Cerebral Perfusion

Cerebral Overperfusion Despite Reduced Cortical Metabolism Is Associated with Postoperative Delirium in Cardiac Surgery Patients: A Prospective Observational Study

This study investigates the relationship between cerebral overperfusion and postoperative delirium (POD) in cardiac surgery patients. Despite reduced cortical metabolism, patients with POD exhibited increased cerebral blood flow, measured via transcranial Doppler. Low bispectral index (BIS) values indicated reduced metabolism, but no differences in autoregulation impairments were noted. The findings suggest a mismatch between cerebral blood flow and metabolism contributes to POD, independent of cerebral autoregulation.

Intraoperative Extracorporeal Support for Lung Transplant: A Systematic Review and Network Meta-Analysis

This systematic review and network meta-analysis investigates the comparative effectiveness of veno-arterial extracorporeal membrane oxygenation (V-A ECMO), cardiopulmonary bypass (CPB), and OffPump strategies for lung transplantation (LT). Based on 27 observational studies with 6113 patients, the study finds that OffPump approaches outperform both ECMO and CPB in all major outcomes, including reduced ICU stay, mechanical ventilation duration, and mortality. Among extracorporeal supports, V-A ECMO showed better performance than CPB. Factors such as age, gender, and BMI significantly influenced postoperative outcomes.

Removal of Cytokines During Cardiac Surgery (RECCAS): A Randomised Controlled Trial

This randomized controlled trial evaluates the efficacy of intraoperative haemoadsorption (HA) using CytoSorb® during cardiac surgery with cardiopulmonary bypass (CPB). The primary focus was on reducing interleukin-6 (IL-6) levels post-surgery. Despite a significant reduction in cytokine levels within the HA device during surgery, there was no difference in IL-6 levels between the treatment and control groups upon ICU admission or during the ICU stay. Some haemodynamic benefits, such as reduced fluid and fibrinogen requirements and shorter need for renal replacement therapy, were observed, though these did not translate into improved clinical outcomes like ICU length of stay or mortality rates. The study underscores the need for further large-scale trials to refine patient selection and HA application strategies.

Cold Platelets

Delayed Cold-Stored vs. Room Temperature Stored Platelet Transfusions in Bleeding Adult Cardiac Surgery Patients—A Randomized Multicentre Pilot Study (PLTS-1)

This study investigates the feasibility of using delayed cold-stored platelets (DCSP) compared to standard room-temperature platelets (RTP) in bleeding cardiac surgery patients. DCSP, stored initially at 22°C and then refrigerated, may address platelet supply challenges by extending shelf life and enhancing hemostatic activity. The multicentre pilot aims to assess recruitment, adherence, and product availability to inform a future definitive trial. The trial could improve transfusion logistics and patient outcomes.

Plasma CABG

Differences in Plasma Extracellular Vesicles of Different Origin in On-Pump Versus Off-Pump Cardiac Surgery

This study compares the immune responses of patients undergoing coronary artery bypass grafting (CABG) via on-pump and off-pump methods. On-pump CABG induced a more significant immune response, with notable increases in extracellular vesicles (EVs) derived from platelets, endothelial cells, and B-cells. Off-pump surgery was associated with milder changes in cytokine and EV profiles. Findings highlight EVs’ role in regulating postoperative inflammation and suggest a potential mechanism for immune modulation.

Off Pump CABG

The Value of Off-Pump Coronary Artery Bypass Grafting in Surgery for Combined Valvular and Coronary Heart Disease

This study explores the benefits of off-pump coronary artery bypass grafting (OPCABG) in surgeries combining valve and coronary interventions. Among 884 patients, the OPCABG group showed reduced incidences of postoperative atrial fibrillation (29.5% vs. 39.5%) and acute kidney injury (14.5% vs. 21.2%) compared to on-pump CABG. No differences in mortality or stroke rates were observed. The results suggest OPCABG is a safe and effective approach for improved short-term outcomes in complex cardiac surgeries.

Algorithm of High-Risk Massive Pulmonary Thromboembolism with Extracorporeal Membrane Oxygenation

Algorithm of High-Risk Massive Pulmonary Thromboembolism with Extracorporeal Membrane Oxygenation

This study evaluates the use of extracorporeal membrane oxygenation (ECMO) in treating high-risk massive pulmonary embolism (PE) in 27 patients from 2018 to 2023. ECMO was initiated pre-, intra-, or post-operatively in conjunction with surgical embolectomy or catheter-based thrombectomy. ECMO demonstrated significant benefits, including hemodynamic stabilization, reduced right ventricular overload, and improved survival (81.5%). Challenges included Harlequin syndrome and procedural complications. Findings support ECMO as a bridge to recovery, emphasizing the need for optimized patient selection and management strategies.

Sodium CPB

Relation Between Serum Sodium Trajectory and Survival in Septic Patients with Cardiopulmonary Bypass Surgery

This study examined the impact of serum sodium trajectory on 30-day mortality in septic patients after cardiopulmonary bypass (CPB) surgery using the MIMIC-IV database. Among 1,038 patients, serum sodium trajectories were classified into three groups, with higher levels linked to increased mortality. Elevated fluctuations, even within normal sodium ranges, were associated with adverse outcomes. These findings highlight the need for close monitoring and sodium management in critically ill patients undergoing CPB.

Five Pillars

Acute Right Ventricular Heart Failure, ECMO, RVAD, Hemodynamic Support, Five Pillars Framework

A conceptual representation of the “Five Pillars” framework for aRHF therapy. The image shows five pillars, each labeled with key aspects: Etiological Treatment, Hemodynamic Support, Ventilation, Fluid Optimization, and Mechanical Support. A heart is balanced on top of these pillars, symbolizing stability. The design is clean and professional, with subtle arrows indicating the interconnectedness of the pillars.

Hyperlactataemia Following Crystalloid Cardiopulmonary Bypass Priming in Paediatric Cardiac Surgery: Benign or Malignant?

This retrospective study examined paediatric patients undergoing cardiac surgery with crystalloid priming to evaluate outcomes related to postoperative hyperlactataemia. Among 186 patients, 53% experienced hyperlactataemia, which was associated with longer cardiopulmonary bypass and ICU stays but did not increase ventilation duration. Findings suggest transient hyperlactataemia may not indicate tissue hypoxaemia, but longer inotropic support and ICU stays necessitate careful management post-surgery.
