Does anyone here have a LMA time limit? Say if you were to do a six hour case, would you use a LMA? What reason do you have to have a time limit or not have one? There are I believe two case reports of uvular/small palate ischemia with LMA usage for prolonged periods. I used to not use the LMA on cases longer than three hours but have loosened my stance on this. I just want to make sure I am not missing the boat as far as the literature is concerned.
