Brief Summary:

Researchers at LSUHSC-S hope to learn the effects of the combination of a medication and a device which by themselves are effective for the treatment of wounds.

You are being asked to take part in this study because you have a wound on your body which has not responded to standard treatments.

The researchers will be studying whether the combination of two treatments will make wounds heal faster. For those in study, the investigators will treat them with a vacuum device on their wound. Also, some of the people in the study will receive a special ointment and researchers will use special tests to determine if the two treatments together are working better than just one treatment alone.

Condition or disease Intervention/treatment Phase
Pressure Ulcer Soft Tissue Necrosis Lower Limb Device: Negative Pressure Wound Therapy Biological: Collagenase Ointment Not Applicable

Detailed Description:
Evaluate the effectiveness of Collagenase Santyl ointment when used in conjunction with NPWT for the treatment of chronic pressure ulcers and determine whether the addition of Collagenase Santyl ointment has a positive effect on wound healing. Through volumetric changes and histological evaluation, we wish to test the hypothesis that the application of Collagenase Santyl ointment in conjunction with NPWT facilitates improved wound healing and mitigates some potentially harmful effects of NPWT alone (e.g. pain with dressing removal and tissue ingrowth

Arm Intervention/treatment
Active Comparator: Negative pressure wound therapy
NPWT changed TIW
Device: Negative Pressure Wound Therapy
