@FFP, no one is arguing against the utility or benefits of LMA's. I am arguing though that an LMA is not a great way to go for this morbidly obese pt in T-berg coupled with controlled ventilation. The
pros you mention can just as easily be achieved with an ETT, and even if you're not some Jedi rockstar, there are times when safety should take precedence over slickness.
You say "not having to worry about ventilation/intubation" but what about when that precious iGel LMA doesn't seat quite right or the pt regurgitates mid case 'cuz her head is down and you've been slowly but surely puffing a little bit of air into her belly with each pressure
controlled breath. Yeah you got away with it, but a solid anesthetic plan never includes "I think I can get away with . . . "
