a Perioperative blood CK and glucose levels during off-pump CABG. The CK levels increased to a maximum value of 2328 U/L on POD 2. Insulin administration was initiated when the blood glucose levels exceeded 200 mg/dL and continued until POD 3. CHDF was performed between PODs 4 and 25. b Perioperative blood CK and glucose levels during laparoscopic cholecystectomy. The CK levels slightly increased on PODs 2 and 3 with a continuous glucose infusion rate of 4 mg/kg/h and intermittent administration of intravenous insulin; however, there was no acute renal failure. CK, creatine kinase; CABG, coronary artery bypass grafting; POD, postoperative day; CHDF, continuous hemodiafiltration
