Somatosensory evoked potentials in deep hypothermia.
Treatment with general anesthesia (neuroleptanalgesia) and deep hypothermia was performed on 8 patients suffering from epilepsy. The body temperature was decreased to 29 degrees C and the temperature in the brain ventricles to 16 degrees C. Somatosensory evoked potentials were recorded. Increase in latency of all waves was observed, and it was noted that the more distant the wave, the higher the increase in latency. Statistical values are given for N1, N2 and N3. A parallel decrease in the amplitudes of all components of the somatosensory evoked potential was also present.
