Flashcards in T3: Setting Up the Theatre and Anaesthetic Machine Deck (24):
1

What is the aim when setting up the theatre?

  •  For the theatre to be prepared in such a way that it is fully functional when the patient is brought in.
  • It is therefore unnecessary for staff to undertake last- minute fetching and carrying once the procedure is underway.

2

When setting up the theatre in the morning, what is the first thing that should be done?

Theatre should be damp-dusted w/ clinics preffered disinfectant at correct dilution.

Start at top (lights) and work to bottom

3

Describe how you would check/set up the anaesthetic machine?

  • check the isoflurane level and refill if necessary
  • check that the oxygen supply is connected and functional
  • check the soda lime and change if necessary
  • perform leak test on the anaesthetic machine
  • connect the appropriate circuit for the first patient of the day

4

What things other than damp-dusting and checking anaesthetic machine should you do when setting up the theatre?

  • check monitoring equipment (leads, calibrated, power supply, pressure cuffs)
  • turn on heat pad
  • check lights
  • clean bin liner
  • any positioning aids ready
  • fluid pump is working
  • PREPARE SCRUB AREA

5

How should you clean the theatre between patients?

  • switch off equipment (unless N/A some machines left on to hear up)
  • all instruments and equipment used in previous procedure removed
  • detach light handle
  • wipe surfaces w/ lint free cloth
  • clean bed on surgery table
  • remove rubbish and replace liner
  • clean oesophageal stethoscope etc
  • check iso/soda lime
  • sweep/mop/tidy

6

What is antisepsis?

refers to the killing of micro-organisms within living tissue, for example treating a contaminated wound.

7

What does aseptic technique mean?

establishing conditions that prevent the contamination of surgical wounds.

8

What are the three main sources of infection?

  1. Environment
  2. Theatre personnel
  3. The animal

9

What are the 3 stages of cleaning?

  1. Removing gross contamination
  2. Disinfecting
  3. Sterilising

10

3 stages of cleaning:

how do we remove gross contamination?

  • using detergents (de-fatting agents) which remove grease and oils
  • using mechanical aids such as mops
  • pest control (e.g. mouse traps and cockroach baits)
  • regular removal of rubbish from the site (e.g. emptying bins)
  • This discourages the growth and multiplication of disease-carrying vermin and micro-organisms.
  • Removal of obvious dirt and organic materials is essential prior to treatment with many antiseptics and detergents, in order to increase their effectiveness.

11

3 stages of cleaning:

What does disinfection involve?

  •  removes and destroys most micro-organisms, except some viruses and heat resistant bacteria and bacterial spores
  • eg chlorhex, iodine, alcohol, chlorine
  • [ ]  and time of contact essential to effectiveness
  •  

12

What is an antiseptic and give some examples

  • mild disinfectants for use on live tissue
  • chlorhex, povidone-iodine, cetrimide

13

What equipment and requirements should a prep or induction area have?

  • seperate from but in close proximity to theatre
  • own anaesthetic machine, IV pump
  • other equip needed:
    -heat nat
    -ET tubes/ties
    -IV catheter
    -antiseptic skin prep and swabs
    -needles/syringes
    -anaesthetic spray (cats)
    -adhesive tape
    -monitoring equip
    -pump/fluids
    -vaccuum cleaner
    -rubbish bin
     

14

How long after being autoclaved is a surgery pack still sterilised?

up until 3 months past autoclave date

15

What are the functions of anaesthetic machines?

  • Supply oxygen
  • supply anaesthetic gases and vapours
  • remove carbon dioxide
  • inflate animals lungs

16

What is soda lime used for?

  • absorb CO2 breathed out
  • colour change occurs as it becomes exhausted, though this should not be relied upon to indicate freshness
  • should be changed when 50% becomes coloured

17

Describe a circle breathing system

 

Q image thumb

 components of a circle system include:

  • a fresh gas inlet
  • an inspiratory one-way valve
  • an expiratory one-way valve
  • a reservoir bag
  • corrugated tubing (both inspiratory and expiratory)
  • a Y-piece where the endotracheal tube is attached
  • escape valve where scavenger is attached
  • soda lime canister
  • vaporiser (VIC systems only)

18

Describe a T-piece breathing system

Q image thumb

  • used for animals that weigh less than 10kg
  • To check for leaks:

    close the hole in the end of the bag and the patient connection

    allow some gas into the system, and then squeeze the bag to locate any leaks

19

A bit about flow meters?

  • controls flow of gas to patient
  • small cyndrical bobbin is displaced upwards when gas is flowing
  • flow rate indicated from top of bobbin
  • rotation of bobbin indicates gas flow

20

Descrive a passive scavenger system

  •  rely on gas moving into a cylinder containing charcoal such as a scavcan that filters the gases, or by a tube going out of the room outside

21

Describe an active scavenger system?

  • connected to a suction pump that then filter out the gases.

22

Why do we intubate patients?

  • to protect and support the patients airway because anaesthesia removes the muscular supports.
  • minimise the gas pollution and provide safer anaesthesia by removing anatomical dead space.

23

Describe how to select the correct ET tube?

  • can check distance between nares
  • measure from nose to point of shoulder
  • make sure not too much over hang from mouth
  •  

24

How do you clean an ET tube?

washed in disinfectant/detergent, may use pipe cleaner and hang to dry

once dry, wipe over with alcohol
