The most common cause of normal anion gap acidosis is diarrhea with a renal tubular acidosis being a distant second. A normal anion gap is typically < 12. We respect your privacy. A less successful (and admittedly less useful) mnemonic exists for non-anion gap metabolic acidoses (NAGMA), which I learned as a resident. Ethylene glycol may cause renal failure with an elevated creatinine contributing to the AG metabolic acidosis, while both methanol and ethylene glycol may cause an elevated lactate.

A pH less than 7.35 is consistent with acidosis (acid). electrolytes). Diuretics. Ethylene glycol may cause renal failure with an elevated creatinine contributing to the AG metabolic acidosis, while both methanol and ethylene glycol may cause an elevated lactate. CAGE. If the Excess Gap Calculation comes to less than the normal range for Bicarbonate (22 – 28), then there is a third acid base disorder in the form of a Normal Anion Gap Metabolic Acidosis (NAGMA) Of course, NAGMA and Metabolic Alkalosis can be Stand-alone Disorders 4 but normal anion gap is maintained between sodium, chloride and bicarbonate concentrations. Normal Anion Gap Metabolic Acidosis (NAGMA), REASONS WHY ANION GAP MAY BE NORMAL DESPITE A ‘HIGH ANION GAP METABOLIC ACIDOSIS’. Urinary anion gap can be used to differentiate between gastrointestinal and renal causes for the normal anion gap metabolic acidosis.

See Terms of Service and Privacy Policy above for more detail. Metabolic acidosis is due to alterations in bicarbonate, so the pCO2 is less than 40 since it is not the cause of the primary acid-base disturbance. Two main causes of NAGMA are: Diarrhea, which will have a negative urine anion gap (Urine Na + Urine Potassium) – Urine Chloride. - Free lectures that make medical topics easy to understand, - Free animations and videos that correspond with each lecture, - Free mnemonics, tricks, and strategies to learn and remember the content, - Help to improve your exam scores and classroom performance, - Continued medical education for your career.

In a healthy normal individual, the main unmeasured anions are albumin and phosphate. Patient has an anion gap metabolic acidosis, but the decrease in bicarbonate is much greater than the elevation in anion gap (indicating the combination of an anion-gap metabolic acidosis plus a non-anion-gap metabolic acidosis).
