Steam sterilization uses what tool? What temp and time

Autoclave
121 for 15-30 minutes

12

3 requirements for autoclave to work?

Clean instruments
Correct packing, wrapping
Proper positioning in the unit

13

Gas sterilization is best used for what?

Heat or moisture sensitive equipment

14

What is the biggest drawbacks to gas sterilization (3)

Very toxic to personel if exposed
Long sterilization cycle
needs aeration before use

15

Cold chemical sterilization uses what chemical?

Glutaradehyde

16

2 caveats to cold chemical

Irritating must rinse it
Resp and dermal effects
10-12 hour duration

17

For equipment to be cold chemical sterilized it needs to be good with?

Being under water

How do we know sterilization worked?

Chemical indicators
biological indicators

20

What species do they use for biological indicators?

Non pathogenic bacillus

23

name 4 general patient factors

3 factors to patient skin preparation

Hair removal is a good thing
After anesthesia is induced or 3-10x infection rate
Avoid hair clipping the paw sif possible

25

3 goals of skin preparation

To remove dirt
reduce resident microflora
inhibit rapid rebound growth of microbes

INcrease in infection
