Aseptic techniques Flashcards
Transmission types
Contact: direct, indirect, droplet. Airborne, vehicle, vector. Vehicle is like indirect, but could be like a contaminated solution or medication.
4 moments of hand hygiene
Before contact with patient or patient environment, before aseptic procedure, after body fluid exposure risk, after patient/patient environment contact.
What to do to prevent exposure to influenza and other droplet transmitted pathogens?
Gloves, gown, eye protection/faceshield, clean your hands
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)
What to do to prevent exposure to TB and other airborne transmitted pathogens?
Just a N95 mask! The patient wears just a normal mask and is in a negative pressure room.
How do you doff (remove) your equipment after seeing a patient with influenza and methicillin resistant S aureus?
Gloves into garbage, clean hands, gown, clean hands, mask, clean hands (outside in). And wash your steth (with hand sani or alcohol wipes)!
Clean phone and pagers!
Yes!
How could you pick up C difficile diarrhea?
Spores, so alcohol doesn’t work.
Alcohol drawbacks
Only works where it touches, flammable, no lasting effect, doesn’t work on certain pathogens.
What is asepsis?
Practice to reduce or eliminate contaminants from entering the operative field in surgery or medicine to prevent infection
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.
Sources of infections
Environment, instruments, patient, surgical team, type of operation, surgical technique
Environment
Dedicated, regulated airflow and temp, cleaned often, limited traffic
Instruments
Autoclaved, radiated, special packaging, stored sterilely
Patient
Wears gowns, shave prep in OR, cleaning solution on area, pre-op antibiotics, superbugs…?
