Topical treatment of necrotic foot ulcers in diabetic patients: a comparative trial of DuoDerm and MeZinc.

An open randomized controlled study was carried out of 44 diabetic patients with necrotic foot ulcers treated with adhesive zinc oxide tape (MeZinc) or with an adhesive occlusive hydrocolloid dressing (DuoDerm). Fourteen of the 21 patients treated with MeZinc had their necrotic ulcers improved by at least 50% compared to six out of 21 with the hydrocolloid dressing (P less than 0.025). Fifteen patients showed an increase in the area of necrosis during the course of the 5-week study and of these, 10 had been treated with the hydrocolloid dressing.

Adhesive retention dressings are more comfortable than alginate dressings on split-skin-graft donor sites.

Painful split-skin-graft donor sites remain a common problem for patients. We undertook a prospective randomised trial to examine the comparative comfort and ease of care of two different donor-site dressings. One dressing is the alginate Kaltostat, the standard plastic-surgical dressing in the UK and abroad, and the other is the adhesive retention tape Mefix, a novel use of a readily available dressing. We randomised 50 patients requiring split-skin grafts to receive either alginate (Kaltostat) or retention (Mefix) donor-site dressings. Dressings were assessed by interview and questionnaire at 24, 72 h and 2 weeks, and by wound review at 2 weeks. Retention dressings were found to be more comfortable, required less nursing intervention and allowed patients easier mobility with a greater range of daily activities, especially washing, without compromising wound healing. We recommend adhesive retention dressings as cost-effective comfortable dressings, which readily conform to any donor site.

Use of chitosan bandage to prevent fatal infections developing from highly contaminated wounds in mice.

HemCon bandage is an engineered chitosan acetate preparation used as a hemostatic control dressing, and its chemical structure suggests that it should also be antimicrobial. We tested its ability to rapidly kill bacteria in vitro and in mouse models of infected wounds. We used the Gram-negative species Pseudomonas aeruginosa and Proteus mirabilis and the Gram-positive Staphylococcus aureus that had all been stably transduced with the entire bacterial lux operon to allow in vivo bioluminescence imaging. An excisional wound in Balb/c mice was inoculated with 50-250 million cells followed after 30 min by application of HemCon bandage, alginate sponge bandage, silver sulfadiazine cream or no treatment. HemCon was more adhesive to the wound and conformed well to the injury compared to alginate. Animal survival was followed over 15 days with observations of bioluminescence emission and animal activity daily. Chitosan acetate treated mice infected with P. aeruginosa and P. mirabilis all survived while those receiving no treatment, alginate and silver sulfadiazine demonstrated 25-100% mortality. Chitosan acetate was much more effective than other treatments in rapidly reducing bioluminescence in the wound consistent with its rapid bactericidal activity in vitro as well as its light-scattering properties. S. aureus formed only non-lethal localized infections after temporary immunosuppression of the mice but HemCon was again more effective in reducing bioluminescence. The data suggest that chitosan acetate rapidly kills bacteria in the wound before systemic invasion can take place, and is superior to alginate bandage and silver sulfadiazine that may both encourage bacterial growth in the short term.

The effect of a new tissue-adhesive wound dressing on the healing of traumatic abrasions.

BACKGROUND: Octylcyanoacrylate is a new medical-grade adhesive with antimicrobial properties. It forms a thin, flexible, occlusive bandage. OBJECTIVE: To determine the gross and histological effects of the spray bandage when treating abrasions. METHODS: Abrasions were produced on the flanks of 18 albino guinea pigs and randomized to treatment with a control (Biobrane) or octylcyanoacrylate dressing. The wounds were assessed with digital photography using a previously validated method. Histopathological analysis was done on day 14. RESULTS: There were no differences in the mean wound-healing ratios on days 1 (1.25 vs. 1.23, p = 0.61), 7 (1.15 vs. 1.13, p = 0. 14) and 14 (1.03 vs. 1.02, p = 0.63) for tissue adhesive and Biobrane, respectively. There were no differences found on histopathological analysis either. CONCLUSIONS: This external spray bandage was well tolerated and did not show any signs of histotoxicity or adverse wound healing.
