Tag Fluids and Electrolytes
Fluids and electrolytes: Potassium wasting nephropathy
In this video Joel Topf looks at three types of potassium wasting nephropathies: Polyuria; distal RTA; and hypomagnesemia...and how each can lead to hypokalemia.
Fluids and electrolytes: Polyuria, polydipsia, and diabetes insipidus
In this video Joel Topf looks at how you can easily differentiate between different types of diabetes insipidus.
Fluids and electrolytes: Potassium-sparing diuretics
In this video Joel Topf looks at acetazolamide and potassium-sparing diuretics; how to optimise your patients’ diuretic regimen; the advantages and disadvantages of each diuretic; and what to do when they don’t work.
Fluids and electrolytes: Acute symptomatic hyponatremia
In this video Joel Topf looks at how the treatment algorithms for uncompensated hyponatremia differ based on the severity of symptoms.
Fluids and electrolytes: diuretic resistance
Diuretics don't always work as expected–what do you do when diuresis is not sufficient? In this video Joel Topf looks at how to alter treatment based on the pattern of diuretic response seen in your patient.
The Great Fluid Debate
John Myburgh hypothesises that resuscitation fluids cause more harm than they save lives.

Potassium
Potassium is the major intracellular cation (sodium is major extracellular). 90% is exchangeable, with an inverse relationship to serum pH
Hypokalaemia
Hypokalaemia: the most common electrolyte abnormality in hospitalised patients; mostly caused by drugs and GI disease
Hypernatraemia
Hypernatraemia can be caused by a number of critical illnesses: water depletion (decreased intake, hypotonic fluid loss – renal/non-renal); solute excess (Na+ or other)
Hyperkalaemia Management
Hyperkalaemia is a life-threatening emergency. Basic overview of hyperkalemia management
