Hypothetical:

You're giving anesthesia for a surgeon who is insisting on good muscle relaxation for about the first hour of a 2-3 hour case. You have every anesthesia adjunct available to you except that you don't have any non depolarizer at all and only one dose of Anectine.

You reply with your usual "no problem" and the case goes uneventfully. What did you do?

(Profoundly deep anesthesia does not provide the required muscle relaxation).
