Q

What are the characteristics of a simple interrupted pattern?

A

-maintains strength if one suture fails
-can adjust tension on the wound with each segment
-can use the “halves” method on irregular incisions
-slower
-requires more suture material

Q

What are the characteristics of a cruciate suture?

A

-tension relieving
-allows good tissue apposition
-quicker than simple interrupted
-fewer knots
-useful for skin and fascial plane apposition

Q

What are the characteristics of a vertical mattress suture?

A

-tension relieving
-causes eversion/pulls wound edges up
-placed just below dermis
-overtightening can lead to tissue necrosis
-safer to blood supply compared to horizontal mattress

Q

What are the characteristics of a horizontal mattress suture?

A

-tension relieving
-causes eversion
-placed just below the dermis
-overtightening can compromise local blood supply
-better as a continuous pattern; less damage

Q

What are the general guidelines when placing horizontal mattress sutures in small animal?
