2. DENT 1260 IC Unit 5 Unit 5 Sterilization

3. 1. 3 methods of HEAT Sterilization Autoclave- steam under pressure Chemclave- chemical heated under pressure Dry heat- heated air

4. Autoclave

5. 1&2 time, temp pressure + - Autoclave 250F 20-30 min 15psi + liquids, time - corrosive, no closed container, wet (wick)

6. Flash cycle- Statim 273F 3-10 minutes

7. Chemclave- unsaturated chemical vapor

8. Chemclave 270F 20 min 25psi Formaldehyde and alcohols + time, dry - need ventilation, no liq, no cloth or cotton

9. Dry Heat

10. Dry heat 320F 60-120 min Static air Forced Air (rapid heat transfer) + no corrosion (dry), great for sharps - time, no liq, burn some cottons

11. 3. Load and operate Keep packs, pouches and cassettes separate Place items on edge, not stacked on top of each other Keep packages facing the same direction

12. 4. How does Saturated Stem under pressure kill microbes The heat, not the pressure kills the microbes Steam sterilizers heat water to generate steam in a closed chamber, producing a moist heat that rapidly kills microbes The pressure prevents air pockets that are not the correct temp from forming

13. 5. General maintenance and cleaning Follow Manufacturer instructions Drain fluids and run cleaning solution through.

14. 7. Reasons for sterilizer failure dirty instruments packaging Loading Timing Temperature Wrong method for material

15. 8. Handle and store Do not handle unless pack is DRY and with clean hands only Dry slowly- do not use fan or blower Handle as little as possible Store in clean, dry closed area

16. 9. Liquid sterilant Glutaraldehyde, 3-12 hrs, heat liable only and disposable is better Once removed- must rinse ( no longer sterile), dry and package. No monitoring Use life of glut??????????????

17. 10. Ethylene oxide, bead and oil Ethylene oxide- gas, no heat, 4-10 hrs, 16 hr post sterilization aeration Glass bead- no monitor, not true sterilization, use on endo files for same patient but not between patients Hot oil- not sterilize, handpiece lube

18. 11. Vocab Flash cycle- shorter, smaller Unsaturated chem vapor- chemclave Static air- not moving Forced air- fan, moving Sterilization failure- not sterile
