1. Manage infectious conditions.

2.  Write down as many infection control and cross infection issues as possible  https://www.youtube.com/watch?v=Csr8ATe pxDM https://www.youtube.com/watch?v=Csr8ATe pxDM

3.  Hep B- 1 in 3 contraction rate and can live up to 4 days in a blood spillage.  HIV- 1 in 80  Hep C- 1 in 30

4.  Meets “essential requirements”  Two sinks – scrubbing – rinsing  Water mixed with detergent or enzyme solution  Heavy duty gloves must be worn  Water temperature <45 °C  Nylon long handled brush  Below the level of the water

5.  Uses ultra sonic frequency to remove debris from instruments immersed into the bath.  This can replace manual scrubbing methods  Uses detergents and enzyme solution  Not suitable for hand-pieces Ultra Sonic Bath

8.  5 cycle stages of cleaning and disinfection Flush Wash Drying Rinse Thermal disinfection

9. Flush Initial pressure surge to remove heavy, gross and liquid debris. Must be below 45 °C to preventing protein binding Wash Detergent and/or disinfectant with water to remove further debris. Chemical and mechanical actions remove the debris. Rinse Using mains water or reverse osmosis water to remove chemical wash solutions Thermal Disinfection Pre-set temperature used to disinfect further Drying Heated air to removal residual moisture to prevent recolonisation

10. test6 monthly Automatic control test Ensure cycle parameters are achieved Chemical dosingEnsure chemicals are released into the chamber Thermometric Disinfection test Heavily soiled load, ensure optimal temperatures are achieved

11. Definition: To kill micro-organisms: bacteria, fungi, spores and viruses sterilisation cold wet dry disinfectants industrial Hot moist Steam Vacuum Chlorhexidine, sodium hypochlorite, mikrozid, gigasept gamma

12. “N” type Steam

13. “B” type Vacuum

14.  Identify the process of an autoclave and how it completes a successful sterilisation process.  Once you have completed this then identify the methods used to maintain and test the autoclave Your group will be given a type of autoclave to research

15. HTM 01-05 Section 4.2: "Saturated steam under pressure delivered at the highest temperature compatible with the product is the preferred method for the sterilisation of most instruments used in the clinical setting."

16.  Kills all bacteria, spores, fungi and viruses.  Steam is produced in an autoclave  Temperature of 134oC for at least 3 mins.  2.2 bar pressure  Autoclave performance can be checked by indicator strips.  Suitable for all metal instruments, burs, rubber and most plastics, NOT swabs, cotton wool and paper points.

17.  Kills all known micro organisms, spores and viruses.  Suitable for most dental instruments.  Sterilising time 3 minutes at 134 0 c.  Complete cycle last 15 minutes.  Cannot open the door during the cycle.

18.  Earliest models of autoclaves were unsuitable for wrapped or pouched articles and instruments were not dry at the end of the cycle.  Vacuum autoclaves allow packaged contents to be transferred dry for the autoclave.  Uses 134°C for 3 min at 2.25 bar pressure  Suitable for hollow lumens, eg handpiece  Air is removed from the chamber

19. Disadvantages in general  Can cause rust.  Not suitable for plastic instruments.  Not suitable for instrument with narrow lumen

20. Maintenance  Water should be drained from reservoir daily  Daily test to be carried out on visually the first cycle  Weekly inspection of the door seal and safety device.  Annual test of operation by authorised person.  Periodic examination by authorised organisation to ensure that it conforms to PSSR  Surgery insurance policy.

21. Gamma radiation  Suitable for sterilising pre-packed goods for medical use i.e. dental needles, swabs, cotton wool rolls  Kills all bacteria, fungi, spores and viruses.  KILLS ALL LIVING MICRO-ORGANISMS

22. In your groups research the types of disinfectants. The advantages and disadvantages, and when you would use these disinfectants Blue group – bleach based cleaners Yellow- aldehyde based cleaners Red- Chlorhexidine glucanate Green- Isoprophyl alcohol wipe

23.  Chemicals called disinfectants which kill or prevent the growth of a variety of microbes.  Chlorhexidine (Hibitane)  Sodium hypochlorite (Milton, domestic bleaches) Most disinfectants do not kill spores and some are unreliable against viruses

24.  Used in strict accordance with the manufacturers instructions, prepared to the correct strength, used for the correct period of time and not kept beyond their active or expiry date.  Hypochlorite is effective against spores, hepatitis B and AIDS virus.  https://www.youtube.com/watch?v=ePd414 wYkew https://www.youtube.com/watch?v=ePd414 wYkew

25. What is your Practice Policy regarding storage of sterilised instruments?

26. ConditionDuration Wrapped Bagged Sealed 1 year from expiry date Initialled, date of autoclave, date of expiry Unwrapped In clinical area 1 day Unwrapped in clean area 1 week

27. You have been given the job role of “Infection Control Supervisor” For a new purpose built dental practice. Your task is to create a floor plan for a decontamination area. You will be given either “essential requirement” “best practice” Utilise the HTM01-05 to assist with this task

28. HTM 01-05 requests that transport boxes are used, the attributes of which need to be: Rigid Lidded Leak proof Easily cleanable Capable of being closed securely
