Laser tattoo removal consultation - ANSWER-Q-switched
laser are the ideal tools for effectively removing complex
and multi-colored tattoos. Multi-wavelingth, Q-switched
laser systems with frequency-doubled KTP are uniquely
able to produce very short pulses of intense light that pass
harmlessly through the top layers of skin to be selectively
absorbed by treatment-specific pigments.
Define laser - ANSWER-light amplification by the
stimulated emission of radiation
What are the most common uses of lasers? - ANSWER-
dentistry
,LASIK eye surgery
hair removal
photodynamic therapy (destroys cancer cells)
What are some ignition sources in surgery? - ANSWER-
electrosurgical cautery
laser
A desiccated CO2 absorber can ignite in the face of a
reaction with _________ - ANSWER-sevoflurane
What are the safest anesthesia gases to use during laser
surgery? - ANSWER-30% oxygen in nitrogen or helium
, helium can be used as a diluent (more resistant to ignition
d/t it has a high thermal conductivity)
How should anesthesia gases be managed to prevent
airway fires? - ANSWER-keep O2 less than 30%
permissive low O2 saturation is ok (want it above 90%)
d/c O2 per nasal cannula one minute before and during
laser use
scavenge the operative site with suction to prevent O2
build up
