title: [Effect of clamping of portal vein on serum potassium level during hepatic resection].
abstract: We studied relation between the serum potassium changes and the factors affecting serum potassium level during hepatic resection in 23 patients. Serum potassium concentration became significantly higher after hepatic resection. The magnitude of increase in serum potassium concentration showed a correlation with total clamping time of the right or left portal vein (r = 0.576, P less than 0.01) and also with the amount of blood transfused (r = 0.441, P less than 0.05), but no significant correlation was found with fall in pH and urine output during hepatic resection. These results suggest that the duration of clamping of portal vein play the key role in the increment in serum potassium concentration during hepatic resection.
