20
Q

LASER safety precautions

A
  • Restrict access to area
    -Close all doors and windows
  • post warning signs
    -eye protection for pt and people
    -cover all exposed skin
  • remove bright reflective objects
    -maintain room lights as bright as possible
    =alarm to indicate use of laser
    -don’t leave laser unattended
    -keep laser beemabove/below normal line of sight
    -avoid looking into primary beam at all times
21
Q

Anesthesia gases during laser use

A

<30%O2. Avoid NO. Special ETT (laser approved). LMA sensitive to laser

22
Q

Eye trauma from lasers

A

May not be readily apparent. Color vision goes first. Depends on intensity and wavelength.

23
Q

Smoke plume

A

Pollution from cauterya nd laser six. Fine particulates in plume that may contain viruses, bacteria, tissue, fungus. Use protective masks o

24
Q

Ordinary protective mask

A

5 micrometers particulates

25
Q

High efficiency mask

A

0.1-0.3 micrometers

26
Q

Class 1 WOUND

A

Clean. No s/s infection. Risk infection <2%

27
Q

Class 2 wound

A

Clean-contaminated. No s/s infection. Repairing or removing an organ (appy) <10% risk of infection

28
Q

Class 3 wound

A

Contaminated. Open wound with blood/body fluids present. Up to 20% risk of infection

29
Q

Class 4 wound

A

Dirty. Infection already present. 40% risk of infection

30
Q

Low level disinfection

A

Kills vegetative bacteria and some fungus and virus but not TB and spores

31
Q

Intermediate level

A

Kills vegetative bacteria, fungus, virus, and TB but no spores

32
Q

High level disinfection

A

Kills all organisms and spores but not CJD

33
Q

Sterilization

A

State of being free from all organisms

34
Q

Steam sterilization

A

Time based on temp. Needs to dry at room temp, Can damage sensitive equipment

35
Q

Dry heat

A

Items that may be damaged by moisture. Time varies depending on temp

36
Q

Direct and indirect effects of radio action therapy

A

Direct- breaks down atoms of DNA and other genetic components

Indirect-impairs protein, enzyme function

37
Q

LASER stands for?

A

Light amplification by the Stimulated Emission of Radiation

38
Q

4 classes of LASERS?

A

Class 1- CD player
Class 2- Laser pointer/scanner
3- entertainment light shows
4- medical lasers (eye damage, fire hazard, airborne contamination)

39
Q

Precaution with ETT and lasers?

A

PVC easily ignites
Rubber tubes are more resistant
LASER approved tubes should be used (double cuff to prevent leaking of gas if cuff is ruptured)

40
Q

What do you do if fire in OR?

A 
Turn off o2 and ignition source
Remove ett/drapes
Extinguish fire
Ventilate with 100%
Assess for damage
Reintubatr
41
Q

Noise pollution in OR?

A

Can be as high as 125 dB with surgical saws and power tools.

42
Q

Complications of noise pollution

A 
Inability to hear alarms
Interfere with communications
Increased level of endogenous catecholamins
Irritability
Increased BP
HEARING LOSS
43
Q

Radiation Therapy

A

Harmful effect- direct breaks atoms of DNA and other genetic components

Indirect - Impairs protein, enzyme function

Exposure
ASLARP
Law of inverse squares (1/d2)

44
Q

LASER pulses can result in:

A

Tissue rupture and damage of retina
Corneal photokeratitis
Cataracts
Loss of color vision

45
Q

Talk about equipment and various levels of sterilization?

A 
Critical
-sx instruments and implanted devices
-sterilized
Semi critical
-anesthesia equipment (laryngoscopes/blades)
-high level disinfection
Non-critical
-pulse ox, BP cuff, cables
-low level
Single use
-Sterilized
-Single pt use
46
Q

Various methods of sterilization?

A

Pasteurization (30 min 700 deg C)

Steam (autoclaving)

  • time based on temp (15@120, seconds at 1500c)
  • needs to dry room temp
  • can damage sensitive equipment

Dry head

  • items damaged by moisture
  • time varies based on temp

Chemical
-high concentration of low ph can damage equipment

Gas sterilization

Radiation
