Episode notes
Simplified Anion Gap Calculation
- Keep anion gap calculation simple: sodium - bicarbonate - chloride.
- Skip potassium and albumin corrections for easier calculation.
Anion Gap Correction Ineffective
- Correcting anion gap for albumin doesn't improve diagnosis of lactic acidosis.
- Studies show similar sensitivity and specificity with or without correction.
Anion Gap Limitations
- A normal anion gap range is wide (4-12), allowing significant lactic acidosis to develop unnoticed.
- Don't rely solely on anion gap; measure lactate directly if concerned about lactic acidosis.
