Flashcards in suturing Deck (8)
What are the suture characteristics?
Tensile Strength: weight required to break a suture.
Knot strength: for required for a knot to slip
Configuration: monfilament, braided multifilament (easier to handle and tie)
Elasticity: degree suture stretches and return to original length.
Memory/suture stiffness: high memory, difficult handling, unties
Tissue reactivity: inflamm response to suture. rxn peaks in 2-7days
Two classes of sutures?
What are the types of sutures in each class?
Absorbable & non-absorbable.
catgut and chromic are natural sutures, the others are synthetic.
What is the absorption rate/ tensil strength of each of the following sutures:
-Tensil strength: 10-14days
-tensil strength: 3-4wks
-tensil strength: 21 days
-tensil strength: 5-6wks
-describe suture sizes
-what areas of the body would you use 2-0 and 5-0?
-range from 5 to 11-0.
the numbers without 0 after them are thicker. 5 is the thickest and 11-0 is the thinnest.
5,4,3,2,1,0, 2-0, 3-0,4-0,5-0,6-0,7-0,8-0,9-0,10-0,11-0.
2-0: drains, chest, abdomen, back
5-0: scalp, brow, oral, chest, abd, hand, nose, lip, face
-after how many days should sutures be removed in each of the following areas:
-delayed wound healing
Scalp: 10 days
Face/ear: 5 daus
*delayed wound healing: 14-21d
The thicker the skin, the longer the sutures remain in the skin.
What are the types needles?
Taper (SH, CT-1, CT-2 are MC)
Trocar point or tapercut
Side cutting or spatula
When would you use blunt taper point?
micropoint spatula cutting?
Blunt taper point = liver
Micro: use on the eye
