Management of metabolic acidosis: does correction with sodium bicarbonate do more harm than good?
Summary of "Management of metabolic acidosis: does correction with sodium bicarbonate do more harm than good?"
Metabolic acidosis is a very common finding in critically ill patients and is associated with increased morbidity and mortality. Metabolic acidosis in critical care patients is commonly the result of either anaerobic metabolism or failure of excretion of endogenous acid. Other causes include renal or gastrointestinal loss of bicarbonate and the intake of exogenous acids.

Metabolic acidosis occurs when a relative accumulation of plasma anions in excess of cations reduces plasma pH. Replacement of sodium bicarbonate to patients with sodium bicarbonate loss due to diarrh...
Background: Metabolic acidosis is a common problem of patients on neonatal intensive care units. Only little data exists in literature and there are no clinical guidelines. The aim of this national su...
Administration of NaHCO3 does not improve cellular function or reduce the mortality of acute lactic acidosis. This might be related to aggravation of intracellular acidosis, but it could also be due t...
Concomitant severe metabolic alkalosis, hypernatremia and kidney failure pose a therapeutic challenge. Hemodialysis to correct azotemia and abnormal electrolytes results in rapid correction of serum s...
Urinary alkalinization with sodium bicarbonate infusion can theoretically protect against the mechanisms of acute kidney injury. Controversy exists regarding whether sodium bicarbonate infusion can re...

Medical and Biotech [MESH] Definitions
Proteins that cotransport sodium ions and bicarbonate ions across cellular membranes.
A congenital or acquired condition of insufficient production of ALDOSTERONE by the ADRENAL CORTEX leading to diminished aldosterone-mediated synthesis of Na(+)-K(+)-EXCHANGING ATPASE in renal tubular cells. Clinical symptoms include HYPERKALEMIA, sodium-wasting, HYPOTENSION, and sometimes metabolic ACIDOSIS.
The oxygen consumption level above which aerobic energy production is supplemented by anaerobic mechanisms during exercise, resulting in a sustained increase in lactate concentration and metabolic acidosis. The anaerobic threshold is affected by factors that modify oxygen delivery to the tissues; it is low in patients with heart disease. Methods of measurement include direct measure of lactate concentration, direct measurement of bicarbonate concentration, and gas exchange measurements.
Membrane proteins that allow the exchange of chloride ions for bicarbonate ions across the cellular membrane. The action of specific antiporters in this class serve important functions such as allowing the efficient exchange of bicarbonate across red blood cell membranes as they passage through capillaries and the reabsorption of bicarbonate ions by the kidney.
A pathologic condition resulting from accumulation of acid or depletion of the alkaline reserve (bicarbonate) content of the blood and body tissues, and characterized by an increase in hydrogen ion concentration (decrease in pH). (Dorland, 27th ed)
