Figure 1: (a) Mean heart rate values in the groups S (bupivacaine) and SD (bupivacaine + dexmedetomidine). Diamonds indicate time points of a statistically significant difference (P < 0.05) when the groups were compared. Triangles indicate very significant difference (P < 0.001). (b) Mean systolic (SBP) and diastolic (DBP) arterial pressures for the groups S (bupivacaine) and SD (bupivacaine + dexmedetomidine). Diamonds indicate the time points of a statistically significant difference (P < 0.05). Triangles indicate very significant difference (P < 0.001)
