- Some ways to protect the patient during laser surgery:
- 1. Eyeshield
2. Nonflammable antiseptics
3. Flame resistant drapes
4. 4 moistened towels over drapes

- True or False:
Foot pedal for laser surgery should never be placed close to the surgeon.
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.
- Two hazards of using the endoscope on patients.
- 1. Perforations
- A hot wire use on tissue to burn it.
- High frequency electrical currents that go to the tissue between two electrodes.
- 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.
- An ESU (Bovie) mode that stops bleeding.
- Length of cycle for an ESU (Bovie).
