I read it as At The Lip. In some places there is a joke about ATT or At the Tooth but you might have to be from there to see the humor. This is why it is good not to use abbreviations between different agencies. This little piece of information could be a headache in a pt like this where airway is important especially as the lip swells.
Guess we'll have to see see how the author of this senario meant it.
Is there a place for introductions? I don't want to sidetrack a good discussion. I think I am only allowed 2 posts and this is it for the night.
