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.

Primary Outcome Measures:
  • Quicker Filling of the Wound With Good Tissue (vs. Treatment With NPWT Alone) [ Time Frame: 2 weeks into study ]

Secondary Outcome Measures:
  • Removal of Harmful Fluids in the Wound Tissue [ Time Frame: 2 weeks into study ]

Enrollment: 2
Study Start Date: June 2010
Study Completion Date: December 2011
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Negative pressure wound therapy
NPWT changed TIW
Device: Negative Pressure Wound Therapy
NPWT changed 3 times weekly
Other Name: NPWT
Experimental: NPWT plus Collagenase Ointment
Collagenase applied TIW with NPWT
Biological: Collagenase Ointment
Apply TIW

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

Ages Eligible for Study:   18 Years to 85 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:
