vt15c quiz study guide 2 surgicall assisting, sutures, and suturing

Question 1

multifilament sutures

Answer 1

high flexibility; handles well
low memory; less likely to spontaneously untie
high capillarity; not used in skin or holow organs
greater surface friction;greater trauma to tissues

Question 2

monofilament sutures

Answer 2

less flexibility; not as easily handled
greater memory; more likely to spontaneously untie
low capillarity; may be used with any tissue
low surface friction; less trauma to tissues

Question 3

suture sizes

Answer 3

increased suture size decreased knot security

oversized suture ; increased trauma

Question 4

synthetic absorbable broken down by hyrdolysis

Answer 4

polyglactin (Vicryl), polydioxanone (PDS), polyglycolic (Dexon)

Question 5

synthetic non absorbable tensile strength 180 + days loses over years

Answer 5

monofilament nylon (Ethilon), polypropylene (Prolene), polyester (Ethibond), polymerized caprolactum (Braunamid)

Question 6

other sutures

Answer 6

stainless steel , staples, tissue adhesive

Question 7

polyglactin (Vicryl)

Answer 7

coated multifilament, very little memory

Question 8

polydioxanone (PDS)

Answer 8

monofilament, high memory

Question 9

polyglycolic (Dexon)

Answer 9

cotaed or not coated multifilament, very ;little memory

Question 10

Ethilon , nylon

Answer 10

commonly used on skin

Question 11

polypropylene (Prolene)

Answer 11

doesnt loose tensile strength, stretches without breaking

Question 12

polyester (Ethibond)

Answer 12

coated or non coated multifilament

Question 13

polymerized caprolactum (Braunamid)

Answer 13

coated multifilament , high tensile strength, provide on large spool only used on skin

Question 14

steel wire

Answer 14

non absorbable radiopaque very high tensile strength lowest risk of tissue infection

Question 15

taper point needle

Answer 15

spreads tissue aprt, creates water proof seal, less hemorrhage, used with hollow organs

Question 16

cutting needle

Answer 16

creates a hole larger than suture material , passes througoh tissue easily , most traumatic, cutting edge toward edge of wound, avoid with fryable delicate tissue

Question 17

reverse cutting needle

Answer 17

create hole larger than suture material, passes througho tissue easily, less traumatic, cutting edge away from edge of wound

Question 18

attachments

Answer 18

single eyed, french or split eyes;one complete eye and one incomplete eye, swaged or atraumatic; suture is atached to end of needle during manufacturing

Question 19

threading the needle `

Answer 19

never double thread, thread from inside of curve, pull 10 cm through eye
french eyed; thread through complete eye, pull down through split eye

Question 20

interrupted suture pattern

Answer 20

knot tied at each suture, achieve beter apposition(edges of wound brought in) less risk of infectionand of dehisancr takes longer to place, use more material

Question 21

continuous suture pattern

Answer 21

knot at beginning and end of suture, greater risk of infection and dehiscence, quicker application, use less material

Question 22

appositional patterns

Answer 22

side by side

Question 23

everting pattern

Answer 23

turns wound edged outwards

Question 24

inverting patterns

Answer 24

wound edges inward

Question 25

tension

Answer 25

better distribute tension to wound

Question 26

suture placement

Answer 26

hold needle in dominantn hand thumb forceps in non dimant. grasp tissue with forceps, push needle through cutaneous layer, facing toward incision, entering from above, on opposite side of incisionl enter from below, push needle through, pull through and tie

Question 27

square knot

Answer 27

commonly used, joinign 2 strands

Question 28

suture size areas

Answer 28

chest 6, abdomen 1, skin 3-0, blood vessels 5-0,7-0

eye surgeru 8-0,10-0
