Integra® Meshed Dermal Regeneration Template

Integra® Meshed Dermal Regeneration Template is an advanced bilayer matrix consisting of a porous, three-dimensional dermal replacement layer and a temporary epidermal layer. The dermal replacement layer (collagen and glycosaminoglycan) is designed with a controlled porosity and defined degradation rate to promote neodermal formation. The epidermal layer (pre-meshed polysiloxane) provides a moisture and bacterial barrier.

• FDA-approved for partial- and full-thickness third-degree burns and reconstruction of scar contracture
• Biodegrades while being replaced with autologous tissue
• Promotes cellular growth and collagen synthesis
• Pre-meshed configuration saves time in the OR
• Consistent meshed design allows better conformity to the wound bed and ease of handling

Integra® Meshed Dermal Regeneration Template is indicated for the post-excisional treatment of life-threatening full-thickness or deep partial-thickness thermal injuries where sufficient autograft is not available at the time of excision or not desirable due to the physiological condition of the patient. Integra® Meshed Dermal Regeneration Template is also indicated for the repair of scar contractures when other therapies have failed or when donor sites for repair are not sufficient or desirable due to the physiological condition of the patient.

Contraindicated in patients with known hypersensitivity to bovine collagen or chondroitin materials. Integra® Meshed Dermal Regeneration Template should not be used on clinically diagnosed infected wounds.

Excision of the wound must be performed thoroughly to remove all coagulation eschar and nonviable tissue. Integra® Meshed Dermal Regeneration Template will not "take" (incorporation into the wound bed) to nonviable tissue. Leaving any remaining nonviable tissue may create an environment for bacterial growth. Hemostasis must be achieved prior to applying Integra® Meshed Dermal Regeneration Template. Inadequate control of bleeding will interfere with the incorporation of Integra® Meshed Dermal Regeneration Template.
There have been no clinical studies evaluating Integra® Meshed Dermal Regeneration Template in pregnant women. Caution should be exercised before using Integra® Meshed Dermal Regeneration Template in pregnant women. Such use should occur only when the anticipated benefit clearly outweighs the risk. In clinical trials, the use of Integra® Meshed Dermal Regeneration Template was evaluated in a small number of patients with chemical, radiation or electrical burns. A surgeon's decision to use Integra® Meshed Dermal Regeneration Template on these wounds should be based on their evaluation of the wound and its suitability for excisional therapy, the likelihood that a viable wound bed will be created by excision and whether the possible benefit outweighs the risk in this patient population.
Integra® Meshed Dermal Regeneration Template should be applied on the day of excision. Delaying the application of Integra® Meshed Dermal Regeneration Template may substantially impair the take of the material.
Appropriate techniques to minimize pressure and shearing should be used to reduce risk of mechanical dislodgement.
Placing the patient in hydrotherapy immersion may interfere with proper incorporation of the Integra® Meshed Dermal Regeneration Template and cause premature separation of the silicone layer and nonadherence of the template. Caution must be employed to not remove the newly formed neodermal tissue when removing the silicone layer. Integra® Meshed Dermal Regeneration Template must NOT be excised off the wound.

Integra® Meshed Dermal Regeneration Template has been found to be well tolerated in four prospective clinical trials involving 444 burn patients. There were no reports of clinically significant immunological or histological responses to the implantation of Integra® Meshed Dermal Regeneration Template. There were no reports of rejection of Integra® Meshed Dermal Regeneration Template.
Adverse events in the Postapproval study were similar to those observed in the previous clinical trials and are common in populations of critically ill burn patients regardless of type of treatment used. There were no trends noted. There were six adverse events which were rated by the investigator as being related. These events were all single occurrences except for sepsis (2). These adverse events occurred in less than 1% of the safety population.

Store flat at 2°C-30°C. Protect from freezing.

Always handle Integra® Meshed Dermal Regeneration Template using aseptic technique. Peel open the outer pouch and remove the inner foil pouch using sterile technique. Place foil pouch flat on a sterile surface and peel it open. Remove product, including the protective polyethylene cover sheets. While holding the product with the tab, remove one polyethylene cover sheet. Turn the product and remove the second polyethylene cover sheet. Using the tab, the product can now be placed into a basin containing sterile saline solution. Carefully remove the tab from the product. Rinse the product by immersion in sterile saline for one to two minutes. Keep product in the basin until application.
Wound Excision
Excision must be made to the level of viable tissue and meticulous hemostasis must be achieved before application of Integra® Meshed Dermal Regeneration Template. Excisional techniques for Integra® Meshed Dermal Regeneration Template sites can be fascial, sequential or tangential. It is absolutely critical to the successful take of Integra® Meshed Dermal Regeneration Template that excision be complete and that no devitalized tissue remains. Complete hemostasis must be achieved before application of Integra® Meshed Dermal Regeneration Template. The presence of hematoma will cause loss of Integra® Meshed Dermal Regeneration Template in the affected area. Broad area cauterization that could decrease wound bed viability should be avoided.
Shaping Integra® Meshed Dermal Regeneration Template to Fit the Wound
Integra® Meshed Dermal Regeneration Template should be shaped accurately to fit the excised wound margins to minimize scarring at these margins. It should not be overlapped onto non-excised areas or onto other sheets of Integra® Meshed Dermal Regeneration Template. It is easily cut with sterile scissors by placing the sheet of Integra® Meshed Dermal Regeneration Template over the excised wound bed and cutting exactly to the edge.
Applying Integra® Meshed Dermal Regeneration Template to the Wound
It is critical that the collagen template layer be in direct contact with the excised wound. The silicone layer (identified by the black threads) must be placed out (away from the wound bed). Do not apply upside down; the black threads must be clearly visible. For optimal cosmetic results, place the Integra® Meshed Dermal Regeneration Template so that the suture lines between Integra® Meshed Dermal Regeneration Template sheets lie in Langer's lines. This will minimize the final appearance of the suture lines.
The Integra® Meshed Dermal Regeneration Template sheets are secured by staples or sutures placed in an interrupted fashion under slight tension. If the Integra® Meshed Dermal Regeneration Template has been meshed, care must be taken not to spread the mesh. Care should be taken to achieve a primary closure between Integra® Meshed Dermal Regeneration Template and adjacent unburned skin or between sheets of Integra® Meshed Dermal Regeneration Template. Suture or staple each sheet of Integra® Meshed Dermal Regeneration Template in place independently. The Integra® Meshed Dermal Regeneration Template sheets may also be affixed to one another to assure that there is no gap between sheets. Adjust the area to ensure that there is no undue tension on an individual piece of Integra® Meshed Dermal Regeneration Template. The material should readily adhere and conform to the wound surface. Any air bubbles should be carefully removed by moving them to the edge of the sheet. Dressings should be applied over Integra® Meshed Dermal Regeneration Template according to the protocol of the practitioner.
