Skin Asepsis Flashcards
(35 cards)
What is an SSI?
An infection that occurs after surgery in the part if the body where surgery took place
Goal of skin asepsis?
Reduce the patients risk of developing an SSI by removing soil and transient microorganisms at the surgical site and surrounding area
Skin prep is done to?
Decrease resident microbial count as much as possible
In shortest amount of time
With least amount of tissue irritation
To prevent rapid rebound growth of microbes
Skin and layers?
First line of defense against infection
- contains resident and transient flora
Break in skin = portal of entry
Epidermis = outer most Dermis = middle layer Subcu = inner layer
3 types of SSI’s?
Superficial incisional - epidermis/dermis/subcu
Deep incisional - fascial and muscle layers
Organ space
Impact of SSI’s?
Cause of morbidity and mortality
Leading cause of readmission following sx
Impacts patients
- loss of wages/employment
- loss of function
- chronic health problems
Impacts facility
- loss of OR time
- increased readmission
Risk factors for SSI?
Increased age Smoking Diabetes Malnutrition Poor understanding
Emergency surgery
Degree of contamination on surgical site
Prevention of SSI?
Patient education Shower night before sx Intra op surgical skin prep Adherence to strict aseptic principles Careful observation of sterile technique
Pre op skin considerations?
Bathing decreses microbial skin contamination Allergies Skin condition at surgical site Jewelry Surgical site marking Hair removal Nutritional status
Is there a correlation between seafood and iodine allergy?
Research has shown no correlation
It is safe to use povidone iodine
Desired features of skin antiseptic products?
Applied quickly Not irritating to skin Not inactivated by other chemicals/body fluids Single use Coloured to increase visibility of prep FDA category 1
What are FDA category 1 requirements?
Fast acting
Broad spectrum
Persistent
Decrease microbial counts

Who does skin prep and why?
Applied by circulating nurse to prevent contamination
Use sterile gloves and supplies
Applying prep to site?
