If you want to wake up patients on a dime, I suggest 70% nitrous, 30mcg/kg/min and titrate remi from .1 up to .3. turn down remi to .05 10 minutes out and don't turn off anything else off until head is to you and you're ready. Patient will wake up within a minute or two vast majority of the time. I personally leave the remi at .05 during wake up, but you can turn it off when you turn everything else off. These wakeups areincredibly smooth, no bucking.
That being said, obviously expensive with the remi. Also, titrate a small amount of fent through the case, none in the last 15 or 20 minutes. And dexamethasone and zofran for PONV prophylaxis. With this, patients do fantastic and surgeons will be very happy with you.
