Neuromuscular blocking agents such as succinyl choline, gallamine, and pancuronium are not anesthetic agents and are not to be used alone for surgical restraint. 

They can be used for surgery only in conjunction with drugs known to produce adequate anesthesia / analgesia.

The use of a neuromuscular blocking agent in an animal manipulation will require a justification with extensive detail on the instrumentation / procedures used for determining that adequate anesthesia/analgesia is maintained.
