Etomidate In many cases will work fine alone like has been mentioned by many other replies here but paralytics are nice to have for a back up in a RSI situation,Lido jelly applied to your tube helps with numbing your vagal response,in the system that I work for we are very agressive in the manner of RSI
We carry Vec,Succ ,Versed,Etomidate,Ativan so we covered in about all situations we encounter
One thing that you do want to watch with versed if you have or will be getting it is one of the side effects is hypotension and it will cause there pressures to drop I have seen this first hand
And secondly something that you might want to discuss with your medical director is if your first dose of Etomidate does not produce the effect that your looking for is may you give a second our medical director in our system allows this
and 2 dose will usually snowball anyone
Good Luck
