Subject: Some people having surgery 'feel' the operation.

I have heard that sometimes one part of the three part anasthetic can run 
out during surgery (the no feeling pain part).  If I understand correctly, 
there is a no feel part, a sleep part, and a paralyzing part (I don't know 
the proper names).  I heard that they can't tell during surgery without a 
special monitoring machine.

But I would think that even if you are paralyzed, feeling the pain would 
start an adrenalyn rush, and raise your heart rate and resparation etc.  
Wouldn't that tip of the surgeon?
