Control of Microbial Growth - 3 Flashcards
Form covalent crosslinks
Some of the most effective antimicrobials
Aldehyde
Formalin as 37% aqueous solutions
For preserving specimens and inactivating viruses and bacteria
Also used in mortuaries
Formaldehyde Gas
Less irritating than formaldehyde and more effective
One of the few chemical disinfectants that is a sterilizing agent
Glutaraldehyde
A 2% solution of ___ is:
Bactericidal, tuberculocidal, viricidal in 10 minutes
Commonly used to disinfect hospital equipment
glutaraldehyde
Requires exposure of 4-8 hours
Toxic and explosive in pure form
Used to sterilize mattresses and large equipment
Ethylene Oxide
Used as an antiseptic
Not good for open wounds
Best for inanimate objects
Also known as “agua oxinada”
Hydrogen Peroxide
Used in acne medications
Benzoyl Peroxide
such as hydrogen peroxide and peracetic acid, are commonly used for disinfecting in various settings
Peroxygens (Oxidizing Agents)
also known as peroxyacetic acid or PAA, is an organic chemical compound used in numerous applications, including chemical disinfectant in healthcare, sanitizer in the food industry, and disinfectant during water treatment
Peracetic Acid
Inflammation of the IV site
Need to remove IV with doctor’s orders
Phlebitis
- Places that need to use aseptic techniques
Work surfaces should be cleaned
Media and instruments should be sterile
Used cultures must be properly disposed of
