    AbstractThere is no difference in between-patient variability of concentrations when comparing propofol and sevoflurane titrated to a bispectral index of 40-60. There is about a 300% variation in hypnotic concentration between the bottom 5% and top 5% of the population. Anaesthesia titration cannot be based solely on measured or estimated drug concentrations.Copyright © 2023 British Journal of Anaesthesia. Published by Elsevier Ltd. All rights reserved.
