title: Effect of steady hypothermia and normothermia on multimodality evoked potentials in human poikilothermia.
abstract: OBJECTIVE
  To assess the effects of steady-state spontaneous hypothermia on multimodality evoked potentials and on peripheral nerve conduction in human poikilothermia.
  
  
  METHODS
  Case series at a university hospital.
  
  
  METHODS
  Four patients (four women, aged 28 to 37 years) with acquired poikilothermia.
  
  
  METHODS
  Short-latency somatosensory, brain-stem auditory, and visual evoked potentials as well as motor and sensory peripheral nerve conduction velocity during steady-state spontaneous hypothermia and normothermia.
  
  
  RESULTS
  The marked latency prolongation of all evoked potentials and decreased peripheral nerve conduction velocity observed during steady-state spontaneous hypothermia (mean +/- SD core temperature, 33.5 +/- 0.3 degrees C) compared with normothermia (36.9 +/- 0.4 degrees C) agrees with previous findings during short-term induced hypothermia.
  
  
  CONCLUSIONS
  The unequivocal effect of sustained mild spontaneous hypothermia on evoked potentials and peripheral nerve conduction velocity underlines the importance of meticulous attention to even small alterations in core temperature in interpreting neurophysiological investigations.
