Figure 2.
Right hindlimb EPTs of the four groups at different time points (n=8). The times required for group R, group D1 and group D2 to return to baseline motor function were 180, 240 and 270 min, respectively. The time to return to baseline motor function was defined as P≥0.05 vs. group C. *P<0.05 vs. group C. EPT, extensor postural thrust; group R, ropivacaine group; group D1, low-dose dexmedetomidine group; group D2, high-dose dexmedetomidine group; group C, control group; group S, sham group.
