SPOT THE PROBLEM….. Write down as many infection control
and cross infection issues as possible

DID YOU KNOW……
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
MANUAL SCRUB
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
DISINFECTION
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
WASHER DISINFECTOR
5 cycle stages of cleaning and disinfection
Flush
Wash
Drying Rinse
Thermal disinfection
Flush Initial pressure surge to remove heavy, gross and
liquid debris. Must be below 45 °C to preventing protein binding
WashDetergent and/or disinfectant with water to remove
further debris. Chemical and mechanical actions remove the debris.
RinseUsing mains water or reverse osmosis water to remove
chemical wash solutions
Thermal DisinfectionPre-set temperature used to disinfect further
DryingHeated air to removal residual moisture to prevent
recolonisation

IN YOUR GROUPS……
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
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."
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."
STEAM STERALISATION
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.
AUTOCLAVE
Kills all known micro organisms, spores and viruses.
Suitable for most dental instruments. Sterilising time 3 minutes at 1340c. Complete cycle last 15 minutes. Cannot open the door during the cycle.
VACUUM AUTOCLAVE 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
AUTOCLAVE Disadvantages in general Can cause rust. Not suitable for plastic instruments. Not suitable for instrument with narrow
lumen
AUTOCLAVE 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.
INDUSTRIAL STERILISATION 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
DISINFECTANTS
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
DISINFECTANT
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
RULES! 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.

YOUR OWN DECON ROOMYou 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
