Sedated patients hear speech

10th October 2007

Experts carrying out research into the brain’s response to speech when under sedation has uncovered evidence which may influence the amount of anaesthetic given to patients undergoing surgery.

The Cambridge University scientists used brain imaging to find the evidence, which they say revealed reduced activity in areas critical for memory and understanding language. The aim of the study was to show how the brain’s response to speech changed as people became more sedated. It may now also affect attitudes to patients in a coma or vegetative state.
