The effect site compartment EC05, EC50, and EC95 (left to right along
each horizontal line corresponding to a race) propofol concentrations at loss of
consciousness for four different races. Lines A and B represent the peak ESC
concentration (0.81 and 1.63 µg/mL) predicted by the Marsh model (manual
mode, non-TCI) for a propofol bolus of 0.5 mg/kg (low end of dosing range for
sedation) and 1.0 mg/kg (high end of dosing range for sedation), respectively.
Lines C and D represent the peak ESC concentration (1.43 and 2.86 µg/mL)
predicted by the Fresenius (modified Marsh model with faster equilibration
between the plasma and effect site compartments) model (manual mode, non-TCI)
for a propofol bolus of 0.5 mg/kg and 1.0 mg/kg, respectively. Where available
or derivable, the 95%CI is also displayed. The short line in the middle
of each set is the EC value with the two shorter lines on each side representing
the 95%CI. The short vertical lines are shown as dashed lines where the
values that they represent are derived instead of being copied verbatim from the
prior studies used to create the model.
