We have a Clarus Levitan in the ER and it's a great tool for anatomically challenging anterior airways, cervical fusion, s/p ACDF, limited neck mobility, etc.. It's shorter than the Shikani which makes it easier to use in conjunction with traditional DL. With the Shikani, you've got this gigantic fencing foil and your body position looks like a Tai Chi pose. It's easier to just use the Levitan in place of an ETT stylet because you don't hav to crank your hand back as far and can go from direct line of sight to the video stylet, pull the blade out and just drive from there. It wouldn't be my first choice with a variceal bleed or heavy gastric contents/secretions because it's easy for your vision to become obscured, even with adequate suction. I'd probably reach for a glide or McGrath in those cases before I'd go for the video stylet.
My main complaints with the device lie in the prep time where you need to trim the ETT to 28cm. (Unlike the Shikani) That's probably not as big a deal to you guys who often are already prepped in advance or have more time to set up. As an ER doc, usually when I'm going to need it, I need it 5 minutes ago and it's precious moments lost that I'm spending cutting off a few CM of the ETT prior to loading it on the stylet. If I've got time then it's not as big a deal but I still find it annoying. I'm probably in a minority. I think you can buy certain ETT at 28cm but I haven't gone through the trouble researching/buying them.
