| AUC (dBs) | 131.57 ± 70.98 | 141.79 ± 96.25 | 53.72 ± 29.06 a,c) |
Data are expressed as mean ± SD (n=8). TZM, tiletamine-zolazepam-medetomidine; M, medetomidine; TTP0, time to peak enhancement from contrast injection; TTPup, time to peak enhancement from initial rise; AUC, area under the curve. a) P<0.05 (Conscious group versus M group); b) P<0.05 (Conscious group versus TZM group); c) P<0.05 (TZM group versus M group).
