single armed double armed permanent swaged controlled release
37
dexon absorption
30 days
38
presence or absence of infection for absorption time
absorption takes place much more rapidly in the presence of infection
39
what is tensile strength?
amount of weight or pull necessary to break the suture of ligature material
40
what is the cutting point used on?
tough connective tissue | SKIN, EYES
41
polypropylene
inert in tissue high tensile strength holds knots well used in infection
42
where is polypropylene used?
cardiovascular, general and plastic
43
most common wire
stainless steel
44
disadvantage of ethilon/dermalon
knots tend to come untied hard to handle surgical nylon
45
advantages of silk
high tensile strength | cheap and easy to sterilize
46
blunt point
dull tip
47
what is a stick tie?
threaded on a needle and used through a bite of tissue as well as on the end of the vessel
48
nonabsorbable suture
this is always removed
49
what is chromic surgical gut treated with?
chromic oxide
50
silk compared to surgical gut
silk has less tissue reaction than surgical gut

not used for infection
54
how should you have needles when they aren't being used?
on needle holder or in needle counter
55
heavy suture needle
used on heavy suture on tough tissue
56
interrupted stitches
each stitch is taken and tied separately and the suture cut
57
advantages of stainless steel

74
what does the ST do when the surgeon is suturing?
threading needle
75
what does a double suture strand cause?
tissue disruption
76

78
nutrition of patient for absorption time
absorbed faster in undernourished
79
eyeless, atraumatic, swaged
new sharp needle with every suture strand
80
halstad technique
many fine interrupted sutures gives firm support to the wound
81
how are curved needle handed to surgeon?
always on needle holder
82
what are suture needles used for?
inserting suture material into tissue
83
how should you hand swaged on needle in needle holder?
never clamp over the end of the needle, it is hollow there and may break from the pressure
