Spinal level for discharge to the floor?

What is the discharge criteria in your PACU for discharge to the floor (not home)?

Currently,our policy is muddied to say the least,with every anesthetist having a different opinion:

-some say spinal has to be completely gone,evidenced by pt's ability to flex knee and lift hips off bed.

-others say as long as there is evidence that spinal is moving down,as evidenced by changing dermatomes,and vital signs are stable,the pt may be discharged.

The problem is that we do see hypotensive events even after the first 30 minutes,(and even after spinal is L4 or 5). We're concerned about this happening on the ward,where busy nurses, with several pts, may not pick up on it for awhile.

What are your thoughts?
Thanks!
