The surgeon prefers a small diameter ETT to facilitate the view of the airway. The nickname for MLT is "mighty long tube"! List two differences between the ETTs illustrated in the picture above that make the MLT more advantageous for ENT procedures in adults that necessitate a small diameter tube. Both characteristics are a better match for the adult airway; pediatric tubes may be too short to properly position below the vocal cords and the cuff is too small to prevent leaks in the adult airway without overdistending and creating high cuff pressures that could injure tracheal mucosa. The most frequent laser related complication is airway fire. Laser Resistant ETTs are used to prevent airway fires during laser surgery of the airway. Initially, fires are located on surface of ETT and cause thermal injury to tissues. If the fire burns through to interior of ETT, O2 and positive pressure ventilation create a blow torch effect, blowing heat and toxic products down into lung.

With the same preformed curve that helps remove the circuit from the surgical field, these tubes are ideal for surgical procedures where aspiration is a concern.

Anand H Kulkarni, Sumesh T. Generally the use of a nasal Ring-Adair-Elwin RAE endotracheal tubeis not encouraged during fibreoptic intubation, because its preformed curvature and longer length interfere with fibrescopy and also there may be difficulty advancing the tube over the fibreoptic bronchoscope into thetrachea1. Another major disadvantage of using the nasal RAE tube includes difficulty in passing a suction catheter through the preformed curvature2. This factor assumes heightened importance due to the fact that these tubesare commonly used in major oral and neck surgeries where retaining the tube post-operatively is common and a blocked tube can be disastrous.
