Filter by:The goal of this clinical trial was to compare the efficiencies of bioelectrical impedance analysis (BIA) measurement frequency in preventing intradialytic hypotension in end-stage renal disease (ESRD) patients undergoing regular hemodialysis. The main question aimed to answer about the optimum frequency of BIA measurements to prevent intradialytic hypotension. Participants underwent BIA measurements to determine their appropriate dry weight, and factors affecting intradialytic hypotension. Researchers compared the efficiencies of BIA measurements between the every-1-month group and the every-2-month group to prevent intradialytic hypotension.
Intradialytic hypotension (IDH) is a common complication during hemodialysis in patients with chronic kidney disease and may increase the mortality. This study aimed to investigate whether pulse wave analysis could be the predictor of IDH. In this study, patients under regular hemodialysis were enrolled from Taoyuan Chang Gung memorial hospital. Subjects were evaluated by pulse wave instrument, heart rate variability analyzer and Constitution in Chinese Medicine Questionnaire before hemodialysis. According to the definitions of IDH, subjects in study group and control group were confirmed by the dialysis records. Furthermore, repeated examinations were done for 3 hemodialysis to investigate the possible predictive factors for IDH.
This study was designed to compare the efficacy of BIA and physician adjustment to prevent intradialytic hypotension in patients with acute kidney injury who received renal replacement therapy. The investigators randomized 9 patients with acute kidney injury and volume overloaded who underwent acute hemodialysis for 45 sessions in Vajira hospital between October 2017 and February 2018. In physician adjust-group (control) estimate by physical examination and fluid balance record. Primary outcome was intradialytic hypotensive episode and secondary outcome was hemodialysis-related adverse events and other clinical outcome.
The objective of this study is to compare the rate of low blood pressure events (Intradialytic Hypotension: IDH) when intradialytic exercise is performed in the first half of the hemodialysis (HD) session as compared to that when intradialytic exercise is performed in the second half of the HD session. The investigators expect that there will be little to no difference in occurrence of IDH episodes between the two time periods based on the experience of the 3 centres and imaging studies of the heart with exercise in HD.
Online hemodiafiltration confers a reduced mortality risk. However, it is not clear why HDF improved survival. To gain more insight in this issue, the effect of 4 dialysis techniques (differing in dialysate temperature and the absence/presence of convective clearance) on intradialytic hemodynamic stability and cardiac function will be investigated in a prospective cross over trial.
Immersion to the neck before and during hemodialysis session may increase intravascular volume, potentiate the ability to ultrafiltrate excess water, with less symptoms of shock, muscle crumps etc. The aim of the present study is to compare blood volume, hemodynamic and endocrine parameters of chronic ESRD patients undergoing forth dialysis session in water immersion vs. control regular session.
Rationale and objectives 1. Patients on On Line Hemodiafiltration (OL- HDF) are more stable hemodynamically with less Intra Dialytic Hypotension (IDH) episodes compared to conventional hemodialysis (HD). The investigator will follow the hemodynamic parameters during the dialysis sessions (HD and OL-HDF) by using the new non invasive technology, the NICAS device. 2. By switching each patient with IDH from HD to OL- HDF, the investigators will evaluate the hemodynamic parameters and compare the two renal replacement treatment modalities, and prove the superiority of OL-HDF over HD regarding the hemodynamic measures.
The purpose of this study is to use the photo-plethysmographic [PPG] waveform signal to guide the dialysis and ultrafiltration [UF] of chronic maintenance hemodialysis patients, and to further the investigators understanding of homeostasis in hemodialysis. The investigators hypothesize that the signals generated from the PPG device along with traditional monitoring and nursing judgment, will allow experienced, oriented staff to anticipate hemodynamic instability, intervene to prevent or mitigate the intradialytic hypotention [IDH], forestalling the onset of non-facilitating compensatory reflexes that preclude the patient from achieving an appropriate post-dialysis weight consistent with euvolemia. Furthermore, it is hypothesized that the nephrologist and staff will be able to wean patients from anti-hypertensive medications and craft patient specific dialysis orders and UF profiles that achieve consistent, comfortable treatment to appropriate end points. The study aims include: Aim 1: To confirm the temporal sequence of PPG signals and changes in BP in routine hemodialysis. Aim 2: To refine further the predictive algorithms of PPG, augmented with continuous cardiac event monitoring (pre-intra-post hemodialysis) Aim 3: To develop targeted interventions to reverse the cardiovascular stress indicated by the PPG and to maintain perfusion. Aim 4: To develop care paths approved by the medical staff and primary care nephrologist allowing RNs to respond to signals from the PPG.
Hemodialysis (HD) patients with end stage renal disease (ESRD) experience higher rates of cardiovascular (CV) morbidity and mortality than do the general population and many populations with other chronic diseases. This exceptional risk is explained in part by known risk factors, such as diabetes, hypertension, and other uremia-related factors, including vascular calcification and stiffness, autonomic dysfunction, and a high burden of circulating inflammatory mediators. Recent studies suggest that blood pressure variability, especially intra-dialytic hypotension (IDH) is the most significant risk factor for these CV events. Studies have also shown that the use of IAB is capable of improving cardiovascular function for avoiding or minimizing the development of an orthostatic hypotensive episode (OHE) in patients with autonomic dysfunction, orthostatic hypotension (OH) in diabetes patients and children with orthostatic intolerance, and post-dialytic orthostatic hypotension (PDOH). The investigators propose a study to examine the use of an abdominal compression elastic support (ACES) to prevent the development of IDH in patients who are known to be prone to these episodes. The ultimate goal is to facilitate more effective and safer dialysis therapy. The ACES has a configuration that is similar to a back-support work belt or an inflatable abdominal band (IAB). All of these devices are wrapped around to compress the abdomen at the waist.
As kidney function declines, the ability to maintain water balance is impaired and is most often treated with hemodialysis. The removal of excess water in hemodialysis often leads to a sudden drop of blood pressure and causes symptoms of dizziness, light-headedness, cramping, and chest pain. This sudden drop in blood pressure has been linked with complications of heart attacks, strokes and even death. Research has focused on different ways to prevent dangerous drops in blood pressure during hemodialysis. One way is the use of blood volume monitoring biofeedback technology to monitor the patient's relative blood volume and automatically reduce the amount of fluid that is being removed when the blood volume is low to prevent the drop in blood pressure from occurring. This type of biofeedback device is currently available on some hemodialysis machines and while this approach appealing, it is not clear how effective this form of biofeedback is in preventing the drops in blood pressure. We plan to determine if the use of biofeedback based on the changes in the patient's blood volume will reduce the number of sudden drops in blood pressure that occur during hemodialysis. To do this, we will compare patients treated with this technology to current hemodialysis practices and follow them for important adverse outcomes. The result of interest will be the frequency of hemodialysis sessions complicated by a sudden symptomatic drop in blood pressure. We also plan to monitor the amount of water in the different body compartments, blood pressure, blood pressure medication use, markers of heart function, and patient symptoms and quality of life. We hope that by providing information on this technology we can reduce the sudden drops in blood pressure in hemodialysis, the associated rates of serious disease or death, and improve patient quality of life.
