Week #5: Dressing + Intervention

_ wound healing accelerates process

• Why?

Moist

• Increased epidermal cell migration, autolytic debridement, current injury, protect healthy tissue, prevent infection

What is primary and secondary dressing?

P: in direct contact with wound bed, different permeabilities, may have active ingredients

S: any other dressing placed over primary (ex: for absorbance, security, compression, pressure)

Permeability

_ → _ → _

• Examples

Permeable → Semipermeable → Occlusive

• Loose/fine weave gauzes → Calcium forms → Hydrocolloids

Gauze is --, impregnated gauze carries extra - and - less to skin

What is an alginate?

• Advantage vs disadvantage

Derived from seaweed with Na/Ca salts woven in

• Absorbs exudate, could be mistaken for purulence

Foams for managing moderate -

exudate

What is hydrogel and what is it good for?

Water in gel form, good for rehydration of dry wounds

Semipermeable film advantages!

Secures primary dressing, good visualization, moisture, reduce friction/shear

Hydrocolloid is fully -, can facilitate - -. Yellow/brown malodorous - common with dressing removal and often mistaken for -

Occlusive, autolytic debridement. Exudate, purulence.

Composite dressing have _ characteristics of others. Good for reduction of skin stripping, dressing removal, decrease trauma to wound bed and reduction of pain due to -

Slough

What is a collagen matrix?

Binds to MMPs, which improves growth factor function. Will disintegrate fully

Biologics move - into area, make sure you have a healthy environment - applying

• For hard to heal wounds

Cells, before

What are three common periwound skin products?

Moisturizers, moisture barriers, liquid skin protectants, wound cleansers
