Hi Ross, Nils here ;) love your videos - just a comment: could/ should you not also apply your protip nr 2 (video: endoscopic intubation through SGA), where you attach your bronchoscopic airway adapter (onto SGA instead of ETT) for this Aintree technique?
Hi Nils! Thanks for the kind comments, and good question/suggestion. The answer is going to be a little less satisfying: "It depends." The Aintree is designed with an internal diameter to fit the majority of paediatric flexible bronchoscopes, and so the outer diameter is just narrow enough to fit comfortably into a 6.0 mm ID ETT. This means that it is already fairly thick, but below the diameter of an "adult" (5 mm ED or greater) bronchoscope. Hence, it depends on the model and design of the bronchoscopic adaptor/catheter mount. If it is designed for adult bronchoscopes, it will fit fine while introducing the Aintree, but you'll have to remove it before railroading the ETT (a 6.0 mm ID ETT has an external diameter of around 8.5-9.0 mm depending on brand). You'll buy some time, especially during the tricky scoping period, but you won't be able to ventilate throughout. Hope that helps!
