Part 1-A research study was conducted to examine the thermal disinfection process of respiratory care products that were contaminated in a laboratory-controlled environment with American Type Culture Collection (ATCC) Pseudomonas aeruginosa. After thermal disinfection, the products were packed in a barrier system designed for disinfected instrumentation and stored under controlled conditions of humidity and temperature. After 70 days, no evidence of contamination was found following the thermal disinfection process and barrier system storage.
Part 2-A descriptive comparative study on hand hygiene at a tertiary private hospital in Brazil will be discussed. Microbiological samples were collected from the hands of 54 surgeons after hand washing to determine the base microbial flora count and after surgical antisepsis to identify the immediate reduction in microbial count. Findings suggest that there is a large reduction in bacterial count after surgical hand antisepsis when the recommended technique is followed.

Learning Objectives:

• Describe how a technique was performed for more than 180 seconds didn't occur with shorter antisepsis times.
• Discuss how the Chi-Square test showed that there was no significant negative association between the time spent performing the procedure and the category of reduction in microbial count.
