Auditory evoked potentials for monitoring during anaesthesia: a study of data quality
Significance of output:
Approximately 1 in 550 patients experience some form of awareness during surgery. A claim for surgical awareness costs around £25000 (Sandin,R.H. 2000). However, there is no established measure for detecting awareness, resulting in high hospital drug costs, risk to patients, and trauma. Considerable research has explored the use of the brain response to sound to indicate awareness, but data quality has been poor. This study demonstrates that data quality can be improved using advanced stimulation methods developed in house, leading to potentially lower incidences of awareness. This paper was funded by £156k EPSRC grant EP/D505593.
