简要总结
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.
详细描述
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.

结局指标
主要结局
Rate of Wound Healing
时间窗: 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.
次要结局
- Time to Full Epithelialization(Days to full epithelialization)
