Measuring HCO3 as part of an electrolyte or metabolic panel may also help diagnose acidosis or alkalosis. (2) diuretic therapy, most marked with vomiting due to pyloric stenosis or obstruction because the vomitus is acidic gastric juice only, vomiting in other conditions may involve a mixture of acid gastric loss and alkaline duodenal contents and the acid-base situation that results is more variable, diuretics such as frusemide and thiazides interfere with reabsorption of chloride and sodium in the renal tubules, urinary losses of chloride exceed those of bicarbonate, the patients on diuretics who develop an alkalosis are those who are also volume depleted (increasing aldosterone levels) and have a low dietary chloride intake (salt restricted diet), it is high while the diuretic is acting, but drops to low levels afterwards, potassium depletion occurs with mineralocorticoid excess, bicarbonate reabsorption in both the proximal and distal tubules is increased in the presence of potassium depletion, potassium depletion decreases aldosterone release by the adrenal cortex, the increased aldosterone levels lead to increased distal tubular Na+ reabsorption and increased K+ & H+ losses, increased H+ loss is matched by increased amounts of renal HCO3- leaving in the renal vein, the net result is metabolic alkalosis with hypochloraemia and hypokalaemia, often with an expanded ECF volume, the excess corticosteroids have some mineralocorticoid effects and because of this can produce a metabolic alkalosis, the alkalosis is most severe with the syndrome of ectopic ACTH production, cases have been reported of patients with metabolic alkalosis and severe hypokalaemia ([K+] < 2 mmol/l) due to severe total body potassium depletion, aetiology is not understood but correction of the alkalosis requires correction of the potassium deficit urinary chloride losses are high (>20mmol/l), syndrome of increased renin and aldosterone levels due to hyperplasia of the juxtaglomerular apparatus, an inherited as an autosomal recessive disorder usually found in children, the increased aldosterone levels usually result in a metabolic alkalosis, patients present with hypokalaemic alkalosis of uncertain cause are often suspected of having this condition but other causes which may be denied by the patient should be considered (eg surreptitious vomiting and/or use of diuretics for weight loss or psychological problems), rare genetic disorders such as Gitelmanns syndrome should also be considered, often associated with volume depletion (increased proximal tubular reabsorption of HCO3), respond to saline infusion (replaces chloride and volume), causes: previous diuretic therapy, vomiting, often associated with volume expansion and hypokalaemia, resistant to therapy with saline infusion, causes: excess aldosterone, severe K+ deficiency, diuretic therapy (current), Bartters syndrome, a high urinary chloride in association with hypokalaemia suggests mineralocorticoid excess, the urinary chloride/creatinine ratio may occasionally be useful as it is elevated if there is an extra-renal cause of alkalosis, impaired peripheral oxygen unloading (due shift of oxygen dissociation curve to left) hypoxaemia may occur and oxygen delivery to the tissues may be reduced, hypoventilation (due respiratory response to metabolic alkalosis), pulmonary microatelectasis (consequent to hypoventilation), increased ventilation-perfusion mismatch (as alkalosis inhibits hypoxic pulmonary vasoconstriction), the hypoventilation causes a compensatory rise in arterial pCO2 but the magnitude of the response has generally been found to be quite variable.
