If you can find the cricothyroid membrane by palpation, why would you waste steps to use a needle and a wire? You have to know where the correct position is before inserting the needle, so why not just go ahead and make the incision with the scalpel?
You can't be sure that you don't back-wall, but as long as you can aspirate air you are most likely in the trachea, and should be able to pass a guide wire. But at least in our hospital this method is no longer used, we ONLY teach the scalpel-bougie technique. It is faster and has higher success rate.

Higher risk of bleeding into the trachea, not safe to do on ward level by unspecialised staff
Ikr why?
What needle is used initially?
How long we can ventilate with cricothyroidotomy tube maximum
24-48hrs
But how come the posterior wall of the trachea is not pierced?
