"nociassociation = the unconscious discharge of nervous energy under
the stimulus of trauma, as in surgical shock."

This means a patient under general anesthesia can still experience
shock as a result from the nociception that results from the physical
trauma during surgery.

Just because you aren't aware of the pain doesn't mean it isn't
significantly affecting your autonomic nervous system.

Pain can kill even the the victim doesn't feel it. While may not be
felt consciously, the unconscious still feels it. As a result,
excruciating pain can screw-up the nervous system enough to cause shock
-- and even death -- even if the victim is totally unconscious.

"Physiological responses to acute pain are described, and the effects
of different analgesic techniques on these responses are discussed. The
body's response to acute pain can cause adverse physiological effects.
Pain can impede the return of normal pulmonary function, modify certain
aspects of the stress response to injury, and alter hemodynamic values
and cardiovascular function. It can produce immobility and contribute
to thromboembolic complications."

These neurophysiological effects of nociception can cause a
potentially-fatal shock reaction even if:
1. There is minimal or no bleeding
2. No infection occurs
3. The patient isn't aware of the pain
4. There is no injury to any vital organ[s]

This shock is call nociassociation and cannot be prevented even by the
most powerful general anesthetics or sedatives put together.

My point is that inducing unconsciousness might prevent the
surgery-patient from perceiving the suffering caused by his/her
injuries but that does not prevent the subconscious elements of the
nervous system from feeling the agony. The subconscious parts of the
nervous system -- which are concered with emotions and regulate the
circulatory system -- can still feel the suffering caused by the
nociception. As a result, the autonomic nervous system's control of the
heart may go awry and cause lethal cardiac arrhythmias.

This means, the subconscious parts of the nervous system must somehow
be temporarily disconnected from pain perception prior and during the
surgical operation.
