This "bring them into the decision-making process" is what sunk American medicine, but now it's too late to fix all that PC. Now midlevels expect to be taught what they haven't yet stolen from us. We are all a big happy family...
Never forget: they don't know what they don't know, and even the most experienced ones will give you some bad surprises, if you work enough with them. Watch them like a hawk, just don't micromanage them. Pick your battles, perfect patient care be damned. This is not solo anesthesia, and neither is the quality; learn to live with it. It's the difference between the Ritz and Hampton Inn (or Ramada, occasionally). Try to focus on the big picture and on the stuff you enjoy, to rationalize why you're doing this ****. ("I get to do many more cases, and gain more experience, and do more procedures, and blah-blah-blah, than the stool sitting mommy-track loser anesthesiologists.")
Just make sure they always feel comfortable calling for help. Don't give them a hard time even for the stupidest question. The more they call/text, the safer you'll be. You are there to be a "resource" for them (that's how the PC leadership will say), not to supervise/direct them (which is what you and the malpractice jury would say).
Don't forget to be nice, be nice, be nice to them... Treat them as if they were your boss's favorite children, because they are (even if he tells you otherwise). Spoil them, and they'll love you. You'll feel dirty and used, but you can't have everything. At least you have a job.
If you know your stuff, they'll figure it out, sooner or later. Just don't give them a hard time. First impressions, remember? Plus they are nurses, as in mob mentality: you piss off one, you piss off all.
