Caring for patients undergoing hemodialysis is very critical because of the disease’s complications. In the context of hemodialysis, the essential duty of nurses is to reduce the inflammation resulting from the vascular access.
This clinical trial was conducted on 101 hemodialysis patients in Montaserie and Imam Reza hospitals, Mashhad, Iran, for one month. Sampling was done by non-probability convenience method. Using random allocation, patients were placed into three groups including those who received a combination of alcohol and betadine to disinfect the vascular access site (n = 37; henceforth, group 1), those who underwent a concurrent application of alcohol after betadine (n = 33; henceforth, group 2), and the control group (n = 31). In group 1, the vascular access site was disinfected with betadine solution and alcohol mixed with a ratio of 2:1 before the dialysis initiated. In group 2, alcohol and betadine were used separately for disinfection. In the control group, the routine method of disinfection was performed using betadine, while antiseptic precautions were taken into account. During 12 sessions in four weeks, the vascular access sites of patients were evaluated for inflammation criteria postulated by the Iranian Nurses Association. Data were analyzed by SPSS16 software (significance level of P < 0.05).
Mean inflammation severity was lower in group 1 than in group 2 (P = 0.039). No significant difference was observed between group 2 and the control group (P = 0.079).
The betadine and alcohol combination can be used in similar studies because this combination is simple, inexpensive, and most importantly, effective to reduce the inflammation of the vascular access site in hemodialysis patients.
