suture patterns

Question 1

buried knot

Answer 1

knot below skin in SQ
can be simple interrupted or cruciate suture
“deep superficial superficial deep”

Question 2

interrupted suture patterns
pros:
cons:

Answer 2

pros: ease of placement, adjustable tension, loss of knot less disastrous, strenght, tissue mobility

cons: more time/material

Question 3

types of interrupted suture patterns

Answer 3

simple interrupted
cruciate
horizontal mattress
vertical mattress
far-far-near-near (pulley)
far-near-near-far (pulley)

Question 4

when would you use a cruciate suture? how is its tension?

Answer 4

skin
body wall closure

appositional moderate tension suture

Question 5

when would you use a horizontal mattress? how is its tension?

Answer 5

skin, fascia
tension-relieving (w/ buttons, rubber tubing)
may interfere with blood supply to skin edge

Question 6

when would you use a vertical mattress? how is its tension?

Answer 6

skin, fascia
apposition-slight eversion, tension relieving suture (w/ buttons, rubber tubing)

Question 7

when to use pulley sutures?

Answer 7

tension relieving
all forehand bites

Question 8

continuous suture patterns
pros:
cons:

Answer 8

pros: speed, less material, easy removal, better initial seal

cons: lots of knots, breakage, more disastrous

Question 9

when to use a simple continuous pattern?

what is a con to simple continuous?

Answer 9

any tissue where apposition is desired
minimal-mod tension
use if a good seal is desired

con: too tight will necrose, invert or evert or wrinkle

Question 10

where is an intradermal suture placed? what is required?

Answer 10

in the dermis “subcuticular”

begin with a buried interrupted knot, pass suture parallel to incision, absorbable suture, cutting needle

Question 11

what is needed for a subcutaneous suture

Answer 11

absorbable suture
taper needle (or cutting)

Question 12

what is needed for a cutaneous suture

Answer 12

non-absorbable suture
cutting needle

Question 13

when to use a Cushing/Connell inverting suture pattern

Answer 13

closing hollow viscera
suture passed parallel to incision
cushing - partial thickness
connell - full thickness “L into Lumen”

Question 14

when to use a Lembert inverting suture pattern

Answer 14

closure of hollow viscous
second-layer
suture passed perpendicular to incision
partial thickness

Question 15

when is ford interlocking used?

Answer 15

skin
not common in small animals
