The Effect of OASIS Ultra on Critical Sized Wound Healing

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01848821

Brief Summary:
The aim of this study is to evaluate the speed and quality with which OASIS® Ultra (Healthpoint Biotherapeutics; Fort Worth, Texas) increases wound healing in the critical sized defect. The investigators intend on confirming the histological composition of the dermal substitute in order to delineate the amount of cellular recruitment, collagen deposition and neovascularization present compared with control wounds. The investigators hypothesize that OASIS® Ultra will provide a faster healing time as well as the re-establishment of a dermis for further skin graft application. The investigators anticipate that our study will define parameters for the application of OASIS® Ultra as well as potentially demonstrating the advantages in healing time, healed wound quality and hospital stay.

Arm Intervention/treatment
OASIS half of wound
OASIS will be applied to one half of the wound and standard of care consisting of wound vac only will be applied to the other half.
Device: OASIS Ultra
Porcine derived intestinal submucosa

Standard therapy half of wound
Standard therapy to half of wound will consistent of non-stick mesh and wound VAC application.
Device: Wound VAC Standard Therapy
Negative pressure wound device aka wound VAC will be placed on the standard therapy half of the wound
Other Name: Negative Pressure Wound Device

Primary Outcome Measures :
  1. Wound size [ Time Frame: 60 days ]
    Wound size will be assessed by serial photography and surface area measurement.

Secondary Outcome Measures :
  1. Wound healing quality [ Time Frame: 60 days ]
    serial wound edge biopsies will be obtained to assess vascularity, collagen deposition and cellularity of the wound edge in each arm.
