Block-dependent sedation during epidural anaesthesia is associated with delayed brainstem conduction Doufas A.G. , Wadhwa A. , Shah Y.M. , Lin C.-M. , Haugh G.S. , Sessler D.I.

Fig 1 Level of sedation, expressed by (a) verbal rating sore (VRS), and (b) bispectral index (BIS), as a function of the sensory block. The latter was categorized in 5-dermotome groups. Data are presented as means with 95% confidence intervals.

Fig 2 Latencies of I, III, and V BAEP for each volunteer at baseline (No block) and maximum block extension (Maximum block) during the trial. If ‘Maximum block’ was maintained for more than one assessment, the latency data were averaged within the volunteers. Pseudo-paired t-test showed a significant increase only in the latency of wave III (*P=0.015).
