Effect of clonidine on the cutaneous silent period during spinal anesthesia

Figure 1 Differences in duration of (A) silent cutaneous period and (B) latency of silent cutaneous period regarding the test groups (levobupivacaine - clonidine or levobupivacaine group) and the times of measurements (preoperatively, at the time point when the Bromage scale was 0, 6 h and 24 h after intrathecal administration of the solutions) according to the analysis of a variance for repeated measurements. Error bars represent mean values (95%CI). CSP: Cutaneous silent period; Preop: Preoperatively.
