suture patterns Flashcards
Rules for picking a pattern
- close tissues in same number as you incised
- appostional unless good reason not to
- chose simplest
- avoid tension
- careful suturing mroe important than pattern
5 ways to categorise patterns
1) simple vs mattress
2) interrupted vs continuous
3) appositional vs inverted vs everted
4) partial vs full thickness
5) 1 layer vs 2 layer
what is this pattern and how is it classified?
What is good about it?
what is it used for?
Simple interrupted
appositional, interrupted, full thickness
Good - precise adjustment possible
use - skin, GIT, fascia
what is this pattern?
how is it classified?
intradermal
buried knot, appositional, interrupted
What pattern is this?
how is it classified?
what are the risks?
Modified Gambee
interrupted, appositional
risk of not engaging submucosa
What are the 3 approximating sutures?
simple interrupted
poth and gold crushing
modified gambee
what pattern is this?
how is it classified?
use?
why is it good?
Cruciate mattress
appositional, mattress
strong, prevents eversion, quick,resists tension
skin
What are these 2 patterns
use?
risks?
left = vertical mattress
right = horizontal mattress
skin, muscle, tendon
can strangulate and cause ischaemia if too tight
vertical has better blood supply
What pattern is this?
half buried horizontal mattress
What pattern is this?
why is it used?
mayo mattress / vest over pants
to overlap / tighten tissue plains
imbrication of fascia lata, hernia closure
What pattern is this?
what is it used for?
simple continuous, appositional
sub Q, fascia, vessels, GIT
What pattern is this?
when is it used?
running suture
only for rapid closure
what pattern is this?
when is it used?
subcutaneous continuous
to get good skin closure
What pattern is this?
what is it used for?
ford interlocking
skin
What 2 patterns could this be and what is the difference?
