Amplification
Simulated
Emmisions by
Radiation - Laser mediums include:
- Gas, dyes, crystals, and solid rods
- Laser amplification means:
- the power and density of the laser.
- LSO =
- Laser safety officer
- Some ways to protect the patient during laser surgery:
-
1. Eyeshield
2. Nonflammable antiseptics
3. Flame resistant drapes
4. 4 moistened towels over drapes
5. Leave laser to rest on a moistened towel - Some ways to protect OR personnel during laser surgery:
-
1. Protective eyewear
2. Fire resistant gowns
3. Hepa-mask
4. Plume evacuators -
True or False:
Foot pedal for laser surgery should never be placed close to the surgeon. -
False.
Foot pedals during laser surgeries should only be placed near the surgeon. - Some advantages of Lasers:
-
1. Relatively bloodless/dry field
2. Decreased postOP pain
3. Precise view of targeted area
4. Reduction in operating time - Instrument used for visual examination of an interior cavity or hollow organ.
- Endoscope
- Two hazards of using the endoscope on patients.
-
1. Perforations
2. Bleeding - A hot wire use on tissue to burn it.
- electrocautery
- High frequency electrical currents that go to the tissue between two electrodes.
- Electrosurgery
- Passes into the patients body by an active electrode and exits through a dispersing electrode.
- Monopolar unit
- Tissue forceps where electricity goes from one tine to the other. No ground plate is needed.
- Bipolar unit
- An insulating pad with conductive gel opened at time of use.
- Dispersive pad
- Highest peak voltage available for a ESU (Bovie). Used for fulgaration; large areas that need to be coagulated.
- Spray or arc
- An ESU (Bovie) mode that vaporizes cell without charing.
- Cutting
- An ESU (Bovie) mode that stops bleeding.
- Coagulation
- Length of cycle for an ESU (Bovie).
- Blend
