Clinical application of improved vacuum sealing drainage on diabetic foot ulcers

Objective： To investigate the effect of improved vacuum sealing drainage （VSD） on the wound healing of open wounds of diabetic foot. Methods： Forty patients with diabetic foot ulcers wounds were divided randomly into control group and treatment group. Patients in control group were treated with routine VSD, while patients in treatment group were treated with improved VSD, in which irrigation with 500 ml of nitrofural and application of epithelial growth factor 30 ml for 30 minutes every day via an inserted suction pipe. The rate of wound healing, growth of granulation tissue, rate of suction pipe blockage 10 days after VSD treatment, as well as the time and expenses of patient in hospital was recorded. Results： There were no suction pipe blockage in treatment group but the rate was 15.0% in the control group （P〈0. 05）. The rate of wound healing [（35.3±4. 4）%] and score of granulation tissue growth （2.9±0. 8） in treatment group were higher than those in control group [-（20.4 ± 3.9）% and 2.1 ± 0. 5, P〈0. 05], while the time and expenses of patient in hospital [-（48. 6±4. 6）days, （8. 7±1.8） × 10^4 yuan] were significantly lower than those in control [（64.6±5.5）days, （10. 0±2. 1） ）〈 10^4 yuan, both P〈0. 05]. Conclusions： Improved VSD can effectively stimulate the growth of granulation tissue and healing of wounds, reduce the expenditure of patients. It is an ideal method to repair diabetic ulcers.
