As stated previously, chloride and bicarbonate work together to maintain an ionic balance of the cellular space. It is expected to see an increase in respiratory rate as the body attempts to decrease CO2 in compensation, however, in long-standing disease this may lead to muscle fatigue and respiratory failure In every case of hyperchloremic acidosis, the primary treatment is aimed at identifying and treating the inciting event of pathology. The free water–associated changes and their influence on acid-base status are calculated in the sodium equation. Distal renal tubular acidosis is associated with amphotericin B, toluene, nonsteroidal anti-inflammatory drugs, and lithium use. 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 This occurs in patients with metabolic acidosis generated by profuse watery diarrhea. Results: Acidemia occurred rapidly and increased constantly up to a maximum value, which was reached in all calves by the end of the administration and amounted to a 22.4 mM/L mean base deficit (range from 17.0 to 33.1 mM/L). However, this will deplete bicarbonate stores leading to an acidotic state. Gastrointestinal loss of bicarbonate occurs through severe diarrhea, pancreatic fistula, nasojejunal tube suctioning from the duodenum, and chronic laxative use Normally, there is a degree of bicarbonate secreted into the intestinal lumen to allow for neutralization of the acidic environment of food from gastric emptying. Failure to manage the primary condition can lead to a high morbidity and mortality The human body experiences 2 main types of acidotic disorders: metabolic acidosis and respiratory acidosis.

[The occurrence of hyperchloremic acidosis in the saline group, although consistent with the anecdotal experience of clinicians who have infused large volumes of saline intraoperatively, [Curiously, the general concept of hyperchloremic acidosis was infrequently discussed in the anesthesiology literature before 1994. N Engl J Med 1977; 297:814-7Figge J, Jabor A, Kazda A, Fencl V: Anion gap and hypoalbuminemia. A normal serum anion gap is measured to be 8 to 16 mEq/L. This excess bicarbonate is ultimately lost in stools. It is vital to rule out any medication causing the acidosis. This Editorial View accompanies the following article: Scheingraber S, Rehm M, Sehmisch C, Finsterer U: Rapid saline infusion produces hyperchloremic acidosis in patients undergoing gynecologic surgery. Urine anion gap is calculated:Where Na is urine sodium, K is urine potassium, and Cl is urine chloride. In the presence of an acute decrease in serum albumin, the anion gap should be decreased proportionately; if it is not, other causes of metabolic acidosis should be considered.Rebecca Terry White Distinguished Chair; Department of Anesthesiology;Professor and Chief; Section on Pulmonary Medicine and Critical Care; Department of Medicine; The University of Texas Medical Branch; Galveston, Texas 77555–0591
Clin Kidney J. [A brief review of the key observations of this study is necessary to appreciate its importance. However as acidosis worsens stupor, coma, myocardial instability or arrest may occur. Additionally, electrolytes need to be monitored and replenished as applicable. An assumption, based in part on the Stewart approach to acid-base interpretation, [The most important question posed by this study is whether these data should prompt any alteration in clinical management. Anesthesiology 1996; 84:482-3Adrogue HJ, Wilson H, Boyd AE III, Suki WN, Eknoyan G: Plasma acid-base patterns in diabetic ketoacidosis. The key is to manage the primary condition causing the hyperchloremic acidosis. Hyperventilation of the patient on ventilator control can help reduce the acid load.

Hyperchloremic acidosis symptoms depend on the underlying disease or condition. Of specific importance is the potassium level. Aggressive attempts to improve organ perfusion, based on misdiagnosis of lactic acidosis, could prove harmful. Treatment of acute non-anion gap metabolic acidosis. Failure to secrete hydrogen directly correlates with the NH4 levels in urine and is able to be deduced via a positive urine anion gap as above.
