The use of collagen film (Cutycol) as a dressing for donor areas in split skin grafting.

In this investigation sterile collagen film has been used as a dressing for 55 donor areas. The two aims of our study were to find out whether this film could be used as a dressing and whether the film which was applied at the time of surgery could be used as the only dressing before complete healing was achieved. The results were good in 56% of the cases and fair in 20%. It was noted that local pre-treatment with epinephrine gave better results. If only small or medium sized donor areas were included the results were even better. This is probably because the film in larger donor areas could slip away leaving the donor site more or less exposed. The results are encouraging in two important aspects: The donor sites were not painful and the nursing staff could reduce or eliminate time-consuming work with frequent dressings.

Comparative study of four wound dressings on epithelization of partial-thickness wounds in pigs.

Sixteen shallow wounds were inflicted in each of five Yorkshire white female piglets, 18-20 kg body weight, by a 2-cm diameter, fast-rotating abrasive disc. The injury is similar to a second-degree burn. The wounds were dressed with one of four dressings: Duoderm (Squibb), Op-Site (Smith & Nephew) [corrected], and collagen sponge, covered with either occlusive or semiocclusive polyurethane film (Datascope Corp.). The last two dressings were moistened with saline before application. The rate of epithelization by planimetric quantitation after 3 to 5 days was the same regardless of the dressing used, although the epithelium layer was thicker in wounds treated with Duoderm. Wounds dressed by either of the collagen sponge materials showed a better appearance when visually scored. Wounds dressed with Duoderm or Op-Site were often macerated; Duoderm's paste-like material remained on the wound and was difficult to remove without inflicting discomfort to the patient. Duoderm, and also Op-Site, adhered much more strongly to the intact skin than either type of collagen sponge dressing.

A comparative study of glycerinized and lyophilized porcine skin in dressings for third-degree burns.

A comparative study of local treatment with lyophilized and glycerinized porcine skin was performed on 100 patients with third-degree burns. We compared the efficiency, simplicity, and cost of preparation of dehydrated, sterile porcine skin for ready use in temporary dressings for burn victims. We conclude that this is a simple, efficient, and safe method, which, because of its low cost, will permit greater use of porcine skin as a temporary substitute in dressings for third-degree burns.
