Metabolic alkalosis is a metabolic condition in which the pH of tissue is elevated beyond the normal range 7.
This is the result of decreased hydrogen ion concentration, leading to increased bicarbonateor alternatively a direct result of increased bicarbonate concentrations. The condition typically cannot last long if the kidneys are functioning properly.
Mild cases of metabolic alkalosis often causes no symptoms.
Typical manifestations of moderate to severe metabolic alkalosis include abnormal sensationsneuromuscular irritability, tetanyabnormal heart rhythms usually due to accompanying electrolyte abnormalities such as low levels of potassium in the bloodcomaseizuresand temporary waxing and waning confusion. The causes of metabolic alkalosis can be divided into two categories, depending upon urine chloride levels. Blood product administration since this contains sodium metbolique which is then metabolized into sodium bicarbonate.
Typically, this is seen with large volume transfusions such as more than 8 units. Decreases in albumin and phosphate will cause metabolic alkalosis.
Compensation for metabolic alkalosis occurs mainly in the lungs, which retain carbon dioxide CO 2 through slower metbaolique, or hypoventilation respiratory compensation. CO 2 is then consumed toward the formation of the carbonic acid intermediate, thus decreasing pH. Respiratory compensation, though, is incomplete. But, because respiration slows, there’s an increase in pCO 2 which would cause an offset of the depression because of the action of the central chemoreceptors which are sensitive to the partial pressure of CO 2 [ citation needed ] in the cerebral spinal fluid.

So, because of the central chemoreceptors, respiration rate would be increased. To calculate the expected pCO2 in the setting of metabolic alkalosis, the following equations are used:. To effectively treat metabolic alkalosis, the underlying cause s must be corrected. A trial of intravenous chloride-rich fluid is warranted if there is a high index of suspicion for chloride-responsive metabolic alkalosis caused by loss of gastrointestinal fluid e.
