Needles, Suture Patterns, and Knots Flashcards
1
Q
Swaged Needles
A
- needle already attached to suture
- less traumatic
- needle of choice
2
Q
Eyed Needles
A
- reusable: saves money
- get dull
3
Q
Simple interrupted suture pattern
A
- Advantages
- adjustable tension at each suture
- can maintain closure despite 1 suture failure
- cosmetic and precise
- Disadvantages
- Time consuming
- Inc foreign material if buried in wound
- Inc cost
4
Q
Interrupted Subcuticular
A
- buried knot, more cosmetic
- can use continuous pattern
5
Q
Tension relieving suture patterns
A
- Cruciate
- Horizontal mattress
- Vertical mattress
- Far-Near-Near-Far
6
Q
Horizontal Mattress
A
- Everts tissue some
- Used in areas of tension
7
Q
A
Horizontal Mattress
8
Q
Cruciate suture
A
- Appositional suture
- can relieve low to moderate tension
9
Q
A
Cruciate suture
10
Q
Vertical Mattress
A
- Far - far - near - near
- less likely to evert tissue than horizontal mattress
- stronger than horizontal mattress when used in areas of tension
11
Q
A
Vertical Mattress
12
Q
A
- Far - Near - Near - Far
- Excessive tightening will result in an inversion
- Tension relieving
13
Q
Layers of intestine
A
Outside-in
- Serosa
- Longitudinal Muscle layer
- Circular Muscle layer
- Myenteric Plexus
- Submucosa
- Submucosal Plexus
- Muscularis Mucosa
- Mucosa
14
Q
Gambee Pattern
A
- used in intestinal surgery to reduce mucosal eversion
15
Q
A
Gambee pattern
16
Q
Continuous Patterns
Advantages/Disadvantages
A
- Advantages
- Rapidly placed
- Air or water tight seal
- Less suture material
- Disadvantage
- breakage or knot slippage will cause failure
- Knot is weakest point of suture line
17
Q
A
Simple Continuous pattern
18
Q
Ford Interlocking Pattern
A
- Modification of simple continuous
- locked patterns: may appose tissue better, placed quickly
- uses more suture
19
Q
A
Ford Interlocking Pattern
20
Q
Lembert Pattern
A
- Inverting pattern
- modification of vertical mattress
- Prof uses for stomach after closing mucosa
21
Q
A
Lembert Pattern
22
Q
Connell and Cushing Patterns
A
- Inverting patterns for closing hollow organs
- stomach, bladder, uterus, etc
- helps create water tight seal
- Connel: enters lumen
23
Q
A
Connell Pattern
24
Q
A
Cushing pattern
25
Knots
