封闭式负压引流术在毁损性手外伤临床治疗中的应用

Objective To evaluate the effect of vacuum sealing drainage(VSD)ON the destroyed hand injuries.Methods From January 2006 to December 2008,forty pafients with destroyed hand injuries (surface of wound)were randomly divided into VSD group(20 cases)and control group(chlorhexidine wet compress)(20 cases)after debridement. The outcomes were retrospectively analysed by pain score,swelling score,bacterial positive rate and necrotic tissue.Results Three days after treatment,the pain score of VSD group was(2.62±1.54)degree,and that of control group was(3.39±1.64)degree.There wag significant difference between the two groups(P＜0.01).The swelling score of VSD group was(1.51±0.25)degree which was different from control group(2.29±1.26)degree(P＜0.05).The bacterial positive rate of control group was 20%(4/20),but that of VSD group was 5%(1/20).There was significant difference between the two groups(P＜0.05).The VSD group had no necrotic tissue occurrence,but the control group had 2 cases,one of which had serious necrosis and had escapology.Conclusion VSD Can inhibit bacterial infection,ease pain,exempt changing dressings and stimulate growing of granulation tissue also can maintain a good environment for tissue transplantation later.So VSD combining with tissue transplantation is an ideal therapy in destroyed hand injuries.
