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.

Anticoagulation Monitoring During ECMO Support: Monitor or Flip a Coin?

This editorial reviews the complexities of anticoagulation monitoring during extracorporeal membrane oxygenation (ECMO), emphasizing the balance between preventing thromboembolic events and minimizing hemorrhagic risks. Current tools like ACT, aPTT, and anti-factor Xa assays are evaluated for their efficacy and limitations. While aPTT remains widely used, anti-factor Xa is emerging as a promising alternative. The authors call for more research and advanced monitoring strategies to improve clinical outcomes.

Novel Risk Scoring Model to Predict the Implementation of Veno-Arterial Extracorporeal Membrane Oxygenation in Patients With Acute Myocarditis

This study introduces the Korean Acute Myocarditis (KAM) score, a predictive model for assessing the likelihood of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) use in acute myocarditis. Analyzing data from 841 patients across seven Korean hospitals, eight clinical parameters were identified as predictors, including cardiac arrest and left ventricular ejection fraction <40%. The KAM score demonstrated excellent discriminant ability, supporting its potential to guide timely interventions and improve patient outcomes.

The Effects of Blood Cell Salvage on Transfusion Requirements After Decannulation from Veno-Venous Extracorporeal Membrane Oxygenation: An Emulated Trial Analysis

This study investigates the impact of blood cell salvage (BCS) during veno-venous extracorporeal membrane oxygenation (VV-ECMO) decannulation on transfusion needs. Using an emulated trial with 841 patients, the results showed BCS reduced transfusions of packed red blood cells (PRBC) and increased hemoglobin levels without affecting inflammatory or coagulation markers. These findings suggest BCS is an effective strategy for minimizing transfusion-related complications in VV-ECMO decannulation.

Anticoagulation Management for Veno-Venous ECMO in COVID-19 Patients: Argatroban as Rescue Therapy in Heparin-Associated Thrombocytopenia

This study examines the use of argatroban as an alternative to unfractionated heparin (UFH) for anticoagulation during veno-venous ECMO in COVID-19 patients with heparin-associated thrombocytopenia (HIT). Data from 40 patients revealed a lower incidence of bleeding with argatroban compared to UFH, particularly at tracheal stoma sites. Platelet counts showed better preservation with argatroban, despite comparable efficacy in preventing thrombotic events. Argatroban offers a safer alternative for HIT cases in ECMO.

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.

Intra-Aortic Balloon Pump After VA-ECMO Reduces Mortality in Cardiogenic Shock: Analysis from the Chinese Extracorporeal Life Support Registry

This multicenter study analyzed 5,492 patients with cardiogenic shock (CS) treated with venoarterial extracorporeal membrane oxygenation (VA-ECMO). Among them, 15.1% received intra-aortic balloon pump (IABP) for left ventricle unloading after VA-ECMO. The IABP group showed reduced in-hospital mortality (48.0% vs. 52.5%) and improved survival on VA-ECMO. However, increased risks of mechanical, bleeding, renal, and pulmonary complications were observed. Findings suggest IABP may enhance outcomes in CS patients on VA-ECMO but warrant further validation in randomized trials.

Bivalirudin ECMO

Prospective Randomized Pilot Study Comparing Bivalirudin Versus Heparin in Pediatric ECMO

This pilot randomized controlled trial compared bivalirudin and unfractionated heparin for anticoagulation in 30 pediatric ECMO patients. No difference was found in time at goal anticoagulation, the primary endpoint. However, bivalirudin was associated with higher thrombotic complications (37.5% vs. 0%; p=0.02) but required fewer RBC transfusions (median 6.3 vs. 12.2 mL/kg/day; p=0.02). The study demonstrates feasibility for larger trials to evaluate the safety and efficacy of bivalirudin in pediatric ECMO.

“Awake” Cannulation of Patients for Venovenous Extracorporeal Membrane Oxygenation: An Analysis of the Extracorporeal Life Support Organization Registry

This study analyzed the outcomes of “awake” cannulation, where patients remain breathing spontaneously during venovenous ECMO cannulation, using data from over 28,000 patients. Only 2.8% underwent awake cannulation, which was associated with similar survival rates to mechanical ventilation cannulation after propensity score matching. Awake cannulation, increasingly utilized over time, shows potential for reducing ventilator-related lung injury but requires further research to identify optimal patient cohorts.

Wavelet and Time-Based Cerebral Autoregulation Analysis Using Diffuse Correlation Spectroscopy on Adults Undergoing Extracorporeal Membrane Oxygenation Therapy

This study examines cerebral autoregulation (CA) in adult patients on extracorporeal membrane oxygenation (ECMO) therapy using diffuse correlation spectroscopy (DCS), a noninvasive approach to monitoring cerebral blood flow. Neurological injuries, common in ECMO patients due to underlying conditions or the therapy itself, can impair CA, potentially worsening brain damage. Using wavelet coherence analysis (WCA), researchers found that DCS-based markers identified significant CA differences in ECMO patients with brain injuries versus those without, highlighting the potential of DCS as a monitoring tool for this population.
