Extracorporeal Circulation During On-Pump Cardiac Surgery: An Evaluation of The Energy Equivalent Pressure (EEP) Index Based on Waveforms Decomposition in Harmonics
It is thus demonstrated that the surplus energy provided by pulsatile flow remains moderate (of order 10 mmHg), but that it can be improved by changing the relative shapes of the pressure and flow waves.
Nadir Oxygen Delivery During Pediatric Bypass as A Predictor of Acute Kidney Injury
The lowest suitable DO 2i during CPB in the present population undergoing pediatric cardiac surgery was 353 mL/min/m 2. And below this threshold, there was a high probability of inducing CS-AKI.
Tethered Liquid Perfluorocarbon Coating for 72 Hour Heparin-Free Extracorporeal Life Support
We conclude that neither TLP nor standard of care is an efficacious solution to prevent coagulation disturbances during ECLS. Further testing of promising biomaterials for ECLS utilizing the model outlined here is warranted.
Blood Cell Adhesion to Arterial Filters Analysis by Scanning Electron Microscopy and Real-Time PCR Assay: Observational Clinical Study in Cardiac Surgery Patients
There was adhesion of blood elements, especially nucleated platelets, on all arterial filters studied. Although the arterial filter worked as a safety device, that possibly prevented arterial embolisation, it may also have caused greater hyperfibrinolysis during cardiopulmonary bypass.
Dynamics of Appearance and Decay of Gaseous Microemboli During In Vitro Extracorporeal Circulation
We demonstrated GME formation and decay dynamics during in vitro circulation in an ECLS system with blood and glycerol. GME counts were higher in blood, likely due to varying rheological properties. There were decreases in GME levels post membrane in both groups after GME injection, with the membrane lung effectively trapping the GME, and additional reduction 10 minutes after GME injection.
Functional Brain Isolation Technique for Stroke Prevention in Thoracic Endovascular Aortic Repair
To prevent embolic stroke during thoracic endovascular aortic repair, we have adopted the brain isolation technique since June 2014 in 9 selected high-risk patients (9/134: 6.7%) having ulcerated or protruding atheromas within the proximal aorta.
Intraoperative Collection of Autologous Platelet-Rich Plasma from The Cardiopulmonary Bypass Circuit Upon Initiation of Extracorporeal Circulation
Autologous PRP can be safely collected by drawing blood from the CPB circuit, platelet count and aggregation ability significantly decreased after CPB including autologous PRP collection. Some improvement was detected in the number of the platelets count and platelet aggregation ability by administrating an autologous PRP even if autologous PRP is collected from CPB circuit.
Six-Month Survival After Extracorporeal Membrane Oxygenation for Severe COVID-19
The present findings suggested that about half of adult patients with severe COVID-19–related ARDS can be managed successfully with ECMO with sustained results at six months. Decreased arterial pH before ECMO was associated significantly with early mortality. Therefore, the authors hypothesized that initiation of ECMO therapy before severe metabolic derangements subset may improve survival rates significantly in these patients. These results should be viewed in the light of a strict patient selection policy and may not be replicated in patients with advanced age or multiple comorbidities.
VV ECMO Strategies for COVID-19, A Single Center Experience
Topics covered in this webinar included patient selection and management, cannulation preference, extracorporeal circuit design, staffing models and personal protective equipment.
Extracorporeal Membrane Oxygenation Support in Severe COVID-19
The early outcomes presented here suggest that the judicious use of ECMO support in severe COVID-19 may be clinically beneficial.
EACTA/SCA Recommendations for the Cardiac Anesthesia Management of Patients with Suspected or Confirmed COVID-19 Infection: An Expert Consensus from the European Association of Cardiothoracic Anesthesiology and Society of Cardiovascular Anesthesiologists with the endorsement from the Chinese Society of Cardiothoracic and Vascular Anesthesiology
Our document should be the basis of future Task Forces to develop a more comprehensive consensus considering new evidence uncovered during the COVID-19 pandemic.
Bedside Allogeneic Erythrocyte Washing with a Cell Saver to Remove Cytokines, Chemokines, and Cell-derived Microvesicles: A Clinical Feasibility Study
Bedside erythrocyte washing was clinically feasible and greatly reduced concentrations of soluble factors thought to be associated with transfusion-related adverse reactions, increasing concentrations of cell-free hemoglobin while maintaining acceptable (less than 0.8%) hemolysis.
