W3, Ch 5 Controlling Microbial Growth

Who is considered father of modern surgery?

Joseph Lister

What did Joseph Lister do?

Provided evidence to support the Germ Theory of Disease (that diseases are caused by microbes), developed safety guidelines for surgery and wound treatment

What safety guidelines for surgery and wound treatment did Joseph Lister develop?

Sterilized equipment before use, kept clean operating rooms, antiseptic wound dressing (keeping microbial agents out of wound), hand washing and clean gloves

True/False: Joseph Lister saved more lives than all wars in the 19th century sacrificed

True

What was named after Joseph Lister?

Listerine

What are 3 ways to control microbial growth?

Disinfectants, antiseptics, sterilization

How are disinfectants used?

Applied to surfaces to kill life

How are antiseptics used?

Used to clean skin or other body surfaces as antiseptics are harmful to microbes but not us

What is sterilization?

Destruction or removal of all microbes from a product, and is more intense than disinfection

True/False: Disinfection is more intense than sterilization

False; sterilization is more intense than disinfection

What is an example of a disinfectant?

Bleach, hard-core cleaning products

True/False: Your home compared to the hospital require different levels of microbial control

True; your home does not need to be free of microbes whereas in hospital the spread of pathogenic microbes must be prevented

Does your home have to be free of microbes?

No, your home does not need to be free of microbes (it is probably bad to keep your home too clean)

What is main goal of hospitals concerning microbial control?

To prevent spread of pathogenic microbes (sterilization is high priority here)

What are physical methods of sterilization?

Heat sterilization (boiling microbes), moist heat sterilization, dry heat sterilization, filtration, irradiation, sound (sonic) waves, pressure, sunlight (UV rays), autoclave

True/False: One physical method of sterilization will kill all microbes because its sterilization

False; one method of sterilization is never enough; you always want to treat with more than one method of sterilization to protect patients

How many methods of sterilization should be used to protect patients?

More than one method of sterilization as one method of sterilization is never enough
