Centrifugation versus filtration-based cell salvage: impact on perioperative bleeding in cardiac surgery-the COLTRANE randomised clinical trial - study protocol.

Introduction: Cardiac surgery remains a high-risk procedure for bleeding despite advances in patient blood management. Conventional centrifugation-based autotransfusion devices primarily recover red blood cells, losing platelets and coagulation factors. The SAME autotransfusion device (i-SEP, Nantes, France) introduces an innovative filtration-based approach, recovering erythrocytes, leucocytes and platelets to enhance perioperative haemostasis.

Feasibility of a Systematic Same-Day Discharge Approach After Elective Mitral Transcatheter Edge-to-Edge Repair.

•Same-day discharge after elective mitral-transcatheter edge-to-edge repair (M-TEER) can be proposed in a selected patient population.•Same-day discharge after elective M-TEER seems safe in a selected patient population.•Around one patient out of 5 may be eligible for a same-day discharge management after M-TEER.

Maintaining ventilation with very low tidal volume and positive-end expiratory pressure versus no ventilation during cardiopulmonary bypass for cardiac surgery in adults: a randomized clinical trial.

Purpose: Cardiopulmonary bypass (CPB) during cardiac surgery mechanically circulates and oxygenates the blood, bypassing the heart and lungs. Despite limited evidence, maintaining mechanical ventilation (MV) during CPB is recommended, as ventilator strategies during surgery may reduce the occurrence of postoperative infections. We aimed to determine whether maintaining MV for cardiac surgery would decrease postoperative infections compared with stopping MV during CPB.

Prone positioning during veno-venous extracorporeal membrane oxygenation: a systematic review and meta-analysis.

Purpose: The evidence supporting the benefit on clinical outcomes of prone positioning during veno-venous extracorporeal membrane oxygenation (V-V ECMO) for acute hypoxemic respiratory failure remains inconclusive. We aimed to assess the association of prone positioning, compared to no prone positioning, with 28-day mortality and other clinical outcomes in different patient subgroups.

Methods: A systematic review and meta-analysis of randomized and non-randomized controlled trials (RCTs) using a random-effects model was conducted.

Donation after circulatory death heart transplantation: The French perspective.

Heart transplantation is the gold standard treatment for patients with advanced heart failure in the absence of contraindications. In recent years, the shortage of heart donors has led to a resurgence in the use of hearts from donation after circulatory death (DCD) donors after withdrawal of life-sustaining treatment. In these donors, death is determined by the cessation of spontaneous circulation and respiration for≥5minutes and is confirmed by neurological criteria.

Characteristics and outcomes of ECMO cannula-related infections: a European multicenter retrospective study.

Objective: Only few data regarding epidemiology and management of ECMO cannula-related infections (ECMO-CRIs) exist. The aim of our study was to describe their epidemiology and prognosis, and to evaluate factors associated with outcome.

Methods: We performed a multicenter retrospective study in 12 European ICUs, including patients with ECMO-CRI, defined as a clinical suspicion plus a positive bacterial sample of ECMO-cannulation site.

Which antimicrobial treatment for patients with bloodstream infection during ECMO support?

Ojective: We aim to describe a large, multicenter cohort of patients with bloodstream infection (BSI) acquired during extracorporeal membrane oxygenation (ECMO) support.

Methods: We conducted a retrospective observational study in 12 Europeans ICUs. Only patients who developed a BSI of unknown source during ECMO support were included in the present analysis.

Elevated cell-free hemoglobin: A novel early biomarker following traumatic injury.

Background: Cell-free hemoglobin (CFH) and free heme are potent mediators of endotheliopathy and organ injury in sepsis, but their roles in other hemolytic pathologies are not well-defined. A prime example is trauma where early hemolysis may initiate damage and predict outcome. Here, we investigated the presence of plasma CFH, heme, and their major scavengers after traumatic injury.

Effectiveness of water system chemical disinfection against Pseudomonas aeruginosa infections, despite a not-so-obvious connection.

Background: Pseudomonas aeruginosa is a well-recognized opportunistic pathogen frequently responsible for hospital-acquired infections. Acquisition routes of P aeruginosa are both endogenous and exogenous, including transmission from a portion of the hospital water system.

Methods: The impact of disinfection procedures of the water system and description routes of P aeruginosa transmission in a surgical intensive care unit over a 2-year period were investigated.

Oxygenation management during veno-arterial ECMO support for cardiogenic shock: a multicentric retrospective cohort study.

Backgound: Hyperoxemia is common and associated with poor outcome during veno-arterial extracorporeal membrane oxygenation (VA ECMO) support for cardiogenic shock. However, little is known about practical daily management of oxygenation. Then, we aim to describe sweep gas oxygen fraction (FO), postoxygenator oxygen partial pressure (PO), inspired oxygen fraction (FO), and right radial arterial oxygen partial pressure (PO) between day 1 and day 7 of peripheral VA ECMO support.

Prevention of post-operative delirium using an overnight infusion of dexmedetomidine in patients undergoing cardiac surgery: a pragmatic, randomized, double-blind, placebo-controlled trial.

Background: After cardiac surgery, post-operative delirium (PoD) is acknowledged to have a significant negative impact on patient outcome. To date, there is no valuable and specific treatment for PoD. Critically ill patients often suffer from poor sleep condition.

Antithrombin Levels and Heparin Responsiveness during Venoarterial Extracorporeal Membrane Oxygenation: A Prospective Single-center Cohort Study.

Background: Unfractionated heparin, administered during venoarterial extracorporeal membrane oxygenation to prevent thromboembolic events, largely depends on plasma antithrombin for its antithrombotic effects. Decreased heparin responsiveness seems frequent on extracorporeal membrane oxygenation; however, its association with acquired antithrombin deficiency is poorly understood. The objective of this study was to describe longitudinal changes in plasma antithrombin levels during extracorporeal membrane oxygenation support and evaluate the association between antithrombin levels and heparin responsiveness.

Porcine bioprostheses for surgical aortic valve replacement: very long-term performance of a third-generation device.

Aims: We aimed at investigating the long-term durability of the Epic bioprosthesis for surgical aortic valve replacement (SAVR) in a single-centre series of 888 implantations (2001-2018), expanding previous evaluations with shorter follow-up.

Methods: We retrieved prospectively collected in-hospital data and performed a systematic follow-up focusing on valve-related events (SVD, structural valve deterioration; PPM, patient-prosthesis mismatch; reoperation) (competing risks, CIF and Kaplan--Meier methods). We distinguished between SVD (permanent changes in valve function due to evolutive structural deterioration, ≥10 mmHg average gradient vs.

Combined Platelet and Red Blood Cell Recovery during On-pump Cardiac Surgery Using same™ by i-SEP Autotransfusion Device: A First-in-human Noncomparative Study (i-TRANSEP Study).

Background: Centrifugation-based autotransfusion devices only salvage red blood cells while platelets are removed. The same™ device (Smart Autotransfusion for ME; i-SEP, France) is an innovative filtration-based autotransfusion device able to salvage both red blood cells and platelets. The authors tested the hypothesis that this new device could allow a red blood cell recovery exceeding 80% with a posttreatment hematocrit exceeding 40%, and would remove more than 90% of heparin and 75% of free hemoglobin.

Veno-arterial extracorporeal membrane oxygenation for circulatory failure in COVID-19 patients: insights from the ECMOSARS registry.

Objectives: The clinical profile and outcomes of patients with Coronavirus Disease 2019 (COVID-19) who require veno-arterial extracorporeal membrane oxygenation (VA-ECMO) or veno-arterial-venous extracorporeal membrane oxygenation (VAV-ECMO) are poorly understood. We aimed to describe the characteristics and outcomes of these patients and to identify predictors of both favourable and unfavourable outcomes.

Methods: ECMOSARS is a multicentre, prospective, nationwide French registry enrolling patients who require veno-venous extracorporeal membrane oxygenation (ECMO)/VA-ECMO in the context of COVID-19 infection (652 patients at 41 centres).

Association of Arterial Blood pH at Cannulation With 1 Year Survival Among Veno-Arterial Extracorporeal Membrane Oxygenation Recipients: The Three Seven Rule.

We aimed to describe the clinical outcomes of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) therapy in our institution considering clinical context and pH at cannulation. All patients treated by VA-ECMO during the 2005-2020 period with 1 year complete follow-up were included. Our cohort was divided in three groups according to the pH level at cannulation: pH <7 (group 1), pH 7-7.
