I was asked a question today by PM, and answered it, but decided the info also belongs here on the open forum.

My PEG has been clogging in the outer part and I have been able to unplug it, but since it has been in for almost a year they want to replace it Monday. When they replace the PEG will they have to totally sedate me? My airway is very constricted now and they can not get the tubes down it anymore which would mean a trach. I have a call in to the doc also - but I like to be as informed as possible. I thought that you might know since you have had one switched before.

I've never had one switched (I took one out several times to clean it, but that was 'unofficial', of course!). I've had three, but they were all new from the start.

I am considering having mine switched to the Mic-Key low profile one, so I was thinking about that myself. Looking at the YouTube video, putting a Mic-Key into an existing hole seems easy, with the balloon being inflated after it's in with a syringe and water (In fact, I'll probably ask to do it myself). A lot might depend on what you have now, that is, does it have a balloon (The skinny one I had didn't; it just slid out, depending on length and some curves for retention) and whether the balloon is inflatable/deflatable (My other two have non-deflatable 'donuts' on the end and are the 'just yank it out' kind.

The Doc is going to be your best bet for that info.

If they are going to sedate you, they will have to tell you beforehand so you can arrange for someone to drive you home afterwards. In my case, the sedation was something like Rohypnol (aka Roofie) by injection by the Doc, not a full-bore anesthesiologist undertaking, however, a new placement involved an endoscope down my throat.
