Between 1982 and 1989 over 3000 patients were questioned about recall and dreaming after general anaesthesia for Caesarean section. Some 28 (0.9%) patients were able to recall something of their operation and 189 (6.1%) reported dreams. There was uniform adherence to a rigid anaesthetic protocol up to and including 1985, but a much publicized incident reported from the courtroom stimulated a relaxation of this regimen. Consequently the incidence of awareness decreased from 1.3% to 0.4%, and the incidence of dreaming was also reduced. Recollections of surgery were confined to manipulations, noises and voices. None of our patients complained of pain at the time of interview, although one since has. The inadequacies of the initial protocol and an approach to informed consent are discussed.
1982年至1989年间，超过3000名接受剖宫产全身麻醉的患者被询问有关术中回忆和梦境的情况。约28名（0.9%）患者能够回忆起手术中的某些事情，189名（6.1%）患者报告做了梦。直到1985年，一直严格遵循一套严格的麻醉方案，但法庭上报道的一起备受关注的事件促使该方案有所放宽。结果，术中知晓的发生率从1.3%降至0.4%，做梦的发生率也有所降低。对手术的回忆仅限于操作、噪音和声音。在接受访谈时，我们的患者均未抱怨疼痛，不过后来有一名患者抱怨了。文中讨论了最初方案的不足之处以及获取知情同意的方法。
