체외순환 개심술 환자의 혈청 및 뇨중 Amylase 변동에 관한 연구

A study on the amylase in serum and urine in open heart surgery under the extracorporeal circulation

During the period of March 1981 to September 1982 a series of survey has been done on the value of amylase in blood and urine of 24 patients who went through the operation of heart surgery, for congenital and acquired heart diseases, with extracorporeal circulation at the Department of Thoracic _ Cardiovascular Surgery, School of Medicine, Hanyang University. In order to analyze the iteration and inter-relation of the value of amylase in blood and urine and the extra corporeal circulation time. The duration of extra-corporeal circulation time up to 60 minutes was classified as Group A while above 60 minutes was classified as Group B. The results are as follow; 1. 3 patients [23.07%] among 13 patients of Group A and 3 patients [27.27%] among 11 patients, showed increased amylase value after the surgery. 2. The average value in blood after operation was 120.3190.71 unit in Group A and 130.90113.15 unit in Group B. It was 11.59 units [9.63%] higher in Group A than in Group B. 3. 1 patient [7.7%] among 13 patients of Group A and 2 patients[18.18%] among 11 patients of Group B, the frequency of Group B was 10.48% higher. 4. The average Value of amylase in urine after the surgery was 111.9254.87 unit in Group A and 151.54111.17 unit in Group B. It was 39.62 unit [32.72%] higher in Group A than in Group B. 5. The longer the duration of extra corporeal circulation time showed the higher the amylase value in blood and urine after the operation. 6. Although the value of amylase in blood and urine was increased after operation, no patients Were found to have developed clinical pancreatitis.
