Brief Summary

The worldwide prevalence of open wounds is estimated to be approximately 200 million per year. Negative Pressure Wound Therapy (NPWT), the application of a controlled vacuum to an open wound cavity, has been clinically demonstrated in developed nations to speed the healing time of open wounds by a factor of two or more, and to aid in complete recovery with less scar tissue. Use of NPWT devices has not been feasible in an limited-resource settings due to cost, bulk, and requirement for consistent electricity. This study aims to follow up prior clinical studies that have established the safety and efficacy of simplified NPWT, by assessing changes in wound closure time and wound contraction rate when simplified NPWT is used in a limited-resource setting.

Outcome Measures

Primary Outcomes (1)

  • Time to Wound Closure

    The effect of simplified negative pressure wound therapy device use on the time to definitive wound closure or time to wound becoming appropriate for discharge for eschar formation.

    5-19 days following application of dressing

Secondary Outcomes (1)

  • Rate of Wound Contraction

    5-19 days following application of dressing

Study Arms (2)

Standard Gauze Dressing

ACTIVE COMPARATOR

Patients with wounds that meet eligibility criteria will be randomized, if randomized to the Standard Gauze Dressing Arm, a saline moistened sterile gauze will be packed into the wound with dry gauze and either tape or other means will be used to secure the dressing. The dressing will be changed daily and measured and photodocumented every 72 hours with the Wound Zoom system.

Other: Standard Gauze Dressing

WiCare NPWT dressing

EXPERIMENTAL

Patients with wounds that meet eligibility criteria will be randomized, if randomized to the WiCare NPWT Dressing Arm, a saline moistened sterile gauze will be packed into the wound and then the WiCare dressing and wound pump will be placed on the wound. The dressing will be changed, measured and photodocumented every 72 hours with the Wound Zoom system.

Device: WiCare NPWT dressing

Interventions

Following consenting of participant, the wound will be photographed with the Wound Zoom imaging system and measured for greatest length, width, and depth. For patients randomized to the control arm, only standard gauze dressings will be applied and changed daily. Wounds with the standard gauze dressings will be photo-documented and measured with the same variables every 72 hours. Wounds and dressing will be evaluated daily for drainage, exudate, presence of infection, and gauze dressings will be changed daily.

Standard Gauze Dressing

Following consenting of participant, the wound will be photographed with the Wound Zoom imaging system and measured for greatest length, width, and depth. For patients randomized to the simplified NPWT arm, the standard gauze dressing will be placed then the the WiCare NPWT dressing will be applied. Wounds and WiCare NPWT device will be evaluated daily for drainage, exudate, presence of infection, drainage in pump, integrity of air tight seal. Wounds will be changed by protocol with photo documentation every 72 hours for a total of 18 days or achievement of primary endpoint.

Eligibility Criteria

Age15 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Patients must be at least 15 years of age,
  • Acute wounds \<21 days from any soft tissue traumatic, surgical, or infectious cause.
  • Wound size must be either
  • a minimum of 25 sq cm in cross dimension with a minimum wound depth of 1 cm at the deepest point or
  • a minimum of 16 sq cm in cross dimension with a minimum depth of 1.5 cm at deepest point.
  • Wounds must have been cleaned and debrided of all debris, foreign body contamination (dirt, grass, bone fragments, other debris), necrotic tissue, and pus
  • Wound should be considered stable (not evoloving) and ready for dressing changes every 72hours.
  • Necrotizing soft tissue infection wounds will only be considered after control of infection through medical and surgical treatment and the wound stable enough for a dressing change every 72 hours.
  • Aamputation stump wounds can be included if all other criteria fulfilled.

You may not qualify if:

  • A wound that would be able to be closed primarily or within 5 days through suture closure, flap rotation or immediate skin graft coverage.
  • A wound greater than or equal to 21 cm in either length or width at the initial measurement.
  • A wound in the perineum: defined by the pubic bone anteriorly and the anus posteriorly.
  • A wound with a visible blood vessel of \>3mm.
  • The presence of known cancer in the wound.
  • Acute burns or burns with skin grafts wound.
  • Latex allergy.
  • Expected mortality within 30 days of admission from co-exisitng medical or surgical condition.
