Sodium Correction Rate in Hyponatremia
Calculates recommended fluid type, rate and volume to correct a patient's hyponatremia slowly (or more rapidly if seizing).
*Experts recommend correcting no faster than 12 mmol/L/day (0.5mmol/L/hr) to avoid central pontine myelinolysis (first calculation), and only correcting it faster — and only using hypertonic (3%) saline — if the patient is seriously symptomatic at a rate of 1-2 mmol/L/hr (second/third calculations), and even then, only correcting it at 1-2 mmol/L/hr for <3 hours.
- Change in Serum Sodium = (Fluid Sodium - Serum Sodium) / (Total Body Water + 1)
- Total Body Water = (Wt in kg * % Water)
