Abstract

Background: Intracellular and serum potassium levels have important effects on homeostasis cardiovascular system. Patients undergoing cardiac surgery may develop perioperative hypokalemia. Electrocardiographic (ECG) manifestations of hypokalemia include flattening of the T wave followed by T wave inversion, ST wave depression, prominent U wave, prolongation of the QTc interval, torsades de pointes, to asystole. Case Presentation: In this case report, a patient with coronary heart disease who underwent coronary artery bypass surgery, with moderate to severe hypokalemia, before surgery to postoperative care in the ICU. Management of hypokalemia in this patient using potassium chloride 10-50meq/hour (total 250 meq). Conclusion: Establishing a diagnosis, looking for underlying disease related to hypokalemia, and a history of preoperative medication should also be considered. Optimal conditions preoperatively can reduce morbidity and mortality. Appropriate management of severe hypokalemia should be known to all medical personnel. Periodic monitoring of ECG and potassium levels is necessary.
