suture/sx things

Question 1

main use of chromic gut

Answer 1

ligation of small vessels, gingiva. cheap

Question 2

which holds tensile strength more: monocryl or vicryl. which causes more tissue drag?

Answer 2

monocryl lasts for 1 week. vicryl lasts for 2-3 weeks. vicryl has increased tissue drag

Question 3

which absorbables are okay in contaminated wounds

Answer 3

PDS, monocryl

Question 4

nonabsorbable with high tensile strength but high reactivity to tissues

Answer 4

silk. lasts 12 weeks tensile strength because braided polyfilament

Question 5

nonabsorbable. lacks tissue reactivity. least thrombogenic. lots of memory

Answer 5

proplene (polyproplene)

Question 6

what is proplene used for

Answer 6

tendons, ligaments, joint capsules and fascia

Question 7

what has better handling and lower memory. it also has antibacterial by products. non absorbables. proplene (polyproplene) or nylon (polyamide)

Answer 7

nylon (polyamide). has irritating ends so leave them longer.

Question 8

when do you choose taper point vs reverse cutting point of a needle.

Answer 8

taper point isn’t as sharp so it is for soft tissues where we dont want to make a larger hole. think bladder.
reverse cutting is for tough things. fibrous. stays sharper because there are blades.

Question 9

type of suture best around an eyelid of a spicy animal.

Answer 9

absorbable. soft. doesnt need long tensile strength. vicryl

Question 10

skin infection in dog bites

Answer 10

nonabsorbable. Nylon (polyamide). better handling than prolene and has antibacterial properties.

Question 11

wound around anus. ulcerated. sensitive area

Answer 11

absorbable (vicryl, monocryl (poligecaprone), and PDS (polydioxanone)). nonbraided and can be used in contaminated site. monocril or PDS.

Question 12

pyometra body wall closure

Answer 12

absorbable. contaminated. long tensile strength. PDS (polydiozanone)
