AB A case of lactic acidosis presented the opportunity for review of the association between lactic acidosis and ketoacidosis. The diagnosis of lactic acidosis or the combination of lactic acidosis and ketoacidosis is established clinically by the detection of a metabolic acidosis of the "unmeasured anion gap" type in the absence of significant renal failure, poison intake or a strongly positive clinical test for ketones. Before treatment can be planned the biochemical basis of lactic acidosis and ketoacidosis must be understood -- especially the fact that lactic acidosis is not a single disease entity but has many possible causes. Among important considerations is the relation between the blood concentrations of bicarbonate and organic acid anions. After recovery from metabolic acidosis of the unmeasured anion gap type, metabolic alkalosis is common. Decreased bicarbonate excretion plays an important role in the pathogenesis of the latter and may be the result of potassium or chloride loss, or both. The deficits, if present, should be corrected with appropriate therapy.
