Identify and apply the clean, aseptic, and sterile technique required for common OMS procedures
Prevent (nosocomial) healthcare associated infections
Procedure specific use of a clean, aseptic, or sterile technique reduces or eliminates microbes transferred to patients during OMS procedures
• A clean technique is NOT used in a surgical, invasive procedure
ALL SURGICAL PROCEDURES IN OMS ARE INVASIVE PROCEDURES: invasive oral surgery procedures are classified as a clean-contaminated. See table below.
Definition: Invasive Procedures
The differences are subtle!
• Sterile technique refers to the absence of all pathogens
Remember: DO TOUCH ANYTHING EXCEPT STERILE EQUIPMENT OR ITEMS THAT HAVE A BARRIER ONCE YOU’VE DONNED YOUR GLOVES!
|Pathogen||Survival on Hard Surface|
|Herpes (simplex or zoster)||1 hour (3 days on hand towel)|
|Hepatitis B/C/D||B: 1 week or more|
|Cold & Flu Viruses||24 hours|
|Staphylococcus Aureus (MRSA)||days-weeks|
Remember that asepsis is the reduction of pathogens: be aware of all surfaces that can be contaminated.
If you are organized, you can reduce the number of gloves needed to maintain the chain of asepsis.
It’s easy to get a false sense of asepsis just because you’re wearing gloves.
