BACKGROUND The pathophysiology of chronic hypotension (CH) in uraemia is not elucidated. The possible role of autonomic nervous system dysfunction and adrenoceptor alterations in the pathophysiology of CH in uraemia was evaluated in this study. METHODS Seventeen hypotensive haemodialysis (HD) patients, 17 normotensive HD patients, and 17 control subjects were studied. We evaluated the integrity of the baroreflex arc (Valsalva manoeuvre), the parasympathetic efferent pathway ('deep-breathing… 
Categorization of the hemodynamic response to hemodialysis: The importance of baroreflex sensitivity
TLDR
Impaired resting BRS and recognition of a suboptimal peripheral pressor response, appear to predict those patients most likely to undergo hemodynamic instability and may assist in the pursuit of this elusive goal.
Exaggerated blood pressure response to dynamic exercise despite chronic refractory hypotension: results of a human case study
TLDR
This case highlights the potential therapeutic role of unloaded leg cycling exercise during dialysis session to correct chronic hypotension, allowing patients to have greater tolerance to fluid shift and adds to existing evidence that sympathetic dysfunction is reversible with renal transplant.
Endovascular renal denervation: a novel sympatholytic with relevance to chronic kidney disease
TLDR
Evidence suggests that endovascular renal denervation reduces both afferent and efferent sympathetic nerve activity, which may offer clinical benefit over and above any blood pressure-lowering effect, in patients with resistant hypertension.
Increased Hepato-Splanchnic Vasoconstriction in Diabetics during Regular Hemodialysis
TLDR
In chronic HD-patients hepato-splanchnic blood flow substantially decreases during moderate UF as a result of an active splanchnic vasoconstriction, indicating that diabetic HD-Patients might have an increased risk for bacterial translocation, endotoxemia and systemic inflammation.
Proto-dialytic cardiac function relates to intra-dialytic morbid events.
TLDR
Low CI and high TPRI in the first 30 min of HD are associated with an increased risk of IDME, and the relationship between proto-dialytic cardiac function and IDME in HD patients is investigated.

TLDR
Interdialytic hypertension is highly prevalent and difficult to control among hemodialysis patients and end-expiration IVC diameter is associated with poor control of hypertension in cross-sectional analyses as well as after washout of antihypertensive drugs.

TLDR
Du Cheyron reports on the use of two commercially available technologies to control IDH in hospitalized patients with acute renal failure by controlling hypovolemia and core temperature, a putative culprit in distributive shock during dialysis.
Cardiac response to hemodialysis with different cardiovascular tolerance: Heart rate variability and QT interval analysis
TLDR
The decrease in the LF component of HRV and the QT shortening are coherent with the worse cardiovascular tolerance observed in BD and with the hypothesis of an enhanced production of endogenous nitric oxide.
Rationale for the Use of Blood Volume and Temperature Control Devices during Hemodialysis
TLDR
This review critically discusses the application of blood volume- and temperature-measuring devices with regard to their usefulness in the clinical setting.
Biofeedback Regulation of Ultrafiltration and Dialysate Conductivity for the Prevention of Hypotension during Hemodialysis
TLDR
The use of a biofeedback system to monitor and regulate blood volume during dialysis was helpful in restoring cardiovascular stability in a population of hypotension prone hemodialysis patients and improved hemodynamic stability over the study period.
