Effects of Albumin and Crystalloid Priming Strategies on Red Blood Cell Transfusions in On-pump Cardiac Surgery: A Network Meta-analysis

February 8, 2024 No Comments

This network meta-analysis evaluates the impact of albumin and crystalloid priming strategies on red blood cell transfusion requirements in on-pump cardiac surgery. The study reviewed 830 studies and included 10 in the final analysis. The findings suggest that crystalloid priming may significantly decrease total perioperative red blood cell transfusions compared to albumin. However, the difference in postoperative transfusions was not statistically significant. Both direct comparisons and network meta-analysis indicate that albumin priming results in higher transfusion rates, suggesting a reconsideration of its use in cardiac surgery for optimal blood management.

Association Between Lactic Acidosis and Multiple Organ Dysfunction Syndrome After Cardiopulmonary Bypass

February 6, 2024 No Comments

The study investigates the link between lactic acidosis and multiple organ dysfunction syndrome (MODS) post-cardiopulmonary bypass (CPB). A post hoc analysis on cardiac surgery patients shows a correlation between lactic acidosis and higher incidences of MODS, with lactic acidosis patients experiencing the worst outcomes. The research suggests the need for intensive monitoring of lactic acidosis post-CPB to mitigate risks and improve patient care.

Target Flow Deviations on the Cardiopulmonary Bypass Cause Postoperative Delirium in Cardiothoracic Surgery – A Retrospective Study Evaluating Temporal Fluctuations of Perfusion Data

February 5, 2024 No Comments

This study investigates the role of cardiopulmonary bypass (CPB) in postoperative delirium following cardiac surgery, employing algorithm-based data analysis on patient records from 2014 to 2019. It identifies not only demographic and comorbidity predictors but also highlights the significance of CPB parameters in delirium risk. Specifically, total blood volume and minimal blood flow rates during CPB were linked to delirium outcomes. The findings suggest that meticulous management of CPB parameters, especially flow rates and acid-base balance, could mitigate the risk of postoperative delirium, emphasizing the potential of precise CPB data processing in improving post-surgical care.

Development and Validation of a Machine Learning Method to Predict Intraoperative Red Blood Cell Transfusions in Cardiothoracic Surgery

February 4, 2024 No Comments

A novel machine learning (ML) method has been developed to predict red blood cell (RBC) transfusion requirements in cardiothoracic surgery, enhancing blood inventory management and preoperative hemorrhage risk assessment. Utilizing data from 2410 surgeries between May 2014 and June 2019, with an additional 437 cases for validation, this method employs a hybrid approach combining Gaussian Process regression and classification algorithms. The model accurately predicts both minor (0 to 3 units) and significant (4+ units) RBC transfusions, showing promise for integrating ML into surgical planning and patient care optimization.

Association between Intraoperative Blood Salvage and Coagulation Disorder after Cardiopulmonary Bypass

February 4, 2024 No Comments

This study assesses the relationship between intraoperative blood salvage and coagulation disorders following cardiopulmonary bypass (CPB), using conventional coagulation tests and thromboelastography (TEG). Enrolling 92 patients undergoing cardiovascular surgery with CPB, it explored coagulation function in scenarios with and without cell salvage blood transfusion. Despite 57.6% of patients receiving cell salvage, the occurrence of coagulation disorders post-CPB showed no significant difference between groups, indicating that intraoperative blood salvage does not significantly impact coagulation disorder risk as diagnosed by TEG or conventional tests.

Efficacy of Electroacupuncture on Myocardial Protection and Postoperative Rehabilitation in Patients Undergoing Cardiac Surgery with Cardiopulmonary Bypass: A Systematic Review and Meta-Analysis

January 26, 2024 No Comments

This study evaluated the efficacy of electroacupuncture (EA) in myocardial protection and postoperative rehabilitation in patients undergoing cardiac surgery with cardiopulmonary bypass, using data from fourteen randomized controlled trials involving 836 patients. The results suggest that EA may reduce myocardial ischaemia-reperfusion injury and enhance postoperative recovery, with no reported adverse reactions, although the findings are based on evidence of mostly low or moderate quality, indicating a need for more high-quality, large-scale studies.

The Anti-Apoptotic Effect of Ranolazine on Cerebral Protection during Cardiopulmonary Bypass and Carotid Artery Surgery

January 25, 2024 No Comments

This study investigated the neuroprotective effects of ranolazine (Rn) in a rat model of cerebral ischemia induced by carotid artery clamping. Results showed that Rn-treated groups had significant changes in various biochemical markers, indicating an antiapoptotic effect of Rn in brain ischemia-reperfusion, suggesting its potential usability in cardiac surgeries and carotid artery interventions.

Surgical Management and Outcomes of Coronary Artery Involvement Secondary to Acute Type A Aortic Dissection: A Retrospective Cohort Study

January 23, 2024 No Comments

In a study of patients with acute type A aortic dissection (ATAAD) undergoing total arch replacement (TAR) and frozen elephant trunk (FET) implantation, it was found that those with coronary artery involvement (CAI) experienced more complicated surgeries, longer hospital stays, and higher rates of in-hospital morbidity and mortality compared to those without CAI. Although coronary artery malperfusion (CAM) due to CAI was an independent risk factor for in-hospital mortality, short-term survival post-discharge was similar between patients with and without CAI.

Finding a Common Definition of Heparin Resistance in Adult Cardiac Surgery: Communication from the ISTH SSC Subcommittee on Perioperative and Critical Care Thrombosis and Hemostasis

January 21, 2024 No Comments

Ensuring sufficient anticoagulation in cardiac surgery and cardiopulmonary bypass is crucial for preventing adverse outcomes. This review evaluates various definitions of heparin resistance in this context, proposing a standardized definition based on the inability to achieve an activated clotting time target of 480 or more after a dose of 500 U/kg of heparin.

Risk Factors and Short-Term Outcomes of Postoperative Pulmonary Complications in Elderly Patients After Cardiopulmonary Bypass

January 11, 2024 No Comments

This study on elderly patients undergoing cardiopulmonary bypass (CPB) found a high incidence (56.82%) of postoperative pulmonary complications (PPCs), identifying low serum albumin levels, specific types of surgery, prolonged CPB, blood transfusion, and pre-extubation intra-aortic balloon pump use as significant risk factors. These PPCs led to longer mechanical ventilation, extended hospital and ICU stays, increased mortality, and higher tracheotomy rates, highlighting the importance of recognizing these risk factors for better perioperative prevention in elderly CPB patients.
