(May-2008 Q9) A 25 yo man is to have laser surgery for a vocal cord papilloma. What are the hazards associated with the use of laser in this situation and how can they be minimsed?
Laser defined as: Light Amplification by Stimulated Emission of Radiation
Hazards of use are mainly related to airway fire due to ignition by heat generated from the laser beam.
It can be minimized by surgical preparation and anaesthesia factors
Surgical preparation: use laser in short bursts
Sterile water for irrigation should always be available.
OT preparation
In the event of an airway fire, irrigation with saline or sterile water
Anaesthesia factors: use as low an FiO2 as possible (as low an oxygen concentration to maintain adequate oxygenation)
Vigilance
Use of ETT with ? wire/armoured tube
Laser may cause airway papillomas?
LASER officers, fire drill
types of laser: CO2, Yag, ?
