Sodium Correction Rate Calculator
Adrogue-Madias formula for hyponatraemia correction with hypertonic (3%) or isotonic saline. Built-in CPM (central pontine myelinolysis) safety caps. For internists, intensivists and nephrologists.

★ DoctorScribe — Complete Clinic Management
Stop juggling spreadsheets in the ICU
DoctorScribe auto-plots electrolyte trends, computes Adrogue-Madias on every Na draw, alerts on overshoot, and links to the prescribing chart — your ICU's electrolyte safety net.
Clinical Disclaimer: Adrogue-Madias is a starting estimate, NOT a substitute for serial Na monitoring (every 2-4 hours). Real responses vary because the formula ignores ongoing renal losses, ADH dynamics, and SIADH water clearance. Always cap correction at 8 mEq/L per 24h (10-12 mEq/L if proven acute <48h) to avoid osmotic demyelination. Always verify against your local prescribing reference and apply clinical judgment.
Run the ICU safer — fewer correction errors
DoctorScribe auto-tracks serum Na every 2-4h, computes Adrogue-Madias on each draw, alerts when correction is too fast, and logs every fluid order — your ICU's electrolyte safety net.
