Will be lifting you in prayer. The one of many surprises that befuddled me the most with by-pass surgery was waking up with the tube down my throat and into my lungs. I could feel it but I couldn't talk. I felt that if I panicked, they would put me back to sleep or something worse. I held my cool and I knew that I could not breath like normal with the tube inserted into my lungs and I had to fight the instinct to take a deep breath. I was in that state for about 15 minutes after waking and before they took the tube out of my lungs.
A funny: with the tube in my lung, of course I could not talk. They had to have something to clip the tube onto in order to keep it in place. SO, They clipped it onto my LIP. It hurt. But I couldn't talk. I could move my arms and hands. I wanted to point to my lip, and as soon as I started to point, the nurses yelled "tie his hands down, he is going to pull the tube out!" I immediately raised my hands with an OK symbol! So they didn't tie my hands down. Next I had to get the attention of my 3 daughters and wife in the room. When living In Japan, we learned a simple hand motion that meant "Come Here". I did that. One daughter caught it and said "Who". I pointed to Linda (LOML). She came, took my hand and I pinched the fire out of her hand. She screamed "OUCH, He pinched me hard". I nodded my head and pointed to my lip. Another daughter asked "IS that clip pinching your lip?" I nodded yes! They asked the nurses to take the clip off. They said "In a few more minutes, we still have a few things to get ready before taking the tube out of the lung. That seemed like an hour, but was only about 10 more minutes!
Your doctor's procedure might be different than mine though.
