Introduction:Cardiopulmonary bypass surgery is accompanied by an inflammatory response and pulmonary dysfunction that renders patients vulnerable to postoperative complications. The majority of studies investigating the inflammatory response in cardiopulmonary bypass focus on cytokine measurements. This study investigated the early response of peripheral blood cell types and early changes in lung tissue in on-pump versus off-pump cardiopulmonary bypass surgery.Methods:Landrace pigs were assigned to the following groups (n = 6 per group): 1. off-pump cardiopulmonary bypass, 2. conventional cardiopulmonary bypass, 3. heparin-coated cardiopulmonary bypass, 4. surface-reduced cardiopulmonary bypass, and 5. surface-reduced cardiopulmonary bypass plus lung perfusion. Surgery was performed under mild hyperthermia (32°C), with 90-minute ischemia and 180-minute reperfusion. Histological and flow cytometric analyses were performed.Results:Lung water content increased during reperfusion in heparin-coated (84.63 ± 2.99%) compared to conventional cardiopulmonary bypass (76.33 ± 4.56%, p = 0.04). Alveolar septal thickness increased during ischemia at heparin-coated (p < 0.01) and surface-reduced cardiopulmonary bypass plus lung perfusion (p = 0.05). Tumor necrosis factor expression increased significantly (p < 0.01) in peribronchial, perivascular, and peripheral lung areas in all on-pump groups, but not in off-pump cardiopulmonary bypass. The usage of heparin-coated cardiopulmonary bypass led to increased percentages of CD3+CD4+(p = 0.03) and CD3+CD8+(p = 0.01) T cells compared to an uncoated device. Natural killer and mature B lymphocytes decreased at conventional and surface-reduced cardiopulmonary bypass plus lung perfusion. Activated granulocytes and macrophages increased at conventional cardiopulmonary bypass and heparin-coated cardiopulmonary bypass.Conclusion:Off-pump cardiopulmonary bypass induces less immunological response and lung injury than on-pump surgery. The reduction of cardiopulmonary bypass surface reduces the inflammatory immune response induced by cardiopulmonary bypass. Lung perfusion of surface-reduced cardiopulmonary bypass diminished the extravasation caused by surface reduction of the cardiopulmonary bypass.

Purpose: Cardiopulmonary bypass (CPB) is commonly associated with a systemic inflammatory response that may lead to severe complications. Classic signs of systemic inflammatory response syndrome are complement activation and changes in cytokine and acute phase reactant levels. The effects of rosuvastatin after CPB on interleukin-6 (IL-6), interleukin-10 (IL-10), interleukin-18 (IL-18) and High Sensitivity C-Reactive Protein (hs-CRP) levels were investigated. Methods: Thirty-seven male and thirteen female patients (total=50) aged 42 to 78 years, who had coronary bypass surgery due to coronary artery disease were randomly divided into two groups. The 25 patients in the control group were administered placebos. The 25 in the treatment group were administered 20 mg rosuvastatin tablets daily between preoperative day 7 and postoperative day 28. Blood samples were taken at six time points; before induction of anesthesia (T1), during CPB (T2), five minutes after removal of cross clamp (T3), after protamine infusion (T4), postoperative day three (T5) and postoperative day 28 (T6). Data points were expressed as mean ± standard deviation (SD). Results: Rosuvastatin lowered IL-6 levels at T4, T5 and T6 time points (T4, T5, T6 p < 0.05), and elevated IL-10 levels at T3 and T4 (T3, T4 p < 0.05). IL-18 levels were also elevated at multiple time points. Rosuvastatin also lowered hs-CRP levels and cholesterol levels at T6 (p < 0.05). Conclusion: Administering 20 mg/day of rosuvastatin between preoperative day 7 and postoperative day 28 may result in fewer complications in certain (especially intraoperative) cases of systemic inflammatory response caused by the CPB technique used in coronary bypass surgery.
