Hyperkalaemia: a complication of warm heart surgery

YJ Kao, T Mian, S Kleinman and GB Racz
Department of Anesthesiology, Texas Tech University Health Sciences Center, Lubbock 79430.

A case is presented of hyperkalaemia (13.6 mEq.L-1) occurring during cardiopulmonary bypass using warm blood cardioplegia (K+ 40-60 mEq.L-1). Treatment with epinephrine, calcium chloride, sodium bicarbonate, and furosemide reduced K+ to 6.5 mEq.L-1 within 30 min and myocardial performance was enhanced with amrinone and cardiac rhythm was controlled with A-V segmental pacing. It is believed that the hyperkalaemia resulted from a combination of the surgical procedure (mitral valve replacement) and the use of warm cardioplegia. The purpose of this report is to increase the awareness of the possibility of hyperkalaemia with warm cardioplegia and to describe a successful therapeutic regimen.
