man, you really like to split hairs.
so, since we're splitting hairs, what are we talking about here? the person who c/o sore throat immediately post-op? or, the one who complains a day or two later? is the anesthetic procedure always to blame for a post-op sore throat?
iow, do you request that your outpatient anesthetics come back for a post-op check? you're not suggesting that, are you? or, i guess you do 100% follow-ups 100% of the time. (in which case i'd call you a liar.)
and, smaller tubes? pray, do tell what you mean by that. is your intubation technique so bad that you always have to use a 5.5 or 6.0 to prevent a "sore throat"? maybe i'm just a better anesthesiologist, but i rarely get this complaint. maybe my "injury" rate is lower because i'm more gentle. and, fwiw, i rarely use LTA.
