Hemodynamic patterns and spectral analysis of heart rate variability during dialysis hypotension.
Intradialytic hypotension, a major source of morbidity during hemodialysis and ultrafiltration, is often accompanied by paradoxical bradycardia. Relatively little is known about the sequential changes in autonomic nervous system activity up to and during the hypotensive episode. Continuous, beat-to-beat measurements of BP and heart rate were made during hemodialysis in patients prone (n = 8) an...
متن کاملMechanism of dialysis-induced hypotension.
Using a hematocrit monitoring system and a Swan-Ganz catheter, the authors investigated the changes in blood volume and hemodynamic parameters before, during, and after dialysis-induced hypotension. When hypotension occurred, the cardiac output dropped sharply, and there were concomitant sudden decreases in the mean pulmonary arterial pressure and the mean right atrial pressure. These are attri...
متن کاملMethylene Blue and Dialysis-Related Hypotension
End stage renal disease (ESRD) affects over 400,000 Americans, and over 8 million have chronic renal insufficiency [1]. Chronic renal insufficiency (CRI) describes a continuum of impaired renal function based on several parameters including glomerular filtration rate and serum creatinine. As renal function deteriorates, the risk of all-cause mortality increases [1]. The most prevalent form of r...
متن کاملPrevention of dialysis hypotension episodes using fuzzy logic control system.
BACKGROUND Automatic systems for stabilizing blood pressure (BP) during dialysis are few and only control those variables indirectly related to BP. Due to complex BP regulation under dynamic dialysis conditions, BP itself appears to be the most consistent input parameter for a device addressed to preventing dialysis hypotension (DH). METHODS An automatic system (ABPS, automatic blood pressure...
متن کاملIs dialysis hypotension caused by an abnormality of venous tone?
The role of peripheral vascular tone in the development of hypotension induced by dialysis was investigated in eight patients undergoing haemodialysis with acetate or bicarbonate buffered fluid. Each patient had two sessions of dialysis with acetate fluid and two with bicarbonate fluid in the order acetate, bicarbonate, bicarbonate, acetate or bicarbonate, acetate, acetate, bicarbonate. Mean ar...
