Precedex is probably better described as an alternative to sedation, as it's purpose is to give something that can keep patients calm that can continue through extubation rather than have to be weaned prior to extubation. It's intended use is to help open heart patients through the waking-up-but-still-intubated portion of their recovery. Typically, I don't give post open hearts any sedation prior to extubation, only analgesia, our goal is a RASS of 0. When I do need to sedate an OHS patient prior to extubation, precedex can sometimes negate the need for sedation, although it's effect seems to vary widely from patient to patient, with some patients showing no apparent effects even at high doses.
When it first came out, we tried it on everyone and basically found it wasn't all that useful and certainly isn't something that can be used in place of actual sedation.
Propofol is almost always our first choice, but fentanyl and Versed drips are also used. A lot depends on how long you expect to need sedation, and if analgesia is also required-(thus the fentanyl). Advantage of propofol- short acting, less resp depression, and easily titrated. The problems are "Diprovan drooling"-massive oral secreations, propofol fever- it always seems to happen after 24-48hrs after milk of amnesia is started, and the potential for line infections-propofol makes a great culture medium for lots of hungry bugs. After reading the posts about Precedex, I'm glad we don't keep it in formulary- it sounds pretty sketchy for me to depend on it to keep my aggitated patients ETT/a-Line in place.
Precedex is not intended to be the sole drug for sedation when used for longer term (not immediately prior to extubation). By using precedex in addition to another sedative, the amount of that sedative can typically be reduced significantly (sometimes by 50-75%) to the point where the pt can be interactive with their surroundings. This info came from several inservices from a drug rep for precedex as well as personal experience.
I've found it to be very effective if combined with fentanyl or versed pushes or low dose fentanyl or propofol drips. Also very useful to "chill out" the non-intubated ETOH withdraw pts. The only complaint I have about it is the bradycardia that it can cause.
Propofol for short term sedation, midazolam for long term sedation. I HATE dexmedetomidine. 99% of the time the way it is prescribed is not the way the drug is meant to be used (eg., is written up instead of propofol for a neuro patient trying to rip every tube and line out with no plans for extubation), and I find the bradycardia it causes even at tiny doses to be very disturbing - you can't even have it running at an effective dose due to the side effects. Hate it!!
We are level 1 trauma, and usually use Propofol, in conjunction with a fentanyl CADD for pain. Occasionally if the fentanyl alone achieves a RASS of 0 or -1, we'll skip the sedation and just use the CADD (especially in the elderly.) 2nd line drug in our facility is Versed, again with a CADD. We have Precedex, and in the year and a half I've been there I've never used it myself. I think I've heard of one or two other pts being on it during my shifts.
The nice thing about propofol is it can be weaned so quickly. The pt can wake up soon after we pause it--say we're not sure if they're having neuro changes or are just oversedated. Or if the neurosurg resident shows up for early a.m. rounds at an odd time, we can wake the pt up for the resident to do his/her own exam.

What is your ICU sedation med of choice? Our Critical Care Surgery team is turning to precede almost exclusively and it makes me cringe! It works on some patients but others it doesn't work on and is never going to work on!!
one of the residents was telling me that all level 1 trauma hospitals are basically exclusively using preceded for sedation now.
