> Clamping bleeding vessels
> Clamping a tourniquet
> Substitute needle holder when needed
- Can be straight or curved

Q

What are the different types of suture materials and some typical brands?

A

Non-Absorbable

  • Used to be cotton or silk (caused reactions), but now mostly nylon
  • Nylon is inert, but slippery and difficult to tie and keep tied
  • Nylon is most frequently used to close skin
  • Ethilon brand nylon used in clinic

Absorbable
- Used to be sheep gut, now synthetic polymers
- Vicryl is the most widely used synthetic polymer
- Designed for internal use
> Left in and gets phagocytized
- May cause an immune reaction that can be confused with an infection

  • NUNM mostly uses FS1 needles with Ethilon nylon sutures
