- decreases incision area from becoming infected with bacteria from GI/biliary tract
When should a sterile field be prepared?
In location it will be used
As close to time of use as possible
What are items with doubtful sterility considered to be?
Contaminated
Ex - break in packaging
A sterile field can have non sterile items in it?
No.
Use only sterile items in sterile field
A sterile field is contaminated when a non sterile item comes in contact with it
Sterile persons touch only sterile items
Where is a sterile field?
Front of sterile gown from chest to level of instrument table/OR bed
From sleeve up to 2inch above elbow
-cuff considered unsterile and need to remain covered by gloves
Movement in the OR around sterile field
Cover during periods of high activity
- repositioning
Limit movement and door opening
Cover if not being used right away
What are edge of sterile packs considered?
Non sterile
What if there is more than one wound class in a surgery?
May need more than one sterile field
Before preparing sterile field?
Surgical attire - change when contaminated - remove at end of shift Hand hygiene Surgical mask Opening supplies
This to check when opening sterile supplies?
Check packaging
Expiration date
Single use item sterility
Chemical indicators of sterilization
Why do rigid containers have filters?
Holes in lid and bottom
