wound section 6

Question 1

most predictive factors for infection

Answer 1

wound characteristics of location, age, depth, configuration, and contamination

Question 2

hypertropic scars

Answer 2

due to tissue tension during wound healing, and the scars stay within the original wound boundaries and tend to undergo partial spontaneous regression within 1 to 2 years

Question 3

Keloids

Answer 3

genetically linked variations in wound healing, resulting in the production of excess collagen beyond the original wound boundaries. Keloids rarely decrease in size.

Question 4

major inorganic soil component responsible for infection

Answer 4

Clay

Question 5

Finger tourniquets time

Answer 5

not more than 30 minute

Question 6

*history of fight + lacerations in these areas are considered as human bites

Answer 6

Lacerations over the metacarpophalangeal joints

Question 7

Sonography usefulness in Foreign body detection

Answer 7

good for detecting wood >2.5mm size

Question 8

visible on plain radiographs

Answer 8

Metal, bone, teeth, pencil graphite, certain plastics, glass>2mm, gravel, sand, some fish bones, some painted wood, and most aluminum

Question 9

Full sterile technique and infection

Answer 9

(cap mask gloves) does not reduce the incidence of postrepair infections

Question 10

hand antisepsis

Answer 10

hand antisepsis prior to wound repair in the ED is unproven

Question 11

gloves and infection

Answer 11

Clean, nonsterile gloves have similar postrepair infection rates when compared to sterile gloves

Question 12

on infection and ED

Answer 12

time and cost savings per laceration by using common-sense cleanliness.

Question 13

Prior to local anesthesia, one must?

Answer 13

sensory, motor, and vascular examination should be performed at, and distal to, the wound site.

Question 14

Low pressure irrigation

Answer 14

0.5psi, uncontaminated wounds and for loose tissues around the scrotum or eyelids

Question 15

high pressure irrigation

Answer 15

7psi or higher, high levels of contamination, especially in areas of the body that are at higher risk of infection such as the extremities, 18 gauge intravenous catheters
50-mL syringe with a splash guard

Question 16

Outdated methods to clean wounds

Answer 16

Wound soaking, Routine scrubbing

Question 17

recommended irrigation amount

Answer 17

60ml per cm of wound length, at least 200ml

Question 18

most commonly used irrigant

Answer 18

PNSS- lowest toxicity, comparable to tap water.

Question 19

antiseptic and irrigants (benefit)

Answer 19

no benefit

Question 20

most effective type of debridement

Answer 20

excision

Question 21

what to excise

Answer 21

tissue with poor capillary refill, jagged edges, contused tissues

Question 22

antibiotic prophylaxis for traumatic wound

Answer 22

initiated before significant tissue manipulation is done, administered in routes that achieve desired blood levels, agents that are effective against predicted pathogens

Question 23

PO or IV antibiotics for prophylaxis?

Answer 23

same. just use PO with rapid absorption

Question 24

most nonbite wound infections

Answer 24

staphylococcus, streptococci tx with beta-lactam despite mrsa (3-5days non bite wounds)

Question 25

human bites prophylaxis

Answer 25

amoxicillin-clavulanate 5-7days (bite wounds)

Question 26

treatment for laceration <2cm

Answer 26

clean wound, secondary closure

Question 27

head laceration golden period

Answer 27

100 hours

Question 28

trunk or extremities had lower rates of healing if closed morethan x hours

Answer 28

closed more than 19 hours

Question 29

wounds with high risk of infection should be closed after x days

Answer 29

4 days

Question 30

sutures advantage

Answer 30

strongest of all the closure devices and allow the most accurate approximation of the wound edges

Question 31

Nonabsorbable sutures retain their tensile strength upto X days

Answer 31

60 days
