Abstract Background The importance of assessing venous congestion in ICU patients is widely acknowledged, but its study hampered by the lack a practical evaluation tool. Venous Excess Ultrasound Grading System (VExUS), based on semi-quantitative combined ultrasound assessment, has been associated with acute kidney injury (AKI) cardiac patients. objectives this were to assess prevalence using VExUS general patients, and evaluate association between VExUS, AKI death. Methods This prospective,...

Abstract Background Fluid overload and venous congestion are associated with morbi-mortality in the ICU (intensive care unit). Administration of diuretics to correct fluid balance is common, although there no strong relationship between consequent loss clinical improvement. The aim study was evaluate ability portal pulsatility index, renal impedance VEXUS score (venous ultrasound score) predict appropriate diuretic-induced depletion. Methods had a prospective, observational, single-center...

Purpose Cardiac surgery with cardiopulmonary bypass triggers sterile inflammation that is responsible for post-operative morbidity. Automated flow cytometry devices used leucocyte count provide cell population data (CPD) regarding fluorescence intensity, size and granularity of leukocytes have never been studied in the context inflammation. Our objective was to explore leukocyte patients undergoing cardiac order determine whether CPD could be monitor immune activation. Methods This an...

Pupillometry has proven effective for the monitoring of intraoperative analgesia in non-cardiac surgery. We performed a prospective randomized study to evaluate impact an analgesia-guided pupillometry algorithm on consumption sufentanyl during cardiac Fifty patients were included prior General anesthesia was standardized with propofol and target-controlled infusions sufentanyl. The standard group consisted target infusion left discretion anesthesiologist. intervention based pupillary pain...

Introduction: Lipopolysaccharide (LPS) is a component of gram-negative bacteria, known for its ability to trigger inflammation. The main pathway LPS clearance the reverse lipopolysaccharide transport (RLT), with phospholipid transfer protein (PLTP) and lipoproteins playing central roles in this process experimental animal models. To date, relevance has never been studied humans. Cardiac surgery cardiopulmonary bypass favor digestive translocation. Our objective was determine whether...
