Wound bed prep

Question 1

Acute wound

Answer 1

progress sequentially through the natural phases of healing in a timely manner

High mitotic activity
Therapeutic levels of inflammatory cytokines
Low levels of proteases
Typically heal less than 21 days

Question 2

chronic wounds

Answer 2

do not progress sequentially through healing
Frequently stuck in an inflammatory phase

low mitotic activity
increase levels of inflammatory cytokines
High levels of proteases
May persist months to years

Question 8

criteria for adequate perfusion

Answer 8

Palpable pulse indicates at least 80 mmHg pressure within the foot

ABI- >0.6 and < 1.2

Audible triphasic, or biphasic sound with Doppler

if ABI is greater than 1.2 perform toe pressure indices > 30-55 mmHg

Venous filling time assessment 5 to 15 seconds

rubor of dependency - pallor is greater than 25 seconds and refilling in less than 30 seconds
