Effect of clonidine on the cutaneous silent period during spinal anesthesia

Figure 2 The differences in the dynamics of (A) heart rate (beats per min) and (B) mean arterial pressure (mmHg) between the test groups (levobupivacaine - clonidine or levobupivacaine group) and the times (min) of the measurement before and after intrathecal administration of the solutions according to the analysis of a variance for repeated measures (0 indicates the initial values before performing subarachnoid block). Error bars represent mean values (95%CI). HR: Heart rate; MAP: Mean arterial pressure.
