試題詳解

19. Which of the following is the unacceptable statement?
(A) The idea of pre-emptive analgesia is based on clinical observations demonstrating that if the afferent traffic of pain signals is prevented from reaching the central nociceptive neurons by preinjury administration of analgesics, sensitization of the central neurons will not take place or will be reduced.
(B) Even though there are the negative findings of clinical studies of pre-emptive analgesia, we may not discard the hypothesis that central sensitization is an important mechanism in postoperative pain
(C) Evidence from clinical studies suggests that acute, postoperative pain involves multiple mechanisms, including sensitization of peripheral and central neuronal pathway.
(D) Postoperative pain may include a combination of nociceptive, inflammatory, visceral and neuropathic pain mechanisms.
(E) If a patient records a baseline visual analogue scale score in excess of 30 mm, they would probably have recorded at least moderate pain on a four-point categorical scale.
