Answer

Intravenous HCl is indicated in severe metabolic alkalosis (pH >7.55) or when sodium or potassium chloride cannot be administered because of volume overload or advanced renal failure. HCl may also be indicated if rapid correction of severe metabolic alkalosis is warranted (eg, cardiac arrhythmias, hepatic encephalopathy, digoxin cardiotoxicity). [18] Seek the advice of a nephrologist when severe alkalosis is present and HCl therapy or dialysis is contemplated.
