More about pain and shockHi:
I just thought I'd include this topic.

"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 of the nociception that results from the physical
injuries that occur during the surgery. Local anesthesia *must* be
used in all surgeries!!!!
Just because you aren't aware of the pain doesn't mean it isn't
significantly affecting your emotions and autonomic nervous system.
Pain can kill even if 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.
Even during the deepest coma, emotions -- such as fear -- can remain
active, its just that the patient isn't aware of it.
Hence, when a unconscious patient is operated on, the nociception
causes pain just as it would in a conscious individual. This pain
causes tremendous emotional distress. The emotional distress causes
neurogenic shock, even though the patient is not aware of -- and does
not consciously feel -- the distress or the pain.
These psychoneurophysiological 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 or emotional distress cause by
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 consciously-perceiving the suffering caused by his/her
injuries but this does not prevent the subconscious elements of the
nervous system from feeling the agony. The subconscious parts of the
nervous system -- which are concerned with emotions and regulate the
circulatory system -- can still feel the intense emotional suffering
caused by the nociception. The extreme emotional distress caused by
the severe pain results in neurogenic shock. Nociassociative
neurogenic shock is marked by the following extreme changes in the
circulatory system:
1. Force of the heart muscles' contractions decrease significantly
2. Heart rate decreases dramatically.
3. General increase in the heart muscles' relaxability
4. Blood vessels throughout the body widen to total dilation
The above 4 conspire to cause a lethal drop in blood pressure. As a
result, vital organs are deprived of blood leading to multiple-organ-
failure. This can rapidly kill the patient.
This means, the subconscious parts of the nervous system must somehow
be temporarily disconnected from pain perception prior to and during
the surgical operation.
In order for the surgery not to result in a likely-fatal
nociassociation, the patient's entire autonomic nervous system [and
their effectors], limbic system [emotion], his/her heart's natural
pacemaker, smooth muscles, reflexes [all types; including reflexes not
involved with the autonomic nervous system], endocrine and hormonal
systems must be rendered totally unresponsive to the infliction of
even the most excruciating pain and totally unresponsive to any type
of injury.
The best way to do this is to locally-anesthetize all sensory-
receptors and sensory nerves at the site of the operation before the
surgery and make sure they are completely numb throughout the surgery
and for at least 15 minutes after the surgery is complete. After 15
minutes the sensory-receptors and sensory nerves at the affected site
should be allowed to *gradually* resume activity. It should take at
least an additional hour for these sensory receptors and nerves to
regain complete "wakefuleness". This will prevent the root-cause of
nociassociation.
Note: nociassociation is one of the major reasons that martial-arts
relies on pain-sensitive areas of the body as targets. This is how a
punch to the solar plexus can kill.
Any questions/comments are welcome
