[Anesthetic management of exploratory laparotomy for a patient with panperitonitis with hyperkalemia: a case report of spontaneous rupture of the urinary bladder].

A 71-year-old woman was admitted with panperitonitis, hyperkalemia and acute renal failure. Immediately after a large amount of ascites had been drained by laparotomy, hyperkalemia and acidosis were remarkably improved. During the operation, rupture of the urinary bladder was detected and repaired. The level of potassium and renal function became normal the next morning, and it seemed that peritoneal-self-dialysis had been related to hyperkalemia and acute renal failure. Rupture of the urinary bladder is very rare but should be considered in any cases of acute abdomen with hyperkalemia and acute renal failure.
