Flashcards in Surgical infections Deck (20):
1

What does the development of an infection depend on?

Number/Virulence of bacteria
Competency of host defense
Amount of tissue damage
Dead space resulting from surgery

2

What are the ages that are most at risk for surgical infection?

> 10 years old

3

Why are dogs over 10 more at risk than others

Concurrent disease likely possible
Immune response is dulled

4

Why are dogs under 1 year more at risk than other dogs?

Under-developed immune system

5

What are some other risk factors that can occur at any age?

Protein-calorie malnutrition
Immunosuppressive drugs
Extended hospital stay
Drains/catheters present

6

What factors in a wound allow for the increase of bacterial growth?

Hematoma + Seroma
Foreign bodies
Excessive dead space
Large amounts of necrotic tissue

7

How long can cephalic catheters remain in?

48 to 72 hours

8

How long can jugular catheters remain in?

7 to 10 days

9

What is the longest you should keep a urinary catheter in?

2 to 3 day s

10

What aspects are necessary if you want to reduce the risk of infection with urinary catheters?

Closed collection system
Dont leave them in, do intermittent catherterization

11

What four aspects can be carried out to reduce infection risk?

Meticulous surgical technique
Copious wound lavage
Closure of dead space
Appropriate antibiotic resistance

12

Why can hypothermia increase infection risk?

Innate cells do not work as well in the cold

13

What happens to the tissues with rough handling that can increase the risk on infection?

Reduced oxygen tension
-- and --
Phagocytes + Humoral immunity are diminished

14

What should be done before you start treating a superficial infection?

Culture - you can start treatment right after

15

What happens if implant is involved in the infection?

Must be removed

16

Why should topical antibiotics be used with caution?

Can lead to damage of the skin and therefor reduce healing

17

Why doesn't antibiotics work on implants?

AB won't penetrate, bioflim prevents AB from getting to bacteria

18

What is the most common implant inflection?

Dental prophylaxis

19

What are the three goals of antibiotic infection?

Low toxicity
Kills bacteria at site of infection
Does not negatively influence the host immune system

20

When does inflammation become an infection?

Purulent discharge
