1

adhesion

abnormal attachment of two surfaces or structures that are normally separate

2

anastomosis

pathological, surgical, or traumatic formation of an opening between two normally separate organs or spaces

3

approximated

returned to proximity; brought together sides or edges

4

autologous

from oneself

5

capillarity

capability of multifilament suture to harbor bacteria and retain tissue fluid that can travel down the length of the suture strand

6

chronic wounds

wound that persists for an extended period of time

7

cicatrix

scar

8

collagen

protein that consists of bundles of reticular fibers that form the white. inelastic fibers of facia, ligaments and tendons

9

compress

to apply pressure

10

dead space

a space that remains in the tissues as a result of failure of proper closure of a surgical wound

11

debridement

removal of devitalized tissue and contaminants

12

dehiscence

partial or total separation of a layer or layers of tissue after closure of the wound

13

edema

the abnormal accumulation of fluid in the interstitial spaces of tissues causing swelling

14

elasticity

the ability of tissue such as skin, lungs, or muscles to return to its normal shape after being pushed

15

evisceration

interruption of a closed wound or traumatic injury that exposes the viscera

16

exudate

fluids or other substances that are discharged from cells or blood vessels; examples are perspiration and pus

17

first intention

type of healing that occurs with primary union that is typical of an incision opened under ideal conditions; healing occurs from side to side, dead space has been eliminated, and the wound edges are accurately approximated

18

french-eyed needle

a type of needle in which the suture must be threaded by pulling the strand through a V-shaped area into the eye

19

friable

easily torn or crumbled

20

gangrene

necrosis of tissue usually due to ischemia and subsequent bacterial infection

21

granulation

second intention wound healing in which the wound is left open to heal and the space is filled in from the bottom upward with granulation tissue

22

granuloma

small inflamed area in tissue usually the result of an infection and often occur in the lungs

23

hematoma

localized collection of extravasated blood that is often clotted

24

hemolysis

the destruction of erythrocytes

25

hemostasis

the arrest of the escape of blood through natural or artificial means

26

hemostat

an instrument used to grasp tissue on vessels or clamp onto a vessel

27

herniation

abnormal protrusion of an organ or other body structure through an opening in a covering membrane or muscle

28

homologous

from the same species

29

immunosuppressed patient

patient whose immune system has decreased due to disease, or intentionally decreased with immunosuppressive drugs from organ transplant patients to prevent organ rejection

30

inert

a substance, such as the aiming beam of a laser, that is inactive and has no effect on tissue

31

inflammation

the body's protective response to injury or tissue destruction

32

ischemia

lack of oxygenated blood supply to an area or organ of the body

33

keloid

complication of wound healing resulting in hypertrophic scar formation

34

laceration

cut or tear

35

ligated

the placement of a suture tie around a vessel or other anatomical structure for the purpose of constriction (i.e., to control hemorrhage from a blood vessel)

36

memory

the ability of a material to return to its former shape after being moved or manipulated

37

monofilament suture

suture that is manufactured from one strand of natural or synthetic material

38

packing

sterile fine-mesh gauze that is loosely placed in a chronic wound or one that has been left open to heal by second intention

39

pliability

the flexibility and/or how easily a material can be bent

40

primary suture line

main suture that approximates the wound edges for first intention healing to occur

41

PTFE

a synthetic coating used on certain types of nylon suture material to reduce the drag through tissue

42

Rh(Rhesus) factor

genetically determined blood group antigen that is present on the surface of erythrocytes of some individuals; if the antigen is present the individual is Rh+ (positive) and if absent Rh- (negative)

43

second intention

healing that occurs when a wound fails to heal by primary union, or the wound is left open and allowed to heal from the inside to the outside by filling with granulation tissue

44

secondary suture line

sutures placed to support and ease the tension on the primary suture line, thus reinforcing the wound closure and obliterating any dead space

45

seroma

swelling within a tissue or organ caused by the localized accumulation of serum

46

serosanguinous

fluid that contains both blood and serum

47

swaged

strand of suture material with an eyeless needle attached by the manufacturer; the needle is continuous with the suture strand

48

synthetic

material that is man-made such as synthetic sutures

49

tensile strength

amount of pull or tension that a suture strand will withstand before breaking; expressed in pounds

50

third intention

healing that occurs when two granulated surfaces are approximated; also referred to as delayed primary closure

51

tissue reaction

abnormal response of tissue to foreign substances such as suture material

52

vessel loops

thin strips made of silicone that can be placed around a vessel, nerve, or duct for the purposes of retracting or isolating; the loops are colored for easy identification of retracted structures

53

wound disruption

general term for the various types of abnormal separation of a surgical wound such as dehiscence and evisceration

54

incision

a surgical cut made in skin or flesh

55

contusion

a region of injured tissue or skin in which blood capillaries have been ruptured, a bruise

56

abrasion

the process of scraping or wearing something away

57

hydrolysis

the chemical breakdown of a compound due to reaction with water
