Abstract:
Three patients developed unaccountable hyperkalemia during general anesthesia for pancreatectomy, hepatectomy, and cholangio-jejunostomy. The patients had normal preoperative renal function, serum potassium values, and intraoperative urine output. The surgical manipulations might have reduced portal venous and/or hepatic arterial blood flow resulting in the hepatic ischemia. Consequently, hepatic intra-cellular potassium might have leaked into the blood causing hyperkalemia. Anesthesiologists should be aware of the potential risk of hyperkalemia caused by surgical interventions on the liver and/or pancreas.
