Challenging assumptions to improve wound outcomes
Myth: Wound VAC is only for severe or large wounds
Reality: Wound VAC can be used for a wide range of wounds- acute, chronic, surgical, traumatic, and even smaller wounds.
Myth: Wound VAC causes infection
Reality: When use properly, NPWT reduces bacterial load, removes exudate, and promotes a cleaner wound environment.
Myth: Wound VAC painful for all patients
Reality: Some discomfort can occur especially during dressing changes, but most patients tolerated well.
Myth: Wound VAC replaces all other wound care methods
Reality: It is an adjunct therapy. Proper debridement, infection control, and nutrition are still essential.
Myth: Wound VAC speeds healing in every wound
Reality: It promotes healing (granulation tissue formation, new blood vessels formation)
Myth: Wound VAC can be used on any wound without restriction
Reality: There are contraindications
- Untreated osteomyelitis
- Necrotic tissue with eschar
- Malignancy in the wound
- Patients with bleeding disorder
- Exposed blood vessels, organs or nerves
Myth: Wound VAC is only for hospital use
Reality: Many systems are portable and commonly used in outpatient and home settings
Myth: More suction equals faster healing
Reality: Optimal pressure is evidence- based. Too much suction can damage tissue
Myth: Wound VAC eliminates the need for frequent monitoring
Reality: Wounds will require regular assessment, dressing changes, and monitoring for complications.
Myth: Wound VAC works without addressing nutrition
Reality: Healing still depends heavily on nutrition (protein, vitamins, zinc etc).
