Abstract
Cardiopulmonary bypass (CPB) is a common technique in cardiac surgery but is associated with acute kidney injury (AKI), which carries considerable morbidity and mortality. In this review, we explore the range and definition of CPB-associated AKI and discuss the possible impact of different disease recognition methods on research outcomes. Furthermore, we introduce the specialized equipment and procedural intricacies associated with CPB surgeries. Based on recent research, we discuss the potential pathogenesis of AKI that may result from CPB, including compromised perfusion and oxygenation, inflammatory activation, oxidative stress, coagulopathy, hemolysis, and endothelial damage. Finally, we explore current interventions aimed at preventing and attenuating renal impairment related to CPB, and presenting these measures from three perspectives: (1) avoiding CPB to eliminate the fundamental impact on renal function; (2) optimizing CPB by adjusting equipment parameters, optimizing surgical procedures, or using improved materials to mitigate kidney damage; (3) employing pharmacological or interventional measures targeting pathogenic factors.

Hemolysis and cardiopulmonary bypass: meta-analysis and systematic review of contributing factors. J Cardiothorac Surg 2023; 18:291. [PMID: 37833747 PMCID: PMC10571250 DOI: 10.1186/s13019-023-02406-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2023] [Accepted: 09/30/2023] [Indexed: 10/15/2023] Open
Abstract
BACKGROUND The use of cardiopulmonary bypass (CPB) is almost inevitable in cardiac surgery. However, it can cause complications, including hemolysis. Until now, there have not been any standards for reducing hemolysis from CPB. Therefore, this systematic review was conducted to determine the factors that increase or reduce hemolysis in the use of CPB. METHODS Keywords Earches (cardiac surgery AND cardiopulmonary bypass AND hemolysis) were done on PubMed databases and Cochrane CENTRAL from 1990-2021 for published randomized controlled trials (RCTs) that studied interventions on CPB, in cardiac surgery patients, and measured hemolysis as one of the outcomes. Studies involving patients with preoperative hematological disorders, prosthetic valves, preoperative use of intra-aortic balloon pumps and extracorporeal circulation, emergency and minimally invasive surgery are excluded RESULTS: The search yielded 64 studies that met the inclusion criteria, which involved a total of 3,434 patients. The most common surgery was coronary revascularization (75%). Out of 64 studies, 33 divided into 7 analyses. Remaining 31 studies were synthesized qualitatively. Significant decreases were found in centrifugal vs roller pumps for PFHb (p = 0.0006) and Hp (p < 0.0001) outcomes, separated vs combined suctioned blood (p = 0.003), CPB alternatives vs conventional CPB (p < 0.0001), and mini extracorporeal circulation (MiniECC) vs conventional CPB for LDH (p = 0.0008). Significant increases were found in pulsatility (p = 0.03) and vacuum-assisted venous drainage (VAVD) vs gravity-assisted venous drainage (GAVD) (p = 0.002). CONCLUSION The review shows that hemolysis could be caused by several factors and efforts have been made to reduce it, combining significant efforts could be beneficial. However, this review has limitations, such as heterogeneity due to no standards available for conducting CPB. Therefore, further research with standardized guidelines for CPB is needed to yield more comparable studies. Meta-analyses with more specific parameters should be done to minimize heterogeneity.

Abstract
Objective To provide a brief review of the development of cardiopulmonary bypass. Methods A review of the literature on the development of extracorporeal circulation
techniques, their essential role in cardiovascular surgery, and the
complications associated with their use, including hemolysis and
inflammation. Results The advancement of extracorporeal circulation techniques has played an
essential role in minimizing the complications of cardiopulmonary bypass,
which can range from various degrees of tissue injury to multiple organ
dysfunction syndrome. Investigators have long researched the ways in which
cardiopulmonary bypass may insult the human body. Potential solutions arose
and laid the groundwork for development of safer postoperative care
strategies. Conclusion Steady progress has been made in cardiopulmonary bypass in the decades since
it was first conceived of by Gibbon. Despite the constant evolution of
cardiopulmonary bypass techniques and attempts to minimize their
complications, it is still essential that clinicians respect the
particularities of each patient's physiological function.

Abstract
Objectives: There is some controversy as to whether there is a benefit from the use of a centrifugal pump compared with a roller pump during cardiopulmonary bypass to facilitate cardiac surgery. We compared the two pumps, with the primary aim of determining any difference in the effects on inflammation after pulmonary endarterectomy surgery which required prolonged cardiopulmonary bypass and deep hypothermic circulatory arrest. Methods: Between September 2010 and July 2013, 58 elective patients undergoing pulmonary endarterectomy were included in this prospective, randomised, controlled study; 30 patients were randomly allocated to the control group, which used a roller pump, and 28 patients to the treatment group, which used a centrifugal pump. Interleukin-6, procalcitonin, C-reactive protein, thromboelastographic parameters, P-selectin, international normalised ratio, activated prothrombin time, free haemoglobin, haematocrit, red blood cell count, white blood cell count, platelet count and protein S100β were recorded during and after the procedure. We also recorded the length of intensive care unit stay, blood loss and transfusion, neurological outcomes and respiratory and renal failure. Results: There was a significant difference in the primary outcome measure: Interleukin-6 was significantly higher in the roller pump group (587±38 ng·l-1 vs. 327±37 ng·l-1; p<0.001) 24 hours after surgery, which we interpreted as an increased inflammatory response. This was confirmed by a significant rise in the procalcitonin level in the roller pump group 48 hours following surgery (0.79 (0.08-25.25) ng·ml-1 vs. 0.36 (0.02-5.83) ng·ml-1; p<0.05). There were, however, no significant differences in clinical outcome data. Conclusions: We have shown that the use of a centrifugal pump during prolonged cardiopulmonary bypass and deep hypothermic circulatory arrest is associated with a reduced inflammatory response compared to the standard roller pump. Larger multi-centre trials in this area of practice are required.

Abstract
Background: In this study, we assessed clinical results by using a minimal extracorporeal circuit (MECC) and compared it to a conventional cardiopulmonary bypass (CPB) system in patients undergoing coronary artery bypass grafting (CABG) procedures. Methods and Materials: From August to October 2006, forty consecutive patients undergoing isolated CABG procedures were randomly assigned to either a miniaturized closed circuit CPB with the Maquet-Cardiopulmonary MECC system (Group M, n=20) or to a conventional CPB system (Group C, n=20). Clinical outcomes were observed before, during and after the operation. Besides evaluating the perioperative clinical data, serial blood venous samples were obtained after induction, 30 minutes after CPB initiation, 2h, 6h, 12h, and 24h post-CPB. The focus of our study was on myocardial damage (cTnI), neutrophil and platelet counts, activated partial thromboplastin time (aPTT) and free hemoglobin. Results: Both the transfusion of packed red blood cells and fresh frozen plasma were significantly lower in Group M compared to Group C ( p<0.05). The levels of cTnI were lower in Group M at 2h, 6h and 12h post-CPB than in Group C ( p<0.01). The values of aPTT in Group M recovered to normal levels after surgery, but were prolonged in Group C at early post-CPB and were statistically longer than Group M at 2h, 6h, and 12h post-CPB ( p<0.05). The concentrations of free hemoglobin in Group C were higher than in Group M during and post-CPB, and there was a statistical difference at 2h post-CPB ( p<0.05). Conclusion: In conclusion, the MECC system is a safe alternative for patients who undertake extracorporeal circulation (ECC) for CABG surgery. Lower transfusion requirements and less damage to red cells may further promote the use of MECC systems, especially in higher risk patients.

Abstract
During the last decade, minimized extracorporeal circulation (MECC) systems have shown beneficial effects to the patients over the conventional cardiopulmonary bypass (CECC) circuits. This is a prospective randomized study of 99 patients who underwent coronary artery bypass grafting (CABG) surgery, evaluating the postoperative haematological effects of these systems. Less haemodilution (p=0.001) and markedly less haemolysis (p<0.001), as well as better preservation of the coagulation system integrity (p=0.01), favouring the MECC group, was found. As a clinical result, less bank blood requirements were noted and a quicker recovery, as far as mechanical ventilation support and ICU stay are concerned, was evident with the use of MECC systems. As a conclusion, minimized extracorporeal circulation systems may attenuate the adverse effects of conventional circuits on the haematological profile of patients undergoing CABG surgery.

Abstract
A feasibility study is performed to quantify sheep platelets (PLTs) and to identify the relationship between PLT count and hemolysis as a consequence of mechanical stress. Six adult, healthy Dorset sheep have been used for in vitro blood sampling test procedures in a hemoresistometer device (HRM). In each experiment, blood of the same animal was exposed to six different shear rates. Free hemoglobin levels and PLT count for each shear rate were detected. In all animals (A-F), hemolysis increased significantly between the shear rates of 2325 and 3100/s (P < 0.05) and the mean PLT count dropped immediately (contact, low shear) 40% in the beginning, between the shear rates of 0 and 775/s (P < 0.05). PLT count increased slightly as soon as hemolysis started. At higher shear rates, hemolysis increased and PLTs reduced further. Precise counting of PLTs indicates that PLTs are consumed dramatically at very low shear (by contact) and further by applied mechanical stress when hemolysis is obvious. A repetition of these tests with human blood could indicate species differences.

Abstract
The standard heart-lung machine is deemed a major trigger of systemic inflammatory reactions, potentially inducing organ failure. The strict reduction of blood-artificial surface and blood-air contact might represent meaningful improvements of the extracorporeal technology with respect to organ preservation. In this study, we assessed perioperative myocardial damage by using a novel minimal extracorporeal circuit (MECC) and a conventional cardiopulmonary bypass (CPB) system. Sixty patients scheduled for coronary artery bypass surgery were randomly assigned to either the MECC or the standard CPB system. Myocardial markers were determined by specific immunoassays 6, 12, and 24 hours after CPB initiation. Results were corrected for hemodilution.Demographics, hemodynamics, the number of anastomoses, CPB, and cross-clamp time were comparable between the groups. MECC patients demonstrated significantly lower levels of Troponin T (ng/ml) at 6, 12, and 24 hours (0.07 +/- 0.01 vs. 0.16 +/- 0.04, p < 0.005; 0.12 +/- 0.03 vs. 0.28 +/- 0.08, p < 0.008; 0.21 +/- 0.05 vs. 0.35 +/- 0.09, p < 0.03, respectively) and creatine kinase-MB (U/l) at 6 and 12 hours (22.5 +/- 1.5 vs. 40.6 +/- 3.3, p < 0.0001; 23.3 +/- 3.4 vs. 40.8 +/- 8.0, p < 0.001, respectively). Creatine kinase-MB at 24 hours tended to lower values in the MECC group but did not quite reach statistical significance. The MECC system may not only provide a less invasive solution to meet the requirements during cardiac surgery but also a more organ-preserving alternative to standard CPB.

Circulating endothelial cells demonstrate an attenuation of endothelial damage by minimizing the extracorporeal circulation. J Thorac Cardiovasc Surg 2006; 132:291-6.

Abstract
OBJECTIVE Detachment of endothelial cells may represent serious injury of the endothelium after cardiopulmonary bypass. We investigated whether the extent of endothelial injury is related to the type of cardiopulmonary bypass system used (conventional or minimized) and determined circulating endothelial cells as well as von Willebrand factor and soluble thrombomodulin. METHODS Twenty patients scheduled for elective coronary bypass grafting were randomly assigned to either the minimal extracorporeal circulation system or the standard cardiopulmonary bypass. Ten healthy volunteers served as controls. Circulating endothelial cells per milliliter of full blood were perioperatively determined by immunomagnetic cell separation technique. Endothelial plasma markers were measured by enzyme-linked immunosorbent assay. RESULTS Preoperative circulating endothelial cell numbers did not differ between the experimental groups, but were significantly higher than in the healthy controls (18.6 +/- 5.6 vs 7.2 +/- 3.8, P < .001). At 6 hours, circulating endothelial cell numbers increased significantly compared with baseline in both experimental groups and peaked at 12 hours after cardiopulmonary bypass initiation, each time with significantly lower values in the minimal extracorporeal circulation group (6 hours: 44.0 +/- 9.9 vs 29.6 +/- 9.8, P = .007; 12 hours: 48.1 +/- 6.8 vs 31.8 +/- 7.1, P < .001). Likewise, von Willebrand factor and soluble thrombomodulin postoperatively increased in both groups with a tendency toward lower levels in the minimal extracorporeal circulation group. Although circulating endothelial cells gradually declined, continually with lower numbers in the minimal extracorporeal circulation group, the endothelial plasma markers remained elevated during observation time. CONCLUSIONS Circulating endothelial cells represent a novel marker of the intrinsic endothelial damage caused by cardiopulmonary bypass. Its analysis facilitates the evaluation of cardiopulmonary bypass modifications as the minimal extracorporeal circulation system could be proven to be less injurious to endothelium and myocardium.

Abstract
Suppression of prostacyclin (PGI2) biosynthesis may explain the increased incidence of myocardial infarction and stroke which has been observed in placebo controlled trials of cyclooxygenase (COX)-2 inhibitors. Herein, we examine if COX-2-derived PGI2 might condition the response of the vasculature to sustained physiologic stress in experimental models that retain endothelial integrity. Deletion of the PGI2 receptor (IP) or suppression of PGI2 with the selective COX-2 inhibitor, nimesulide, both augment intimal hyperplasia while preserving luminal geometry in mouse models of transplant arteriosclerosis or flow-induced vascular remodeling. Moreover, nimesulide or IP deletion augments the reduction in blood flow caused by common carotid artery ligation in wild-type mice. Generation of both thromboxane (Tx)A2 and the isoprostane, 8, 12 -iso iPF(2alpha)-VI, are increased in the setting of flow reduction and the latter increases further on administration of nimesulide. Deletion of the TxA2 receptor (TP) reduces the hyperplastic response to nimesulide and carotid ligation, despite further augmentation of TP ligand production. Suppression of COX-2-derived PGI2 or deletion of IP profoundly influences the architectural response of the vasculature to hemodynamic stress. Mechanism based vascular remodeling may interact with a predisposition to hypertension and atherosclerosis in contributing to the gradual transformation of cardiovascular risk during extended periods of treatment with selective inhibitors of COX-2.

Abstract
PURPOSE Blood pumps are routinely used for circulatory and pulmonary support. However, blood trauma and pump failure remain severe drawbacks of currently available pump models. This study evaluated the first clinical application of a new, totally bearingless centrifugal blood pump (CentriMag). MATERIAL AND METHODS A centrifugal pump consisting of an electromagnetic suspended impeller was used as a blood pump during beating-heart coronary artery bypass grafting in 11 patients (mean weight, 77.4 kg). Heparin in a bolus of 150 IU/kg body weight was administered, and activated clotting time was maintained at approximately 180 to 250 seconds during extracorporeal circulation. Pump-induced blood trauma was evaluated by measurement of plasma free hemoglobin (PFH), lactate dehydrogenase (LDH), hematocrit, total bilirubin, and platelet levels. RESULTS Mean pump flow was 3.3 +/- 0.62 L/min, and mean pressure gradient through the oxygenator was 69 +/- 4 mm Hg. No pump dysfunction occurred during a mean application time of 105 +/- 26 minutes. Inspection of the pump housings showed no internal thrombus formation despite low-dose heparinization. Only slight hemolysis was observed with a mean PFH level of 1.96 micromol/L; LDH, 460 U/L; hematocrit, 33%; total bilirubin, 25 micromol/L; and platelets, 191 x 10(3)/microL. CONCLUSIONS The bearingless CentriMag blood pump is a safe and reliable new device that produces only minimal hemolysis. It seems to be suited for long-term evaluation as a blood pump for extracorporeal membrane oxygenation or as ventricular assist device.
