Link Between Cerebral Over-perfusion and Postoperative Delirium: Insights for Cardiac Surgery Care
The study, conducted by Marcus Thudium et al. and published in the Journal of Clinical Medicine, examines the connection between cerebral over-perfusion, cortical metabolism, and postoperative delirium (POD) in cardiac surgery patients. While decreased cerebral oxygen saturation (rSO2) has been associated with POD, interventions aimed at optimizing rSO2 have produced inconclusive results. The researchers conducted…

Optimizing Artificial Lungs: How Geometry Can Reduce Blood Clot Risks and Enhance Efficiency
A recent study by Angela Lai and colleagues, published in Bioengineering & Translational Medicine, explores the impact of geometric design in the fiber bundles of artificial lungs on blood clot formation. These hollow fiber bundles serve as the functional core of artificial lungs, enabling the exchange of oxygen and carbon dioxide. However, they are also…

Limitations in Gauging the Effects of Allocation Policy Changes on Liver Transplant
The Study analyzes the economic impact of changes in the United Network for Organ Sharing (UNOS) liver allocation policies. The researchers focus on how these policy shifts influence transplant costs, patient access, and overall transplant activity across different regions in the U.S. They highlight disparities caused by the new model, which redistributes livers to sicker…

Mapping the Global Scientific Progress on Minimal Invasive Extracorporeal Circulation: Key Trends, Collaborations, and Future Directions
The article “Minimal Invasive Extracorporeal Circulation: A Bibliometric Network Analysis of the Global Scientific Output” by Jacopo D’Andria Ursoleo et al., published in Perfusion, provides an in-depth bibliometric analysis of research on Minimal Invasive Extracorporeal Circulation (MiECC). MiECC has emerged as a potentially more “physiologic” alternative to conventional extracorporeal circulation used in cardiac surgery. Despite…

Transforming Heart Recovery in Circulatory Death Donors
Thoraco-abdominal normothermic regional perfusion (TA-NRP), supported by Extra Corporeal Membrane Oxygenation (ECMO) devices, is emerging as a groundbreaking strategy for heart recovery in donors declared dead by circulatory criteria (DCDD). In an article published in Transplant International (by Frontiers), Mario Royo-Villanova et al. detail the potential of this approach, which restores cardiac activity by re-establishing…

How Bypass Time Relative to Body Size Predicts Postoperative Complications in Cardiac Surgery
A recent study conducted by Florian Falter et al., published in Interdisciplinary CardioVascular and Thoracic Surgery, explored the impact of cardiopulmonary bypass (CPB) time indexed to body surface area (bypass index) on postoperative outcomes in cardiac surgery patients. The study focuses on the increased postoperative risks associated with prolonged CPB times, which is particularly relevant…

Impact of ECMO and CRRT Circuits on Ketamine and Dexmedetomidine Levels: Adjusting Sedative Dosing in ECLS-Supported Patients
The study by Andrew Chevalier and colleagues, published in the Journal of Extracorporeal Technology, investigates how extracorporeal life support (ECLS) circuits, specifically ECMO (extracorporeal membrane oxygenation) and CRRT (continuous renal replacement therapy), affect the pharmacokinetics of sedatives ketamine and dexmedetomidine. These medications are commonly administered to patients on ECLS for pain and sedation management. ECLS…

Practices and Standards in Pre-assembling and Storing ECMO Systems
The article “Clinical Practice of Preassembling and Storing of Extracorporeal Membrane Oxygenation Systems” by Patrick Winnersbach et al., published in ASAIO, explores current practices related to preassembling and storing ECMO systems in German medical centers. According to the Extracorporeal Life Support Organization (ELSO) guidelines, preassembled, primed ECMO systems can be safely stored for up to…

Expanding Kidney Transplants: The Benefits of a 3-Hour Wait Policy for Donor Time to Death.
The study “Donor Time to Death and Kidney Transplant Outcomes in the Setting of a 3-Hour Minimum Wait Policy” conducted by Samuel J. Tingle and colleagues, published in JAMA Network Open, explores the potential benefits of extending the minimum wait time for organ donation after circulatory death (DCD) to address the growing demand for kidney transplants. Current international…

White Blood Cell Counts as a Predictor of Heparin Requirements During ECMO in Lung Transplantation
A recent study by Koichi Kashiwa et al., published in the Journal of Extracorporeal Technology, investigated the relationship between inflammatory parameters, mainly white blood cell (WBC) counts, and the need for increased dosages of unfractionated heparin (UFH) during veno-arterial extracorporeal membrane oxygenation (V-A ECMO) in lung transplantation. The retrospective observational study included 27 patients who…

Key Risk Factors for Vasoplegic Syndrome in Coronary Artery Bypass Surgery: Insights for Improved Prevention and Outcomes
A recent study by Constantin L Palm et al., published in Frontiers in Cardiovascular Medicine, investigated the risk factors for developing vasoplegic syndrome (VS) in patients undergoing coronary artery bypass graft (CABG) surgery. The vasoplegic syndrome is a serious postoperative complication that involves significant drops in blood pressure (mean arterial pressure ≤60 mmHg) and requires…
