[The spontaneous and evoked EEG in anesthesia].
Clear differentiation between nociception and pain, or, better, between anti-nociception and pain relief, is essential for understanding the analgesic mechanisms in anaesthesia. Nociception is a neuronal activity in the pain-mediating and pain-processing nervous system, i.e. in the peripheral axons, in the spinal short cord and in certain brain structures. The nociceptive system has been well documented by experiments, especially in animals. ⋯ Since pain is the conscious processing of nociceptive information, attenuating the vigilance also alleviates pain; there is no pain without consciousness. Most of the centrally acting analgesics will also reduce vigilance; e.g. driving is not permitted under analgesia with opiates. Alcohol is another example, although it minimally affects the nociceptive system, it substantially lowers the vigilance, thereby alleviating pain.(ABSTRACT TRUNCATED AT 250 WORDS)
