Gauze versus solid skin barrier for tracheostomy care: a crossover randomized clinical trial.

Purpose: The aim of this study was to compare gauze and a solid pectin-based skin barrier to evaluate clinical outcomes and cost-effectiveness of care for tracheostomy wounds.

Methods: A randomized clinical trial with crossover design was conducted to compare gauze to a solid skin barrier for management of patients with tracheostomies. The main study outcomes were skin integrity, dressing change frequency, time required for dressing changes, product costs, and nurses' satisfaction.

Setting And Subjects: A convenience sample was recruited from 2 medical centers in Taiwan. Using permuted block randomization, patients undergoing tracheostomy were randomly allocated to 1 of 2 groups. One group received tracheostomy care with gauze for the first 6 days and a solid pectin-based skin barrier for the following 6 days. This regimen was reversed in the second group.

Results: Skin integrity was significantly better among patients managed with a solid skin barrier as compared to management with gauze (Z=-2.75, P= .006). No significant differences in dressing change frequency, time required for dressing changes, or product costs between the 2 groups were found. Nurses' satisfaction was significantly higher for the solid skin barrier as compared to gauze (Z=-2.31, P= .021, for group 1, and T=-1.97, P= .048, for group 2).

Conclusions: The use of a solid skin barrier for tracheostomy care was associated with lower occurrences of impaired skin integrity and higher satisfaction among nurses when compared to gauze.
