Thank you Daniel.
This is an excellent summary and hits home with my experience almost to the
And this is my sense of IN ketamine without the experience.
Low dose is ineffective for decent sedation but might provide some pain
relief. But does it do anything better than fentanyl.
Ditto midazolam. Which I love. I am using it more and more. To calm
agitated asthmatics who don't love the mask. For UA catheterizations on
kids old enough to remember (e.g. 15 minutes). Lac repairs.
And IN ketamine is full procedural sedation, regardless of the dose.
So all of the headache with a variable, inconsistent result that could be
achieved with other IN agents.
It is perhaps a solution without a need?
