flexibility - eas at which suture is manupulated
absorability- can be broken down by body from 7 days to 2yrs
Capillarity- allow microbes to wick to interior of strand
structure Multifiliment - 2 or more strands braided together
Monofilament - single sloid
knot security
color
origion of material

broad spectrum
nonirritating
nontoxic
noncorrosive inexpensive

Front 17

ideal suture material

Back 17

non-reactive
easy to handle monofilament easy to sterilize
high knot strength
lack of memory
absorbs in a predictable manner
economical

Front 18

effectiveness depends on

Back 18

type of microorganism
degree of contamination
amount of protein in area
organic matter
additional sanitizing compounds
concentration and quality of chemicle
contact time and temp

Front 19

Sizes of sutures

Back 19

fine to course 2, 1, 0(ought) 2-0 3-0 4-0 (9-0 is finest)
000 is 4-0 the more zero's the smaller the suture

Front 20

Types of Disinfectants

Back 20

Chlorine based - bleach cleaning & disinfecting deactivated by fecal matter
Phenol based - Lysol-pinesol -toxic to cats works in presence of organic material
quaternary amine based - roccal-d plus-binds to and inactivated by organic material
Iodine - providone iodine used as antiseptics- inactivated by organic material
Cholrhexidine- used widely for tables and instruments- works in presence of organic material, must have contact time to be effective

Front 21

Surgifcal Gut (cat gut) - Chromic acid treated

Back 21

plain gut absorbed in 3-5 days chromic gut 10-15 days
easy to handle ties well good knot security economical
hygoscopic(swells), tissue reaction, strong capillary action microbes migrate to middle of strand

Front 22

PGA polyglycolic acid (Dexon)

Back 22

synthetic suture made in fine threads then woven into suture- retains strength 2-3 weeks, handles well low reaction- know slippage high tissue drag

Front 23

Suture needles

Back 23

Point - Taper point sharp point rounded used for intestines or other hollow organs
taper cut - round body and reverse cutting point used for tough fibrous tissue and cardio
reverse cutting
cutting - most traumatic

Front 24

PLA polygalactia 910(vicryl or Polymend)

Back 24

similar to PGA
braided or monofilament - retains strength 3 wks; absorbs in 90 days

Front 25

Needle body - straight circular or curved

Back 25

shape- 5/8 circle, 1/2 circle 3/8, 1/2 curve 1/4 circle straight

Front 26

PDS polydioxanone(monomend)

Back 26

Synthetic monofilament longest lasting absorbable suture available, low tissue drag good retention of strength monofilament long lasting - expensive high memory known slippage

Front 27

attachment -

Back 27

single eyed pass from inside curve to outside
french eyed one complete eye and one split
swaged(eyeless) most atraumatic

Front 28

Nonabsorbable suture material - remains in tissue until removed if buried becomes encysted

Back 28

Silk and cotton
Braided synthetics
monofilament synthetics metal
silk used in cardiovascular and ophthalmic surgery

Front 29

needle size

Back 29

the lower the # the larger the needle (flyhooks)

Front 30

Suture Sterilization

Back 30

autoclaving- destroys gut PDS PLA and PGA - decreases strenght of nylon polyester prolypropyleme- safe for metal
Radiation - safe for all suture material
Ethylene Oxide safe and effective for all suture

Front 31

Suture Patterns -

Back 31

Interrupted - sutures that are tied or cut after one or two passages through the tissue - maintains strenght technique easy and rapid uses more material takes more time increase forien body
Continuous - a pattern has multiple passages knot at each end- easy miinimal material easy to remove mor rapid closure - entire line breaks if one component fails

Front 32

subcutaneous sutures

Back 32

Dr Tank Uses - simple interrupted or continuous pattern wied to close the fat layer below the skin

Front 33

Factors affecting the healing process

Back 33

nutrition - protein deficency and anemia retard the healing process
steroids reduce inflammation but also delay healing

Front 34

Healing process - wound healing befins when tissue is damaged
goal to restore the injured tissue to its prewound condition in a short time wiht minimal loss of function

Back 34

1 Inflammatory phase
debridment
repair
maturation

Front 35

Golden period - first 6 hrs

Back 35

after this period a contaminated wound is considered infected

Front 36

Exudative phase- passage of fluid and cells into tissues or cavities -Inflammatory response

Back 36

redness
swelling
heat
loss of function
pain

Front 37

1st intention healing

Back 37

immediate cleaning and suturing - clean wounds less than 6 hrs uncomplicated lease scarring

Front 38

Collagen phase (repair phase)

Back 38

collagen major protein that binds cells and tussue together- granulation and new capillaries are formed

Front 39

2nd intention - leave alone

3rd attention wound begins to hean then is sutured Intermediate scarring

Back 39

healing through granulation - most scarring

Front 40

Maturation phase Scarring happens

Back 40

the wound is covered with epitheliun - contraction occurs
