To demonstrate the efficacy of a highly hydrophilic polyurethane foam dressing in the treatment of diabetic ulcers.
Diabetic foot ulcers often pose a difficult treatment problem. Polyurethane foam dressings have been used worldwide to accelerate wound healing, but only a few clinical studies demonstrate the effect of foam dressing on the healing of diabetic ulcers.
Medical records of 1342 patients with diabetic ulcers who were admitted and treated at the authors’ institution were reviewed. A total of 208 patients met the study’s inclusion criteria. Of these 208 patients, 137 were treated with a highly hydrophilic polyurethane foam dressing, and 71 were treated with saline gauze (control group). Except for the application of polyurethane foam dressing, the treatment method was identical for patients in both groups. The wound healing outcomes of the 2 groups were compared.
Complete wound healing occurred in 87 patients (63.5%) in the polyurethane foam dressing group and in 28 patients (39.4%) in the control group within 12 weeks (P < .05, X2 test). The mean percentage of wound area reduction in both groups was statistically significant (P < .05, Mann-Whitney U test). The mean time required for complete closure in patients who achieved complete healing within 12 weeks was 6.2 (SD, 3.4) weeks and 7.3 (SD, 2.6) weeks in the polyurethane foam dressing and control groups, respectively (P < .05, Mann-Whitney U test).
These results indicate that the highly hydrophilic polyurethane foam dressing may provide an effective treatment strategy for diabetic foot ulcers.
