7
What are the features of surgical gut?
1. absorbable
2. small intestine of cattle and sheep
3. multifilament
4. formaldehyde treated
5. ionizing radiation
6. not autoclavable
8
What features does surgical gut not fulfill
1. only maintains tensile strength 50% @ 14d
2.picks up moisture (capillary)
3.
4. non-secure knots. Have to leave long tails because picks up moisture
5. minimal reactivity NO
6. phagocytosis so absorption unpredictable unpredictable
7. does not favor bacteria--NO--multifilament
9
What 1 feature does surgical gut fulfill
good handling
10
What 1 feature does surgical gut fulfill
good handling
11
What are the features of polyglycolic acid suture (dexon)
1. multifilament
2. synthetic
3. absorbable
12
What properties does polyglycolic acid fulfill?
1. maintains tensile strength-but short lived (20% @ 14d)
2.
3. good handling--saws tissue
4. secure knots--long tails b/c wiggles
5. minimal reactivity
6. dependable absorption )100-120days)
7.
13
What properties does polyglycolic acid not fulfill?
1. it is not noncapillary (braided)
2. it favours bacterial growth (braided)
14
What are the features of polyglactin 910? (coated vicryl)
1. multifilament
2. synthetic
3. absorbable
15
What properties does polyglactin 910 fulfill?
1. maintains tensile strength (50% @14, 20% @ 21)
2.
3. good handlinng--saws tissue
4. secure knots but make tails long
5. minimal reactivity
6. dependable absorption (40-90 days)
7.
16
What two absorbable multifilament synthetic sutures have very similar properties? What is 1 difference?
1. dexxon (polyglycolic acid)
2. coated vicryl (polyglactin)
coated vicryl absorbed a bit faster than dexxon so then maybe put coated vicryl in area where abcess/infection may occur

18
What two absorbable multifilament synthetic sutures have very similar properties? What is 1 difference?
1. dexxon (polyglycolic acid)
2. coated vicryl (polyglactin)
coated vicryl absorbed a bit faster than dexxon so then maybe put coated vicryl in area where abcess/infection may occur
19

1. absorbable
2. monofilament
3. synthetic
20
What properties does coated vicryl (polyglactin) not fulfil?
capillary
favours growth of bacteria
21
What properties does PDS (polydioxanone) fulfill?
1. maintain tensile strength
22
What properties does PDS (polydioxanone) fulfill?
all of them
1. maintain tensile strength (75% @14d, 58%@4weeks, 14%@8weeks)
2. noncapillary
3. good handling--can kink

23
Why is PDS (polydioxanone) better than vicryl or dexxon?
much better strength retention
noncapillary
doesn't favor bacteria
