DKA/HHS Flashcards
Which has more severe hyperglycemia? DKA or HHS
HHS
DKA or HHS?
More common under 65, associated with type one diabetes, rare with type two
DKA
DKA or HHS?
Common with type two diabetes, more common with people over 65 years old
HHS
DKA often present earlier with symptoms of Keto acidosis, such as
Shortness of breath, abdominal pain, nausea, vomiting
Ketone production
Insulin deficiency in resistance
Can not get glucose in the cells, So body uses fat for energy (lipolysis)
Release of fatty acids and glycerol
Fatty acids transported to liver and become activated
Fatty acids been converted to acetyl-CoA, forming ketone bodies
Accumulation of ketone bodies causes a drop in pH (metabolic acidosis)
Does DKA or HHS typically present with an elevated anion gap
DKA
Severity of acidosis and increase of anion gap depends on
Read induration of keto acid production, rate of metabolism of keto acids, rate of loss of ketoacid anion in urine
Glucosuria Causes automatic diuresis leading to
Excretion of sodium, potassium, and water
Do DKA and HHS have hyper or hypo kalemia?
Hypokalemia
This is due to increased urinary loss, or G.I. losses
What are some precipitating factors for DKA or HHS
In section without insulin adjustment, acute major illness or inflammatory process, new onset of type one diabetes, drugs that affect carbohydrate metabolism, use of SGL T2 inhibitors, substance abuse, poor compliance with insulin regimen for faulty SQ insulin infusion devices
How does a patient with DKA present
There’s a rapid onset
polyuria, polydipsia, GI Effects like nausea, vomiting, abdominal pain,
may have neurological effects (Combative, drunk like, coma)
volume depletion (And decreased skin turgor, dry oral mucosa, tachycardia, hypotension),
Fruity odor of breath, Kussmaul respirations
HHS clinical presentation
Insidious onset of polyuria, polydipsia, and weight loss over several days
As glucose continues to increase patient becomes lethargic, obtunded, or comatose
Signs of volume depletion occur, similar to DKA
Treatment of decay and HHS
Fluid replacement, correction of electrolytes, insulin infusion, sodium by carbonate (DKA), And dextrose may be added to saline solution if patient still has an anion gap
What does it look like when DKA is resolved?
Keto acidosis has resolved in the anion gap has closed. Patient is able to eat and can transition back to subcutaneous insulin
What does it look like when HHS has resolved?
Patient is mentally alert and plasma osmolality has dropped to 315. Patient is able to eat and can transition back to subcutaneous insulin
