1

Sterilization

The destruction of all organisms and spores on an object

2

Disinfection

The destruction of the vegetative forms of bacteria but not the spores

Organisms may still remain, but they have been altered to a state in which they are no longer harmful. With sterilization, everything is destroyed or eliminated. It is possible to sterilize instruments, but it is not possible to sterilize our patients. That is why we disinfect them

3

Disinfectant

Chemicals applied to inanimate objects to destroy the vegetative forms of bacteria, but not necessarily the spore forms

4

Antisepsis

Prevention of infection by inhibiting the growth of infectious agents

5

Disinfection time

Time required for a particular agent to produce the maximal effect

6

Autoclave standard

Autoclave tape versus indicator strip
Dry heat

15 min at 15 psi, 121 C or 250 F

Steam exposure versus right time/temp/psi

1 hr, 170 C (340 F)

7

Flash sterilization

For emergencies

131 C or 270 F, 15 psi, 3 min non porous 10 for porous

8

Ethylene oxide

Things that can't be autoclaved. Cautery pens, light source wiring for endoscopes, nitrogen drill tubing, staplers

9

Cold sterilization

Chlorhexidine, benzalkonium, glutaraldehyde

Sterility cannot be guaranteed,for minor procedures only. 3 hour soak minimum
