  • Application of Vacuum-assisted Closure in the Treatment of Venous Ulcer of Lower Extremities

    ObjectiveTo analyze the clinical effect of vacuum-assisted closure in treating venous ulcer. MethodsThirty seven patients including 21 males and 16 females with lower extremity venous ulcer treated in our hospital from January 2013 to January 2014 were included in our study. Based on random number table, the patients were divided into treatment group [n=19, (66.47±6.22) years old] and control group [n=18, (66.39±5.37) years old]. The treatment group received vacuum-assisted closure, while the control group underwent routine moist therapy. Wound healing and visual analogue pain scores were observed. Chi-square test and t-test were used for statistical analysis. ResultsWound healing rate was 84.2% in the treatment group and 55.6% in the control group, and the difference between the two groups was statistically significant (χ2=26.66, P<0.05). Wound healing time was (13.84±3.13) days in the treatment group and (27.35±1.73) days in the control group, and the difference was statistically significant (t=-7.498, P<0.01). Visual analogue pain scores in the treatment group was 3.53±0.51, and in the control group, it was 4.41±0.51, and the difference was statistically significant (t=-5.197, P<0.01). ConclusionVacuum-assisted closure can significantly improve wound healing and alleviate sufferings in the treatment of venous ulcer.
