Right. Everybody is different, and the information you have given in your OP is not very clear, understandably.
Anatomically, everybody is different, some people are harder to intubate than others. Because of the size of the mouth opening, larinx, epiglottis, how far out or back your mandible is etc etc etc. There is an infinite variation.
Facial reconstructions/fractures/swelling/trauma etc also can make intubation hard.
So, if the anaesthetist recognised it as a difficult intubation for whatever reason, they took you to theatre because it is the best and safest place to perform the procedure.
There are a number of things you need to have in place to ensure the procedure is a success. Most and foremost, having the people and the equipment. And who would be best at it than the people who do this day in and day out?
So, they took you to theatre, and it takes time. You are attached to monitors, they ensure your IV access is ok, you are given oxygen for a bit to ensure your lungs/blood carries the best possible amount (of oxygen).
This takes a bit of time.
Then it’s the equipment. There are several types of equipment that can be used. They all have to be lined up, checked, ready to go. That takes a bit of time too. Not that you need them all. But in case you need them, you want them there, ready to just be picked up.
The procedure itself can take some time. There are moments when you try, moments when you wait to see everything’s ok. You’re being monitored for all sorts, oxygen, airway patency, blood pressure etc. This also takes a bit of time.
All in all, one hour is not abnormal at all.
Your best bet is to ask to speak to the anaesthetist. Yes, they are busy, but they are also aware people deal with what happened to them in a different way. Nobody is going to roll their eyes or dismiss you. They want to help you get better. It’s ok, go and ask, nobody will mind.
Can I just say, I’m sorry you’ve been through a rough time. Wishing you healing and peace of mind.
