What Are The Causes Of High Potassium In Dogs?

Potassium is an electrolyte that is found in the cells and in the blood of your dog's body. An ideal potassium level is essential for controlling your dog's nerve impulses, brain function and muscle activity. It also plays a vital role in regulating your dog's heart function. The normal reference range for a dog's blood potassium level falls between 3.6 and 5.5 mEq/L. When your dog's potassium level dips too low, the condition is referred to as hypokalemia. Conversely, if his potassium level climbs too high, your dog is suffering from hyperkalemia. Your dog's potassium level is determined by performing a blood chemistry profile. Your dog's kidneys are responsible for filtering wastes from your dog's blood so that they may be expelled from your dog's body when he urinates. Optimal kidney function is vital to maintaining healthy levels of enzymes, minerals and other important substances, including potassium. Your veterinarian will perform an electrocardiogram on your dog to assess his heart rate and rhythm. He or she will review your dog's medical history and ask questions regarding your dog's recent activities, including drinking and urinating frequencies. Diagnostic tests will incl Continue reading >>

    Does acute DKA cause hyperkalemia, or is the potassium normal or low due to osmotic diuresis? I get the acute affect of metabolic acidosis on potassium (K+ shifts from intracellular to extracellular compartments). According to MedEssentials, the initial response (<24 hours) is increased serum potassium. The chronic effect occuring within 24 hours is a compensatory increase in Aldosterone that normalizes or ultimatley decreases the serum K+. Then it says on another page that because of osmotic diuresis, there is K+ wasting with DKA. On top of that, I had a question about a diabetic patient in DKA with signs of hyperkalemia. Needless to say, I'm a bit confused. Any help is appreciated.

    I remember this being a tricky point:
    1) DKA leads to a decreased TOTAL body K+ (due to diuresis) (increase urine flow, increase K+ loss)
    2) Like you said, during DKA, acidosis causes an exchange of H+/K+ leading to hyperkalemia.
    So, TOTAL body K+ is low, but the patient presents with hyperkalemia. Why is this important? Give, insulin, pushes the K+ back into the cells and can quickly precipitate hypokalemia and (which we all know is bad). Hope that is helpful.

    DKA-->Anion gap M. Acidosis-->K+ shift to extracellular component--> hyperkalemia-->symptoms and signs
    DKA--> increased osmoles-->Osmotic diuresis-->loss of K+ in urine-->decreased total body K+ (because more has been seeped from the cells)
    --dont confuse total body K+ with EC K+
    Note: osmotic diuresis also causes polyuria, ketonuria, glycosuria, and loss of Na+ in urine--> Hyponatremia
    DKA tx: Insulin (helps put K+ back into cells), and K+ (to replenish the low total potassium
    Hope it helps
