Treatment of chronic leg ulcers with a hydrocolloid dressing.
The effects of a hydrocolloid dressing (Comfeel Ulcus) on the physical environment of chronic leg ulcers in 58 consecutive out-patients were investigated. Patients were subdivided into two groups of which Group 1 included 31 (53.4%) and Group 2, 27 (46.6%) patients. Twenty-three (39.7%) patients healed within 7 weeks (study period) and 49 (84.5%) within 1 year (follow-up period). Aerobic and anaerobic bacterial cultures as well as mycotic cultures were performed from ulcer bases of both groups of patients. In Group 1 a 3 mm punch biopsy was taken from the ulcer margins for histopathological examination. In Group 2 serum levels of iron, zinc, copper and selenium were measured and in these latter patients a mean temperature difference of 2.8 degrees C between the ulcer base and the skin surrounding the ulcer was found. There was no difference in ulcer pH in patients belonging to Group 2, independent of bacterial or fungal contamination. Low serum iron was found in 74.1% and anaemia in 40.7% of the patients in Group 2. No differences in ulcer healing were seen in these patients compared with those without iron-deficiency or anaemia. No differences were seen in serum iron, zinc, copper or selenium levels between good and poor healers. There were 22.2% ulcer relapses in Group 1 within a year of the start of the study, with no relapses in those 15 patients of Group 2 who used specially designed compression stockings.
