The management of hypotension in dialyzed patients.

Acute hypotension is a frequent hemodialysis complication. This intra-treatment vascular instability is a multifactorial process in which procedure-related and patient-related factors may influence the decrease in plasma volume and the impairment of cardiovascular regulatory mechanisms. Identification of the most susceptible patients and of the various risk factors may contribute to significantly improving cardiovascular stability during dialysis. In some high-risk patients, continuous monitoring of the various parameters can predict the appearance of symptomatic hypotension and help to prevent its onset.
