Estimate serum sodium concentration changes in patients, particularly those with hypertriglyceridemia, using our intuitive calculator. Predict the impact of administered intravenous fluids on fluid balance and electrolyte levels. Essential for clinical decision-making and managing hyponatremia or hypernatremia risks.
Formula:
Total Body Water (TBW) = Patient Weight (kg) × Gender-specific Factor
(Factor: 0.6 for men, 0.5 for women)
New Serum Sodium = ( (Infusate Sodium (mEq/L) × Infusate Volume (L)) + (Current Serum Sodium (mEq/L) × TBW (L)) ) ÷ ( TBW (L) + Infusate Volume (L) )
Sodium Change = New Serum Sodium - Current Serum Sodium
