The BAR Monitor was used on patients undergoing elective first-time coronary artery bypass graft surgery. Patients received propofol for anaesthesia induction and were randomised to receive a low or moderate dose of the analgesic fentanyl. In this trial, the BAR monitor demonstrated the potential to monitor the level of hypnosis following anaesthesia induction with propofol via the CCS index and to facilitate the titration of fentanyl as a component of balanced anaesthesia via the CI index.
