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

What are simple continuous suture patturns used for?

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

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

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
