>= 7
4.7 inner diameter
Easily preloaded over 4.2 mm diameter fibrescoped
Comes with 2 rapifit adaptors - allows oxygen administration but be
cautious of barotrauma/perforation Max. depth 26cm
Max O2 flow rate = 2L/min
(Louise airway notes)
4.Describe the process of using an Aintree to intubate through an LMA: How to use
to intubate through an LMA (EXCEPT THE SUPREME LMA)
2 person technique
prepare fibrescope and camera system
lubricate outer surfaces of both AIC and
fibrescope (FS) Preload AIC onto FS and
secure with tape
Attach a Bodie-Y connector (aka a 15mm bronchoscopic swivel connector (with
port)) to the LMA and anaesthetic circuit this enables ventilation while you are
using the FS
Confirm adequate anaesthesia, mm relaxation and assisted ventilation
Get assistant to hold LMA still
Introduce FS loaded with AIC thoguth the top port of the Bodie-Y connector
Advance until you are ~ 3cm above the carina
Note depth of AIC (MAXIMUM DEPTH 26cm)
Remove tape attaching AIC to FS
Withdraw FS while keeping AIC in situ at the same depth
Withdraw LMA while keeping AIC in situ at same depth
Railroad ETT (conventional size for F or M size 7 - 8) over AIC
Use laryngoscope to ensure position of ETT
Remove AIC and reconnect circuit -> confirm ventilation + anaesthesia
Consider FS to confirm ETT position

5. Describe the Cook Airway Exchange Catheter (AEC). Describe the process of using
the Cook AEC:
6. Compare and contrast a Cook AEC and Aintree?: Both are: long hollow tubes, able
to
ventilate, both have maximum depth of 26cm and max O2 flow rate of 2L/min,
both have risk of barotrauma and perforation.
Difference: Cook AEC - various sizes, long 100cm soft tip or shorter 83cm; Aintree
can thread a bronchoscope through and bronchoscopically guide
7. What equipment do we commonly place down an ETT?: EQUIPMENT THROUGH

8. What concurrent diseases do obese patients have that affect airway
management?: OSA:
70% of pts with BMI > 35 will have OSA or OHVS (20% of pts with OSA)
These pts are likely to require HDU
DM (gastroparesis)
GORD
HH
9. What are the classes of obesity?:
10. Why is BMV/Facemask ventilation such a problem with the morbidly obese?-
: Obesity and OSA are predictors of difficult BMV
if there is any concern about ability to BMV -> careful consideration should be
given to intubating AWAKE
11. Why is LMA insertion such a problem with the morbidly obese?: chest
compliance “
-> difficult ventilation via LMA
In pts with BMI > 35 - LMA's are unreliable as rescue devices
12. What are the concerns with intubation of morbidly obese patients?: In pts with
BMI > 35 intubation should be the default means of managing the airway
LMAs are unreliable
Use of a SGA should be restricted to extreme cases where: the pt can SV, the
procedure is short and the pt can be ramped for the entire time - to enable
quick, easy intubation Predictors of difficult laryngoscopy:
- Neck circumference
- Pre-tracheal soft tissue >2.5cm predictor of difficult airway
Morbid obesity is a weak predictor of failed intubation
Aspiration risk: obesity is a risk fx for reflux, HH, diabetes (gastroparesis), gastric
banding - these all the risk of ‘ aspiration
RSI should be performed in obese pts with risk fx for aspiration in addition to
obesity
