Anion gap metabolic acidosis
"MUDPILES" Methanol intoxication Uremia Diabetic or alcoholic ketoacidosis Paraldehyde Isoniazid or Iron overdose Lactic acid Ethylene glycol intoxication Salicylate intoxication
Non-anion gap metabolic acidosis
Renal tubular acidosis Diarrhea Gastrointestinal fistula Post-hyperventilation Post-anion gap acidosis
Vomitting
Metabolic alkalosis
Hypocholermic metabolic alkalosis is closely associated with Pyloric stenosis
An anion gap of greater than 12 is “increased”

If you determine that your patient has a primary metabolic acidosis (low pH with low HCO3), the next step is to calculate the anion gap because the anion gap helps you determine the etiology of the metabolic acidosis.
The anion gap is the difference between the measured serum cations (positively charged particles) and the measured serum anions (negatively charged particles). The commonly measured cation is sodium and the measured anions include chloride and bicarbonate.
Anion gap = [Na+] - ([Cl-] + [HCO3-])

Anion gap = [Na+] - ([Cl-] + [HCO3-])
Add Na - Cl + HCO3
