Potassium replacement during cardiopulmonary bypass
R Babka and R Pifarre
Sixty patients undergoing cardiopulmonary bypass (CPB) with the Travenol 6
L. variflow oxygenator bag and total hemodilution with Ringer's lactate
with 5 per cent dextrose were observed for their variances in potassium
(K+) levels and the degree of potassium replacement. We have seen that the
potassium level drops before CPB bypass in relation to the preadmission to
the operating room potassium level. During bypass the level rises and
following bypass it once again falls to be preceded by a rise after the
first 24 hour postoperative period...
