Postoperative potassium deficit and metabolic alkalosis.

Effect of amiloride on metabolic alkalosis and hypokalaemia after cardiopulmonary bypass surgery.

This study was undertaken to investigate the effects of the potassium-retaining diuretic, amiloride, on the potassium balance and on the alkalosis which occurs in patients after open-heart surgery. Patients who had had valve replacement operations were divided randomly into two groups, one of which received Io mg amiloride daily in the postoperative period. Patients who were given amiloride nee...

Renal potassium handling in a patient with surreptitious vomiting.

Sir, We read with great interest the recently published Teaching Point ‘The tell-tale urinary chloride’ w1x. While differential diagnosis of this intriguing case was properly managed, focusing on urinary chloride concentration and the coexisting metabolic alkalosis, the teaching points reported are not clearly stated. Concerning the first point: we should note that gastric losses were unlikely ...

The induction of metabolic alkalosis by correction of potassium deficiency.

High incidence of postoperative metabolic alkalosis in surgical patients.

A retrospective study was undertaken to elucidate the changes of acid-base balance following general surgery. 2843 samples of arterial blood gas and pH determinations were obtained from 418 surgical patients before and after the operation. Before the operation, the incidence of acid-base disturbance was low, 79.5% of 190 determinations being normal in acid-base balance. During the postoperative...
