Nitrous Oxide

Location: 
Royal Melbourne Hospital, Australia

Nitrous oxide, while not potent enough to be a sole anaesthetic agent, is often co-administered with more powerful volatile agents such that the inspired concentrations of such agents can be reduced.  However the effects of nitrous oxide are poorly detected by existing electroencephalography (EEG) based methods.  This study demonstrated the BAR methodology to be more sensitive in detecting the effects of nitrous oxide than the leading existing EEG based method.
