Symptoms: hyperkalemia (nausea, vomiting, diarrhea, abdominal pain, metallic taste in the mouth, bradycardia, weakness, disorientation, muscle paralysis, paresthesia of the limbs, slowing of atrioventricular conduction, cardiac arrest)) and hypermagneemia (redness of the face, thirst, arterial hypotension, hyporeflexia, impaired neuromuscular transmission, respiratory depression, arrhythmia, convulsions).
Early clinical signs of hyperkalemia usually appear at a K + concentration in the serum of more than 6 meq / l: tapering of the T wave, disappearance of the prong U, segment decline S-T, interval elongation Q-T, expansion of the complex QRS. More severe symptoms of hyperkalemia - muscle paralysis and cardiac arrest - develop at a concentration of K + 9-10 meq / L.
Treatment: withdrawal of the drug, symptomatic therapy (iv administration of calcium chloride solution at a dose of 100 mg / min), if necessary - hemodialysis, peritoneal dialysis.
