Lufthansa has a really great kit to deal with agitated passengers, but nothing to deal with pain. Air Canada's kit is pretty worthless. Most airlines fall in between.
That being said, I find the doctor's requirement a bit unrealistic.
Airways ? Common, good luck placing an airway in the cramped flight conditions. A BVM [1] would be more useful.
IVs ... Completely useless, too. First, unless you have a good nurse on board, you wont be able to open up a good vein. Second, you cannot expect airways companies to store enough of IV fluids to make a difference either way. Third, fluids don't save lives unless you have other medications coming in the next few minutes.
The lack of nitro might be a good thing too. Rarely useful, and most likely to result in the passenger passing out/dying than helping anyone.
