Flashcards in Wound management Deck (14)
1

How might closed (non-penetrating) wounds become surgical wounds?

If become problematic--> open up surgically to explore/remove damaged tissues

(Abscesses, bruising, hematomas, etc.)

2

Why are traumatic wounds initially classified as contaminated at best?

Wound is open--no way to know what could've gotten into it or what the risk of infection is

Must consider 'contaminated' until proven otherwise

3

What does the term "iceberg" lesion mean with regard to dog bite wounds?

Superficial lesions usually look less severe than they actually are--do not reflect the degree of internal trauma that is usually present

4

What criteria are used to decide whether to treat a bite wound conservatively or surgically?

  • Sizes/#'s of animals involved
  • Locations of the wounds
    • Extremities more likely to be puncture wounds
    • Bites on the neck tend to slide and cause more trauma/are more severe
  • Clinical assessment of severity of trauma

5

What is a degloving injury?

  • Result of shearing forces which sever cutaneous vessels supplying skin
  • Often distal injuries

6

What is the difference between physiologic and anatomic degloving injuries?

  • Physiologic--skin devitalized but still in place
    • Remove skin as early as possible and close wounds
    • If multiple wounds that can't all be done at once: leave skin on and allow it to function as a biological bandage (remove as soon as infection occurs)
  • Anatomic--skin avulsed from underlying tissue
    • If skin is shiny and pale or dark black-->dead and needs to come off
      • Any color in between should be monitored
    • Managed as open wound

7

What is a fistula?

Communication between two epithelial surfaces

Lined by epithelium

Ex: tracheoesophageal fistula

8

What is a sinus tract?

  • Communication between mesothelial surface and skin
  • Often associated w/ FB migration
  • Can be lined with granulation tissue
  • Will "pseudo" heal with antibiotic administration but will reappear when discontinued 

9

T/F: Combined degloving and crush injuries are rare in small animals

FALSE

Common

 

10

What diagnostic tests can be used to diagnose foreign bodies?

  • Ultrasound
    • ​Most cost-effective
    • Non-radiopaque FBs (esp. plant-based)
  • Radiographs--often won't show up
  • Contrast studies--ok, but still hard to interpret
  • CT, MRI (CT if not seen on u/s)

11

Which diagnostic test is most reliable for plant type FBs and could be used intraoperatively?

Ultrasound

(intraoperative u/s)

12

What are the common etiologies of burn wounds?

  • Thermal 
    • House fires
    • Hot liquids (water/steam, grease, wax)
    • Direct contact (heating pads, heat lamps, exhaust pipes)
  • Chemical 
  • Electrical

13

What are the pathophysiologies of burn wounds?

  • Burn wound
    • Injury progression (several zones)
    • Infection
  • Smoke inhalation
    • Direct heat injury
    • Carbon monoxide
    • Inhaled toxins
  • Systemic effects
    • Cardiovascular 
    • Metabolic
