Abstract Background Organ congestion is a mediator of adverse outcomes in critically ill patients. Point-Of-Care ultrasound (POCUS) widely available and could enable clinicians to detect signs venous at the bedside. The aim this study was develop several grading system prototypes using POCUS determine their respective ability predict acute kidney injury (AKI) after cardiac surgery. This post-hoc analysis single-center prospective 145 patients undergoing surgery for which repeated daily...
Background Acute kidney injury ( AKI ) after cardiac surgery is associated with adverse outcomes. Venous congestion can impair function, but few tools are available to assess its impact at the bedside. The objective of this study was determine whether portal flow pulsatility and alterations in intrarenal venous assessed by Point‐Of‐Care ultrasound surgery. Methods Results This single‐center prospective cohort recruited patients undergoing cardiopulmonary bypass. Hepatic renal Doppler...
Abstract The importance of functional right ventricular failure and resultant splanchnic venous congestion has long been under-appreciated is difficult to assess by traditional physical examination standard diagnostic imaging. recent development the excess ultrasound score (VExUS) growth point-of-care in last decade made for a potentially very useful clinical tool. We review rationale its use several pathologies illustrate with cases where VExUS was pivotal management.
Hemodialysis patients are at increased risk for coronavirus disease 2019 (COVID-19) transmission due in part to difficulty maintaining physical distancing. Our hemodialysis unit experienced a COVID-19 outbreak despite following symptom-based screening guidelines. We describe the course of and infection control measures taken mitigation.
Portal venous flow pulsatility detected by Doppler ultrasound is a sign of congestive heart failure in noncritically ill patients. The assessment portal and splenic flows has never been reported patients undergoing cardiac surgery.This case series performed surgery between February 2014 2015 which and/or were assessed the attending anesthesiologist during or intensivist after using transthoracic echography 9 transesophageal echocardiography 5 Data collection was done retrospectively...
<h3>BACKGROUND:</h3> Patients receiving in-centre hemodialysis are at high risk of exposure to SARS-CoV-2 and death if infected. One dose the BNT162b2 vaccine is efficacious in general population, but responses patients uncertain. <h3>METHODS:</h3> We obtained serial plasma from health care worker controls before after vaccination with 1 mRNA vaccine, as well convalescent who survived COVID-19. measured anti–receptor binding domain (RBD) immunoglobulin G (IgG) levels stratified groups by...
Introduction Venous congestion is a pathophysiological state where high venous pressures cause organ oedema and dysfunction. associated with worse outcomes, particularly acute kidney injury (AKI), for critically ill patients. can be measured by Doppler ultrasound at the bedside through interrogation of inferior vena cava (IVC), hepatic vein (HV), portal (PV) intrarenal veins (IRV). The objective this study to quantify association between identified need renal replacement therapy (RRT) or...
Abstract Background During cardiac surgery, transcranial Doppler (TCD) represents a non-invasive modality that allows measurement of red blood cell flow velocities in the cerebral arteries. TCD can also be used to detect and monitor embolic material circulation. Detection microemboli is reported as high intensity transient signal (HITS). The importance during surgery has been linked increased incidence postoperative renal failure, right ventricular dysfunction, hemodynamic instability....
Abstract Background Cardiorenal syndrome poses significant diagnostic and therapeutic challenges. The Venous Excess Ultrasound (VExUS) grading system based on the combination of venous Doppler assessments has shown potential in predicting acute kidney injury cardiovascular outcomes, but its relevance regarding management acutely decompensated heart failure (ADHF) remains to be fully understood. Methods In this prospective study, patients with ADHF (AKI) were enrolled from a medical intensive...
Objectives: To report the use of common femoral vein Doppler interrogation as a simple technique to diagnose right ventricular dysfunction. Design: Case report. Setting: Cardiac surgical ICU. Patients: Postoperative cardiac patients. Interventions: Common pulsed-wave and color examination associated with hepatic, portal, renal venous measurement were obtained in both patients before after treatment patient number 1. In addition, pressure waveform was 2. Measurements Main Results: The obtain...
Background In critically ill patients receiving KRT, high ultrafiltration rates and persistent fluid accumulation are associated with adverse outcomes. The purpose of this international survey was to evaluate current practices evidence gaps related removal KRT in patients. Methods This a multinational, web-based distributed by seven networks comprising nephrologists intensivists. Physicians involved the care were invited complete 39-question about management on KRT. from September 2021...
IntroductionOrgan congestion may be a mediator of adverse outcomes in critically ill patients with severe acute kidney injury (AKI). The presence abnormal venous Doppler waveforms could identify clinically significant organ who benefit from decongestive strategy.MethodsThis prospective multicenter cohort study enrolled AKI defined as KDIGO stage 2 or higher. Patients were not eligible if they received renal replacement therapy (RRT) for more than 72 hours at the time screening. Participants...
Missing preadmission serum creatinine (SCr) values are a common obstacle to assess acute kidney injury (AKI) diagnosis and outcomes. The Kidney Disease Improving Global Outcomes (KDIGO) guidelines suggest using SCr computed from the Modification of Diet in Renal (MDRD) with an estimated glomerular filtration rate 75 ml/min/1.73 m2. We aimed identify best surrogate method for baseline AKI compared use 1) first at hospital admission 2) minimal over 2 weeks after intensive care unit 3) MDRD 4)...
Abstract Background Among critically ill patients with acute kidney injury (AKI), earlier initiation of renal replacement therapy (RRT) may mitigate fluid accumulation and confer better outcomes among individuals greater overload at randomization. Methods We conducted a pre-planned post hoc analysis the STandard versus Accelerated Renal Replacement Therapy in Acute Kidney Injury (STARRT-AKI) trial. evaluated effect accelerated RRT on cumulative balance over course 14 days following...
