Depth of anaesthesia

The Primary ( ) and Final () FRCA examinations require an extensive knowledge of the techniques available for monitoring the depth of anaesthesia. We have therefore written a new educational resource on this subject. The tutorials have been tailored to the FRCA syllabus and we have also added some past questions relevant to these topics.
