Study objective:

The objective of this study is to evaluate through clinical criteria the clinical efficacy and safety of BCT Silver Bandage role in obstetrical and gynecological wound healing is as effective and safe as Aquacel® Ag. Dressing.

Study devices:

  • Study device: BCT Silver Bandage
  • Comparator device:"ConvaTec"Aquacel® Ag Hydrofiber Dressing

Study design:

  • Randomized, Open-label, interventional, comparative, preventive study with Blinded evaluator.
  • All subjects must meet all the inclusion & exclusion criteria to enter this study in pre-operative phase.
  • Eligible subjects will be enrolled after a scheduled operative procedure.
  • There is SEVEN visits in this study (one screening eligibility phase up to 7 days before OP day, and four post-op treatment scheduled visits consisting on 1st , 3rd day, 5th day, 12th day and two follow up visit on the 28th and the 42nd post-operative day.
  • During each scheduled visit, each subject will have colored picture of his wound after dressing been removed, and on visit V6 for wound evaluation by blinded PI.

Number of subjects: It is expected to recruit ≧150 eligible subjects.

Study Duration: About eighteen month.

Primary Outcome Measures:
  • Efficacy measurements [ Time Frame: 42 days after operation ]
    1. Wound infection rate within 5 days after operation
    2. Wound healing evaluation by Stony Brook Scar Evaluation Scale (SBSES), to be evaluated by blinded PI at V6
    3. Skin discoloration around the incision wound and/or wound keloid formation rate at V6
    4. Patient and Observer Scar Assessment Scale (POSAS) on V3, V5 and V6

Secondary Outcome Measures:
  • Safety Measurement [ Time Frame: 42 days after operation ]
    The incidence of postoperative skin reactions (defined as blisters, itching, erythematous change around the surgical wound site) within 5 days after operation

Enrollment: 38
