The principles of asepsis must be applied to break the cycle of infection and its spread

The condition in which pathogens are absent or controlled

In medical settings – Asepsis can break the COI by preventing the transmission of pathogens

(1) Housekeeping standards reduces the number of pathogens present

(2) Government guidelines protect against diseases

(3) Educating patients

MEDICAL SURGICAL

Clean technique

Maintaining cleanliness prevent the spread of microorganisms

Ensure there are as few microorganisms in the medical environment as possible

Sterile technique

Depends on a completely sterile environment that eliminates all microorganisms

(1) Office Procedures• No eating or

drinking” policy (2) Asepsis During

Medical Assistant Procedures• Prevention of cross-

contamination (3) Hand washing

• Most important aseptic procedure*

(4) Avoid touching your mouth or face

(5) Stay at home if you have a fever

Surgical asepsis takes medical asepsis to another level

Strict set order of procedures

An object or area is considered either sterile or not sterile

(1) Sterile scrub brush is used instead of a nailbrush

(2) Both hands and forearms are washed

(3) Hands kept above elbows

(4) Sterile towels are used instead of paper towels

(5) Sterile gloves are put on immediately after hands are dried

(1) Prepare the area

(2) Keep instruments sterile

(3) Avoid touching instruments that are not sterile

(4) Post-procedure, continue to use aseptic techniques

(5) place any disposable instruments into the bio-hazardous waste container

Sterile Field: Review

An area free of microorganisms that will be used as a work area during a surgical procedure

A sterile field is considered to become contaminated and must be redone when…• An unsterile item touches the field• Some one reaches across the field• The field becomes wet

Prepare a large basin with hot, soapy water and separate sharps from non-sharps

Carefully place instruments in the detergent solution to soak

Scrub each item with a plastic scrub brush ensuring to remove any visible signs of contamination

Sanitization Continued Rinse each piece of equipment under hot

running water ensuring that all soap is removed

Place each instrument on a clean paper towel, rolling it to make sure it dries thoroughly

Wipe down the area with damp towel and use a new paper towel to ensure that the area is dry

Only disinfect instruments that have come into contact with blood

Prepare a small basin with an alcohol disinfectant unit ensuring that the disinfectant reaches every surface of the instruments

Disinfection Continued Use sterile transfer forceps to remove

each instrument and place them on a clean paper towel, patting it to make sure it dries thoroughly

Wipe down the area with bleach and a paper towel and ensure that the area is dry

Prepare sterile porous paper and place each instrument into the middle using forceps

Do not allow instruments to touch each other

Wrap instruments snug – close package with sterile tape Procedure 2-1 & 2-4 on pages 33 & 34

Sterilization Continued Label package with the date, your

name, and name of instruments inside

Instruments are placed in autoclave (121°C – 132°C)

Remove with sterile transfer forceps and oven mitts and store sterile instruments in the same ‘sterile’ location
