1. A tray of cystoscopy instruments was displayed.
Q: How long should this tray of instruments be sterilized?
|
A. 3 minutes
B. 10 minutes
C. 15 minutes
D. Should not be Flashed
|
Porous items and lumened instruments must be flashed for
10 minutes in a gravity sterilizer
|

2. The same tray of instruments as in question #1 was
again displayed. The chemical integrator and autoclave printout supported
a ten minute autoclave run.
Q: This tray was sterilized for 10 minutes. Is it sterile?
|
A. Yes
B. No
|
All valves in the tray were closed. Steam cannot
penetrate through closed valves. This tray should be considered unsterile
secondary to improper instrument preparation.

3. A tray of minor non-porous and non-lumened
instruments was placed in an autoclave. A previously used chemical
integrator was left in the tray. The autoclave jacket pressure was set at
20 lbs of pressure. The printout indicated a flash cycle of 3 minutes.
Q. Is this tray sterile?
|
A. Yes
B. No
|
Although the integrator indicated that the parameters of
sterilization had been met, the autoclave jacket pressure of 20 lbs would
not have allowed the autoclave to sterilize the instruments in three
minutes. Closer review of the printout would have shown a three minutes
flash run but at a temperature of 257 degrees F. Correct temperature
setting should be 271-273 degrees F. Staff are expected to know the
correct operating parameters of the autoclaves. This tray is presumed to
be unsterile.

4. A 3-M mini driver drill assembly was displayed. A
list of the manufacturer’s recommendations is posted next to each
autoclave.
Q. How long do you flash sterilize this tray
|
A. 10 minutes
B. 15 minutes
C. 55 minutes
D. Should not be flashed
|
AORN recommends to “check with the manufacturer of the
equipment being used to determine the correct cycle for the particular
equipment.” In their haste, many staff forgot to look at the posted
recommended parameters.

5. A Dyonics arthroscopic shaver was displayed.
Q: This tray was flash sterilized for 10 minutes. Is it sterile?
|
A. Yes
B. No
|
Although 10 minutes was the appropriate time, the
suction valve for the shaver was closed. This instrument should be
considered un-sterile secondary to improper instrument preparation.
|

This outcome is the same as question #2 which tested the
same principle.
|
|
6. A typical tray of minor non-porous and non-lumened
instruments was placed in an autoclave. The chemical integrator lying in
the bottom of the autoclave indicated that the conditions of sterilization
had been achieved.
Q: is this tray sterile?
|
A. Yes
B. No
|
A three step process must occur when assessing the
success of a sterilization cycle.
1) Read the printout to see if the run was successful and what parameters
were used.
2) See if the chemical integrator or indicator responded to a
sterilization cycle.
3) Inspect the instruments to assure that they were properly prepared and
the appropriate cycle was chosen.
The printout at this station was blank indicating that
the autoclave had not recently run. The integrator was not placed in the
tray and was most likely an old integrator from a previous run.

7. The following question was posted on an autoclave.
Q: What type of Autoclave is this?
|
A. Gravity only
B. Hi Vac only
C. Gravity/Hi Vac Combined
|
Staff are expected to be familiar with the capabilities
of the equipment they are using. Fundamental to that is an understanding
with regard to the type of equipment they are using.

8. A Craniotome was on display.
Q: How long should you flash sterilize this tray?
|
A. 3 minutes
B. 10 minutes
C. 55 minutes
D. Should not be flashed
|
Specific power instrumentation is posted at each
autoclave. Manufacturer’s recommendations must be followed.
|

As in question # 4 the haste of the
moment caused the staff to forget that the proper parameters were posted
at the autoclaves.

9. A microaire 2000 was on display.
Q: How long should you flash sterilize this tray?
|
A. 3 minutes
B. 10 minutes
C. 30 minutes
D. Should not be flashed
|

10. A Padgett dermatome was on display.
Q: How long should you flash sterilize this tray?
|
A. 3 minutes
B. 10 minutes
C. 55 minutes
D. Should not be flashed
|
This Padgett requires gas sterilization. Staff may not
only injure patients with improper practice but also can damage or shorten
the effective life of instrumentation if improper sterilization parameters
are used.

11. A tray of maxio-facial implants was on display.
Q: How long should this tray be flashed?
|
A. 3 minutes
B. 10 minutes
C. 15 minutes
D. Should not be flashed.
|
AORN, AAMI, and the CDC recommend against the flash
sterilization of implantable devices. If necessary you must use a 10
minute cycle and a biological indicator.

12. A single orthopedic screw was lying on a huck towel
in a tray.
Q: how long should this screw be sterilized?
|
A. 3 minutes
B. 10 minutes
C. 15 minutes
D. Should not be flashed
|
As above. Staff were also reminded that if the towel
they are using came from a previously sterilized tray, they need to
moisten it before placing it in the autoclave. This prevents the phenomena
of localized superheating which inhibits the sterilization process.

13. A tray with an orthopedic screw and plate lying on a
huck towel was on display.
Q: This tray was brought to you from the autoclave. Should you accept
is as sterile?
|
A. Yes
B. No
|
The tray had no integrator and biological indicator. The
current polity of the OR directed scrub staff not to accept trays without
integrators. Also, the tray contained no biological indicator and
contained implants. This is contrary to recommended standards.

14. A tray known as a “Flash Pak” was on display.
Q: What is this used for?
|
A. Transporting flashed
instruments
B. Transporting gassed instruments
C. Transporting instruments soaked in Cidex. |
The “Flash Pak” is one of several industry available
trays to assist OR's with the problem of transporting moist flash
sterilized instruments through open hallways without exposing them to
potential pathogen contamination. They also allow for more efficient use
of the flash sterilizer by allowing the operators to perform multiple room
runs and not tying up the autoclave for a particular room.

15. A tray of instruments was on display. The tray still
contained the internal wraps used to separate and organize the
instruments.
Q: The outside wrapper of this tray was torn so it was flashed for 10
minutes. Is it sterile?
|
A. Yes
B. No
|
The issue for this tray is that all internal wrappers
need to be removed. Once sterilized, these papers are so dry that they
reduce the moisture in the saturated steam creating a physical phenomenon
called superheating. Superheating inhibits the process of steam
sterilization.

16. A tray of laparoscopic endoscopes and light cords in
a Sterris container.
Q: Are these instruments sterile?
|
A. Yes
B. No
|
The chemical indicator on the Sterris container had not
changed indicating a process failure.
