- Abstract
Different sampling methods were used to collect samples from ventilator pipes after they were sterilized for selecting an optimal sampling method for the disinfection of ventilator pipes. 200 sets of the ventilator pipes used in clinic were randomly divided into group A and B. The pipes in group A were washed by hand and disinfected by the immersion disinfection method with strongly acidic ionized-water; those in group B were washed with automatic cleaning machine and sterilized with an autoclave. After the disinfection, the samples were collected with a shallow-swabbed, lavage and deep-swabbed, respectively, and the collected samples were sent to the microbiology laboratory for bacterial culture to confirm the disinfection. The results showed that qualified rates of the disinfection with the different sampling methods in group A and B were 98.32% and 100% for shallow-swabbed method, 98.32% and 100% for lavage, and 76.22% and 92.67% for deep-swabbed method, respectively. It is indicated that disinfection effects with the different sampling methods for the disinfection of ventilator pipes should be significantly different and the sampling with deep-swabbed method can objectively reflect the disinfecting effect of the ventilator pipe.
