adequacy hemodialysis

INTRODUCTION: Hemodialysis (HD) units require large quantities of water. To reduce water consumption without compromising the adequacy and safety of dialysis, we studied a novel HD prescription with high temperature and low flow dialysate. METHODS: This was a single-center nonrandomized open-label cross-over pilot trial in patients with end-stage kidney disease on maintenance HD. Each participant was subjected to 3 different dialysis prescriptions for 1 month each as follows: (i) normal temperature with normal flow dialysate (NTNF prescription), (ii) high temperature with normal flow dialysate (HTNF prescription), and (iii) high temperature with low flow dialysate (HTLF prescription)...

BACKGROUND: The COVID-19 pandemic posed a challenge to hemodialysis (HD) patients. While most outpatient and elective medical services stopped during lockdown, HD patients continued to visit their dialysis centers. We aimed to assess how the initial phase of the pandemic affected patient care by comparing dialysis adequacy and other parameters of patient care before and during the first 10 months of the COVID-19 pandemic. METHODS: In a retrospective multi-center observational study, all adult dialysis patients in five dialysis centers in Alexandria, Egypt were included...

"Palliative dialysis" is defined as the renal replacement therapy directed to patients living the most critical phases of illness and the end-of-life stage. Offering targeted dialysis prescriptions becomes imperative when health conditions, along with comorbidities, unfavorable prognosis and complications, do not allow standard dialysis to be started or continued. Management should also integrate adequate supportive care measures in both incident and prevalent patients. This document summarizes nephrological recommendations and scientifical evidence regarding the palliative approach to dialysis, and proposes operative tools for a good clinical practice...

BACKGROUND: This study aims to assess the effect of needle distance of arteriovenous fistula (AVF) cannulation on haemodialysis adequacy based on KT/V. MATERIALS AND METHODS: This study was a parallel-group, randomized controlled trial. Patients who met the inclusion criteria were divided into two groups with 3 and 6 cm needle distances using block randomization. Data acquisition transpired through a comprehensive checklist encompassing demographic variables such as age and sex, alongside clinical metrics comprising actual weight, dry weight, average dialysis duration, fistula longevity, and KT/V rate...

RATIONALE & OBJECTIVE: Reasons for transfer from peritoneal dialysis (PD) to hemodialysis (HD) remain incompletely understood. Among incident and prevalent patients receiving PD, we evaluated the association between prior treatment with HD and PD technique survival. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: Adults who initiated PD at a Dialysis Clinic, Inc. (DCI) outpatient facility between January 1, 2010 and September 30, 2019...

BACKGROUND/AIMS: Intensive care unit (ICU) quality is largely determined by the mortality rate. Therefore, we aimed to develop and validate a novel prognostic model for predicting mortality in Korean ICUs, using national insurance claims data. METHODS: Data were obtained from the health insurance claims database maintained by the Health Insurance Review and Assessment Service of South Korea. From patients who underwent the third ICU adequacy evaluation, 42,489 cases were enrolled and randomly divided into the derivation and validation cohorts...

OBJECTIVE: To observe the multi-slice spiral CT angiography (MSCTA) imaging features of arteriovenous fistula dysfunction in patients undergoing maintenance hemodialysis and analyze the significance of the imaging examination. METHODS: Altogether 90 patients with end-stage renal disease treated by maintenance hemodialysis in General Hospital of China Resources & Wisco from June 2020 to February 2023 were divided into a normal function group (n=68) and a dysfunction group (n=22) according to the function of autogenous arteriovenous fistula...

BACKGROUND: The single-pool model urea clearance index (single-pool Kt/Vurea ; spKt/V) is the most commonly used method for dialysis adequacy assessment. However, only a few studies have examined the relationship between spKt/V values and parameters related to sarcopenia and nutritional status. This study aimed to evaluate whether the spKt/V is an indicator of sarcopenia and nutritional status in patients undergoing maintenance hemodialysis (MHD). METHODS: A total of 142 patients were included in this single-center, cross-sectional study...

Background Frequent assessment of the dialysis dose delivered to hemodialysis patients might help improve morbidity and mortality. Daugirdas' second-generation formula is the recommended method for calculating dialysis doses. However, urea reduction ratios (URRs) and online clearance monitors (OCMs) are frequently used to assess dialysis adequacy due to their more straightforward concept and ease of use. This study was conducted to determine the most reliable method for measuring dialysis adequacy by comparing the correlation of urea reduction ratio and online clearance monitor measurements with the dialysis dose measured using the recommended Daugirdas' second-generation formula...

BACKGROUND: Hemodialysis (HD) patients have higher risks of cardiovascular morbidity and mortality compared to the general population. Cardio-femoral pulse wave velocity (cfPWV) is associated with cardiovascular morbidity and mortality in HD patients. This study aimed to evaluate the prevalence and associated factors of arterial stiffness in Thai HD patients. MATERIALS AND METHODS: This cross-sectional multicenter study was conducted at 4 HD centers in Bangkok, Thailand...

Unfractionated heparin (UFH) and low-molecular-weight heparins (LMWHs) are commonly used to prevent clotting of the hemodialysis extracorporeal circuit and optimize hemodialysis adequacy. There is no consensus on the optimal dosing for UFH and LMWHs during hemodialysis. In clinical practice, semiquantitative clotting scoring of the dialyzer and venous chamber may help to guide UFH and LMWH dose adjustment. Laboratory monitoring has not been shown to improve clinical outcomes and is therefore not routinely indicated in most hemodialysis patients...

Korean Renal Data System (KORDS) is a nationwide end-stage renal disease (ESRD) registry database operated by the Korean Society of Nephrology (KSN). Diabetes mellitus is currently the leading cause of ESRD in Korea; this article provides an update on the trends and characteristics of diabetic ESRD patients. The KORDS Committee of KSN collects data on dialysis centers and patients through an online registry program. Here, we analyzed the status and trends in characteristics of diabetic chronic kidney disease stage 5D (CKD 5D) patients using data from 2001 to 2021...

OBJECTIVES: Urea and creatinine concentrations in plasma are used to guide hemodialysis (HD) in patients with end-stage renal disease (ESRD). To support individualized HD treatment in a home situation, there is a clinical need for a non-invasive and continuous alternative to plasma for biomarker monitoring during and between cycles of HD. In this observational study, we therefore established the correlation of urea and creatinine concentrations between sweat, saliva and plasma in a cohort of ESRD patients on HD...

Clotting of the extracorporeal circuit is a complication in the process of hemodialysis that can result in missed or shortened dialysis sessions, higher nursing workload, and elevated cost of treatment. Repercussions of inadequate dialysis may include patient blood loss, fluid overload, build-up of minerals, higher hospitalization rates, and poor quality of life, contributing to increased patient distress. Preventing clotting through anticoagulation therapy is the key to maintaining patency of the dialysis circuit and supporting dialysis adequacy...

BACKGROUND: Citrate dialysate (CD) has been successfully used in conventional hemodialysis and continuous renal replacement therapy; however, no study has compared pre- and post-dilution online hemodiafiltration (oL-HDF). Therefore, we aimed to investigate the efficacy of citrate anticoagulation for oL-HDF and the metabolic changes and quality of life of patients on hemodialysis treated using both modes. METHOD: Eight dialysis patients were treated with CD containing 0...
