I work in a PICU and we usually use Fentanyl and Versed for pain/ sedation while intubated, but lately we are using Precedex (dexmetatomidine) more and more. It is generally used as an adjunct though, not by itself, for particularly ballistic patients who might otherwise require really massive doses of Fentanyl and Versed to keep them "down." The only time I think we use it as a solo drug is with patients who require noninvasive ventilation (CPAP, biPAP etc), and it has really worked well for that. Cheers!
I loved when we used Propofol- it was so easy. Before that we used quite a bit of Ativan/Versed gtts. Bad thing about Ativan is that it stays so long in their system after its off and pts were going for unnecessary tests like ct scans of head/ mri's etc to check brain activity. We often use Fentanyl (for pain) with Versed and have both drips, one potentiates the effect of the other. Never used the one you spoke of but did read up on it.
