Summary

A 65-year-old male patient with hypertension, diabetes, and chronic renal failure on hemodialysis presents for an elective left arm arteriovenous fistula grafting. The patient unfortunately missed his dialysis and his last K+ was 6.7 mEq/L. The patient is asymptomatic. What are your concerns? What tests and labs do you want? Would you postpone the surgery? Would you demand hemodialysis first? Would you be less concerned if the patient was not on dialysis? If this case suddenly became an emergency, what is your anesthetic plan?
