Q

Swage

A

Area of an atraumatic suture when the suture strand is fused to the needle

22
Q

Tapered needle

A

Suture needle that has a round body that tapers to a sharp point

23
Q

Tensile strength

A

Amount of force or stress a suture can withstand before breaking

24
Q

Throw

A

Loop that forms a knot

25
Q

Tie on a passer

A

Strand of suture material attached to the tip of an instrument

26
Q

Thrombin

A

Active hemostasis for topical use in bleeding tissues; bovine or human origin

27
Q

Gel foam

A

Mechanical hemostatic on tissue surface or vascular anastomosis; Dry sponge or film material derived from porcine tissue

28
Q

Surgicel

A

Mechanical hemostasis; oxidized cellulose hemostat; swells on contact with fluid; absorbs in 1 - 6 weeks

29
Q

Tisseel

A

Gel; fibrin combination sealant; low bonding strength; requires 20 minutes prep time; used to seal lung, liver, plastic sx, skin grafting; prevents air leaks; capillary hemostasis

30
Q

Floseal

A

Fibrin combination sealant; gel; flowable topical hemostat; bovine-derived gelatin matrix, human thrombin in calcium chloride soln; resorbed in 6 - 8 weeks

31
Q

Dermabond

A

Fibrin combination sealant; liquid; used to close the skin (incisions and lacerations); synthetic cyanoacrylate; fast setting with high strength; nonabsorbable

32
Q

Silver nitrate

A

Fluid or applicator; creates thick eschar (scab); stains tissue; caustic chemical; seldom used; used only for superficial bleeding

33
Q

4X4 Raytec sponge

A

Large square of loosely woven gauze folded into 4 inch square pad

34
Q

Laparotomy sponge

A

Lap or tape; use in major sx; used to absorb blood and fluids for padding beneath the blades of large retractors

35
Q

Sponge dissector

A

Peanut, pusher; Small round or oval sponge covered with gauze; Always mounted on a clamp and used to separate or for blunt dissection

36
Q

Round sponge

A

Tonsil sponge; covered with gauze and has a string attached for retrieval

37
Q

Flat neurosurgical sponge

A

Cottoned or patty; compressed square of synthetic or cotton material with a string attached; used to maintain hemostasis or as filter over delicate tissue requiring suction

38
Q

Flat dressings

A

Most common and simplest type of surgical wound dressings; thin, nonstick pad covered by 1 or 2 layers of flat gauze secured with tape

39
Q

Rolled dressings

A

Used for wrapping a limb; may be plain gauze or an elasticized material; Kling, elastoplast, tube stockinet

40
Q

Gauze packing

A

Used in a cavity (nose, open wound); long, thin strip and packaged in bottle or similar container; usually removed early in recover period (source of infection)

41
Q

Steri-strips

A

Used to approximate small incisions and protect the wound; Used in minor sx and for minor wounds

42
Q

Secondary intention

A

Wound not sutures; heals from base; healing process involves filling tissue gap with granulation tissue; slower than primary intention, results with scar; required for infected or grossly contaminated wounds

43
Q

Third intention (delayed closure)

A

Process in which and infected or a contaminated wound is treated and wound space is packed to prevent serum accumulation and protect against environmental exposure; when sufficient granulation tissue has filled in wound, it is sutured

44
Q

Clean wound

A

Uninfected; closed primarily (all tissue layer sutured closed); no inflammation; may contain closed drainage system; rest, go, genital, and uninfected urinary tracts not entered; 1%-5% risk of post op infection

45
Q

Clean contaminated wound

A

No evidence of infection or major break in aseptic tech; resp, go, genital, or urinary tracts were entered w/o unusual contamination; 3% - 7% risk of post op infection

46
Q

Contaminated wound

A

Open, fresh, accidental wound; gross spillage from go tract occurred; presence of acute, non purulent inflammation; major break in aseptic tech; 10%-17% risk of post op infection

47
Q

Dirty or infected wound

A

Old traumatic wounds with devitalized tissue; existing clinical infection; perforated viscera; >27% risk of post op infection

48
Q

Inflammatory phase

A

Begins as soon as tissue is injured; phagocytes migrate to wound site and digest excess fibrin, bacteria, and cell fragments; usually takes 3- 4 days

49
Q

Proliferative phase

A

Begins about day 4 or 5 and continues for approx. 2 weeks; granulation tissue forms

50
Q

Remodeling

A

Last stage of wound repair; begins after approx. 3 weeks, lasts 22 days - 1 year
