in counter-regulatory hormones – Stress, infection, medications
• Volume depletion (5-12L)
DKA and HHS
Name the dx:
- Type 1 DM
- Generally Young
- Abdominal discomfort
- Vomiting
- Kussmaul Respirations • Vascular Shock
- Mental Status Changes
DKA
Name the dx:
• Type 2 DM • Generally Elderly • Debilitating disease • Volume contraction • Generally without ketoacidosis • Mental Status Changes
HHS
What is the triad of DKA?
Triad
- Hyperglycemia
- Metabolic acidosis
- Ketone production
What is the triad of HHS?
- Hyperglycemia
- Hyperosmolality
- Dehydration
absence of ketoacidosis
How is insulin administration transitioned after DKA?
MUST overlap insulin infusion with subcutaneous insulin by 1-2 hours to prevent recurrence of hyperglycemia/ketoacidosis
What is the major complication to hypokalemia?
Ventricular arrhythmia
When should bicarbonate be given as part of a tx for DKA?
Give in severe acidosis (pH 6.5 or EKG changes), but need to individualize
How do you track the resolution of DKA?
Follow anion gap (less than 12), and glucose
– Can follow β-hydroxybutyrate if you choose
What are poor prognostic factors in DKA an HHS?
Hypotension, azotemia, deep coma, associated illness are poor prognostic factors
How is DKA treated?
- fluids
- insulin
- potassium if needed
- monitor electrolytes and anion gap closely (every 2-4 hours)
When treating DKA, the glucose should drop how much?
When treating DKA, the glucose should drop about 50-75mg/dL/hr.
Why is the anion gap important in monitoring the resolution of DKA?
Follow anion gap
• Don’t follow glucose as this will resolve prior to resolution of ketones
• Don’t follow ketones unless measuring β-hydroxybutyrate directly.
