25
what happens if non absorbable are left in skin
may get encysted
26
when should non absorbable be removed
7-14 days post op
27
forms due to a pocket of dead space or unrestricted exercise with sutures
seroma
28
splitting open of part of surgical wound due to licking or chewing
dehiscence
29
licking or chewing completely through body wall
complete dehiscence
30
non-absorbable: excellent handeling, commonly used in cardiovascular surgery, can induce severe soft-tissue reaction, can serve as point of origin for infection
silk
31
non-absorbable: natural fibers, strengthen when wet, behaves like silk, limited use
cotton and linen
32
non-absorbable: synthetic, no tissue reaction, strength lasts 7 years, stiff and slippery, significant memory, excellent handling
polyamide
33
non-absorbable: synthetic plastic, similar to nylon, does not weaken over time, permenent suture support
polypropylene
34
non-absorbable: elastic, useful for ligament repair and structures under weighted motion
polybutester
35
non-absorbable: multifilament, requires 5-6 knot throws, significant tissue drag and reaction, may have teflon or silicone coating, may cause chronic infection and draining fistuale
polyester fiber
36
non-absorbable: coated with plastic-like material, high tensile strength, minimal tissue reaction, outer sheath can break, should never be used below skin level, can predispose fistulas
polymerized caprolactum
37
what can polymerized caprolactum cause if left in too long
stitch granuloma
38
useful in infected wounds or tissue that will be stressed in a slow healing process, also active and chewing pts
wire
39
#5 string
ordinary
40
#0 string

41
#10-0
very delicate sx
42
what do needles vary in
shape, point design, attatchment, size
43
needle frequently used and reusable with any type of point, but must thread through eye and causes possible tissue damage
eyed needles
44
needle will not unthread itself, less bulky, always sharp, material attached, but more expensive and one time use
swaged or swedged
45
what needle is most atraumatic
swaged or swedged
46
stapler has squeeze trigger, holds 25-35 staples, places single row, used for skin and fascia closure, cannot refill
surgical skin stapler
47
stapler one time use, GI resection and anastomosis, 4 rows of staples and cuts between middle 2 rows, pre packaged
gastrointestinal stapler
48
stapler comes pre packaged, used in lung resection, places double or triple row of staples
thoracoabdominal stapler
49
stapler used for blood vessel ligation, places 2 staples on a vessel and cuts between them
ligate-and-divide stapler
50
needle driven through by hand, resembles regular sewing needle; aka keith needle
straight
51
special needle with the eye in the point, requires a special braided tubular suture, used for retaining prolapsed vaginas in large animals
buhner needle
52
needle with double curve design, goes through skin without wrist pivot, only used in large animal; aka bovine needle
s curve
53
needle uses holders to drive through tissue, many different curvatures, hundreds of types
curved
54
when is a curved 1/4 circle used
opthalmic sx
55
when is a curved 3/8 & 1/2 circle used
general sx (most popular)
56
needle round all the way to the tip with taper, used for soft tissue, internal tissues, and SQ, atraumatic to tissues
non-cutting or tapered
57
needle produces "cut out" effect, should not be used with an airtight or watertight suture line, used for skin and tough tissue, triangular shapped point
cutting
58
needle where triangle is reversed, has less cut out, does not bend as easily most preferred
reverse cutting
59
K needle aka
reverse cutting
60
how are suture patterns categorized
continuous or interrupted
61
how are suture pattern catagories divided
simple and mattress
62
suture pattern designed to withstand added tension
mattress
63
turning tissue outward toward surgon; will not close
everting
64
turning tissue inward toward patient
inverting
65
brings tissue in direct apposition
apposing
66
how many throws are used for suturing
2-4
67
where are needle holders held
inside of sutures
68
suture pattern used in skin, SQ, fascia, blood vessels, GI, causes puckering and strangulation
simple continuous
69
suture pattern used in skin, SQ, fascia, blood vessels, nerves, GI
simple interrupted
70
suture pattern used in skin and fascia, stronger closure, resists tension, faster to apply
interrupted cruciate
71
suture pattern used on skin and diaphragm, mainly used in large animal
ford interlocking
72
suture pattern used in skin, SQ, fascia, muscle, tendon, continuous is common in cattle following rumenotomy, potential for strangulation
horizontal mattress
73
suture pattern used for inversion of visceral stumps or tubes
purse string
74
suture pattern used for manipulation or retraction of tissue, usually 2 or more are used
stay sutures
75
suture pattern where suture material is passed through the stump to ligate, tied around half the stump, then around entire stump
transfixation ligature
76
suture pattern for closing gut, needle penetrates serosa and musculans but not mucosa, continuous or interupted
lembert
