Q

When choosing suture material, what must be considered?

A
  • If infection is a possibility, choosing a suture that can withstand infection.
  • the type of organ being sutured
  • if the area needing to be sutured is a hollow organ - pick sutures that can withstand degradation by intraluminal substances
  • tissues that heal quickly (i.e., stomach) use absorbable sutures
  • tissues that heal slowly (i.e., tendons) use nonabsorbable suture
