  • Epidural block generally decreases CBF.
  • CBF is always increased by epidural block.
  • CBF is only affected by epidural block if the block is performed at the lumbar level.
  • CBF is autoregulated and not usually affected by epidural block. (correct)

Which of the following is true regarding the relationship between the level of sensory nerve block and sedation level?

  • The lower the level of sensory nerve block, the lower the sedation level. (correct)
  • The level of sensory nerve block has no effect on sedation level but only on anesthetic requirements.
  • The higher the level of sensory nerve block, the lower the sedation level.
  • There is no correlation between the level of sensory nerve block and sedation level.

Which of the following is true regarding the effect of higher-concentration local anesthetics (LAs) on MAC-sparing effect?

  • Higher-concentration LAs actually decrease MAC-sparing effect.
  • Higher-concentration LAs have no effect on MAC-sparing effect.
  • Data are insufficient to determine the effect of higher-concentration LAs on MAC-sparing effect.
