Acid load after intravenous aminoacid infusion: comparison of clorurated vs. acetated solutions.
Ten patients who underwent elective abdominal surgery were given a daily load of one liter of a 10% aminoacid solution randomly containing cationic aminoacid as clorure or acetate salt during the first four post-operative days. None of the patients developed acidosis but the mean daily urinary excretion of titratable acidity and ammonium ions was significantly higher in clorure treated patients. An aminoacid solution containing aminoacid as acetate acts as a sparing solution for tubular buffer activity, and therefore should be preferred for patients with tubular impairment.
