CONCLUSION: Cannulation trauma at the initiation of haemodialysis could potentially be reduced with a strategy of incremental haemodialysis using single-needle treatment supported with duplex ultrasonography assessment to 'map' the vascular access as a guide for clinicians prior to cannulation initiation.

ández M, Ortiz A Abstract Patients with chronic kidney disease (CKD) are at an increased risk of premature mortality, mainly from cardiovascular causes. The association between CKD on hemodialysis and accelerated atherosclerosis was described>40 years ago. However, more recently, it has been suggested that the increase in atherosclerosis risk is actually observed in early CKD stages, remaining stable thereafter. In this regard, interventions targeting the pathogenesis of atherosclerosis, such as statins, successful in the general population, have failed to benefit patients with very advanced CKD. This ra...

Authors: Tessitore N, Lipari G, Contro A, Moretti F, Mansueto G, Poli A Abstract INTRODUCTION: Guidelines recommend hemodialysis graft screening to identify and repair significant (>50%) stenosis at high risk of thrombosis, but there is insufficient evidence to prefer one or other screening tool due to the lack of studies comparing all available options. METHODS: Seeking an optimal screening approach, we compared the performance of all currently used tools (duplex ultrasound to detect significant stenosis (StD) and measure access blood flow (QaD), ultrasound dilution access blood flow (QaU), static venous in...

Introduction: Peripheral, ultrasound-guided intravenous (IV) access occurs frequently in the emergency department, but certain populations present unique challenges for successfully completing this procedure. Prior research has demonstrated decreased compressibility under double tourniquet technique (DT) compared with single tourniquet (ST). We hypothesized that catheters inserted under DT method would have a higher first-stick success rate compared with those inserted under ST method.Methods: We randomized 100 patients with a history of difficult IV access, as defined by past ultrasound IV, prior emergency visit with two ...

Authors: Mateos Torres E, Collado Nieto S, Cao Baduell H, Lacambra Peñart M, Velescu A, Clará Velasco A Abstract INTRODUCTION: Traditionally, the indication of the type of vascular access (VA) has been based on the surgeon's physical examination, but it is now suggested that imaging methods could provide a clinical benefit. Our aim was to determine whether or not preoperative Doppler ultrasound modifies outcomes of the first VA for haemodialysis. PATIENTS AND METHODS: Prospective cohort of patients undergoing a first VA from June 2014 to July 2017 who had a preoperative Doppler ultrasound (ECO gro...

In this study, a newly-developed PPG sensor device was utilized to provide patients and doctors with an inexpensive and small-sized solution for ubiquitous AVF assessment. The readout in this sensor was custom-designed to increase the signal-to-noise ratio (SNR) and reduce the environment interference via maximizing successfully the full dynamic range of measured PPG entering an analog–digital converter (ADC) and effective filtering techniques. With quality PPG measurements obtained, machine learning classifiers including SVM were adopted to assess AVF quality, where the input features are determined based on opt...

Rationale: Twin pregnancy in women with chronic kidney disease (CKD) is very rare but poses a great risk to both mother and children. In developing countries like China, advanced CKD twin pregnancies are often terminated. Here, we report a successful case and reviewed related cases, hope to facilitate further study. Patient concerns: A 29-year-old woman with a twin pregnancy showed serum creatinine (Scr) 100 μmol/L (CKD2) at conception. During her 12th week, Scr reached 263 μmol/L (CKD4) with urine protein 3+ and hypertension. Diagnoses: Due to her pregnancy, renal biopsy was not considered. Lab tests sho...

This study is an observational and cross-sectional study including 62 patients with normotensive chronic hemodialysis using no antihypertensive drugs. A series of measurements including ambulatory blood pressure monitoring, left ventricular mass index by echocardiography, common carotid artery intima-media thickness by ultrasound, and body fluids by bioimpedance analysis were conducted for all subjects. Results: The patients were divided into two groups as dippers and nondippers according to their ambulatory blood pressure monitoring results. Average 48 h systolic, diastolic, and mean arterial blood pressure and noctur...

ConclusionPreviously dialysis was standard, currently it is oriented by efficiency criteria. The ascension of the PA paralyzial is a paradox and several factors are incriminated: water overload, fast UF, short sessions, arterial rigidity, anemia. The use of an ideal dry weight and long hemodialysis allows a Significant improvement in blood pressure control through better control of extracellular volume (ECV). In addition, there is a lack of morbidity and mortality studies among dialysis patients as well as a clear definition of blood pressure targets in this group of patients forgotten by the studies.
