longitudinal; cross
26
what is a kelly or crile hemostat used for
clamping smaller pedicles
27
how do you tell a kelly from a crile
kelly 1/2 striated; crile full length
28

smaller; lower; larger; greater
31
what is one example of eyed suture
cat gut
32

swaged
33
absorbable suture
loses significant tensile strength within 60 days of implantation
34
non-absorbable suture
retains 100% of tensile strength for at least 60 days
35
how are natural fibers absorbed
collegenases or elastases (enzymatic digestion)
36
how are synthetic fibers absorbed
hydrolysis
37
what influences speed of suture absorption
suture, patient, environment
38
does PDS or monocril absorb faster
Monocril
39
what should guide your decision when choosing a suture
the speed in which the tissue will heal (ex. soft tissue vs tendons)
40

6-7 weeks
42
what type of suture would you use on tendon injuries
non-absorbable
43
intestine takes how long to heal

what is a factor to consider when choosing suture for the stomach
takes only 2 weeks to heal BUT also low pH
45
when do you use knotless barbed suture
minimally invasive surgery
46
why might you use coated sutures
improved pliability, knot formation, reduced drag, reduced risk of infection
47
T/F good quality suture has a lot of memory
F; it should have little memory

T
61
when are skin sutures typically removed
10-14 days post-op
62
when are staples used

what is used for spay/neuter ligations at OVC
PDS or Monocryl
65
what is used to suture skin at OVC
prolene (or staples if good patient and long anaesthetic time)
66
what should you use for hollow viscera
PDS (Monocryl if bladder)
67
What should you use for intradermal or sub q suturing
Monocryl

to remove memory from suture, where should you hold
suture (NOT the needle as it may come off)
69
apposing suturing is used for (2)
skin, intestine
70
inverting suturing is used for (2)
bladder, stomach
71
