Clinical Efficacy of the Novel Biocellulose Wound Dressing Containing Silk Sericin and Polyhexamethylene Biguanide for Split-thickness Skin Graft Donor Sites

  1. The wound healing time of STSG donor sites which are treated with the novel biocellulose wound dressing containing silk sericin and PHMB should be less or equal to Bactigras®.

  3. The amounts of STSG donor site infection which are treated with the novel biocellulose wound dressing containing silk sericin and PHMB should not be more than Bactigras®.
  4. The pain level of STSG donor sites which are treated with the novel biocellulose wound dressing containing silk sericin and PHMB should be less or equal to Bactigras®.

Detailed Description

The goals of STSG donor site treatment are to accelerate wound healing, prevent infection, reduce pain, and maintain an optimal environment healing promotion. Biocellulose is an ultrafine fiber structure that can hold a large amount of water and has a cooling effect that decreases pain without causing an allergic reaction or irritation.Silk sericin (SS) can activate the growth of fibroblast cells which promote collagen type I production and accelerated wound healing without toxicity . Polyhexamethylene biguanide (PHMB) is a broad spectrum antimicrobial agent with high efficacy and low toxicity. Therefore, the combination of silk sericin and PHMB in biocellulose dressings would benefit STSG donor site wound treatment. The purpose of this study is to investigate the clinical efficacy of this dressing for STSG donor site wound treatment compared with Bactigras® (chlorhexidine acetate 0.5% in white soft paraffin), which is the standard dressing for this type of wound at King Chulalongkorn Memorial Hospital, by monitoring the time required for complete re-epithelization, wound quality, the rate of infection, pain, and the adverse events from December 2015 to November 2016. Thirty two subjects (more than 18 years) with STSG donor site at thigh will be recruited in this study. Block randomization will be used for separation half of eligible wound to cover with novel biocellulose wound dressing containing silk sericin and PHMB or Bactigras®. Wound healing time is the day that the dressing detaches by itself with no exudate and air contacted pain. Wound quality at 1,3,and 6 months will be measured in terms of erythema level, melanin level, transepidermal water loss by using Cutometer® and scar quality (vancouver scar scale). Sign of infection, pain (VAS score), hepatic and renal function will also be collected.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Experimental: The novel biocellulose wound dressing
Device: The novel biocellulose wound dressing
The novel biocellulose dressing will used as a primary dressing at one half of the donor site. Then,the wound will be covered with 2 layers of gauze (secondary dressing) and 1 layer of bandage.The primary dressing will be unchanged until the wound healing (the day that the dressing detaches by itself with no exudate and air contacted pain) except signs of infection. The secondary dressing will be changed when excessive fluid appears.
Other Names:
  • Biocellulose dressing containing silk sericin and PHMB
Active Comparator: Bactigras
Device: Bactigras
Bactigras will used as a primary dressing at another one half of the donor site. Then,the wound will be covered with 2 layers of gauze (secondary dressing) and 1 layer of bandage.The primary dressing will be unchanged until the wound healing (the day that the dressing detaches by itself with no exudate and air contacted pain) except signs of infection.
