[Postprandial blood pressure drop in hemodialysis: myth or reality?]

The meal is a friendly moment of the sessions of dialysis, appreciated by most of the dialysed persons. However the empirical observation allows to notice that certain dialysed persons, present drops of arterial pressure after taking the meal. Where from the questioning: except factors inherent to the dialysis, has the meal a particular incidence on the blood pressure in the course of session? Numerous studies were realized since 1983 on the low blood pressure comment prandiale at the old person, very few studies are available on the low blood pressure comment prandiale in the course of session of hemodialysis, and sometimes little convincing. A comparative method on 2 sessions, one with meal and one without meal, every patient being its own witness, was used. The tool of evaluation consists of a railing resuming variables retained for the study. In view of the study carried out further to this questioning, the hypothesis of departure does not come true: we cannot demonstrate of significant link between meal and arterial pressure drop. However the number restricted by patients (fifty) include in the study, does not allow us to end in favour of the myth, it is necessary for it to pursue the study to obtain the same data with a much more important population.
