Brief Summary:
This is a prospective, descriptive, pilot case series involving patients with significant burns who are candidates for reconstruction with Integra®. Subjects would have a small area of the wound would, at the time of excision, have the smallest sheet of thin Integra® (125 cm2) placed and be immediately autografted with a 3:1 meshed split-thickness skin graft. Of note, 125 cm2 represents approximately 0.7% of an average sized patient's total body surface area, so for even the smallest burns in our proposed trial, this area would represent a small portion of the patient's area of injury. The remaining injury areas would be covered with standard-thickness Integra® only.

Condition or disease Intervention/treatment Phase
Thermal Burn Device: thin Integra® (125 cm2) Not Applicable

Detailed Description:

Integra®, a synthetic dermal substitute, has been utilized in burn care for decades. Typically, 10-14 days after Integra® placement, a patient returns to the operating room, the top silastic layer of the Integra® is removed, and an autograft - a split-thickness skin graft harvested from the patient - is applied directly on top of the incorporated Integra®. The result is regarded to be a cosmetically and functionally superior result to that which would have been obtained had the wound bed itself been autografted at the time of excision, as opposed to being covered by Integra® and autografted during a second operation.

Integra® use in single-stage procedures to cover defects without grafting has shown benefit when defects are fairly small, e.g. fingertip injuries, and small head and neck skin cancer resections. While single-stage reconstruction with Integra® has been demonstrated with standard thickness Integra®, this decreased thickness would increase the likelihood of graft survival due to the decreased distance of nutrient diffusion.

Arm Intervention/treatment
Experimental: Single-stage Integra
Composed of a porous collagen-chondroitin 6-sulfate fibrillary mat covered with a thin sheet of silastic, it serves to cover wound beds of freshly excised burns and allow for the infiltration of fibroblasts, capillaries, and macrophages, essentially creating a "neodermis" while also acting as a barrier against infection and a blockade against heat and moisture loss
Device: thin Integra® (125 cm2)
125 cm2 represents approximately 0.7% of an average sized patient's total body surface area. The remaining injury areas would be covered with standard-thickness Integra® only. The donor graft, a 4 cm x 10 cm sheet of skin, would be meshed in a 3:1 ratio to be expanded to cover the 125 cm2 sheet of thin Integra®. The patient's post-operative care would be largely unchanged, although the patient would have a donor site of 40 cm2 that would be dressed and managed in the usual fashion.
Other Name: Integra®

Primary Outcome Measures :
  1. The time to 95% healing of the single-stage reconstructed skin graft [ Time Frame: Up to 12 months ]
    95% healing determined as charted in Standard of Care follow up visits

Secondary Outcome Measures :
  1. Frequency of complications: infection, seroma, hematoma, sloughing, and graft loss [ Time Frame: Up to 12 months ]
    Compared to the same characteristics of the adjacent (control) 125 cm2 skin graft

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 125 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • English-speaking adult burn patients greater than 18 years old, admitted with burn injuries eligible for Integra® reconstruction at the discretion of the burn attending physicians.

Exclusion Criteria:

  • patients with isolated hand or face burns - these burns are treated with sheet grafts (unmeshed); the 3:1 mesh grafts would not be used on these cosmetically sensitive areas. If they have hand and/or face burns in addition to other areas, they will not be excluded. However, the study itself will not be performed on the hands or face. Additionally, patients unable to present to our clinic for routine follow-up due to geographic limitations or otherwise will be ineligible.
