fiberoptic intubation after LMA rescue.

what is the aintree catheter?

  • Its a flexible catheter used for fiberoptically converting an LMA to an oral ETT.

  • Following intratracheal placement, a 7-0 ETT can be railroaded over Aintree and into the trachea.

  • It is shorter than an airway exchange catheter so that it can be preloaded onto a bronchoscope.

  • The aintree is compatible with any "intermediate" sized bronchoscope (i.e. the Olympus 4-0 or the Verathon Slim 3.8mm).

  • The smallest ETT compatible with an aintree is the 7-0 ETT (a smaller ETT cannot be railroaded over the Aintree)

  • ​It's also known as an Airway Intubation Catheter (AIC)

  • Comes with 2 "rapifit" adaptors (please refer to manufacturer’s guidelines for use)

additional considerations.

This should be performed in a controlled stepwise process

 

​​The process is designed to provide continuous ventilation/oxygenation via the LMA and bronch adaptor until the LMA is removed and ETT is railroaded in place

  • ​

Oxygen CAN be delivered via the Aintree in situations where railroading of ETT is prolonged; assisting ventilation via this route is often suboptimal and carries significant risk (lack of egress path for exhaled gas/lack of cuff/elevated barotrauma risk)

  •  

Refer to manufacturer’s guidelines for methods of oxygen delivery

​

Additional Recommendations:

​

Consider a second anesthesia provider in addition to a trained assistant

​

The Aintree catheter is not recommended with the LMA Supreme
