- Phenol and Phenolics
- Alcohols
- Halogens
- Oxidizing Agents
- Surfactants
- Heavy Metals
- Aldehydes
- Gaseous Agents
- Enzymes
- Antimicrobials
What type of antimicrobial chemical is Lysol and Pine-sol an example of? What level of disinfectant is this?
Phenol and Phenolics
intermediate-to low-level
What is an example of the antimicrobial chemical Alcohols?
Rubbing alcohol, ethanol
T/F. Soap is more effective than alcohols in removing bacteria from hands.
False –alcohols are more effective
What is an intermediate-level disinfectants and is bactericidal, fungicidal, and virucidal against enveloped viruses?
Alcohols
What are examples of Halogens?
- chlorine
- bleach
- iodophores (betadine)
What type of antimicrobial chemical is Betadine, an iodophor, an example of?
Halogens
In a surgical setting, they use Betadine and degerm it, what does degerming entail?
scrubbing a surface
What anitmicrobial chemical is Peroxide, such as Hyrdogen peroxide, an example of?
Oxidizing Agents
What level of disinfectant and antiseptics are Oxidizing agents?
High-level
What type of antimicrobial chemical are Peroxides, ozone, and peracetic acid examples of?
Oxidizing agents
T/F. Hydrogen Peroxide should be used for wound care.
False– it is cytotoxic to healthy cells and granulating tissues
What are four things Hydrogen peroxide (an oxidizing agent) be used for?
- disinfecting inanimate objects
- becoming a “peroxide blonde”
- removing blood stains from clothing
- combine with baking soda and vinegar for cleaning
What should be used to clean out wounds?
- Normal Saline
2. Commercial Wound Cleansers–> contain surfactants
Why is saline good to use to clean out wounds?
it is physiologic and will ALWAYS be safe (human body = 0.9% NaCl and Saline is 0.9% NaCl)
will not clean well in dirty, necrotic wounds though
Commercial wound cleaners contain surfactants, what does this help do?
help lift bacteria and cellular debris out of wounds
may help with dirty, necrotic wounds
What type of antimicrobial chemical category are soaps and detergents in?
Surfactants
Soaps are good _____ agents, but NOT ______.
degerming
antimicrobial (do not kill microbs)
What makes antibacterial soap different than regular soap?
have had antimicrobial agents added to them
