Week 1 - Wound managment Flashcards
Stoma pouch
bag used to collect body fluids following stoma surgery (small opening on the abdominal surface surgically created to divert the flow of feces +/- urine)
Retention sutures
type of interrupted technique used to proved additional support to wound edges in abdominal sx
Purse string suture
special continuous suture technique for closing the end of a tubular structure
Allograft
tissue graft derived from human tissue
Autologous autograft
tissue obtained from pt’s body and implanted in another site
Xenograft
graft derived from animal or synthetic source
Memory
recoil; ability of a suture to return or maintain its orignal shape
Fluid absorption
ability of suture to take up fluid
Conventional cutting needle
needle with the cutting edge on the inside of the curve; triangular shaft
Reverse cutting needle
needle with cutting edge on the outside or lower edge of the needle; stronger than conventional cutting needle; produces minimal scarring
Allogeneic grafts
grafts made from nonliving cadaver bone
Composite grafts
grafts made of a combination of cadaver bone, morcellated allograft bone, and marrow
Keloid
dense, unsightly connective tissue or excessive scar formation
Dead space
air or empty space between layers of tissue or beneath wound edges that have been approximated
Class I wounds
clean wounds; uninfected wounds, no inflammation; respiratory, alimentary (gi) and genitourinary tracts not entered
Class II wounds
clean contaminated; wounds in which respiratory, alimentary, or genitourinary tract entered under controlled conditions; no sign of infection, no beak in surgical aseptic technique
Class III wounds
contaminated wounds; open, fresh, accidental wounds (open fractures, penetrating trauma, operations with major breaks in aseptic tech) incisions with signs of infection or gross spillage from gi tract
Class IV wounds
dirty or infected wounds; old, physically induced with retained devitalized tissue and wounds that involve existing clinical infection or perforated viscera
Traumatic wounds
caused by mechanical, thermal, or chemical destruction
Surgical wounds
caused by an incision or excision
FDA
food and drug administration; federal agency of US dept of health and human services
USP: U.S. Pharmacopia
Pharmacopeia (book containing directions for the identification of compound medicine and published by the authority of a govt or medical or pharmaceutical society) for the US published annually by the US pharmacopeial convention
Skin grafts
used to replace skin that has been destroyed by ds or inury
Double armed suture
one with a needle swaged to each end; used for circular tissue or for hollow structures
Blunt tip needle
round shaft with blunt tip; pushes tissue aside as it moves through, doesn’t puncture
Absorbable suture
suture material that is broken down and metabolized by the body
Adhesion
scar formation of the abdominal viscera
Anastomosis
surgical creation of an opening between two blood vessels, hollow organs, or ducts
Approsimate
to bring tissues together by sutures or other means
Autotransfusion
blood salvaging; method of retrieving blood lost at the operative site, reprossing it, and infusing it back into the pt
Capillary action
ability of suture material to absorb fluid
Contracture
scar tissue that lacks flexibility, causing constriction and pain
Debridement
chemical or mechanical removal of necrotic or nonviable tissue and foreign bodies after infection or trauma
Dehiscence
separation of the edges of a surgical wound during healing
Evisceration
protrusion of abdominal viscera through a wound or surgical incision
Fistula
complication of wound infection in which one or more hollow, skin lined tracts form at the wound site and continue to drain pus and fluid
Hematoma
blood-filled space in tissue, result of a bleeding vessel
Hemostatic agent
substance applied to bleeding tissue in order to enhance clotting
Inert
causing little or no reaction in tissue or with other materials
Interrupted sutures
technique of bringing tissue together by placing individual sutures close together
Ligate
to place a loop or tie around a blood vessel or duct
Nonabsorbable suture
suture material that resists breakdown in the body
Primary intention
wound healing process after a clean surgical repair
Running suture
method of suturing that uses one continuous suture strand for tissue approximation
Serosanguineous fluid
exudate or discharge containing serum and blood
Swage
area of an atraumatic suture where the suture strand is fused to the needle
Tapered needle
suture needle that has a round body that tapers to a sharp point
Tensile strength
amount of force or stress a suture can withstand before breaking
Throw
loop that forms a knot
Tie on a passer
strand of suture material attached to the tip of an instrument
