hemodialfiltration

The objective of this case report is to describe the use of extracorporeal therapy, specifically hemodialfiltration, for the treatment of caffeine intoxication. A 12 year old Border Terrier consumed up to 1440 mg/kg of caffeine and rapidly developed clinical signs of tachycardia and tremors. Hemodiafiltration was instituted, using an M60 PrismaFlex cartridge using blood to prime the system due to patient size. Treatment with 11.25 L of therapy fluid (83% dialysate, 17% replacement fluid), or 1.8 L/kg, was provided over 6 h...

On-line hemodiafiltration is an increasingly common alternative to chronic hemodialysis in some countries, based on the results of randomized controlled trials of post-dilution on-line hemodiafiltration. There are now more than 60,000 patients treated with on-line hemodialfiltration in Japan, over 95% of whom use predilution on-line hemodiafiltration; however, large-scale data on clinical outcomes with this modality are lacking. We created a propensity-matched cohort of 5,000 pairs of patients treated with conventional hemodialysis or predilution on-line hemodiafiltration, using the Japanese Society for Dialysis Therapy Renal Data Registry database from December 31, 2012 to December 31, 2013...

This report evaluates plasma protein patterns, dialysates and protein analysis of used dialysis membranes from the same patient under hemodialysis in three separate modalities, using high-flux membranes in concentration-driven transport (HD), convection-driven hemofiltration (HF) and combined hemodialfiltration (HDF). The plasma protein changes induced by each of the three dialysis modalities showed small differences in proteins identified towards our previous plasma analyses of chronic kidney disease (CKD) patients...

Some herbal medications induce acute kidney injury. The acute kidney injuries caused by herbal medications are mild and commonly treated by palliative care. A 51-years-old man who drank the juice squeezed from the raw tubers of Dioscorea quinqueloba (D. quinqueloba) was admitted with nausea, vomiting and chilling. He developed a seizure with decreased level of consciousness. He was diagnosed with acute kidney injury, which was cured by continuous venovenous hemodialfiltration. Non-detoxified D. quinqueloba can cause severe acute kidney injury with toxic encephalopathy...

BACKGROUND: To overcome the deleterious consequences of conventional dialysis, intensified dialysis programs have been developed and their feasibility and beneficial effects in children demonstrated. To investigate whether such a program can be further improved, we implemented hemodialfiltration within an established pediatric in-center, nocturnal hemodialysis program. METHODS: After being started on conventional hemodialysis (HD), seven patients were switched to intermittent nocturnal hemodialysis (NHD) for 3 months, then to intermittent nocturnal online-hemodiafiltration (NHDF) for a further 3 months and finally back to NHD...

Hemodialfiltration (HDF) has been reported to reduce the frequency of intradialytic hypotension compared with hemodialysis (HD). We wished to determine whether HDF resulted in improvement of arterial stiffness compared with HD. We reviewed peripheral blood pressure and pulse wave velocity measurements in a cross-sectional analysis of stable HDF and HD outpatients. One hundred forty-one HDF patients were matched to 148 HD patients in terms of age, sex, prevalence of diabetes, peripheral blood pressure, and body mass...

Intradialytic hypotension remains the most frequent complication associated with routine outpatient hemodialysis. Although increasing dialysis frequency and also lengthening dialysis session duration can reduce the risk of intradialytic hypotension, in practice, these options are limited to a small minority of dialysis patients. To help reduce intradialytic hypotension, a number of technological developments have been incorporated into the hemodialysis machine, based around relative blood volume monitoring, an indirect assessment of plasma volume...

BACKGROUND: Acute renal failure (ARF) is a common complication in critically ill children. It is known as an important predictor of morbidity and mortality in this population. Data on the factors affecting the choice of renal replacement therapy (RRT) modality and its impact on mortality of children with ARF are limited. OBJECTIVES: We retrospectively studied 115 children with ARF necessitating RRT during the period 1995-2005 to evaluate the effect of several prognostic factors as well as RRT type on their immediate outcome...

Systemic heparinization during continuous renal replacement therapy (CRRT) is associated with disadvantage of risk of bleeding. This study analyses the efficacy of frequent saline flushes compared with heparin anticoagulation to maintain filter life. From January 2004 to November 2007, 65 critically ill patients with acute renal failure underwent CRRT. Continuous venovenous hemodialfiltration (CVVHDF) was performed using Diapact Braun CRRT machine. 1.7% P.D. fluid was used as dialysate. 0.9% NS with addition of 10% Ca Gluconate, Magnesium Sulphate, Soda bicarbonate and Potassium Chloride added sequentially in separate units were used for replacement, carefully monitoring their levels...

Today hemodialysis is a routine outpatient treatment, not only carried out in hospitals, but more commonly in free standing units without on site medical supervision. One of the key advances that have underpinned this expansion of hemodialysis provision has been the technological advances in dialyzer membrane technology. Dialyzer membranes have undergone a sea change from collodion tubes to cellulose sheets to the modern day capillary fiber dialyzer. Improvements have not only been limited to reliability of manufacture, but also reduction in bio-incompatibility, and improved small solute clearances...

The biologic response to uremia and to the associated chronic inflammation is an active area of research. Among the different modalities developed in the technology field of chronic renal replacement, hemodialfiltration has evolved consistently. On-line production of substitution fluid by 'cold sterilization' of dialysis fluid by ultrafiltration gives access to virtually an unlimited amount of sterile and non-pyrogenic intravenous grade solution. Today, on line HDF is already a widespread, accepted treatment...

Over the last years, the nursing profession has witnessed major changes because of the new regulations that apply to this healthcare field. In order to outline the role of nurses in managing the sophisticated equipment for critically ill patients hospitalized in a coronary care unit, these new regulations should be taken into consideration. At present, the current deontological code defines the reference criteria for defining nurse's competence, responsibilities and actions, and for which education and updating are necessary...

The study evaluates the potential of high ultrafiltration on-line hemodialfiltration (HDF) as a means of achieving the goals of extracorporeal RDT: the removal of small and medium-sized molecules, vascular stability and biocompatibility. The removal of small molecules was correlated with the UF rate and therefore with reinfusate volume. Medium-sized molecules were only removed from high permeability synthetic membranes in HD, but to a greater extent in HDF because of higher absorption. Vascular stability during the dialytic session is improved by convective processes, as is confirmed by a low prevalence of arterial hypertension in HDF patients...

BACKGROUND/AIMS: In spite of the better efficiency of on-line hemodiafiltration (HDF) compared with conventional hemodialysis (HD), it is relatively expensive. The aim of this study was to assess the advantages in the biochemical, hemodynamic and clinical effects in uremic patients treated with on-line HDF and with different frequencies of combination high-flux HD. METHODS: One hundred eleven patients were divided into four groups receiving different frequencies of on-line HDF (thrice, twice, once per week) and high-flux HD...

Acute renal failure (ARF) associated with liver disease is a commonly encountered clinical problem of varied etiology and high mortality. We have prospectively analyzed patients with liver disease and ARF to determine the etiology, clinical spectrum, prognosis and factors affecting the outcome. Other than hepatorenal syndrome patients, out of 221 cases, 66 developed ARF secondary to various liver disease like cirrhosis (n = 29, mortality 8, risk factors-older age p < 0.01, grade III/IV encephalopathy p < 0...

OBJECTIVES: To determine whether continuous venovenous hemodialfiltration (CVVHD) is associated with the extraction of interleukin-6 (IL-6) and interleukin-8 (IL-8) from the circulation of critically ill patients with septic acute renal failure. To quantitate their clearance and assess any possible effect of CVVHD on these cytokines' serum concentrations. DESIGN: Prospective controlled study of IL-6 and IL-8 removal by CVVHD in patients with septic acute renal failure...

Based on the concept that an optimisation of dialysis therapy might be achieved by increasing the removal of small metabolic substances as well as low molecular weight proteins, hemodialfiltration (HDF) was modified. In 9 ESRD patients, HDF was performed acutely for 4 h, where 60 liters of substitution fluid were infused per patient. Two polysulphone F60 membranes in line were used as hemodialfilters. As compared to conventional hemodialysis (HD), performed with a cuprophane dialyser, HDF resulted in higher extraction indices for small solutes assessed by HPLC...
