What is BTM and how does it work?
What is BTM? When trauma to the skin occurs, large portions of the surface of the skin (epidermis) and its deeper layers (dermis) are destroyed. NovoSorb ® BTM (Biodegradable Temporizing Matrix) may be used to temporarily close the wound and aid the body in generating new tissue.
How is BTM applied to wounds?
BTM is applied to a wound once the unhealthy or dead tissue has been surgically removed. BTM temporarily closes the wound, which limits moisture loss 2. Cellular migration into the matrix results in new blood vessel formation and collagen production throughout the matrix.
What does novosorb BTM stand for?
NovoSorb™ BTM (Biodegradable Temporizing Matrix) NovoSorb™ BTM (Biodegradable Temporizing Matrix) is indicated for the management of wounds including: partial- and full-thickness wounds, pressure ulcers, venous ulcers, diabetic ulcers, chronic and vascular ulcers, surgical wounds (donor sites/grafts, post-Mohs surgery, post-laser surgery,...
What is biodegradable temporizing matrix BTM?
NovoSorb™ BTM (Biodegradable Temporizing Matrix) is designed to be placed into a newly created wound bed and stapled/sutured to the edge of the wound. PolyNovo North America LLC is a global medical device company focused on the advancements in regenerative technologies for burn and wound care.
Is BTM sterile?
Can BTM be applied to a wound?
What is BTM in wound?
Biodegradable Temporizing Matrix (BTM) is a synthetic device used to facilitate the growth of neodermis prior to definitive wound closure. BTM is useful in management of full thickness burns, degloving injuries, and necrotizing skin and soft tissue infections.
What is BTM skin substitute?
Currently BTM is the only synthetic, nonbiological, polyurethane temporal dermal substitute intended for use in replacement of tissue loss. 10. BTM is composed of three layers including biodegrading foam, bonding layer, and sealing membrane which acts as an interface for deep burns down to the muscle.
What is BTM medical?
Biodegradable Temporising Matrix (BTM) for the reconstruction of defects following serial debridement for necrotising fasciitis: A case series - ScienceDirect.
What is BTM Polynovo?
NovoSorb® BTM (Biodegradable Temporizing Matrix) is a synthetic, biodegradable and biocompatible device designed to facilitate the dermis to grow within a patented polyurethane matrix. When ready, the sealing membrane is removed, leaving a fully vascularized dermis, ready for definitive closure.
What is split skin graft?
A split skin graft (SSG) is where a very thin shaving of normal, healthy skin is used to cover an area of skin that has been damaged or cannot heal because of an injury (e.g. a severe burn) or abnormality (e.g. ulcer, skin lesion).
What does VAC dressing stand for?
What is vacuum-assisted closure of a wound? Vacuum-assisted closure of a wound is a type of therapy to help wounds heal. It's also known as wound VAC. During the treatment, a device decreases air pressure on the wound.
What is the full form of BTM?
The Full form of BTM is Business Technology Management, or BTM stands for Business Technology Management, or the full name of given abbreviation is Business Technology Management.
What are the reasons for the use of sterile mineral oil when preparing to take a split thickness skin graft?
Mineral oil is used to lubricate the donor site before skin graft harvest and allows for improved sliding of the dermatome. An epinephrine soaked sponge (1 vial of 1:1000 epinephrine in 500 milliliters of 0.9% normal saline) is placed on the donor site following harvest to minimize blood loss.
What is Integra dressing?
Integra® Wound Matrix is an advanced wound care device comprised of a porous matrix of cross-linked bovine tendon collagen and glycosaminoglycan. The collagen-glycosaminoglycan biodegradable matrix provides a scaffold for cellular invasion and capillary growth.
What is Polynovo BTM made of?
NovoSorb BTM is a man-made synthetic polymer that does not contain any biologic materials. This is important because traumatic wounds often contain bacteria that may cause infection.
What is Acticoat?
ACTICOAT is a range of dressings that utilize the antimicrobial properties of silver to provide an efficient and effective barrier to bacterial penetration. 3. Flexible, absorbent and conformable, each ACTICOAT variant is developed with properties specific to its required use.
How do you use MatriDerm?
MatriDerm can be applied straight from the pack onto the wound bed following the debridement of any slough, exudate or unhealthy tissue, and after careful haemostasis. The matrix can easily be rehydrated in the wound bed by 0.9% physiological saline solution.
Abstract
Serial debridement of tissue affected by necrotising fasciitis results in extensive and deep wounds, sometimes complicated by the exposure of major vessels, tendons, bone or other tissue incapable of supporting healing by skin grafts alone. When skin grafts are used, their contraction can result in contracture of joints, or the neck.
1. Introduction
Necrotising fasciitis is a synergistic gangrene which is increasing in prevalence [1], with 628 cases presenting to Australian hospitals in 2016/17. It is associated with significant mortality; causing 290 deaths between January 2009 and February 2018 (unpublished data).
2. Methods
All cases in which BTM has been employed in necrotising fasciitis wound reconstruction have been included. Medical records and operations notes were reviewed retrospectively, including clinical photographs. Photographs were taken of all wounds at each surgery and dressing change.
3. Results
Seven cases have been reconstructed in the last two years, in two-stages, where BTM represented the first stage and split skin autografting the second ( Table 1 ). The mean age was 58 years (31 to 88 years), and the male to female ratio = 3:4.
4. Discussion
The aim of wound closure after any injury is a functional result, which is cosmetically acceptable. Radical debridement for soft tissue infections, following trauma, or to achieve an adequate surgical margin after cancer excision, often leaves a wound indicating reconstruction by free tissue transfer for coverage of ungraftable structures.
5. Conclusion
BTM already has an established central role in our management of severe and extensive burn injury. We are now satisfied that, where indicated for temporising wound and patient, seeking aesthetic contour and uniformity of wound cover, and coverage of exposed bone and tendon, BTM also has a beneficial role in necrotising fasciitis defects.

Is BTM sterile?
BTM is sterile if the package is unopened and undamaged. Do not use if the package has been perforated or the seal is broken or any other contamination is suspected. Opened and unused BTM cannot be resterilized and must be discarded.
Can BTM be applied to a wound?
BTM should not be applied into overtly infected wounds, such wounds should be debrided of non-vital tissue and be topically treated with antimicrobial dressings +/- systematic antibiotics before application is considered.
