Article
In patients with arteriovenous fistulas, assessment of pH and oxygen status during hemodialysis (HD) using the extracorporeal dialysis arterial blood line is widely used both in daily routine and in most studies investigating hypoxia during HD. We designed this study to evaluate whether results of blood gas samples drawn from the extracorporeal art...
Article
Eleven patients with chronic renal failure who were being treated with haemodialysis three times a week were monitored for a total of 34 haemodialysis sessions. Erythrocyte 2,3-biphosphoglycerate (2,3-BPG) concentration was analysed immediately before initiation of bicarbonate haemodialysis and 1 h afterwards. The 2,3-BPG concentration was expresse...
Article
Hypoxia occurs frequently during routine hemodialysis (HD). In this study the effect of dialysate temperature on arterial blood gas parameters was investigated. Ten stable HD patients (2 smokers) were dialyzed for 240 min with each of three different dialysate temperatures: 36.5 degrees C (normal temperature HD; NHD), 38.5 degrees C (warm HD; WHD)...
Article
Continuous monitoring of blood oxygen tension was carried out during 45 hemodialyses sessions. The oxygen tension curves displayed different appearances. Some curves presented with a periodicity like sinus curves (type 1), while others (type 2) fluctuated with other appearances, or displayed straight lines. Blood pressure variations during dialysis...
Article
Hypoxia during haemodialysis, mainly acetate, has been reported several times. In our study we have monitored oxygen status during 258 bicarbonate haemodialyses. A significant drop below 80 mmHg in mean oxygen tension occurred. Mean oxygen saturation reflected this drop but did not reach levels below 90%. The mean oxygen concentration was on the wh...
Article
In 69 patients on chronic haemodialysis, blood sampled randomly during dialysis was analyzed for carboxyhaemoglobin (COHb). The median value was 1.40% (range 0.9-2.3) in non-smoking patients and (1.4-7.5) in smokers. In non-smokers treated with erythropoietin (EPO) correlation was found between COHb and the weekly EPO dose (r = 0.57, p = 0.007). In...

The aim of the study was to perform peritoneal equilibration test (PET) in predialysis patients, and compared to PET results in patients on chronic peritoneal dialysis (PD). Two groups of patients were enrolled in the study. Group 1: eleven uremic patients who had never been subjected to PD, and group 2: fourteen patients on maintenance PD. The PET...
Article
Blood pressure stability is better during cold hemodialysis (HD). This has mainly been attributed to a more pronounced sympathetic activation during cold than during warm HD. The authors studied the effect of dialysate temperature on vasoactive peptides, noradrenaline (NA), and renin (PRA). Ten hemodynamically stable patients were dialyzed for 240...
Article
The high plasma levels of the vasodilating hormone atrial natriuretic peptide (alpha-ANP), observed in patients with chronic renal failure, decrease substantially during hemodialysis (HD), probably owing to volume reduction. Cardiovascular stability is better maintained by the use of cold dialysate although underlying mechanisms are unknown. In ord...
Article
Since Johnson et al reported the occurrence of hypoxia during hemodialysis in 1971,1 many investigations have confirmed occurrence of hypoxia during hemodialysis (HD) in a large number of clinical settings. Much conflicting data and confusion have arisen from these reports. Further difficulty stems from the great inconsistency and inaccuracy of ter...
Article
Antibodies to hepatitis C virus (anti-HCV) were determined in an unselected group of 340 patients with chronic renal failure treated with maintenance dialysis. A second generation hepatitis C virus (HCV) enzyme-linked immunosorbent assay (ELISA) was used and confirmation made by a second generation recombinant immunoblot assay (RIBA). Sixteen patie...
