Effect of Micropower Vacuum Dressing on Promoting Wound Healing in Patients with I-II Diabetic Foot

Abstract

Objective. Discuss the effectiveness and value of micropower vacuum dressing (MVD) in promoting the healing of I-II grades diabetic foot wounds. Methods. Sixty patients diagnosed with diabetic foot ulcers and Wagner grades I-II were selected and randomly divided into the control group and experimental group, with 30 cases in each group. The control group was covered with conventional treatments and petrolatum gauze dressings, and the experimental group was treated with MVD on the basis of conventional reatments. The therapeutic effects of the two groups were observed, including healing rate, ulcer area reduction rate, ulcer healing time, dressing change times, ulcer recurrence rate, adverse events, and so on. Results. The healing rate (100%) of the experimental group was higher than that of the control group (56.7%); the wound reduction rate was higher than that of the control group ( $P<0.05$ ); the healing time, the number of dressing changes, and the 1-month recurrence rate were all low in the control group ( $P<0.05$ ). The incidence of adverse reactions in the experimental group (6.7%) was lower than that in the control group (46.7%) ( $P<0.05$ ). Conclusion. MVD has significant effects in the treatment of I-II grades diabetic foot wounds and has few adverse reactions. It is an effective new method that can promote the growth of granulation tissue and epithelium and promote wound healing.
