NPWT Quiz

What is the primary mechanism by which NPWT promotes wound healing?

• Hyperbaric oxygen delivery

• Decreasing tissue perfusion

• Mechanical contraction of wound edges

• Inhibition of granulation tissue

The optimal negative pressure used in NPWT for most wounds is:

• -50 mmHg

• -75 mmHg

• -125 mmHg

• -200 mmHg

Which of the following is NOT a component of the NPWT system?

• Sealed wound dressing

• Vacuum pump

• Antiseptic irrigation system

• Drainage tubing

NPWT reduces wound edema by:

• Stimulating platelet aggregation

• Applying interstitial negative pressure

• Activating lymphatic constriction

• Blocking blood vessels

Microdeformation at the cellular level in NPWT helps by:

• Inducing apoptosis

• Promoting capillary thrombosis

• Stimulating fibroblast proliferation

• Blocking cytokines

In NPWT, continuous negative pressure is preferred over intermittent in cases of:

• Grafted wounds

• Infected wounds

• Chronic diabetic ulcers

• Bone exposure

A key contraindication to NPWT is:

• Large area burns

• Clean surgical wounds

• Malignancy in the wound

• Granulating ulcers

Which wound environment is created by NPWT?

• Hyperoxic and dry

• Hypoxic and alkaline

• Moist and hypobaric

• Acidic and dry

Which of the following terms is synonymous with NPWT?

• TENS therapy

• VAC therapy

• MIST therapy

• Pulsatile lavage

NPWT is particularly useful in which of the following orthopaedic scenarios?

• Acute compartment syndrome

• Exposed bone or implant wounds

• Closed fracture wounds

• Osteoporotic vertebral fractures
