Clinical Trial Summary

The purpose of this study is to determine if the use of silicone material inserts within pressure garments is effective in decreasing hypertrophic burn scar formation as compared to standard pressure garment therapy.


Description:

Surgical revision, potential hospitalization, and extensive post-surgical rehabilitation may be required for the revision and correction of hypertrophic burn scars to restore function and prevent disability. This in turn results in an increased financial burden to the medical system. More importantly, the patient is required to undergo an additional invasive medical procedure that can potentially create further hypertrophic scarring.

Prevention and reduction of hypertrophic scars with non-invasive, cost effective, and evidence based treatment modalities is therefore the most desirable approach. Two of the most generally accepted methods of non-invasive treatment, pressure garments and silicone gel sheeting, have been demonstrated to individually treat hypertrophic scarring. Recently, burn therapists have begun to use silicone bonded material inserts within pressure garments following the logical deduction that the two therapeutic techniques can be combined to resolve many of the cited individual disadvantages, while reaping the benefits of each individual modality. It is the aim of this study to determine the efficacy of these silicone bonded material inserts within pressure garments in the treatment of hypertrophic scarring.

Outcome

Type Measure Description Time frame Safety issue
Other Scar height The Modified Vancouver Scar Scale (MVSS) will be used to measure the scar pliability. It is a therapist-judged hand held tool that measure scar properties on an ordinal scale. A baseline evaluation will be performed at the time of initial pressure garment fitting, and follow up evaluations will take place at 1 month, 3 months, 6 months and 12 months after pressure garment fitting.
Other Scar itch Scar itch will be measured using a visual analogue scale (VAS). A baseline evaluation will be performed at the time of initial pressure garment fitting, and follow up evaluations will take place at 1 month, 3 months, 6 months and 12 months after pressure garment fitting.
Other Scar Appearance Will be measured using a visual analogue scale (VAS). A baseline evaluation will be performed at the time of initial pressure garment fitting, and follow up evaluations will take place at 1 month, 3 months, 6 months and 12 months after pressure garment fitting.
Other Comfort of garment Will be measured using ordered response scales. A baseline evaluation will be performed at the time of initial pressure garment fitting, and follow up evaluations will take place at 1 month, 3 months, 6 months and 12 months after pressure garment fitting.
Other Limitations to movement Will be measured using ordered response scales. A baseline evaluation will be performed at the time of initial pressure garment fitting, and follow up evaluations will take place at 1 month, 3 months, 6 months and 12 months after pressure garment fitting.
Primary Scar pliability measured in gm/mm squared The Modified Vancouver Scar Scale (MVSS) will be used to measure the scar pliability. It is a therapist-judged hand held tool that measure scar properties on an ordinal scale. Because the MVSS is a subjective rating system, we will also be using the NK Skin Compliance Device (SCD)to measure scar pliability. It is a non-invasive hand-held device that measures skin compliance or pliability. A baseline evaluation will be performed at the time of initial pressure garment fitting, and follow up evaluations will take place at 1 month, 3 months, 6 months and 12 months after pressure garment fitting.
Secondary Scar vascularity The Modified Vancouver Scar Scale (MVSS) will be used to measure the scar pliability. It is a therapist-judged hand held tool that measure scar properties on an ordinal scale. A baseline evaluation will be performed at the time of initial pressure garment fitting, and follow up evaluations will take place at 1 month, 3 months, 6 months and 12 months after pressure garment fitting.
