COMPARISON OF EFFICACY OF TWO DISINFECTION METHODS IN DISINFECTION DURING DEBRIDEMENT OF OPEN FRACTURE WOUND

Objective To know the efficacy of composite lysozyme disinfectant in disinfection of open fracture wound and to explore the role of the disinfectant in decrease in infection rate of the wound.Methods Cotton swab wiping sampling,bacterial examination and comparison of rate of wound infection were used to carry out observation of clinical cases.Results There were bacterial contamination to various degrees on open fracture wound.The total bacterial count before debridement and disinfection was 216-226 cfu/swab,with no difference between experiment group and control group(using conventional disinfectants).After debridement and disinfection with the composite lysozyme disinfectant in the experiment group,the bacterial count on the wound decreased from 216 cfu/swab before debridement to 23 cfu/swab after debridement,while in control group,the total bacterial count on the wound decreased from 226 cfu/swab before debridement to 52 cfu/swab after debridement.The wound infection rate in experiment group was significantly lower than that in the control group.Conclusions The efficacy of debridement and disinfection method used in experiment group was significantly better than that in control group and the wound infection rate in experiment group was significantly lower than that in control group.The composite lysozyme disinfectant can effectively decrease the infection rate of open fracture wound.
