Thirty patients scheduled for elective cardiopulmonary bypass surgery were interviewed pre-operatively and postoperatively to assess changes in their emotional state and recollections, both aware and unaware, of intra-operative events. A random selection of patients heard a prerecorded audio tape towards the end of bypass after they were rewarmed to 37 degrees C. The tape contained suggestions for patients to touch their chin during the postoperative interview, to remember three sentences and to recover quickly. The interviewers were blind to the experimental condition. The experimental group touched their chins significantly more often than the control group (p = 0.015). Sentence recognition did not reach significance and this may be due to the small numbers and low salience of the stimuli. Seven patients (23%) recalled intraoperative events, five with the aid of hypnosis. Three reports (10%) were corroborated. Pre-operative medication (p less than 0.01) and postoperative anxiety (p less than 0.05) were significant predictors of those patients who reported recall.
对30例计划接受择期体外循环手术的患者在术前和术后进行了访谈，以评估他们情绪状态的变化以及对术中事件有意识和无意识的回忆。在患者复温至37摄氏度后，随机选择一部分患者在体外循环即将结束时听一段预先录制的录音带。录音带包含了让患者在术后访谈中触摸下巴、记住三句话并快速恢复的建议。访谈者对实验条件不知情。实验组触摸下巴的频率明显高于对照组（p = 0.015）。句子识别未达到显著水平，这可能是由于刺激的数量少且显著性低。7例患者（23%）回忆起术中事件，其中5例借助催眠。3份报告（10%）得到了证实。术前用药（p < 0.01）和术后焦虑（p < 0.05）是报告有回忆的患者的显著预测因素。
