Wound closure and sutures Flashcards
1
Q
what are swaged needles?
A
- no eye
- attached by crimping material into hollow end of needed
- less traumatic to tissues
- single use
2
Q
what needle creates more trauma?
A
eyed needles
3
Q
what are the three parts of a needle?
A
- point
- shank
- body
4
Q
what are the various shapes of needles?
A
- round-bodied/taper point
- taper cut
- cutting
- spatulated
- blunt
5
Q
what does appositional mean?
A
Skin edges directly apposed
6
Q
what does everting mean?
A
skin edges are outward - eliminate dead space
7
Q
what does inverting mean?
A
skin edges are inward
8
Q
what are some common suture patterns?
A
- simple interrupted (0.5 cm apart)
- simple continuous
- ford interlocking (interrupted and continuous patterns)
- vertical mattress (interrupted)
- horizontal mattress (interrupted and continuous)
- cruciate mattress
- quilled
9
Q
what is capillarity?
A
how will fluid move along a suture material
10
Q
what is tissue drag?
A
the frictional force as a suture is pulled through tissues
11
Q
what is chatter?
A
the lack of smoothness as a knot is tied
12
Q
what is tensile strength?
A
the amount it can be support when stretched before it breaks
13
Q
what are some categories of suture?
A
- absorbable
- non-absorbable
- natural monofilament
- natural multifilament
- synthetic monofilament
- synthetic multifilament
14
Q
what is monofilament suture?
A
- less drag
- single fibre
- decreased capillary action
- high memory and less knot security
15
Q
what is multifilament suture?
A
- higher capillarity
- creates more tissue drag
- less memory and better knot security
