Gloves, gown, eye protection/faceshield, clean your hands

4

What to do to prevent exposure to bloody diarrhea and other contact transmitted pathogens?

Gown and gloves and clean hands, and environmental decontamination! (surfaces and equipment)

10

What is asepsis?

Practice to reduce or eliminate contaminants from entering the operative field in surgery or medicine to prevent infection

11

Why difficult to do asepsis?

Can’t see contaminants. We are biological organisms. We are forgetful and make mistakes. We don’t create all cases equally.

12

Sources of infections

Environment, instruments, patient, surgical team, type of operation, surgical technique

13

Environment

Dedicated, regulated airflow and temp, cleaned often, limited traffic

14

Instruments

Autoclaved, radiated, special packaging, stored sterilely

15

Patient

Wears gowns, shave prep in OR, cleaning solution on area, pre-op antibiotics, superbugs…?

16

Surgical team

Equipment (leave scrubs in the hospital!), antiseptic scrub, what what you touch, includes everyone in the OR.
