infection, prevention and decontamination sciences intro Flashcards
1
Q
what is an operator
A
- any person with the authority to operate a steriliser/washer disinfection including the noting of device readings and simple housekeeping duties
2
Q
why do you need to keep a record of sterilising
A
- must be able to prove instruments have been sterilised and tested
- need paperwork to prove everything
- if it is not document, it did not happen
3
Q
where is equipment sterilised
A
- transferred to a local sterilisation department
- central decontamination unit (CDU)
4
Q
why is equipment taken to CDU
A
- easier than making dental practices do it themselves
- makes sure everything is cleaned the same
5
Q
what is the Spaulding classification
A
- critical
- semi-critical
- non-critical
6
Q
what does critical mean in Spaulding classification
A
- devices that enter tissue that is usually sterile or enters the vascular system
- needs to be STERILE
7
Q
what does semi-critical mean in Spaulding classification
A
- instruments have contact with intact mucous membranes but do not penetrate sterile tissue
- sterile preferably or high level disinfectant
- dental mirror
8
Q
what does non-critical mean in Spaulding classification
A
- instruments have contact with intact skin only
- disinfect/clean
9
Q
what Spaulding classification are handpieces
A
- unsure
- critical or semi-critical
- debated
10
Q
why do we need sterile instruments
A
- reduces probability of infection transmission
- international standards for surgical instruments
- legislative and professional standards
- maintaining high quality of care for patients
11
Q
what is the definition of sterile
A
- probability of micro-organism being on instrument is less than or equal to 1x10(-6)
12
Q
what is the life cycle of re-usable surgical instruments
A
- cleaning, disinfection, inspection, packaging, sterilisation, transport, storage, use, transport
13
Q
what does operator need to do
A
- single use devices where practicable
- automated washer-disinfectors
- inspection
- pock it
- sterilise it
- record keeping
14
Q
why do we need to worry about CJD
A
- prions are more difficult to inactivate on surgical devices
- infectivity can survive steam sterilisation at 134 degrees for 18 minutes
- has potential to leave some residual material
15
Q
what is the suspected asymptomatic carriage of CJD in UK
A
- 1 in 2,000
