Brief Summary:
Subjects requiring skin grafting due to burns, trauma, or chronic venous ulcers with split thickness donor sites expected to be between 20 and 200 square cm will be consecutively screened for study eligibility. This study is a prospective, randomized, controlled trial evaluating effect of MIST Therapy on the healing of split thickness skin graft donor sites compared to standard care. Subjects meeting all eligibility criteria and providing appropriate written informed consent will be enrolled for study participation.

Condition or disease Intervention/treatment Phase
Burns Trauma Venous Ulcers Device: MIST Therapy Other: Standard of care Not Applicable

Detailed Description:

Enrolled subjects will be randomized to receive one of two treatment courses: a) MIST Therapy in conjunction with standard of care (SOC) (treatment group); or b)SOC alone (control group).

On post-op day 1, subjects will undergo a baseline evaluation prior to initiating assigned study treatment, including: wound measurement, wound bed evaluation, description of periwound skin, measurement of type and quantity of exudation, wound clinical symptoms (pain, burning, itching), and digital photography. Subject will then receive assigned study treatment.

SOC includes, but is not limited to, fluid resuscitation, pain medications, systemic antibiotics, control of bleeding, and standard dressings as appropriate for the moisture balance of the wound. SOC also includes providing a hydrocolloid border around the wound with a transparent film dressing over the donor site. No advanced or impregnated dressings are allowed during the study. No topical antibiotics or antibiotic dressings, topical antiseptics (silver, iodine, etc.,) or antimicrobials are allowed.

The transparent film will be removed each day and wound fluid will be collected for analysis. After wound fluid collection, subjects will receive their assigned study treatment. Subjects randomized to receive MIST Therapy will be treated daily for 5 consecutive days. Following administration of the assigned study treatment, subjects will have replacement of the transparent film. The hydrocolloid will remain in place on the border of intact skin.

Evaluations performed will include a wound assessment, digital photography, wound pain assessment and an adverse event assessment. Following the initial 5 day treatment, the study wounds will be dressed per SOC with dressing changes as needed.

Subjects will undergo a weekly wound assessment through 6 weeks from the date of study enrollment. A weekly wound assessment will include the assessment of maintained wound closure, digital photography, and an adverse event assessment.

Primary Outcome Measures :
  1. Rate of Wound Healing [ Time Frame: Days to absence of drainage from the initial donor site harvest procedure ]
    The primary endpoint is an average of the group for each participant's donor site wound closure time, defined as days to absence of drainage from the date of the initial donor site harvest procedure.

Secondary Outcome Measures :
  1. Time to Full Epithelialization [ Time Frame: Days to full epithelialization ]
    Time to full epithelialization in days from the date of initial donor site harvest procedure per the blinded adjudication of the donor site image.

  2. Numeric Pain Score [ Time Frame: 5 weeks ]
    Average donor site pain score for each treatment group, numeric scale of 0 (no pain) to 10 (worst possible pain), at five weeks post skin graft procedure

  3. Numeric Itching Score [ Time Frame: 5 weeks ]
    Average donor site itching score for treatment group, numeric scale 0 (no itch) to 10 (worst possible itch), at 5 weeks post skin graft procedure

  4. Donor Site Recidivism Rate [ Time Frame: 6 weeks ]
    Number of donor sites that healed and then reopened during the study.
