|Patient UK||Hyperchloremic acidosis|
Hyperchloremic acidosis is a form of metabolic acidosis associated with a normal anion gap, a decrease in plasma bicarbonate concentration, and an increase in plasma chloride concentration (see anion gap for a fuller explanation). Although plasma anion gap is normal, this condition is often associated with an increased urine anion gap, due to the kidney's inability to secrete ammonia.
In general, the cause of a hyperchloremic metabolic acidosis is a loss of base, either a gastrointestinal loss or a renal loss.
- Gastrointestinal loss of bicarbonate (HCO3)
- Renal causes
- Other causes
- Ingestion of Ammonium chloride, Hydrochloric acid, or other acidifying salts.
- The Treatment and Recovery phase of diabetic ketoacidosis.
- Volume resuscitation with 0.9% Normal Saline provides a chloride load such that infusing more than 3-4L causes acidosis.
- Hyperalimentation fluids (i.e., total parenteral nutrition)
- DDB 11673
- NIH - Renal Tubular Acidosis
