Abstract
Objective: to determine if there is a relationship between the volume measured by bioimpedanciometry, the type of peritoneal transport and the incidence of arterial hypertension (AH) in patients on peritoneal dialysis (PD).
Materials and methods: a cross-sectional study was carried out. We included 72 patients in PD at the Hospital de San José, who were measured the volume of body fluid by bioimpedanciometría. The patients were classified according to the characteristics of peritoneal transport, established through the peritoneal equilibrium test (PEP), in high transporters (TA), average (TP) and low transporters (TB). The blood pressure figures were evaluated, classifying the patients into normotensive, hypertensive patients controlled with hypertension and uncontrolled hypertension.
Results: the excess water was 2.98 +/- 2.36 L in TP and 3.631L +/- 1.81 L in TA. In normotensive, hypertensive patients controlled with medication and uncontrolled hypertensive patients, average values of excess water were found 3.16 L +/- 2.56, 2.79 L +/- 2.11 and 3.79 L + / - 2.39 L respectively. A frequency of normotension of 28.1%, controlled hypertension of 56.1% and uncontrolled hypertension of 15.8% was found. in the TP. In the TA these values were 10%, 50% and 40% respectively.
Conclusion: TA tend to a greater excess of fluid than TP and have a higher frequency of uncontrolled HA. This could explain the excess mortality reported in this group. The excess of volume, independent of the transporting state, is related to the presence of HA.
