Answer 23

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

Question 24

What are simple continuous sutures pattern?

Answer 24

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

Answer 25

skin, SQ tissue, Fascia, GI

Question 26

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

Answer 26

• variations of vertical mattress

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

Question 27

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

Answer 27

Skin, SQ tissue, fascial closure under tension

Question 28

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

Answer 28

• variations of vertical mattress

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

Question 29

Answer 29

skin
SQ tissue
Fascial closure under tension

Question 30

What are interrupted horizontal mattress suture patterns?

Answer 30

• can strangulate blood

- appositional to everting suture pattern

Question 31

What are interrupted horizontal mattress suture patterns used for?

Answer 31

• closure in areas of high tension

- flat tension with minimal fascia vessels at wound edges

Question 32

What are interrupted vertical mattress suture patterns?

Answer 32

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

Question 33

What are interrupted vertical mattress suture patterns used for?
