What are the 4 types of skin grafts?

Depending on the origin:

• Autograft or autologous graft: skin obtained from the patient’s own donor site.
• Allograft or heterologous graft: skin obtained from another person.
• Xenograft or heterograft: skin from other species, such as pigs.
• Synthetic skin substitutes: manufactured products that work as skin equivalents.

What is biobrane made of?

Biobrane® is a flexible biosynthetic wound dressing constructed of silicone bonded to woven nylon containing peptides derived from type I porcine collagen. The use of Biobrane ® has been shown to significantly reduce hospital stay, wound healing time, and pain in comparison to other dressings.

What is Matriderm?

Matriderm (MedSkin Solution Dr. Suwelack AG, Billerbeck, Germany) is a highly porous membrane composed of three-dimensionally coupled collagen and elastin. The collagen of the matrix is obtained from the bovine dermis, and the elastin is obtained from the bovine nuchal ligament by hydrolysis.

What are fibroblasts and keratinocytes?

Fibroblasts and keratinocytes are two of the major cell types that respond to the inflammatory phase in the cutaneous repair/regeneration process. Inflammatory signals activate the proliferation and maturation of these two cells types, which is essential for wound healing.

What are the 3 types of skin grafts?

There are different types of grafts according to their origin, thickness and form. There are 3 main types of graftsthat are used to cover wounds: Split-thickness skin grafts, full-thickness skin grafts and composite grafts. Each of them has specific indication and has a unique technique for harvesting.

What is autograft and allograft?

A patient’s own tissue – an autograft – can often be used for a surgical reconstruction procedure. Allograft tissue, taken from another person, takes longer to incorporate into the recpient’s body .

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.

When do you use biobrane?

In burns surgery, Biobrane gloves are used within the first 24 hours to cover clean partial-thickness burn wounds of the hand. The glove promotes early movement of the burned hand and helps create a barrier from infection.

What is NovoSorb BTM?

NovoSorb® BTM (Biodegradable Temporizing Matrix) may be used to temporarily close the wound and aid the body in generating new tissue. 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.

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.

What is a fibroblast?

A fibroblast is a type of cell that contributes to the formation of connective tissue, a fibrous cellular material that supports and connects other tissues or organs in the body. Fibroblasts secrete collagen proteins that help maintain the structural framework of tissues.

Are fibroblasts in the epidermis?

Dermal fibroblasts are the main cell type present in skin connective tissue (dermis). Fibroblasts interact with epidermal cells during hair development and in interfollicular skin.

What is the difference between a skin graft and a flap?

How does a flap differ from a graft? A flap is transferred with its blood supply intact, and a graft is a transfer of tissue without its own blood supply. Therefore, survival of the graft depends entirely on the blood supply from the recipient site. Flap surgery is a subspecialty of plastic and reconstructive surgery.

What is xenograft and allograft?

An allograft is a material derived from one person and implanted in another person. A xenograft is a material derived from any nonhuman animal that is implanted in a human.

What is the difference between autograft and xenograft?

Autograft: transplantation of tissue excised from one place and grafted to another in the same individual. II. Syngraft (isograft): transplantation of tissue excised from one individual and grafted to another who is identical genetically.

What is mepitel used for?

Mepitel with Safetac protects the wound and the skin. It’s designed and clinically proven for use in treating a wide range of wounds such as skin tears, skin abrasions, sutured wounds, partial thickness burns, lacerations, partial and full thickness grafts, diabetic ulcers, venous and arterial ulcers.

What is collagen dressing?

Collagen dressings are sheets, pads and gels derived from usually bovine or porcine collagen. They can play a crucial role in the wound healing process as they encourage cell proliferation, angiogenesis and collagen deposition into the wound bed.

How is biobrane made?

BIOBRANE is composed of a silicone membrane bonded to a nylon mesh to which peptides from a porcine dermal collagen source have been bonded to the nylon membrane to form a flexible and conformable composite dressing. BIOBRANE has been proven to provide: Decreases length of patient stay. Increased speed of healing.

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.

How does dermagraft work?

Dermagraft delivers a collagen-rich living human dermal matrix to the prepared ulcer wound bed. Metabolically active fibroblasts are distributed throughout the Dermagraft and retain the capacity for secreting a variety of regulatory and structural proteins.
