Q

What is the purpose of the convex cutting side on reverse cutting needle

A

Minimize cutting of transfixed tissue

17
Q

Which suture type has round needles that have no edges so less likely to cut through tissue

A

Taper

18
Q

What type of tissue is taper needle points used for

A

Abdominal viscera, CT, vessels, other fragile tissue

19
Q

is this appositional, inverting, or everting and what is suture pattern

A

Appositional suture pattern

20
Q

Appositional, inverting, or everting

A

everting

21
Q

Appositional, inverting, or everting

A

Inverting

22
Q

What suture pattern is this

A

Cushing-inverting

23
Q

What do you use Cushing inverting for

A

Closing incisions in hollow viscera such as large colon, urinary bladder, uterus (organs)

24
Q

Where does the needle penetrate in Cushing inverting

A

Submucosa
Does not penetrate lumen of organ

25
Q

What suture pattern is this

A

Connell-inverting

26
Q

Where does the Connell-inverting suture penetrate

A

Passed through submucosa into lumen

27
Q

what suture pattern is this

A

Utrecht-inverting

28
Q

What suture pattern is commonly used to close bovine uterus in C-section

A

Utrecht-inverting

29
Q

What suture pattern is this

A

Interrupted vertical mattress-venting

30
Q

Which suture pattern is commonly used in repairing distal limb lacerations

A

Interrupted vertical mattress-everting

31
Q

Which allows better blood circulation to wound edges: interrupted vertical mattress or horizontal mattress

A

Vertical

32
Q

what suture pattern is this

A

Interrupted horizontal mattress-everting

33
Q

Which suture pattern provides the best tension relief and why

A

Interrupted horizontal mattress- everting because of geometry has tendency to reduce blood supply to wound edges

34
Q

Which suture pattern is best for muscle belly reapposition

A

Interrupted horizontal mattress-everting

35
Q

what suture pattern is this

A

Ford interlocking-appositional

36
Q

In the ford interlocking appositional once the needle is passed through the tissue it is ____

A

Pulled through the loop and tightened “catch the loop”

Simple continuous patterns you do not “catch the loop”

37
Q

what suture pattern is this

A

Near-far-far-near appositional
