Feasibility and Safety in the Management of Fluid Overload in Peritoneal Dialysis Patients Through Sweat Stimulation With the Use of Portable Sauna Bath, Pilot Study

Fluid overload is a common problem in peritoneal dialysis (PD) patients and it is associated with left ventricular hypertrophy and other adverse cardiac consequences. Fluid management is therefore an important aspect in the management of dialysis patient. Despite improvements in dialysis methods and other techniques in these patients, fluid overload persists due to the great limitations of the affected population: physiopathological, economic, educational, social and psychological. The above creates the need for other therapies that lead to the reduction of overload and thus avoid the comorbidity that this entails. The objective of this study is to evaluate the feasibility and safety of the use of diaphoresis achieved through the use of portable sauna baths in peritoneal dialysis patients with fluid overload. The patients are subjected to a period of data collection for 3 days and then use the portable sauna bath 30 minutes a day supervised by the research team during the 6 following days, without interrupting their peritoneal dialysis therapy. We plan to recruit at least 9 patients with PD with fluid overload. Changes in the degree of overhydration are determined by bioimpedance spectroscopy and patient weight at the beginning and end after treatment. Changes in body weight, blood pressure, potassium, urea and creatinine levels, the degree of edema, as well as knowledge about the salt and liquid line were also evaluated. Adverse events will be reported.
