Do evoked potentials have any value in anaesthesia?

Intraoperative monitoring of sensory-evoked potential has been found to be useful in many areas, particularly during scoliosis surgery and neurovascular surgery. However, it remains a complicated technique, devoid of simple interpretation and as such cannot be considered a routine clinical monitor except in large centres with special expertise. Increase in utilization must await improvement in technique and development of strict criteria for interpretation.
