"Jeez, I bet that hip is dislocated," you say to yourself. You talk with the patient, briefly examine him and put in orders for pain medications and x-rays. You complete your exam fortunately not finding any other signs of significant trauma and walk over to the radiology tech room to get an early peak at the film as it's being developed.

Now what? You know you're going to need to reduce this dislocation, to not do so would risk avascular necrosis. Tammy, one of the nurses you are working with that day is already 2 steps ahead of you. "Doc, we're getting everything set up for the sedation, you're going to need for that hip that's out. What drugs do you want us to pull up?"

You ponder the possibilities. Versed and fentanyl would probably work, but always seems to take forever. Etomidate is fast for sure but you get twitchy just thinking about that last patient who had myoclonus with it. Propofol is a newer drug to your department and has seemed to work well. But then you also wonder whether ketamine might do the trick? What about ketafol - ketamine and propofol? Is there one agent that's better then the rest? Is any one agent really superior?
