Abstract: ［Abstract］Objective　To compare the dressing effect between new Mesalt dressing and conventional anti-infective treatment with iodine dressing for surgical infected wound．Methods　From July 2010 to July 2011， 120 patients received dressing for infected wounds in our clinic dressing room were randomly divided into two groups: observation group and control group，60 patients in each group．Patients in observation group received Mesalt dressing，while patients in control group received iodine wet dressing．The amount of wound exudate，wound and surrounding skin conditions，anti-infection and debridement completion time，number of dressing changes and wound healing time completely change of patients in two groups were observed. The data were statistically analyzed by SPSS software．Results　The amount of exudate in infected debridement and granulation phase had statistically significant difference between two groups（P＜0.01）．The repair period also had statistically significant difference between two groups（P＜0.05）．The dressing frequency and healing time had statistically significant difference between two groups（P＜0.01）．Conclusion　Mesalt dressing for infected wounds can effectively shorten the debridement，granulation，the repair period and reduce the frequency of dressing changes，reduce wound healing time，the effect of observation group is significantly better than the control group.
