Comparison of Microcirculatory Perfusion in Obese and Non-Obese Patients Undergoing Cardiac Surgery with Cardiopulmonary Bypass
Microcirculatory perfusion did not differ between obese and lean patients the day before surgery. CPB decreased microcirculatory perfusion with 9% in both groups, but this was only significant in lean patients (p < 0.05). Three days following surgery, microcirculatory perfusion was restored in both groups. In conclusion, microcirculatory perfusion was equally disturbed during cardiac surgery with CPB in metabolically healthy obese patients compared to lean patients.
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.
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.
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.
Clinical and Technical Limitations of Cerebral and Somatic Near-Infrared Spectroscopy as an Oxygenation Monitor
This narrative review explores those clinical and technical limitations and proposes solutions and alternatives in order to avoid some of those pitfalls.
The Hemovent Oxygenator: A New Low-Resistance, High-Performance Oxygenator
The aim of the current animal study was to evaluate the pressure gradient across the oxygenator and the gas exchange performance within a blood flow rate (BFR) range of 1–4 L/min, typically used in clinical practice for ECMO and ECCO2R.
Modified Ultrafiltration Reduces Postoperative Blood Loss and Transfusions in Adult Cardiac Surgery: A Meta-Analysis of Randomized Controlled Trials
MUF is a safe and feasible option in adult cardiac patients, with significant benefits including improved postoperative haematocrit, as well as reduced postoperative chest tube bleeding, transfusion requirements and duration of ICU stay.
Hemadsorption
An evidence-based and personalized approach to EBPTs in sepsis is strongly advocated, in order to solve controversies in this field and optimise the management of critically ill septic patients.
Outcomes after Intra-Aortic Balloon Pump Insertion in Cardiac Surgery Patients
Preoperative insertion of an intra-aortic balloon pump was not associated with a lower 30-day mortality or reduced length of postoperative hospital stay compared to intraoperative insertion.
Practical Clinical Application of an Extracorporeal Carbon Dioxide Removal System in Acute Respiratory Distress Syndrome and Acute on Chronic Respiratory Failure
A low-flow ECCO2R device with a large surface ML removes a relevant amount of CO2 resulting in a decreased arterial PCO2, an increased arterial pH, and in a reduced ventilatory load.
Mycobacterium Chimaera in Heater-Cooler Devices: An Experience in A Tertiary Hospital in Spain
Mycobacterium chimaera contamination is not always eradicated by disinfection processes. We believe that placing 3T heater–cooler devices outside the operating room is the best option in preventing M. chimaera infection during cardiac surgery.
