Q

Three basic components of a needle on the suture?

A

eye/swagged
body
point

17
Q

What is a swaged vs. eyed needle?

A

preloaded, most considered less traumatic, tissue damaged minimal produced

18
Q

Types of suture needle?

A
taper point needle
blunt taper point needle
cutting needle
reverse cutting needle
micro-point spatula needle
19
Q

Shapes of suture needles?

A

1/4 circle, 3/8 circle, 1/2 circle, 5/8 circle, straight

20
Q

What are the two knots used when suturing?

A

square knot, surgeon’s knot

21
Q

What are simple interrupted suture pattern?

A

easy to appy
secure anatomical closure
allows adjustments of suture

22
Q

What are simple interrupted suture pattern used for?

A

skin, SQ tissue, GI, Urinary tract

23
Q

What are the six patterns when suturing?

A

simple interrupted, simple continuous, Far-Far-Near-Near, Far-Near-Near-Far, Interrupted horizontal mattress, interrupted vertical mattress

24
Q

What are simple continuous sutures pattern?

A
  • faster than interrupted suture pattern
  • provides more airtight or fluid tight seal
  • can fail completely if knot is weak or inadequate
25
Q

What are simple continuous suture patturns used for?

A

skin, SQ tissue, Fascia, GI

26
Q

What are far-far-near-near suture pattern?

A
  • variations of vertical mattress

- can provide necessary tension for wound approximation without direct tension to wound edge

27
Q

What are far-far-near-near suture patterns used for?

A

Skin, SQ tissue, fascial closure under tension

28
Q

What are far-near-near-far suture patterns?

A
  • variations of vertical mattress

- can provide necessary tension for wound approximation without direct tension to wound edge

29
Q

What are far-near-near-far suture patterns used for?

A

skin
SQ tissue
Fascial closure under tension

30
Q

What are interrupted horizontal mattress suture patterns?

A
  • can strangulate blood

- appositional to everting suture pattern

31
Q

What are interrupted horizontal mattress suture patterns used for?

A
  • closure in areas of high tension

- flat tension with minimal fascia vessels at wound edges

32
Q

What are interrupted vertical mattress suture patterns?

A
  • appositional to everting
  • stronger in tissue under tension than Horizontal Mattress
  • less likely to occlude small vessels at wound edges
33
Q

What are interrupted vertical mattress suture patterns used for?

A

Closure in areas of high tension

34
Q

A tapered suture needle is used for?

A

suturing subcutaneous tissue, fascia, and other.

35
Q

When suturing a uterine incision in a cow the proper suture size is _____.

A

2

36
Q

What is an inverting suture pattern?

A
Inverting Suture Patterns
- Turn tissue edges 
toward the patient, 
away from the 
surgeon, or toward 
the center of a hollow 
organ
37
Q

When suturing skin, the needle of choice is?

A

A cutting needle is used primarily for suturing the

skin.

38
Q

What are staples?

A

A skin stapler is a medical device that places metal staples across the skin edges to bring the skin together.

39
Q

The main advantage of staples

over sutures is?

A

that they can be placed quickly.
