“T” Tissue – non-viable or deficient

The first step in Wound Bed Preparation is to remove the necrotic tissue. This process is important for several reasons:
1. Devitalized tissue (eschar and slough) in the wound bed will reduce the ability of the clinician to adequately assess the depth of the wound, condition of the tissue and surrounding structures.
2. It may mask signs of infection and serve as a medium for the proliferation of bacteria.
3. The presence of necrotic tissue is a physical barrier to healing and necrotic tissue supports significant bacterial growth which may result in excessive amounts of proteases which can have a very negative effect on healing.

“I” Infection or inflammation

The presence of a wound creates a portal of entry for bacteria. One of the most significant predisposing factors for a wound infection is inadequate blood supply. For example in pressure ulcers or ischemic leg ulcers.
This pressure ulcer is covered with eschar & has evidence of surrounding cellulitis. A swab culture is insufficient in this case. The eschar is being unroofed & a direct culture is obtaining at that point.

Interventions for a non-advancing wound margin may include debridement, biological agents, skin grafts, and adjunctive therapies. Debridement of necrotic tissue or callus (in the case of neuropathic ulcers) may be helpful for the non-advancing wound edge. Biologic agents include Human Fibroblast-Derived Dermal Substitute and growth factors (applied at the right time).

Surgical debridement
When properly performed, surgical wound debridement removes devascularized tissue and necrotic material, eliminates dead space and reduces wound contamination
![Page 11: Tangential Hydrosurgery: A Paradigm Shift in Surgical ... · • Describe the concept of Wound Bed Preparation ... and into the evacuation collector creating a localized ... Photo](https://reader031.fdocuments.us/reader031/viewer/2022022007/5acedb097f8b9a56098c5077/html5/thumbnails/11.jpg)
Classic Principles of Surgical Debridement
•Early, radical excision
•Rapid resuscitation
•Removal of necrotic tissue
•Preservation of viable skin
•Planned incisions to facilitate reconstruction
•Inspect deep fascia and muscle
•Pack wound
•Reoperate if necessary

The Clinical Benefits of Debridement• Removes necrotic tissue that impairs wound healing
• Creates bacterial balance in the wound
• Results in controlled bleeding that stimulates the production of blood-borne growth factors
• Removes the senescent fibroblasts – leaving younger, more viable cells
• Removes the hyperproliferative, non-migratory wound edge that slows healing
Thorough debridement is essential for the wound repair process.

Versajet® – An Advanced Hydrosurgery Product
Venturi EffectThe design of the VersaJet is such that the high-velocity fluidjet passes across the operating window and into the evacuation collector creating a localized vacuum to hold and cut targeted tissue while aspirating debris from the site.
Tissue ExcisionAdditional design attributes allow the user to finely control excision. Orienting the operating window parallel to the tissue optimizes the VersaJet’s performance for tissue excision – cutting and aspiration.
Contaminant RemovalAlternatively, orienting the operating window obliquely to the tissue optimizes the VersaJet’s performance for contaminant removal – irrigation and vacuuming.

The mean cost of a surgical debridement at University Hospital was $3,393. On this basis, the expected cost of debridement was $6,700 per patient with conventional techniques (mean of 2 procedures per patient) compared with $3,900 with the waterjet (mean of 1.14 procedures).No health and safety issues (eg, sharps injuries, splash-back contamination) were reported with the use of the waterjet during the study period.

This patient had a streptococcal invasive infection and was profoundly hypotensive and acidotic .Following debridement with Versajet she was out of the operating room and completely excised and debrided in one sitting.

Through the use of the VERSAJET, a healthy wound bed was obtained with minimal injury to collateral tissue and complete removal of road dirt. Sharp tangential excision is difficult toperform with accuracy over curved surfaces such as the breast. The debridement had to remove road dirt as well as remain superficial enough to preserve the areolar pigment. The additional of advanced therapies, such as negative pressure therapy and acellular dermal matrix, facilitated a rapid and successful recovery with minimal scar deformity.

Summary
• In the scheme of the “TIME” sequence, waterjetdebridement quickly moves the wound through all phases of wound bed preparation
• Paradigm shift in surgical management
