Vicryl
26

27
Part of the needle that meets the thread.
Eye
28
Thinnest part of the needle.
Eye
29
Where to grab the needle.
As close to the swaged end as possible, without touching the swaged end.
30
Eye is AKA?
Swaged end
31
Advantage of reverse cutting needles.
Less likely to avulse the tissue.
32
This shape needle is good for passing between nasal nares.
Straight
33
Finger used to control the needle driver.
Index finger
34
How many throws make a knot?
2
35
How many throws make 1.5 knots?
3 throws This is BAD!
36
How many throws make two knots?
4 throws
37
A space formed between tissues that are normally connected.
Dead space
38
Why do we try to avoid dead spaces in sutures?
Because a clot will form there, constricting blood supply to the tissues.
39
Type of suture used from going onto the skin (like from the vermillion border to skin).
Prolene to look pretty
40
Type of suture used if going from vermillion to mucosa.
Chromic or plain gut.
41
A single stitch is called what?
Interrupted suture
42
How do you close a wound?
In LAYERS! To prevent hematoma formation.
43
Suture type for deeper layers.
Resorbable
44
Suture type for skin closure (supfericial layers)
Non-resorbable.
45
After how many days do you remove non-resorbable sutures and why?
5-7 days bc you can get increased scar formation since the epithelial cells keep depositing at the wound margins.
46
A wound in the mouth is closed from the inside or outside first?
Inside bc the mouth has a lot of bacteria.
47
Must be done to the margins so you get nice healing.
Evert the margins

Tension-free
50

Resorbable
51
May necesssitate removal of the affected part of the wound.
End circulation wounds bc they don't get enough blood supply.
52
Closure in which no sutures are placed.
Secondary
53
Closure used when: 1) The extent of the wound is unclear. 2) Avulsion would make primary closure difficult. 3) Avulsion prevents primary closure.
Secondary closure
54
Secondary closure is AKA what?
Delayed
