Abstract:
Objective:To compare the skin disinfection effect in different marking methods.Methods:From June 2015 to August 2018, samples of 200 healthy volunteers were collected in the operating room of a hospital. Using self-matching design, a blank control area A was set up in the upper abdomen of every volunteer, and sterile markers were used to mark areas B, C, D and E. Areas B and C were directly marked on the abdominal skin (solid line of area B, dashed line of area C) , and areas D and E were marked after the skin was disinfected first (solid line of area D, dashed line of area E) . After disinfection, specimens were collected in areas A, B, C, D, and E for bacterial culture and the disinfection effect was monitored.Results:A total of 1 000 samples were collected from 200 healthy volunteers. Among them, 39 bacterial cultures were positive and the number of colonies detected in the positive samples was 1 to 6 cfu/cm 2. The positive rate of skin bacterial culture in the marked area of solid line was higher than that in marked area of dashed line. The differences in the positive rates of bacterial culture in different areas were statistically significant ( Q=51.87, P< 0.01) . Further pairwise comparison showed that the differences between the areas B and C that were first drawn lines and then disinfected and area A were statistically significant (χ 2=20.05, 9.09, P< 0.05) . However, there was no statistically significant difference between areas D and E that were first disinfected and then drawn lines and area A ( P>0.05) . The detection rate of bacteria in area B was higher than that in area C, and the difference was statistically significant (χ 2=7.97, P<0.05) . The detection rate of bacteria in area D was higher than that in area E, but the difference was not statistically significant ( P> 0.05) . Conclusions:Marking and disinfecting the skin at the surgical site will have an effect on the skin disinfection effect. It is recommended that the skin at the surgical site be disinfected first and then marked, and the method of dashed line marking should be adopted.
