Flashcards in 1-28-2016 Reading Material Deck (41):
1

What determines the type of tissue in which a needle should be used?

the point

2

What is best used in tissue where a sealed suture line is needed?

a taper point needle with a round body

3

What type of needle is used with tough fiberous tissue and some cardiovascular procedures?

a taper-cut needle

4

Which type of needle is the most traumatic to tissue?

a cutting edge needle

5

What three body types may a needle be?

straight, circular, or curved

6

What is one application of the straight needle in veterinary medicine?

purse string suture in anus

7

What three subtypes of curved needles are available?

full curve, half curve or double curve

8

What use are double curved needles usually reserved for?

lare animal surgery especially bovine surgical closures

9

Why are half curved needles classified as such?

only half the needle body is curved

10

Why are full curved needles classified as such?

the entire body of the needle is curved

11

What are four common circular needle shapes?

1/4 circle, 5/8 circle, 1/2 circle, 3/8 circle

12

What is the most common method of suture attachment to the needle?

swaged or eyeless needle

13

What is the purpose of suture material?

to hold together wound edges until the wound can withstand the stress of healing without additional support

14

What are eight characteristics of suture material?

tensile strength, memory, flexibility, absorbability, capillarity, structure, knot security, and color

15

Define tensile strength.

the amount of force in PSI that the suture can withstand as an untied fiber before it breaks

16

Define flexibility.

the ease with which the suture is manipulated either by the surgeon or in the tissue

17

What is the difference between absorbable and nonabsorbable suture?

nonabsorbable suture material is not broken down by the body and can remain intact for at least two years; absorbable suture material is broken down by the body over a period of 60 days - 2 years

18

Define capillarity.

the ability of a suture material to allow microbes to wick to the interior of the suture strand

19

What are the two basic structure types of suture?

monofilament and multifilament

20

Define knot security.

the ability of suture to hold the knots that the surgeon has placed

21

Define natural suture material.

suture made from fibers found in nature

22

Name three natural suture materials.

cotton, silk, catgut

23

Define synthetic suture material.

suture made from manufactured materials

24

Name two synthetic suture materials.

nylon, polyglactin 910

25

What criteria should be considered when selecting suture type and size?

patient size, tissue of placement, strength required, healing potential of tissue, importance of cosmetic appearance, and cost

26

How is suture size classified?

the term "ought" represented by the numeral 0

27

What is the rule for suture sizing classification?

the more zeroes in a size the smaller the suture, the larger whole number the larger the suture

28

What packaging options are available for suture material?

single use sterile packets and cassettes

29

When are external staples a good choice?

when a wound needs to be closed quickly or a patient has a history of chewing a surgical site or tissue reaction to suture material
