Purpose of the study:The purpose of this study was to evaluate the effect of cool dialysate on itching status of patients with chronic renal failure hemodialysis during hemodialysis. This is an easy method of treatment, without any cost, available, and without complications.
Design: The study was a randomized triple blind controlled clinical trial, done in the before and after treatment method.
Methodology: Population: The study will be done on hemodialysis patients who go to dialysis ward of Imam Reza hospital in Mashhad. After determining patients with pruritus, individuals are selected based on inclusion criteria. Inclusion criteria are history of itching during dialysis, during the last 2 months and lack of skin problems and anemia. Exclusion criteria included acute complications (cardiac, respiratory arrest, Disequilibrium syndrome) and the lack of cold tolerance. Interventions: The study will be done on 30 patients in the intervention group and 30 patients in the control group who had the inclusion criteria and were randomly divided. Blinding will be imposed on patients in both groups and researchers and statistical analyst of this study. For one week, all patients in both groups will get hemodialysis with dialysis solution with standard temperature (37 ° C). Then, for one week, the experimental group will get hemodialysis with cold dialysis solution with temperature (35.5 ° C) and the control group will get hemodialysis with dialysis solution with standard temperature (37 ° C).
We will analyze and record the itch status of patients during hemodialysis with a questionnaire, in both groups, before and after the intervention, and the results of both groups will be analyzed using statistical tests.
