RESUMO
Objective To observe the application effect of the Iodophors hygro-gauze on tracheotomy wound dressing. Methods Fifty patients who underwent tracheotomy with Ⅲ incision, were chosen to be divided into the control group and the observation group with 25 in each group. With saline water cleaning incision and surrounding skin, then disinfection with 0.5% iodophors sanitizers tampon. The observation group applied 0.5% Iodophors hygro-gauze on the wound, the control group used vaseline oil yarn. 24 hours after sample inspection, again samples were sent for bacteria analysis, bacterial colonies number, pathogenic bacteria growth and local situation of wound were observed and analyzed. Results The first results upon disinfection showed that bacterial colonies number, pathogenic bacteria growth between the two groups had no difference. After 24 hours sampling showed that the colony count and pathogenic bacteria growth of the observation group was obviously less than the control group. Local wound infection of the observation group was lighter than the control group. Conclusions 0.5% Iodophors hydro-gauze applied for tracheotomy wound dressing can effectively kill various pathogenic microorganism, prevent secondary infection, and also can prevent and treat wound infection.
