Sodium bicarbonate injection is indicated for the treatment of metabolic acidosis that occurs in severe renal disease, uncontrolled diabetes, circulatory insufficiency due to shock or severe dehydration, extracorporeal circulation of blood, cardiac arrest, and severe primary lactic acidosis.
It is also indicated for the treatment of certain drug intoxications (including barbiturates, poisoning by salicylates or methyl alcohol, and in hemolytic reactions requiring alkalinization of the urine to diminish nephrotoxicity of blood pigments), and severe diarrhea which is often accompanied by a significant loss of bicarbonate.
