Confined locations or deep tissue

34
Q

___ circle suture needs are utilized most commonly.

35
Q

What are the two types of suture attachments and what are features of each?

A

Swaged (eyeless) - single use, less tissue trauma

Nonswaged (eye) - closed eye or ridge slit, reusable (needle dulls), suture attachment > needle width. More traumatic to tissues

36
Q

What are the features of taperpoint suture needles?

A

Fine point that spreads tissue during passage.

Used in intestines, SQ, bladder.

NOT used for skin

Dissects through friable tissue without cutting (liver, spleen)

38
Q

What are the features of cutting suture needles?

A

Cutting surface on the concave side of the needle - increases risk of “pull through”

39
Q

What are the features of reverse cutting suture needles?

A

Cutting surface on the convex side (less risk of pull through = less trauma to tissues)

Used for skin.
