Hemodialysis Prescription

John T Daugirdas
BACKGROUND: Previous studies have suggested that a conventional two-pool model cannot be used to predict intradialysis and early postdialysis phosphorus concentrations. METHODS: A conventional two-pool urea model was modified by increasing the distal compartment volume from two-thirds to three times the total body water and by the use of a dynamically variable intercompartmental phosphorus clearance during dialysis. The phosphate solver model parameters were derived from an examination of the results in the literature, and fine-tuned using a training set (F4) of 415 Hemodialysis (HEMO) Study patients studied during a dialysis session where phosphorus was measured at 4 months of follow-up...

Renal replacement therapy is the indicated treatment for individuals with chronic kidney disease (CKD) to survive. However, not all sick people have access to the same treatment. This study compares renal care in two developing countries with different health systems. Specifically, it explores hemodialysis treatment from the perspective of low-income individuals. A qualitative, comparative study was performed in Brazil and Mexico. Using purposive sampling, the research was based on open-ended interviews with nineteen participants with kidney failure undergoing hemodialysis treatment in public hospitals and ten relatives...

BACKGROUND: Women and small men treated by hemodialysis (HD) have reduced survival. This may be due to use of total-body water (V) as the normalizing factor for dialysis dosing. In this study, we explored the equivalent dialysis dose that would be delivered using alternative scaling parameters matching the current recommended minimum Kt/V target of 1.2. STUDY DESIGN: Prospective cross-sectional study. SETTING & PARTICIPANTS: 1,500 HD patients on a thrice-weekly schedule, recruited across 5 different centers...

BACKGROUND: Stroke prevention in dialysis-dependent patients with atrial fibrillation (AF) is an unresolved clinical dilemma. Indeed, no randomized controlled trial evaluating the efficacy and safety of oral anticoagulants in this population, has been conducted so far. Observational research on the use of warfarin in patients on dialysis has shown conflicting results. This uncertainty is mirrored by the wide variations in warfarin prescription patterns across centers. We sought to evaluate the association between the use of vitamin K antagonists (VKAs) and mortality among hemodialysis patient with AF and to assess potential factors affecting the risk-benefit profile of warfarin in this population...

The kinetics of uremic solute clearances are discussed based on two categories of uremic solutes, namely those that are and those that are not derived directly from nutrient intake, particularly dietary protein intake. This review highlights dialysis treatments that are more frequent and longer (high-dose hemodialysis) than conventional thrice weekly therapy. It is proposed that the dialysis dose measures based on urea as a marker uremic solute, such as Kt/V and stdKt/V, be referred to as measures of dialysis inadequacy, not dialysis adequacy...

PURPOSE: Hemodialysis is the common kidney replacement therapy in Iran. Doing an adequate and effective dialysis can improve patients' quality of life and reduce kidney failure complications. Additionally, dialysis quality is an important factor in reducing mortality in patients with chronic kidney failure. This systematic review has investigated the adequacy of dialysis in studies done on hemodialysis patients of Iran. MATERIALS AND METHODS: All articles related to the dialysis adequacy in hemodialysis patients in English and Farsi (contemporary Persian) were identified by searching the related keywords in various electronic databases...

BACKGROUND: Chronic hemodialysis (HD) in the 1960s encompassed a wide variety of prescriptions from twice weekly to five times per week HD. Over time, HD prescriptions in the West became standardized at three times per week, 2.5-4 h per session, with occasional additional treatments for volume overload. SUMMARY: When clinical trials of dialysis dose failed to show significant benefit of extending time compared with the traditional dialysis prescription, interest in more frequent HD was renewed...

Conventional hemodialysis, which is based on the diffusive transport of solutes, is the most widely used renal replacement therapy. It effectively removes small solutes such as urea and corrects fluid, electrolyte and acid-base imbalance. However, solute diffusion coefficients decreased rapidly as molecular size increased. Because of this, middle and large molecules are not removed effectively and clinical problem such as dialysis amyloidosis might occur. Online hemodiafiltration which is combined by diffusive and convective therapies can overcome such problems by removing effectively middle and large solutes...

The management of the pain therapy (ischemic pain, neoplastic pain) in hemodialysis patients has become a frequent challenge in the last years. These patients often require the prescription of major analgesic drugs such as Opioids like Fentanyl, in order to control the pain. It is necessary to pay attention to the correct dosage and to the half life of these drugs, that results prolonged in the chronic renal insufficiency. The main side effect of opioids is respiratory depression which is well known, however, up to date, there is a lack of reports about other less frequent side effects, such as epilepsy or status epilepticus, in the literature...

Introduction Higher calcium dialysate is recommended for quotidian nocturnal hemodialysis (NHD) (≥6 nights/week) to maintain bone health. It is unclear what the optimal calcium dialysate concentration should be for alternate night NHD. We aimed to determine the effect of low calcium (LC) versus high calcium (HC) dialysate on cardiovascular and bone parameters in this population. Methods A randomized controlled trial where participants were randomized to LC (1.3 mmol/L, n = 24) or HC dialysate (1.6 or 1...

PURPOSE: Missed in-center hemodialysis treatments (MHT) are a general indicator of health status in hemodialysis patients. This analysis was conducted to estimate the association between cinacalcet use and MHT rate. METHODS: We studied patients receiving hemodialysis and prescription benefits services from a large dialysis organization. Incident cinacalcet users were propensity score matched to controls on 31 demographic, clinical, and laboratory variables. We applied inverse probability (IP) of censoring and crossover weights to account for informative censoring...

BACKGROUND: The degree to which the dialysate prescription and, in particular, the dialysate sodium concentration influences blood pressure and interdialytic weight gain (IDWG) via changes in sodium flux, plasma volume or the other parameters is not well understood. The aim of the study was to investigate whether dialysis patients will have some beneficial effects of dialysate sodium set up according to serum sodium or sodium modeling. MATERIAL AND METHODS: Ninety-two nondiabetic subjects (52 men and 40 women) performed 12 consecutive hemodialysis (HD) sessions (4 weeks) with dialysate sodium concentration set up on 138 mmol/L (standard sodium - first phase), followed by 24 sessions (second phase) wherein dialysate sodium was set up according to individualized sodium...

Introduction This study assessed the feasibility and efficacy of a novel resistance training device used within an intradialytic progressive resistance training (PRT) intervention. Methods Non-randomized, within-subjects crossover design with outcomes assessed at baseline (week 0), postcontrol (week 13) and post-PRT intervention (week 26). Twenty-two hemodialysis patients (59% men, 71 ± 11 years) performed PRT three sessions per week for 12 weeks. The resistance training device was developed to enable the performance of 2 upper body and 3 lower body exercises, unilaterally and bilaterally, both before and during dialysis, with loads of 2...

This report describes the first case of uninterrupted peritoneal dialysis (PD) after robotic-assisted laparoscopic hysterectomy. Frequent low-volume PD exchanges in a supine position to minimize intra-abdominal pressure starting on post-operative day 3 successfully provided adequate clearance and ultrafiltration. The patient did not encounter any metabolic or wound complications. Pre-admission PD prescription was resumed on post-operative day 14. Interim hemodialysis was not needed.

BACKGROUND: Dietary restriction and phosphate binders are the main interventions used to manage hyperphosphatemia in people on hemodialysis, but have limited efficacy. Modifying conventional dialysis regimens to enhance phosphate clearance as an alternative approach remains relatively unstudied. METHODS: This was a 10-week, 2-arm, randomized crossover study. Participants were prevalent dialysis patients (n = 32) with consecutive serum phosphate levels >1.6 mmol/L and on stable doses of a phosphate binder...
