Abstract:
Severe hyperkalemia can induce life threatening cardiac rhythm disturbances, and usually produce classic electrocardiographic (EKG) manifestations. We report a case of severe hyperkalemia in which the EKG did not reveal the expected alterations. The patient was a 57-year-old man with adenocarcinoma of stomach. There were no significant abnormal findings in laboratory analysis, chest X-ray and EKG. His preoperative medications for hypertension consisted of furosemide, amiloride and enalapril. The tests for serum potassium concentration ([K ]) were performed on 20 and 7 days before the operation and the results were 4.5 and 4.9 mEq/l, respectively. Just after induction of anesthesia, we tried the blood gas and electrolyte analysis and the result revealed high [K ] of 8.5 mEq/l, but EKG did not show typical phenotype of hyperkalemia at that time. His intraoperative and postoperative courses were not eventful.
