Differences of T2*-oxygenation-ratio between anesthetic agents.

<p>A, cortex; B, thalamus; C, hippocampus; D, striatum. Diagrams are box plots made with IBM SPSS software. Each box plot represents median, 25^th and 75^th percentile, minimum and maximum values, outliers (°) and extremes (*). Y-axis: regional T2*-oxygenation-ratio. Compared to isoflurane: # p<0.05, ## p<0.01, ### p<0.001. Compared to sevoflurane: + p<0.05, ++ p<0.01, +++ p<0.001. Compared to midazolam: $ p<0.05, ($) p = 0.053. iso, isoflurane; sevo, sevoflurane; prop, propofol; mdz, midazolam; medet, medetomidine; ket-xyl, ketamine-xylazine. The dotted line at 50000 shows a separation between high and low T2*-oxygenation-ratio.
