A technique for monitoring evoked potentials during scoliosis and brachial plexus surgery.

摘要

A total of 40 patients undergoing scoliosis or brachial plexus surgery had bipolar electrodes inserted preoperatively in the cervical epidural space located by the 'hanging drop technique'. The angle of approach to the space was different for each spinal interspace used. Good quality recordings were obtained of SSEPs with no long-term complications and we recommend this as a safe technique.
