[Changes in catecholamine and immunoglobulin during anesthesia for cardiac surgery--a comparison of valve replacement and aorto-coronary bypass surgery].

| Abstract |
During a period of extracorporeal circulation, which represents a massive invasion for the body, the patient is in a state of controlled shock. In this study, we examined changes in catecholamines and immunoglobulins in patients grouped according to whether they underwent valve replacement or aorto-coronary bypass surgery. Anesthesia was induced with fentanyl, and cardiopulmonary bypass in all patients was carried out using a bubble-type heart-lung machine. The epinephrine and norepinephrine levels increased during the procedures, but those patients having aorto-coronary bypass surgery showed milder rises than valve replacement patients. IgA, IgG and IgM all dropped as well, but the change in IgG was the greatest, and the decreases were more marked in valve replacement patients than in aorto-coronary bypass patients. It was concluded that, since reactions were different according to the disorder present and were reflected in the variations in catecholamine and immunoglobulin levels, great care is necessary when the patient is removed from the heart-lung machine.
