HyperKalemia - Potassium increase - Causes, level, diagnosis and Rx:
Hyperkalemia - increase in the level of potassium Causes, level, diagnosis and Rx: s-K> 5.5mmol/l requires emergency management: ECG, repeat bloods, stop exogenous potassium and potassium retaining medications Assess potential causes of transcellular shift estimate the GFR Drugs: ACE inhibitors, Potassium sparing drugs, digitalis toxicity (blocks the Na/K ATPase, Succinylcholine, B-Blockers Potassium Supliments - Potassium Chloride suppliments or KCl IVI PEN G - antibioltics Breakup of cells: Rhabdomyolysis, tumour lysis syndrome, Hemolysis - the intracellular K leaks out to the extracellular space - increasing potassium in the blood Metabolic Acidosis (except for keto and lactic acidosis) and Insulin deficiency - DKA - both acidosis and insulin deficiency Potassium can not be excreated decreased GFR renal failure decreased effective circulating volume NSAID in renal insufficiency HYPOALDOSTERONISM Causes of Hyerkalemia with Normal GFR Low renin and low
