9 Questions
Which of the following is true regarding the effect of epidural block on cerebral blood flow (CBF)?
CBF is autoregulated and not usually affected by epidural block.
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.
Which of the following is true regarding the effect of higher-concentration local anesthetics (LAs) on MAC-sparing effect?
Higher-concentration LAs contribute to a greater MAC-sparing effect.
Which of the following is true regarding the effect of opioid adjuvants on epidural block?
Opioid adjuvants improve postoperative pain scores but have no effect on volatile agent requirements.
Which of the following is true regarding the effect of lidocaine epidural anesthesia on MAC of sevoflurane?
Lidocaine epidural anesthesia decreases MAC of sevoflurane by up to 50%.
Which of the following is true regarding the effect of neuraxial anesthesia on anesthetic requirements?
Neuraxial anesthesia reduces anesthetic requirements.
Which of the following is true regarding the correlation between sensory nerve block and sedation level?
Block of middle thoracic dermatomes results in greater sedative effects compared to block of lower lumbar segments.
Which of the following is true regarding the effect of epidural block on volatile agent requirements?
Epidural block decreases volatile agent requirements.
Which of the following is true regarding the effect of lidocaine epidural anesthesia on hypnotic requirements?
Lidocaine epidural anesthesia decreases hypnotic requirements.
