Instrumental evaluation of the protective effects of a barrier film on surrounding skin in chronic wounds

Abstract

 Objective. This study investigated the effects of Cavilon® No Sting Barrier Film ([NSBF], 3M Healthcare, St. Paul, Minn) on skin surrounding chronic wounds by means of monitoring transepidermal water loss (TEWL).

Methods: Forty patients were examined; 20 patients had pressure ulcers and the other 20 patients had venous leg ulcers. The patients were divided into 2 groups, the first group (treatment group) was treated with NSBF and the second group (control group) was treated with zinc oxide ointment applied to surrounding skin. TEWL values on surrounding skin were monitored before and after the therapy.

Results: Statistical evaluation showed an overall reduction of 45% in TEWL values in both groups by the conclusion of the study period when compared to baseline values (P < 0.01). The NSBF application was a quick and simple process. Removal of residue was not necessary. An additional benefit is that the skin can be seen through the film.

Conclusion: The study objectively demonstrated that the NSBF can help in the management of the skin surrounding chronic wounds.
