I used to think this way as well, until I had an epiphany and realized that I don’t wring my hands and worry about paralysis and the reversal of it, bucking on a tube, etc for a routine procedure like a lap appy or a lap chole - why should I suddenly start worrying about these things for a shoulder scope? It took one or two questionable LMAs with hypoventilation etc in the sitting position for me to think “I’m too old for this ****” and decided to intubate everyone going forward. And to be clear, I don’t use narcotics either during the procedure (the 25-50 mcg of fentanyl I give for the block is still in effect during intubation). Not saying you can’t do it with an LMA — I just don’t want that kind of stress in my life.
