Cardiopulmonary bypass (CPB) necessary for valve replacements and coronary artery surgery is associated with various metabolic changes intraoperatively which we as anaethetists must understand to protect our patients. The aim of this review is to look at potassium changes intraoperatively during CBP. Potassium is the principal intracellular cation of our body that plays an important role in the excitability of vital cell membrane physiology, especially in cardiac muscles to maintain resting membrane potentials and cardiac conduction. Therefore, any extreme intraoperative K+ changes should be corrected to prevent arrhythmias that influence cardiac output and oxygen delivery intraoperatively.
