Aintree Intubation Catheter
Description
An adaption of the Cooks Airway Exchange Catheter, 56cm long, and with a larger
internal diameter of 4.8mm, allowing it to be pre-loaded onto a 4mm fibreoptic
intubating bronchoscope, with the directable distal tip (3cm) left exposed. The external
diameter of 6.5mm allows ET (endotracheal) tubes, with minimum internal diameter of
7mm, to be loaded onto the catheter. The Aintree system allows intubation via an
LMA (or Proseal):
Ventilation with the Aintree Intubation Catheter (AIC)...
- Insert the LMA
- Railroad the AIC over the lubricated bronchoscope
- Tape proximal end to bronchoscope
- Lubricate the AIC
- Pass the AIC/bronchocsope through the LMA, into the trachea
- Remove the bronchoscope - leaving the AIC in the trachea
- Remove the LMA - leaving the AIC in place
The Aintree system can be used to ventilate the patient, by fitting a 15 mm
Rapifit connector onto the proximal end of the catheter, to which
an Ambu bag may be attached. (The other connector is for jet ventilation)
ETT intubation through LMA...
- Railroad AIC over bronchoscope
- Tape proximal end of AIC to scope
- Lubricate AIC
- Pass AIC/scope through LMA
- Advance until carina is seen
- Remove tape from AIC/scope
- Hold AIC secure - remove scope
- Deflate LMA, hold AIC secure, remove LMA
- If ventilation required...
- Attach Rapifit connector to AIC, attach BVM to ventilate
- Remove Rapifit connector, then railroad ETT over AIC
- Railroad ETT over AIC
- Pass scope through AIC (acts as bougie)
- Hold AIC secure - advance ETT into trachea
- Inflate ETT cuff
- Confirm intubation with CO2 etc
- Remove AIC/scope
