Metabolic alkalosis defined by the increase of both plasma hco3 level 26 mmoll and blood arterial ph 7. It can occur due to decreased blood levels of carbon dioxide, which is an acid. This is the result of decreased hydrogen ion concentration, leading to increased bicarbonate, or alternatively a direct result of increased bicarbonate concentrations. Based on these investigations, different approaches have been developed. Guidelines for the management of metabolic acidosis by dr. It can also occur due to increased blood levels of bicarbonate. Metabolic alkalosis is a metabolic condition in which the ph of tissue is elevated beyond the normal range 7. Depending on the anion gap ag is classified as elevated ag metabolic acidoses or normal ag me tabolic acidoses hyperchloraemic acidosis. Alkalosis occurs when your body has too many bases. If it is decided to administer bicarbonate, the sbe and the size of the treatable space are used to calculate the dose required. Primary metabolic alkalosis may occur from various causes including.
Hypochloremic metabolic alkalosis or strong ion alkalosis. Metabolic alkalosis is a a primary acidbase disorder that causes the plasma bicarbonate to rise to an abnormally high level. Clresistant metabolic alkalosis is due to increased aldosterone effect so management involves the correction of hyperaldosteronism. Symptoms and signs in severe cases include headache, lethargy, and tetany.
Common causes include prolonged vomiting, hypovolemia, diuretic use, and hypokalemia. Metabolic alkalosis is a primary increase in serum bicarbonate hco. Alkalosis is usually divided into the categories of respiratory alkalosis and metabolic alkalosis or a combined respiratorymetabolic alkalosis. Guidelines for the management of metabolic alkalosis by dr. Ba sed on this classification, it may establish the most appropriate treatment. Metabolic alkalosis endocrine and metabolic disorders. Galla division of nephrology and hypertension, department of internal medicine, university of cincinnati college of medicine, cincinnati, ohio. Metabolic alkalosis is commonhalf of all acidbase disorders as described in one study 1.
Metabolic alkalosis is primary increase in bicarbonate hco 3. The best measure of the level of metabolic acidosis is the standard base excess sbe because it is independent of pco 2. The condition typically cannot last long if the kidneys are functioning properly. Metabolic alkalosis is a type of alkalosis that occurs when your blood becomes overly alkaline. Paco2 ni, hco3 paco2 acute respiratory alkalosis compensation hco3. Pathologic causes of respiratory alkalosis include various hypoxemic conditions, pulmonary disorders, central nervous system diseases, pharmacologic or. Alkalosis is the result of a process reducing hydrogen ion concentration of arterial blood plasma alkalemia.
