What is the tube down the throat? TEE ?? or something after surgery?
They are talking about the ventilator tube. The ventilator is the machine that breathes for you during your surgery. In most cases, when you leave the operating room, the machine is still breathing for you. The doctors and nurses watch you as your anesthesia wears off and you become able to breathe on your own. When you "wake up" in the Intensive Care area, the machine may still be helping you to breathe, so you will have a tube going down your trachea (windpipe).
A lot of people think this sounds creepy -- I know I did! But most of the people here say that they don't remember it, or they barely remember it. When you get out of surgery, you are on a LOT of drugs! I had been worried about the creepy tube, but it turned out not to be a bother at all -- all I really remember is having it removed.
About TEEs: They put a camera down your throat for the TEE. In my case, I was so sedated that I don't remember the procedure at all, from start to finish. I think that is pretty typical. Just because they say it's "sedation" rather than "anesthesia" doesn't mean that you won't totally fall asleep!
