A study to compare a new self-adherent soft silicone dressing with a self-adherent polymer dressing in stage II pressure ulcers

Abstract

Pressure ulcers are common among elderly nursing home residents. To be effective in managing these wounds, a dressing should maintain a moist environment, facilitate healing, absorb exudate, remain in place for a number of days, and prevent trauma to the surrounding skin. An 8-week, open, randomized, multicenter, controlled study was conducted to compare the effects of a new self-adherent soft silicone dressing and a self-adherent hydropolymer dressing on Stage II pressure ulcers. Thirty-eight (38) residents participated in the study. Eighteen residents (mean age 83.8 years, range 74.9 to 95.1 years) were randomized to wound management with a soft silicone dressing, and the ulcers of 20 residents (mean age 82.5 years, range 66.4 to 91.9 years) were managed with a hydropolymer dressing. Wound healing, wound and surrounding skin characteristics, and ease of dressing removal were measured and documented. During the study, eight (44%) ulcers in the soft silicone group and 10 (50%) in the hydropolymer dressing group healed. Both dressings were changed approximately once a week and no differences in signs of inflammation, amount of exudate and odor, or incidence of leakage were observed. Damage to the surrounding skin, maceration, and dressing removal difficulties were less common with the soft silicone dressing. Differences in tissue damage between the two dressings were significant during weeks 1, 2, and 3 (P < 0.05). Studies with a larger sample size are needed to confirm these findings.
