To establish whether positive suggestions given to a patient under general anaesthesia reduce postoperative pain and analgesic requirements.
Prospective double blind randomised study.
Operating theatre and gynaecology ward of a teaching hospital.
63 Woman undergoing elective abdominal hysterectomy were randomised to be played either a tape of positive suggestions or a blank tape during the operation through a personal stereo system.
Three women were withdrawn from the study. Anaesthesia was standardised for all of the women. Postoperative analgesia was provided through a patient controlled analgesia system for the first 24 hours. Pain scores were recorded every six hours.
Morphine consumption over the first 24 hours after the operation; pain scores.
Mean morphine requirements were 51.0 mg (95% confidence interval 42.1 to 60.0 mg in the women played positive suggestions; and 65.7 mg (55.6 to 75.7 mg) in those played a blank tape. The point estimate (95% confidence interval) for the difference of means was 14.6 mg (22.4%) (1.9 (2.9%) to 27.3 mg (41.6%] (p = 0.028). Pain scores were similar in the two groups.
Positive intraoperative suggestions seem to have a significant effect in reducing patients' morphine requirements in the early postoperative period.
确定在全身麻醉下给予患者积极暗示是否能减轻术后疼痛并减少镇痛药物需求。
前瞻性双盲随机研究。
一家教学医院的手术室和妇科病房。
63例行择期腹部子宫切除术的女性患者被随机分为两组，在手术过程中通过个人立体声系统分别播放积极暗示的录音带或空白录音带。
三名女性退出研究。所有女性的麻醉方法均标准化。术后前24小时通过患者自控镇痛系统进行镇痛。每6小时记录一次疼痛评分。
术后首24小时内吗啡的用量；疼痛评分。
播放积极暗示录音带的女性患者平均吗啡需求量为51.0毫克（95%置信区间为42.1至60.0毫克）；播放空白录音带的女性患者平均吗啡需求量为65.7毫克（55.6至75.7毫克）。两组均值差异的点估计值（95%置信区间）为14.6毫克（22.4%）（1.9（2.9%）至27.3毫克（41.6%））（p = 0.028）。两组的疼痛评分相似。
术中给予积极暗示似乎对降低患者术后早期的吗啡需求量有显著效果。
