Objective: To investigate efficacy of VSD technology for treating diabetic foot wound.


Methods: Forty cases with diabetic foot at level 2 to 4 were collected from hospital from April 2008 to February 2011. All patients were divided into two groups according to informed consent. Twenty cases in treatment group were given debridement and VSD treatment. Twenty cases in control group were treated with wet-dressing change by professional nurses (having attended wound nursing training). Healing rate, ulcer healing time, days of hospitalization, frequency of dressing change and dressing costs were recorded 3 weeks later.


Results: After 3 weeks, 19 cases cured, and the curative rate was 95%. For 20 cases in treatment group, only 1 case cured, 9 cases were with obvious efficacy, and 10 cases were effective. Chi-square test showed that curative efficacy was obviously better in treatment group than that in control group (yz=32.60, P<0.001), and wound healing time was obviously higher in treatment group than that in control group (P<0.001).Wound healing time and days of hospitalization shortened, and frequency of dressing change reduced in treatment group (P<0.001), but no difference was found in dressing cost (P=0.141, P>0.05).


Conclusion: VSD can shorten wound healing time and treatment course, and reduce frequency of dressing change. It cannot increase treatment costs, and is worth to be popularized.
