18 Questions
What is recommended regarding the surface of surgical instruments to minimize laser beam reflection?
Non-reflective (matt) surfaces
What is a key safety measure when handling the active tip of a laser?
Deactivated after removal from the surgical site
Why should nitrous oxide be avoided in medical settings?
It supports combustion as readily as oxygen
When using electrocautery or a laser, what is the ideal timing for discontinuing supplemental oxygen?
At least one minute before using electrocautery or a laser
What is the purpose of using helium in place of nitrogen in gas mixtures?
Reduce the risk of ignition
How can the time to ignition of surgical drapes be increased according to the text?
Lowering oxygen concentrations
What feature of the Mallinckrodt LaserFlex™ endotracheal tube helps alert the surgeon of a rupture?
Tinted with methylene blue
What is the purpose of the second cuff in the Mallinckrodt LaserFlex™ endotracheal tube?
To maintain a secure airway
What is an alternative, less expensive method to the specially designed laser-resistant tubes for airway laser surgery?
Endotracheal tubes wrapped in metallic foil
Which material is NOT recommended for wrapping endotracheal tubes due to its vulnerability during airway laser surgery?

What is a measure to minimize the risk of ignition during airway laser surgery?
Soaking up flammable agents
What is the recommended ventilation strategy for patients undergoing procedures involving electrocautery or laser to the airway?
Ensure the cuff pressure is sufficient to eliminate oxygen leakage into the surgical field
What action should theatre team members take to effectively manage airway fires?
Immediately adopt previously assigned and rehearsed roles
Why are cuffed endotracheal tubes preferred over uncuffed tubes in procedures involving electrocautery?
To reduce the risk of electrocautery-induced fires
What technique is recommended to avoid inadvertent cuff puncture during tracheostomy formation?
Filling cuffs with saline
Why should supplemental oxygen be provided via a closed circuit or secure airway instead of an open circuit?
To minimize the risk of electrocautery-induced fires
What should be ensured when placing endotracheal tubes for high-risk procedures involving laser?
Maintaining safe distance from vocal cords and carina
How can leakage from uncuffed endotracheal tubes contribute towards electrocautery-induced fires?
By allowing gases to escape into the oropharynx
Learn about different types of endotracheal tubes specially designed for airway laser surgery, including the Mallinckrodt LaserFlex™ and the Bivona Fome-Cuff®. Explore a less expensive alternative involving metallic foil, compared to these specialized options.
