[Changes of selected immunological parameters after cardiopulmonary bypass in postop period].
The aim of the study was to evaluate the influence of changes of chosen immunological parameters on postoperative course patients after cardiopulmonary bypass operation. Complement components C3, C4 and immunoglobulins IgA, IgG, IgM were taken into account. The group consisted of 70 patients, 51 men at mean age 52.6 +/- 10.8 years and 19 women at mean age 50.7 +/- 11.0 years. All patients were operated in moderate hypothermia 26-32 degrees C with use of crystalloid cardioplegia. We used membrane oxygenators: Safe II (Polystan), Monolyth (Sorin), Maxima (Medtronic) and Bentley (Baxter). In 36 patients with multivessel coronary artery disease the internal thoracic artery and saphena vein grafts were performed. 27 patients underwent the valve prosthesis implantation procedure and 7 correction of the congenital heart dis-ease. The mean extracorporeal perfusion time was 127.5 +/- 51.0 min. The mean aortic cross-clamping time was 65.6 +/- 26.9 min. 6 blood samples were taken in the time periods called from 0 to 5: 0--before the operation, 1--right after the operation, 2--1 day after the operation, 3--3 days after the operation, 4--7 days after the operation, 5--14 days after the operation. All the immunological parameters were measured at the Technicon RA-1000 System device using plasma antibody serum of Behring Company. We compared two groups: 1) 21 patients extubated at operation day with 42 patients extubated at 1-th postoperative day, 2) 38 patients with postoperative organ failure with 32 patients without organ complications. The intubation time was shorter in patients with higher levels of C3 (to 7-th day) and C4 (at 1-th postoperative day). The postoperative organ failure were more frequently in patients with lower postoperative C3 (to 3-th day) and with lower C4 at 1-th postoperative day. The postoperative changes of immunoglobulins IgA, IgG, IgM were similar in patients with complicated and uncomplicated postoperative course.
