1

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

2

Two classes of sutures?

What are the types of sutures in each class?

Absorbable & non-absorbable.

Absorbable:
-catgut
-chromic
-vicryl*
-monocryl*
-PDS*

catgut and chromic are natural sutures, the others are synthetic.

Nonabsorbable:
-silk
-nylon
-ethibond
-prolene
-surgical steel

3

What is the absorption rate/ tensil strength of each of the following sutures:
-chromic
-vicryl
-monocryl
-PDS

Chromic:
-absorption: 70days
-Tensil strength: 10-14days

VIcryl:
-absorption: 60-90d
-tensil strength: 3-4wks

Monocryl:
-absorption: 90-119d
-tensil strength: 21 days

PDS:
-absorption: 182-238d
-tensil strength: 5-6wks

4

Sutures:
-describe suture sizes
-what areas of the body would you use 2-0 and 5-0?

Suture size:
-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

5

Suture removal:
-after how many days should sutures be removed in each of the following areas:
-scalp
-face/ear
-chest/abd
-extremities
-penis
-delayed wound healing

Scalp: 10 days

Face/ear: 5 daus

Chest/abd: 8-10d

Extremeities: 10-14

Penis: 8-10

*delayed wound healing: 14-21d

The thicker the skin, the longer the sutures remain in the skin.

6

What are the types needles?

Taper (SH, CT-1, CT-2 are MC)

Cutting

Reverse Cutting

Trocar point or tapercut

Blunt points

Side cutting or spatula

7

When would you use blunt taper point?
micropoint spatula cutting?

Blunt taper point = liver

Micro: use on the eye

8

Advantages of adhesive vs sutures?

CI to use of skin adhesives

Advantages:
-equivalent to strength to healed tissue at seven days post repair
-faster repair time
-water resistant**


CI:
-jagged or stellate lacerations
-bites, punctures, or crush wounds
-mucosal surfaces
-axillae and perineum
-hands, feet, and joints
