INTRODUCTION: Intradialytic hypotension (IDH) has been reported in 15% to 50% of hemodialysis patients and increases patients morbidity and mortality. Some small noncontrolled studies evaluated the effect of sertraline on IDH with conflicting results. This study is a randomized crossover controlled trial on the effectiveness of sertraline to reduce IDH. MATERIALS AND METHODS: Patients on hemodialysis who suffered IDH in at least 50% of their dialysis sessions were enrolled...

Prolonged intermittent renal replacement therapy (PIRRT) has emerged as an alternative to continuous renal replacement therapy in the management of acute kidney injury (AKI) patients. This trial aimed to compare the dialysis complications occurring during different durations of PIRRT sessions in critically ill AKI patients. We included patients older than 18 years with AKI associated with sepsis admitted to the intensive care unit and using noradrenaline doses ranging from 0.3 to 0.7 µg/kg/min. Patients were divided into two groups randomly: in G1, 6-h sessions were performed, and in G2, 10-h sessions were performed...

This trial aimed to compare the dialysis complications occurring during different durations of extended daily dialysis (EDD) sessions in critically ill AKI patients. We included patients older than 18 years with AKI associated with sepsis admitted to the intensive care unit and using noradrenaline dose ranging from 0.3 to 0.7 μg/kg/min. Patients were divided into two groups randomly: in G1, 6 h sessions were performed and, in G2, 10 h sessions were performed. Seventy-five patients were treated with 195 EDD sessions for 18 consecutive months...

AIM: A decrease of systolic blood pressure in excess of 20 mmHg during haemodialysis treatment (IDD) is common for haemodialysis patients. Intradialytic hypotension (IDH) is symptomatic IDD by definition. Overproduction of nitric oxide (NO) is a possible cause of IDD. Dialysate nitrate and nitrite amount can be used as an indicator of intradialysis NO production. Our aim was to find the predictor of NO production in IDD patients. METHODS: Partial dialysate samples were collected during the whole haemodialysis session and total dialysate nitrate and nitrite amount was measured to assess the association of intradialysis NO production with blood pressure change...

The epidemiology of acute renal failure (ARF) varies between nations and even within the same country because of differences in diagnostic criteria, causes, mode of presentation, and cost of therapy. To determine the factors influencing hemodialysis and outcome of severe ARF in Ilorin, Nigeria, we studied ARF patients on hemodialysis in our center between January 1989 and December 2009. There were 138 (58 males and 80 females) patients with age range between 18 and 69 years and a mean of 29.4 ± 11.9 years...

There is no doubt that arterial hypertension in dialysis patients as well as in patients without renal disease is deleterious for the cardiovascular system. Reducing the pressure values to 130/80 mmHg is what the guidelines suggest. The dialysis setting, however, presents a very different scenario from that of the general population. Dialysis per se is the most powerful of the pharmacological measures in blood pressure control. At the same time, dialysis is an interfering factor in pressure control and can even foster the onset of a perverse vicious circle with, in the same patient, the onset of severe intradialysis hypotension and hypertensive crises in the interdialysis period...

BACKGROUND: In chronic pediatric patients treated with intermittent hemodialysis (IHD), blood volume monitoring (BVM) is commonly used to assess and manage volume status during the dialysis session. Minimal data exists on its use during IHD in critically ill children with acute kidney injury (AKI). In these cases, fluid removal may be limited by hemodynamic instability. METHODS: We present a retrospective study conducted in our pediatric intensive care unit. For eligible patients, demographic data and IHD treatment characteristics were recorded including BVM use, ultrafiltration (UF) volume per session, hypotensive episodes and intradialysis interventions...

Accurate intravascular volume assessment is critical in the treatment of patients who receive chronic hemodialysis (HD) therapy. Clinically assessed dry weight is a poor surrogate of intravascular volume; however, ultrasound assessment of the inferior vena cava (IVC) is an effective tool for volume management. This study sought to determine the feasibility of using operators with limited ultrasound experience to assess IVC dimensions using hand-carried ultrasounds (HCU) in the outpatient clinical setting. The IVC was assessed in 89 consecutive patients at two outpatient clinics before and after HD...

BACKGROUND: The relationship between blood pressure (BP) and mortality in hemodialysis patients has remained controversial. Some studies suggested that a lower pre- or postdialysis BP was associated with excess mortality, while others showed poorer outcome in patients with uncontrolled hypertension. We conducted a multicenter prospective cohort study to evaluate the impact of hemodialysis-associated hypotension on mortality. METHODS: We recruited 1244 patients (685 males; mean age, 60 +/- 13 years) who underwent hemodialysis in 28 units during the two-year study period beginning in December 1999...

AIM: To study causes and sequelae of intradialysis hypotension (IH) in patients with terminal renal failure (TRF). MATERIAL AND METHODS: Forty one patients with TRF on chronic hemodialysis (CH) were divided into two groups. The study group consisted of 24 patients with episodes of IH. Seventeen patients of the control group had no IH. All the patients were examined with assessment of protein-energy deficiency, residual renal function, left-ventricular hypertrophy, diastolic function of the heart...

BACKGROUND: Intradialysis hypotension is a common problem among hemodialysis patients. Some studies have shown that autonomic neuropathy could be a major cause of intradialysis hypotension, whereas others have not. Furthermore, whether there are parallel changes in the autonomic nervous system and somatic nerves remains unclear. METHODS: We investigated the autonomic and peripheral nervous functions of 12 chronic hemodialysis patients who suffered from intradialysis hypotension, and of 12 age- and sex-matched hemodialysis patients who had stable blood pressure during hemodialysis...

Online hemodiafiltration (online HDF) and acetate-free biofiltration (AFB) are 2 innovative renal replacement therapies. Convincing evidence has shown that both techniques are superior to conventional hemodialysis in many aspects. The aim of the present investigation was to compare online HDF and AFB in 12 stable maintenance hemodialysis patients in a prospective, randomized crossover trial. Twelve stable dialysis patients, age 49.7 +/- 11.3 years and on dialysis for 83.5 +/- 76.7 months, were treated prospectively and randomly by either AFB, predilution HDF (pre-HDF), or postdilution HDF (post-HDF) for a total of 36 weeks using exclusively F60S high-flux dialyzers...

We conducted a randomized crossover trial to establish, within patients, whether long-slow hemodialysis (HD) was associated with better blood pressure (BP) control than standard HD. Nine home HD patients, not on antihypertensive drugs, were dialyzed to the same eKt/V(urea) and target weights for 6-8 h (LD) at home and for 3.5-4.5 h (SD) in the dialysis center 3 times weekly in randomized sequence, with each phase lasting 8 weeks. Ambulatory BP, bioimpedance, neurohormones and autonomic function were measured in each phase...

Intradialysis hypotension is a common problem, especially in patients with poor left-ventricular function. We studied 6 patients who were on maintenance hemodialysis with left-ventricular ejection fraction of <40%, whose dialysis sessions were often complicated with severe hypotension (systolic blood pressure <90 mm Hg). Dobutamine infusion during dialysis significantly reduced the number of hypotensive episodes, increased left-ventricular ejection fraction, and decreased the number of emergency admissions to the hospital...

BACKGROUND: Despite technological advances in dialysis equipment, the morbidity and quality of life of uraemic patients undergoing regular haemodialytic treatment are still severely affected by acute intradialytic complications possibly related to the treatment itself. Cardiovascular instability still affects >30% of dialytic sessions and, although its pathogenesis is multifactorial, dialysate sodium concentration (and, consequently, intradialytic sodium removal) is one of the main factors affecting intradialytic hypotension...

Many studies have confirmed our original observation that dialysate T set at about 35 degrees C affords a better hemodynamic protection than the standard dialysate T of 37-38 degrees C. In this review we present some new data on the hemodynamic mechanism of the protective effect of cold dialysis on blood pressure. The study was based on serial assessment of the percent changes occurring during dialysis treatment in estimated stroke volume (aortic blood flow determined by Doppler echocardiography), blood volume (hemoglobinometry), arterial pressure (Dynamap), and heart rate (ECG), from which cardiac output (CO) indexes and total peripheral vascular resistances (TPVR) were derived...

We studied in 13 hemodialysis patients intradialytic variations of blood volume (BV) and cardiac output, by means of non-invasive methods. We found a weak correlation, r 0.2 or less, between BV variations and intradialysis blood pressure variations. The sensitivity of the former in describing the variations of the latter was only 32%. During the 30 min preceeding the hypothensive crisis the percent BV variations did not show any predictive trend. On the contrary, refilling increased as blood pressure dropped and a weak inverse relation (r -0...

Careful investigation of the clinical conditions of patients on maintenance hemodialysis for about 20 years in a single dialysis unit was of great interest for evaluation of the pathological consequences in long-term survivors of insufficient correction of uremia and of the dialysis treatment "per se". We analyzed the outcomes for a cohort of 116 patients who started RDT before 1976 and the clinical conditions of the 24 patients still on RDT in our unit at the end of 1991 (average duration of treatment = 222 +/- 23 months)...

The neurosympathetic responsiveness of two groups of uremics, each group treated for the same mean time by dialysis, categorized as normotensive, mean age 28.3 +/- (SE) 3 years, or dialysis hypotension-prone, mean age 49.6 +/- 5 years, was studied by determining plasma norepinephrine and epinephrine before and after postural activation of the sympathetic reflex arc. The study was performed on an interdialysis day and repeated 20 min before and after a regular dialysis on the following day. Standing caused norepinephrine to rise significantly in both the normotensive and the hypotension-prone groups and to a similar extent as in a control nonuremic group...
