Abstract

During cardiopulmonary by-pass and in the immediate postoperative period, serum potassium can change quite rapidly, usually tending to fall. Unless this deficit is corrected by potassium replacement at an appropriate rate there may be difficulty in defibrillating the heart in order to discontinue by-pass or there may be dangerous postoperative arrythmias. Frequent measurements of potassium should therefore be available for the safe management of these patients and improved techniques for their provisions are of great interest to the surgical teams responsible for the treatment of these patients.
