Suture Lecture Flashcards
What is suturing?
the act of joining two surfaces together with a stitch or a series of stitches
What is the goal of suturing?
to hold wound edges in apposition to one another until the tissue has sufficient time to heal
Suturing is a?
learned skill
Personal preference plays a role in the?
type
What are the instruments needed for suturing?
Adson-Brown thumb forceps,
Suture scissors, Mayo-Hegar needle holder, or Olsen-Hegar needle holder
Straight or curved standard scissors
What are the three choices of suture materials?
absorbable or nonabsorbable
natural or synthetic
braided (multifilament) or monofilament
What are absorbable sutures?
designed to breakdown over a specific time frame and absorbed by body, 60 days
What are nonabsorbable sutures?
designed to either be left permanently in the body or removed after a certain healing period, 180 days
What is monofilament sutures?
- construction result of a single strand or filament
- surface is very smooth and passes through tissue easily
- memory
What is multifilament sutures?
- memory
- several filaments or strands being braided or twisted together
- strong, flexible and easy to handle
What are natural sutures?
- made from animal or plant material
- protein composition
- strength tissue varies from a few days (Plain Catgut) to several months (silk)
What are synthetic sutures?
- predictible degradability
- less tissue reaction
What is the different suture sizing?
7 heaviest to 11-0 finest
suture only
Suture only need _____ or slightly exceed the _____ power for wound.
match
holding
Ex: your shoes need to tie.. a rope would work but its overkill. A shoe lace will ite and hold yours shoes on your feef
Small knots, means ____ ____ reaction and minimal _____.
less tissue
scar
Three basic components of a needle on the suture?
eye/swagged
body
point
What is a swaged vs. eyed needle?
preloaded, most considered less traumatic, tissue damaged minimal produced
Types of suture needle?
taper point needle blunt taper point needle cutting needle reverse cutting needle micro-point spatula needle
Shapes of suture needles?
1/4 circle, 3/8 circle, 1/2 circle, 5/8 circle, straight
What are the two knots used when suturing?
square knot, surgeon’s knot
What are simple interrupted suture pattern?
easy to appy
secure anatomical closure
allows adjustments of suture
What are simple interrupted suture pattern used for?
skin, SQ tissue, GI, Urinary tract
What are the six patterns when suturing?
simple interrupted, simple continuous, Far-Far-Near-Near, Far-Near-Near-Far, Interrupted horizontal mattress, interrupted vertical mattress
What are simple continuous sutures pattern?
- faster than interrupted suture pattern
- provides more airtight or fluid tight seal
- can fail completely if knot is weak or inadequate
What are simple continuous suture patturns used for?
skin, SQ tissue, Fascia, GI
What are far-far-near-near suture pattern?
- variations of vertical mattress
- can provide necessary tension for wound approximation without direct tension to wound edge
What are far-far-near-near suture patterns used for?
Skin, SQ tissue, fascial closure under tension
What are far-near-near-far suture patterns?
- variations of vertical mattress
- can provide necessary tension for wound approximation without direct tension to wound edge
What are far-near-near-far suture patterns used for?
skin
SQ tissue
Fascial closure under tension
What are interrupted horizontal mattress suture patterns?
- can strangulate blood
- appositional to everting suture pattern
What are interrupted horizontal mattress suture patterns used for?
- closure in areas of high tension
- flat tension with minimal fascia vessels at wound edges
What are interrupted vertical mattress suture patterns?
- appositional to everting
- stronger in tissue under tension than Horizontal Mattress
- less likely to occlude small vessels at wound edges
What are interrupted vertical mattress suture patterns used for?
Closure in areas of high tension
A tapered suture needle is used for?
suturing subcutaneous tissue, fascia, and other.
When suturing a uterine incision in a cow the proper suture size is _____.
2
What is an inverting suture pattern?
Inverting Suture Patterns - Turn tissue edges toward the patient, away from the surgeon, or toward the center of a hollow organ
When suturing skin, the needle of choice is?
A cutting needle is used primarily for suturing the
skin.
What are staples?
A skin stapler is a medical device that places metal staples across the skin edges to bring the skin together.
The main advantage of staples
over sutures is?
that they can be placed quickly.
