Abstract
Acute phase reactants (APR) were measured in 14 patients undergoing cardiopulmonary bypass. The levels of alpha 1 anti-trypsin(α1-AT) and sialic acid (SA) began to increase from 1st day after operation, and reached a peak within 3rd day after operation. Both levels were continuing highly until 14th day after operation. Immunosuppressive acidic protein (IAP) level showed a rapid increase just after operation and maintained the high level postoperatively. Alpha2-macroglobulin (α2-M) showed a change within normal range. C-reactive protein (CRP) showed a rapid increase as same as IAP, but it decreased rapidly from 7th day after operation. The measurements of APR can be a marker of the inflammatory stage and as a postoperative management.
