摘要

Abstract

Objective

To analyze the barrier function and bacterial penetration of different medical packaging materials in surgical instruments in order to reduce the risk of infection.

Methods

From January to December 2020

the clean operating room of the Second Affiliated Hospital of Fujian Medical University used cotton cloth medical packaging and new reusable long fiber polyester cloth as the research objects. The bacteria penetration experiment (Bacillus subtilis) was conducted under dry and wet conditions respectively

and the impermeability of the two types of medical packaging materials was compared.

Results

There were bacteria growth on the cotton cloth culture medium plate

and the test bacteria penetrated the sample piece; no bacteria grew on the long fiber polyester cloth culture medium plate

indicating that the test bacteria could not penetrate the sample. Under dry conditions

the total bacterial count of cotton cloth was significantly higher than that of long fiber polyester cloth

and the water permeability was higher. The difference was statistically significant (

0.01).

Conclusion

Long fiber polyester cloth has strong barrier function in both dry and wet conditions

low bacterial penetration

high water permeability

and can be used repeatedly.
