Bacteria-blocking effect of surgical gowns with new material / 中国感染控制杂志

ABSTRACT

Objective To study bacteria-blocking effect of surgical gowns with new material.Methods Semi-quantitative and qualitative testing methods were used to detect bacteria-blocking rates of key sites of surgical gowns(chest and forearm), the detected samples included sample A (composite material, unused), sample B (composite material, after washing 100 times), and sample C (monolayer material, unused).Results In semi-quantitative testing,the average bacteria-blocking rates of three samples were 75.47%, 70.78%, and 73.73% respectively.In qualitative testing,three samples could effectively block the penetration of Staphylococcus aureus under wet condition and Bacillus subtilis var.niger spores under dry condition.Conclusion In semi-quantitative testing, all three kinds of samples had bacteria-blocking effect, and the average bacteria-blocking rate was> 70%;in qualitative testing, three samples all meet requirements of bacteria-blocking effect under wet and dry condition.
