2025 Multiprofessional Critical Care Review: Adult Online-Electrolyte Emergencies

Video Transcription

Video Summary

The talk comprehensively covers complex electrolyte emergencies, focusing on hyperkalemia, hyponatremia, calcium, phosphorus, and magnesium disorders, emphasizing recognition, underlying causes, symptoms, and management.<br /><br />Hyperkalemia, often from impaired kidney potassium excretion or cellular shifts, can cause cardiac arrhythmias and muscle weakness. Management includes membrane stabilization with calcium gluconate, shifting potassium intracellularly via insulin and glucose, beta agonists, and elimination through cation exchangers, diuretics, or dialysis. New agents like patiromer and sodium zirconium cyclosilicate show promise over older resins.<br /><br />Hyponatremia ranges from mild to severe neurological symptoms, with mortality linked to severity and correction rates. Proper diagnosis depends on serum osmolality and volume status. Avoiding rapid sodium correction prevents osmotic demyelination syndrome. Treatment varies by cause, including fluid restriction, IV fluids, diuretics, urea administration, and vasopressin receptor antagonists (vaptans) when refractory.<br /><br />Hypercalcemia needs volume repletion before loop diuretics to enhance calcium excretion, with dialysis in severe cases. Hypocalcemia, hypophosphatemia, and hypomagnesemia have diverse causes like malabsorption, cell shifts, and renal losses, presenting with neuromuscular and cardiac symptoms. Replacement must be cautious to avoid complications.<br /><br />Hypermagnesemia, often due to decreased excretion or excessive intake, notably in pregnancy, requires hydration, diuresis, or dialysis. IV calcium can temporize toxicity.<br /><br />Overall, understanding pathophysiology guides timely, tailored interventions to correct electrolyte imbalances and improve outcomes.
