[Chronic hemodialysis: risk factors for intra-dialytic hypotension (IDH)].

Haemodialysis is the most used among the different renal function replacement methods. Although the survival is acceptable the mobility is important; intradialytic hypotension is a main cause of such mobility. In this study which included stable chronic haemodialysis patients, the authors evaluate risk factors for IDH. Advanced age, female sex and autonomic insufficiency are risk factors for IDH. Patients with IDH had more serious ventricular arrhythmias, but a cause-effect relationship was not demonstrated.
