I really don't see it used except for acute pain indications due to its short duration. It only works for 15 - 30 minutes until you have to take another hit.
I see it used for line placement, pain management post-op, trauma injury, dental procedures, monitored anesthesia.
Your going to find certain hospitals use a ton of it and others rarely find it necessary. Doctors have been performing procedures a long time without it and you've got to train them on why it may be a good addition to their practice. Its one of the reasons the drug needs a strong sales team.
