Hyperkalaemia In Adults

Patient professional reference Professional Reference articles are written by UK doctors and are based on research evidence, UK and European Guidelines. They are designed for health professionals to use. You may find the Dietary Potassium article more useful, or one of our other health articles. Description Hyperkalaemia is defined as plasma potassium in excess of 5.5 mmol/L[1]. The European Resuscitation Guidelines further classify hyperkalaemia as: Mild - 5.5-5.9 mmol/L. Moderate - 6.0-6.4 mmol/L. Severe - >6.5 mmol/L. Potassium is the most abundant intracellular cation - 98% of it being located intracellularly. Hyperkalaemia has four broad causes: Renal causes - eg, due to decreased excretion or drugs. Increased circulation of potassium - can be exogenous or endogenous. A shift from the intracellular to the extracellular space. Pseudohyperkalaemia. Epidemiology The time of greatest risk is at the extremes of life. Reported incidence in hospitals is 1-10%, with reduced renal function causing a five-fold increase in risk in patients on potassium-influencing drugs[2]. Men are more likely than women to develop hyperkalaemia, whilst women are more likely to experience hypokalaemia. R Continue reading >>

    What are the potassium level abnormalities associated with DKA (during diagnosis and treatment.)

  2. ahassan

    During DKA, the total body K is low bcz of osmotic diuresis, BUT the serum k conc. is raised bcz of the lack of insulin action, which allows k to shift out of the cells. So hyperkalemia.
    During treatment, k is shifted into the cells, which may lead to profound hypokalemia n death if not treated, so during therapy you have to adjust KCL conc. depending on blood K levels.

    In DKA--> K level may be high or normal so we dont add k from the start of ttt
    But : In HHNKC---> K level is low from the start so we give k from start of ttt
