NURS 202 Chapter Notes - Chapter 11: Nerve Conduction Study, Neuropathic Pain, Visceral Pain
Document Summary
Pain: unpleasant sensory and emotional experience associated with actual or potential tissue damage: highly complex and subjective experience that originates from the cns or pns, or both. Sources of pain: nociceptive pain: caused by tissue injury; develops when nerve fibres in the peripheral and central nervous systems are functioning and intact. It implies an abnormal processing of the pain message due to an injury of the nerve fibres. It is sustained on a neurochemical level that can only be identified by electromyography and nerve- conduction studies: referred pain: originates in one location but is felt at another site. Both sites are innervated by the same spinal nerve, and it is difficult for the brain to differentiate the point of origin. It results from abnormal processing by pain fibres from peripheral or central sites and does not stop when the injury heals. The level of pain intensity does not reflect the physical findings. To assess chronic pain or problematic acute pain:
