Primary aldosteronism with uncommon complications

Abstract

In a patient who had primary aldosteronism and severe total body potassium depletion muscular tonic contractures developed during induction of anesthesia. After correction of the potassium deficit, the patient underwent uneventful anesthesia and transabdominal right adrenalectomy. Neither serum potassium level nor EKG seems to provide a reliable index of correction of potassium deficit. Measurement of potassium balance provided a method of quantitating the potassium depletion and of determining when the potassium deficit had been corrected. Balance studies should be utilized preoperatively when longterm potassium loss is suspected to reduce complications secondary to hypokalemia.
