WEB WOC SEMINARS QUIZ PRACTICE
QUESTIONS AND DETAILED SOLUTIONS
◉ biosurgical debridement.
Answer: a type of non-instrumental debridement using medical
grade maggots to liquify necrotic tissue through proteolytic enzymes
◉ disadvantages of biosurgical debridement.
Answer: distasteful to most patients/caregivers, bleeding, pain,
crawling sensation
◉ contraindications or biosurgical debridement.
Answer: poorly perfused wounds, exposed blood vessels, necrotic
bones, limb-threatening infections
◉ mechanical debridement by wet-to-dry dressing.
Answer: a type of non-instrumental debridement done by using
damp gauze in the wound bed that is allowed to dry out to trap
tissue which is then pulled off during dressing changes
◉ benefits of mechanical debridement by wet-to-dry dressing.
Answer: cheap, dressing change is easy to perform, use in heavily
necrotic or infected wounds without granulation tissue
,◉ disadvantages of mechanical debridement by wet-to-dry dressing.
Answer: painful, non-selective (will pull off healing tissue with
necrotic tissue), time consuming (multiple dressing changes daily
for weeks)
◉ contraindications of mechanical debridement by wet-to-dry
dressing.
Answer: clean granulation wounds
◉ mechanical debridement by irrigation/pulsatile lavage.
Answer: a type of non-instrumental debridement using fluid and
pressure to remove surface debris and bacteria form the wound
base without damaging healthy tissue
◉ benefits of mechanical debridement by irrigation/pulsatile lavage.
Answer: wound cleansing
◉ disadvantages of mechanical debridement by irrigation/pulsatile
lavage.
Answer: potential for splash contamination - wear PPE!
◉ goal PSI for pulsatile lavage.
, Answer: 4-15 psi
◉ mechanical debridement by ultrasonic mist.
Answer: a type of non-instrumental debridement using low-
frequency ultrasonic device to produce acoustic energy that has
mechanical and thermal effects which degrade fibrin and remove
biofilm
◉ benefits of mechanical debridement by ultrasonic mist.
Answer: painless, wound cleansing, biofilm reduction, stimulates
cells to accelerate the healing process
◉ disadvantages of mechanical debridement by ultrasonic mist.
Answer: costly, time consuming, inconclusive research
◉ conservative sharp wound debridement.
Answer: a type of instrumental debridement using sharp
instruments to remove frank, devitalized tissue without causing
bleeding
◉ surgical sharp debridement.
Answer: a type of instrumental debridement using a surgical
instruments to aggressively remove necrotic (and sometimes non-
necrotic to open up wound edges) tissue, causes bleeding
