Fig 2 BIS values at different plasma propofol concentrations. Results are represented in box plot (extremes-quartiles). Awake state is before remifentanil injection. *BIS vs 2 μg ml−1, P<0.05; NS, not statistically different.

Fig 4 Change in children's position in the structured model of the MCA during decrease in plasma propofol concentration. The structure model is the same used for sevoflurane (SEVO) and desflurane (DES) in previous studies.1 4 Larger dots represent steady state. The units of axes 1 and 2 are arbitrary.
