Plain suture refers to?
Suture not treated with anything
Chromic suture refers to?
Suture treated with acid salts that delay absorption rate
Capillary refers to what?
- A suture materials ability to absorb liquids
Monofilament suture tends to hold memory more so than multifilament suture. What does this mean?
It retains the shape of the package
What is tensile strength?
How much weight or pull the suture can withstand
What can affect tensile strength?

Knot securuty _________ as suture size _________
Suture sizes range from _____ to ______
When are absorbable sutures used?
When prolonged strength is not required or when infection is present
Non-absorbable suture is used when?
Tissue rxn needs to be minimized or sutures are left in for more than 2 - 3 wks
