The Role of Continuous Monitoring of Venous Drainage Flow and Integrated Oxygen Extraction (ERiO2) via Bilateral Near-Infrared Spectroscopy in Cerebral Perfusion During Aortic Arch Surgery

The Role of Continuous Monitoring of Venous Drainage Flow and Integrated Oxygen Extraction (ERiO2) via Bilateral Near-Infrared Spectroscopy in Cerebral Perfusion During Aortic Arch Surgery

This study evaluates the role of continuous monitoring of venous drainage flow and oxygen extraction (ERiO2) using near-infrared spectroscopy (NIRS) in cerebral perfusion during aortic arch surgery. A retrospective review of 10 patients undergoing selective antegrade cerebral perfusion (SACP) found a strong correlation (r = 0.91, p < 0.01) between ERiO2 and NIRS-derived regional oxygen saturation (rSO2). The study suggests that integrated monitoring improves perfusion management and neurological outcomes.

Outcomes and Biochemical Parameters Following Cardiac Surgery: Effects of Transfusion of Residual Blood Using Centrifugation and Multiple-Pass Hemoconcentration

Outcomes and Biochemical Parameters Following Cardiac Surgery: Effects of Transfusion of Residual Blood Using Centrifugation and Multiple-Pass Hemoconcentration

This study compares centrifugation (CF) and multiple-pass hemoconcentration (MPH) for salvaging residual blood after cardiopulmonary bypass. A randomized trial with 61 patients found that MPH resulted in higher postoperative albumin, total protein, fibrinogen, and platelet levels compared to CF. While CF processed blood faster and cleared heparin more consistently, MPH was associated with lower allogeneic transfusion needs and reduced fluid retention. Overall, MPH demonstrated improved biochemical and clinical outcomes.

Efficacy and Safety of the Blood-Based Cardioplegia Solution Huaxi-1 in Cardiopulmonary Bypass Surgery: Protocol for a Multicentre Randomised Controlled Trial

This study evaluates the safety and efficacy of the Huaxi-1 blood-based cardioplegia solution compared to the widely used HTK solution in cardiopulmonary bypass surgery. A randomized, multicenter trial involving 160 adult patients across four hospitals in China will measure myocardial injury markers, cardiac function, and post-surgical recovery. The goal is to establish Huaxi-1’s viability as a standardized cardioplegia solution for improved myocardial protection.

The Influence of Cardiopulmonary Bypass Residual Volume Processing Technique on Blood Management in Cardiac Surgical Patients

The Influence of Cardiopulmonary Bypass Residual Volume Processing Technique on Blood Management in Cardiac Surgical Patients

This study examines different techniques for processing post-cardiopulmonary bypass (CPB) residual blood and their impact on intraoperative red blood cell (RBC) transfusions. Analyzing data from over 77,000 adult cardiac surgeries, the study found that using Hemobag (HB) resulted in the lowest transfusion risk, while not processing blood (NO) led to the highest. The findings highlight the importance of effective blood conservation strategies in cardiac surgery.

On-Pump FIBTEM-A5 Accurately Predicts the A5 Values After Protamine Administration

This study investigates whether on-pump FIBTEM-A5 values measured during cardiopulmonary bypass (CPB) accurately predict post-protamine administration values. Conducted at a single cardiac center, the retrospective analysis of 70 patients found a strong correlation (R² = 0.813) between the two measurements. Despite a statistically significant but clinically negligible difference, the findings support using on-pump FIBTEM-A5 to guide fibrinogen supplementation in cardiac surgery.

EBCP 2024 Guidelines

2024 EACTS/EACTAIC/EBCP Guidelines on Cardiopulmonary Bypass in Adult Cardiac Surgery

The 2024 EACTS/EACTAIC/EBCP guidelines provide updated, evidence-based recommendations for cardiopulmonary bypass (CPB) in adult cardiac surgery. They cover advancements in perfusion strategies, organ protection, monitoring techniques, and safety measures. Key updates include AI-driven perfusion, enhanced neuromonitoring, and refined protocols for blood management and CPB separation. These guidelines aim to standardize practices, improve outcomes, and ensure patient safety in modern cardiac surgery.

Neurodevelopmental Outcomes After Nitric Oxide During Cardiopulmonary Bypass for Open Heart Surgery: A Randomized Clinical Trial

This randomized clinical trial examined whether nitric oxide (NO) administered during cardiopulmonary bypass (CPB) improves neurodevelopmental and health-related quality of life (HRQOL) outcomes in infants undergoing open heart surgery. Conducted across six centers, the study followed 927 infants at 12 months post-surgery. Results showed no significant differences in neurodevelopment or HRQOL between the NO and standard CPB groups, suggesting NO does not enhance long-term neurological outcomes.

Platelet Inhibitor Withdrawal and Outcomes After Coronary Artery Surgery: An Individual Patient Data Meta-Analysis

Platelet Inhibitor Withdrawal and Outcomes After Coronary Artery Surgery: An Individual Patient Data Meta-Analysis

This study analyzes the impact of preoperative withdrawal of P2Y12 receptor inhibitors on bleeding and ischemic outcomes in coronary artery bypass grafting (CABG). Using individual patient data from 4,837 patients across seven observational studies, the meta-analysis finds that guideline-conforming withdrawal reduces severe bleeding (BARC-4) risk by 50% without increasing mortality or postoperative ischemic events. These findings support adherence to standardized preoperative withdrawal guidelines.

Failure to Oxygenate During Cardiopulmonary Bypass: Treatment Options and Intervention Algorithm

Failure to Oxygenate During Cardiopulmonary Bypass: Treatment Options and Intervention Algorithm

This study addresses the critical issue of oxygenator failure during cardiopulmonary bypass (CPB), a rare but high-risk event. It explores protocols and techniques for addressing oxygenator malfunction, including traditional oxygenator change-outs and alternative approaches like arterial and venous piggyback methods. The authors emphasize the need for institutional preparation, including written protocols and routine emergency drills, and propose a venous piggyback technique as a safer first-line response to improve patient outcomes.
