Evaluation of HQ® Matrix Medical Wound Dressing for Healing of Donor Site Wounds

Number of Participants With Growth of Granulation Tissue

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.

Time frame: Days 0, 3±1, 7±1, 10±2, 14±3, and 21±3 post-operation

Number of Participants With Inflammatory Reaction

Physician assessment determined presence of inflammatory reaction which is characterized by pain, heat, redness and swelling.

Time frame: Days 0, 3±1, 7±1, 10±2, 14±3, and 21±3 post-operation

Pain Perceived by Patient

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).

Time frame: Days 0, 3±1, 7±1, 10±2, 14±3, and 21±3 post-operation

Number of Participants With Exudation

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 (++);

Time frame: Days 0, 3±1, 7±1, 10±2, 14±3, and 21±3 post-operation
