Abstract Introduction Multiple studies have shown a decrease in the inflammatory response with minimized bypass circuits leading to less complications and mortality rate. On the other hand, some other studies showed that there is no difference in post-operative outcomes. So, the aim of this study is to investigate the clinical benefits of using the Minimized cardiopulmonary Bypass system in Coronary Artery Bypass Grafting and its effect on postoperative morbidity and mortality in diabetic patients as one of the high-risk groups that may benefit from these systems. Methods This is a retrospective study that included 114 diabetic patients who underwent Coronary artery bypass grafting (67 patients with conventional cardiopulmonary bypass system and 47 with Minimized cardiopulmonary bypass system). The patients’ demographics, intra-operative characteristics and postoperative complications were compared between the two groups. Results Coronary artery bypass grafting was done on a beating heart less commonly in the conventional cardiopulmonary bypass group (44.78% vs. 63.83%, p = 0.045). There was no difference between the two groups in blood loss or transfusion requirements. Four patients in the conventional cardiopulmonary bypass group suffered perioperative myocardial infarction while no one had perioperative myocardial infarction in the Minimized cardiopulmonary bypass group. On the other hand, less patients in the conventional group had postoperative Atrial Fibrillation (4.55% vs. 27.5%, p = 0.001). The requirements for Adrenaline and Nor-Adrenaline infusions were more common the conventional group than the Minimized group. Conclusion The use of conventional cardiopulmonary bypass for Coronary Artery Bypass Grafting in diabetic patients was associated with higher use of postoperative vasogenic and inotropic support. However, that did not translate into higher complications rate or mortality.

Artery Bypass Grafting

Background and Aims: Cardiopulmonary bypass induces a systematic inflammatory response, which is partly understood by investigation of peripheral blood cytokine levels alone; the lungs may interfere with the net cytokine concentration. We investigated whether lung ventilation influences lung passage of some cytokines after coronary artery bypass grafting. Material and Methods: In total, 47 patients undergoing coronary artery bypass grafting were enrolled, and 37 were randomized according to the ventilation technique: (1) No-ventilation group, with intubation tube detached from the ventilator; (2) low tidal volume group, with continuous low tidal volume ventilation; and (3) continuous 10 cm H2O positive airway pressure. Ten selected patients undergoing surgery without cardiopulmonary bypass served as a referral group. Representative pulmonary and radial artery blood samples were collected for the evaluation of calculated lung passage (pulmonary/radial artery) of the pro-inflammatory cytokines (interleukin 6 and interleukin 8) and the anti-inflammatory interleukin 10 immediately after induction of anesthesia (T1), 1 h after restoring ventilation/return of flow in all grafts (T2), and 20 h after restoring ventilation/return of flow in all grafts (T3). Results: Pulmonary/radial artery interleukin 6 and pulmonary/radial artery interleukin 8 ratios ( p = 0.001 and p = 0.05, respectively) decreased, while pulmonary/radial artery interleukin 10 ratio ( p = 0.001) increased in patients without cardiopulmonary bypass as compared with patients with cardiopulmonary bypass. Conclusions: The pulmonary/radial artery equation is an innovative means for the evaluation of cytokine lung passage after coronary artery bypass grafting. The mode of lung ventilation has no impact on some cytokines after coronary artery bypass grafting in patients treated with cardiopulmonary bypass.

Background Coronary artery bypass grafting (CABG) without cardiopulmonary bypass (off-pump CABG) may reduce severe adverse events including stroke. Methods In the German Off-Pump Coronary Artery Bypass Grafting in Elderly patients trial, the rate of major adverse cardiovascular events was compared in 2,394 elderly (≥ 75 years) patients undergoing CABG with (on-pump) or without (off-pump) cardiopulmonary bypass. This exploratory post-hoc analysis investigated the impact of surgical aortic manipulation on the rate of stroke. Results There was no significant difference in the rate of stroke within 30 days after surgery between both groups (off-pump: 2.2%; on-pump: 2.7%; odds ratio [OR]: 0.83 [0.5–1.38]; p = 0.47). Within the off-pump group, different degrees of aortic manipulation did not lead to significant different stroke rates (tangential clamping: 2.3%; OR 0.86 [0.46–1.60]; clampless device: 1.8%; OR 0.67 [0.26–1.75]; no aortic manipulation: 2.4%; OR 0.88 [0.37–2.14]). An aggregate analysis including more than 10,000 patients out of the four recent major trials also yielded comparable stroke rates for on- and off-pump CABG (off-pump: 1.4%; on-pump: 1.7%; OR 0.87 [0.64–1.20]). Conclusion Within recent prospective randomized multicenter trials off-pump CABG did not result in lower stroke rates. The possible intrinsic benefit of off-pump CABG may be offset by the complexity of the operative therapy as well as the multiple pathomechanisms involved in perioperative stroke.
