skin antisepsis Flashcards
transient bacteria
- epidermis
- removed by normal mechanical cleansing
a natural disinfectant
- sweat (acidic)
- less in axillary and pubic region bc alkaline
3 goals of surgical skin prep
- remove soil/transient bacteria
- reduce resident bacteria below patho level temporarily w/ least amt of skin irritation
- stop rapid rebound micro growth
6 features of antimicrobial agents
- broad spectrum
- high log reduction capability
- persistency
- nonirritating
- nontoxic
- fast acting even w/ 1st application
7 steps of surgical skin prep
- assessment
- preop cleansing
- preop hair removal
- expose area for prepping
- apply agent
- sponging
- subsequent sponging
hair removal for surgical skin prep
-against the direction of hair growth
epidermis
shedding, stratified squamous epithelium
dermis
collagen elastin, hair follicles, sweat/sebaceous glands, blood/lymph vessels, nerves
resident bacteria
- dermis but can surface to epidermis via sweat and other secretions
- reduction via chemical agents only temporarily
antimicrobial scrubs
-idophors+detergent
antimicrobial paints
only idophor
is shellfish allergy a contraindication for provodone iodine
no
how much area to expose for skin prep?
6-8 inch outward from incision site
direction of vaginal skin prep
- Pubic area to inner thigh both sides
- Perineal area: clit-labia-anus each side
- Vaginal wall
direction of contaminated area skin prep
-contaminated area (stoma first) which may not be the incision site
