This raises the possibility of other causes of the high anion gap acidosis in this patient. Diabetic ketoacidosis, toxic alcohols, such as methanol and ethylene glycol, and salicylate intoxication could cause an anion gap metabolic acidosis of this severity (It should be noted, however, that, among patients with an identified organic acidosis, much of the excess anion gap cannot be explained by the measured anions, even after assiduous investigation (There were two important questions for the nephrology consultant to answer. A prospective, controlled clinical studySystemic effects of NaHCO3 in experimental lactic acidosis in dogsLactic acidosis: Effect of treatment on intracellular pH and energetics in living rat heartThe increase in CO2 production induced by NaHCO3 depends on blood albumin and hemoglobin concentrationsBinding of calcium to serum albumin. Peripheral hemoglobin oxygen saturation was 97% on room air, with a respiratory rate of 26 per minute. An endotracheal tube was inserted, and he was placed on mechanical ventilation. Free PMC article The patient was not hypotensive on arrival, and the peripheral oxygenation was normal. Mixed acid-base disorders are coded at E87.4. eCollection 2020.BMC Cardiovasc Disord. Thus, the accumulated lactate accounted for slightly over one half of the excess anion gap. Apart from tachypnea, he had normal vital signs and evidence of moderate fluid overload with vascular congestion.

Bodmer M, Meier C, Krähenbühl S, Jick SS, Meier CR.Diabetes Care. Public Library of Science In reality, there is considerable variability in the usual anion gap of a given individual (Initially, there was no mention of the high anion gap—clearly, an oversight. The apparent bicarbonate distribution space varies widely, however, and in inverse proportion to the bicarbonate concentration (Tris-hydroxymethyaminomethane is an amino alcohol that buffers without generating CORenal replacement therapy (RRT) offers a number of theoretical and practical advantages over alkali infusion for the treatment of lactic acidosis. He did meet several criteria for systemic inflammatory response syndrome, including rapid heart and respiratory rates and leukocytosis, but there was no obvious source of infection, and cultures of blood and urine proved later to be sterile. The treatment of lactic acidosis is controversial, except for the imperative to remedy its underlying cause. Abdellatif Aharaz has received a PhD stipendiate funded by The University of Southern Denmark and Nordic Bioscience via Danish PhD School of Endocrinology. Lactic acidosis occurs in one out of every 30,000 patients and is fatal in 50% of cases.
