Experiences during anaesthetic-induced unresponsiveness and NREM sleep stages
In Experiment 1, 80.0% of dexmedetomidine-receiving and 73.7% of propofol-receiving participants recalled experiences (i.e. produced content reports) at least once (difference 6.3%; 95% CI −20.1% – 32.8%). Of the 76 interviews, 69.7% included content from the unresponsive period (for details, see Prevalence of recalling experiences from anaesthetic-induced unresponsiveness (Experiment 1) and non-rapid eye movement sleep (Experiment 2). ∗Differences were not observed in drug plasma concentrations measured immediately before the interview (UR1, UR2, and R3 states combined) between those who reported no recall or content reports in either dexmedetomidine (Differences in recalling experiences were not observed between drugs in different unresponsiveness periods (UR1 FET
