To report a case of high anion gap metabolic acidosis related to infusion of aminocaproic acid aca that temporarily corrected during hemodialysis and resolved upon aca discontinuation. The causes of metabolic acidosis may be divided into those associated with a normal anion gap hyperchloremic metabolic acidosis and those associated with an increased anion gap normochloremic metabolic acidosis box Unmeasured anions are frequently elevated in critically ill patients with normal elfvado.

Our analysis demonstrates that AGCAPL is highly correlated with SIG in a mixed sample of critically ill patients and that such correlation is independent of the presence of metabolic acidosis.
