Back
Patients on peritoneal dialysis (PD) are usually overhydrated, with the technical difficulty of managing this volume overload, especially in anuric patients. We carried out this work to evaluate whether overhydration and malnutrition of our patients on PD is associated with a higher incidence of complications such as peritonitis, hospitalizations and mortality.
We carried out a retrospective study evaluating the measurement by multifrequency electrical Bioimpedance (BIE) made with Fresenius Medical Care Body Composition Monitor equipment in the patients of our PD service, relating the phase angle (PA) as a marker of malnutrition and overhydration (OH) defined as those patients who present a water overload greater than 2.5% of their body weight at the time of consultation. These two parameters are related to clinical situations such as hospitalizations, presence of diabetes, mortality and incidence of peritonitis, with the rest of the parameters among themselves and with laboratory findings six months before and after the BIE measurement. The results were analyzed with Chi square test.
Conclusions
In our patients, OH was associated with a higher risk of hospitalization and peritonitis. Moreover, it was also observed that these patients were more frequently diabetic, with hypoalbuminemia and PA <4.5 as markers of malnutrition.
