Electrolyte Correction Reference

Na, K, Ca, Mg, PO₄ Quick Reference

1 What is the Electrolyte Correction Reference?

Electrolyte Corrections is an in-app clinical reference for the treatment and work-up of common paediatric electrolyte disturbances — hyper- and hypocalcaemia, hyper- and hyponatraemia, hyper- and hypokalaemia, hypoglycaemia, hypomagnesaemia, and hypophosphataemia. Each disturbance card lists first-line treatment options and a relevant diagnostic work-up, and where applicable links directly to PediAid's own correction calculators, such as free water deficit, sodium correction, and potassium correction. Per the source, every value on the card is a verbatim transcription, and the guide is intended for use by qualified clinicians only.

2 When to use it

  • Quickly reviewing first-line treatment options for a specific electrolyte disturbance at the bedside
  • Identifying the appropriate diagnostic work-up to determine the cause of an electrolyte abnormality
  • Jumping directly from a disturbance summary into the matching PediAid calculator, such as sodium or potassium correction
  • Cross-checking adjunct therapies such as albumin, bicarbonate, and THAM dosing formulas
  • Reviewing linked diagnostic calculators such as anion gap, serum osmolality, and corrected sodium for hyperglycaemia

3 Formula & method

This is a structured reference card rather than a single calculator — it lists treatment and work-up bullet points for nine electrolyte disturbances, plus adjunct correction formulas transcribed from the source, such as the free water deficit formula "FWD = 0.6 (wt) ([Na]/140 − 1)" and the sodium deficit formula "Na deficit (mEq) = (Na_goal − Na_meas) × wt × 1.2." Each disturbance section links out to a matching interactive calculator elsewhere in the app (e.g., Sodium Correction, Potassium Correction, Calcium Correction, Magnesium Correction, Phosphate Correction, Free Water Deficit, Dextrose Bolus) for the actual computation.

4 Frequently asked questions

What electrolyte disturbances does this reference cover?

Hypercalcaemia, hypocalcaemia, hypernatraemia, hyponatraemia, hyperkalaemia, hypokalaemia, hypoglycaemia, hypomagnesaemia, and hypophosphataemia.

Does this guide perform calculations itself?

The guide itself is a treatment and work-up reference; calculations are performed by the linked calculator tools it points to, such as sodium correction, potassium correction, and free water deficit calculators.

What formula does the guide give for free water deficit?

It states "FWD = 0.6 (wt) ([Na]/140 − 1)" alongside the rule of thumb "4 mL FW/kg = ↓ Na 1 mEq/L."

What work-up does the guide suggest for hyponatraemia?

It lists urine and serum osmolality, urinalysis, urine electrolytes, CMP, lipids, and water restriction if SIADH is suspected.

What other diagnostic calculators does this guide link to?

Anion Gap, Serum Osmolality, and Corrected Sodium (for hyperglycaemia) calculators are listed as "Linked diagnostic calculators."
