Comparison of Hydrocolloid Dressings and Silver Nanoparticles in Treatment of Pressure Ulcers in Patients with Spinal Cord Injuries: A Randomized Clinical Trial.

There are numerous dressings used to treat pressure ulcers (PUs), depending on their advantages to achieve optimum patient outcomes. This study aimed to compare hydrocolloid dressings and silver nanoparticles in treating PUs among patients with spinal cord injury (SCI). This randomized clinical trial was conducted on 70 patients with SCI in Iran. Participants were randomly divided into two equal groups (n=35) receiving silver nanoparticle dressing and hydrocolloid dressing, respectively. The groups were evaluated in four assessment periods using the Bates-Jensen Wound Assessment Tool (BWAT). Data analysis was performed using SPSS software version 13, repeated measures ANOVA, non-parametric tests, and chi-square. Chi-square test was used to investigate the difference between the scores before the intervention, the results of which were not statistically significant. In repetitive measurements, the results of the analysis of variance showed that the average assessment score in both groups decreased and both dressings were effective in the treatment process. Although PU improvement status in the group that received silver nanoparticles was better, between-group analysis of variance did not show any statistically significant difference between the two groups. Our results indicated that silver nanoparticles and hydrocolloid dressings can be used interchangeably in the treatment of PUs.
