Primary Outcome Measures:
  • Time to Wound Healing [ Time Frame: Days 0, 3±1, 7±1, 10±2, 14±3, and 21±3 post-operation ]
    Healing time was recorded when complete re-epithelialization had occurred. If the wound healed in advance, visit until the wound was completely healed. If the wounds were unable to heal for more than 21±3 days, unanticipated follow-ups were added until the wound was completely healed.


Secondary Outcome Measures:
  • Number of Participants With Growth of Granulation Tissue [ Time Frame: Days 0, 3±1, 7±1, 10±2, 14±3, and 21±3 post-operation ]
    Physician assessment of tissue with healthy granulation tissue defined as is granular and uneven in texture, does not bleed easily and is pink in color. Unhealthy granulation tissue is typically dark which can be indicative of poor perfusion, ischemia and/or infection.

  • Number of Participants With Inflammatory Reaction [ Time Frame: Days 0, 3±1, 7±1, 10±2, 14±3, and 21±3 post-operation ]
    Physician assessment determined presence of inflammatory reaction which is characterized by pain, heat, redness and swelling.

  • Pain Perceived by Patient [ Time Frame: Days 0, 3±1, 7±1, 10±2, 14±3, and 21±3 post-operation ]
    The amount of pain that a patient perceived was assessed using a Visual Analogue Scale (VAS 0-10), which ranges across a continuum from 0 (no pain) to 10 (worst pain).

  • Number of Participants With Exudation [ Time Frame: Days 0, 3±1, 7±1, 10±2, 14±3, and 21±3 post-operation ]

    Physician assessment determined presence of exudation by observing whether the gauze over the primary wound dressings was soaked by exudation:

    1. Less than two gauze was soaked by exudation within 24h---No exudation (-);
    2. Two to four gauze was soaked by exudation within 24h---Little exudation (+);
    3. More than four gauze was soaked by exudation within 24h---Much exudation (++);

Arms Assigned Interventions
Experimental: HQ® Matrix Medical Wound Dressing
After harvesting the graft, the donor site wounds were treated with the dressing material. Dressing changes if needed. An operative removal of the HQ® Matrix Medical Wound Dressing is not required as it becomes spontaneously detached from the regenerated skin areas.
Device: HQ® Matrix Medical Wound Dressing
Other Name: HQ® Matrix
Active Comparator: Sidaiyi® wound dressing
After harvesting the graft, the donor site wounds were treated with the dressing material. Dressing changes if needed.
Device: Sidaiyi® wound dressing
Other Name: Sidaiyi®

Detailed Description:

HQ® Matrix Medical Wound Dressing is a transparent, non-porous, pliable, gas-permeable, and waterproof film dressing which is comprised of silk fibroin protein of the Bombyx mori (B. mori) silkworm. It is intended to provide a moist, gas-permeable and sterile environment to facilitate the normal wound healing process. It is used in the management of non-infected skin defects and various dermal wounds.

Sidaiyi® wound dressing (Suzhou Soho Biomaterial Science and Technology Co., Ltd, Suzhou, China) is a CFDA approved (Su2012-2640182), silk fibroin-based, two-layered spongy dressing. Upon the silk fibroin spongy dressing layer is a membrane made of medical silicone. It is used in the management of partial- and full-thickness wounds, donor site wounds and burns. Currently, it is the sole silk fibroin biomaterial for wound healing that has received regulatory approval worldwide.
