We studied the use of intraoperative tape suggestion to improve the rate of cessation of smoking in 363 smokers who wanted to stop smoking. They were allocated randomly to hear a taped message encouraging them to stop smoking or to a blank tape, played during general anaesthesia. Overall 56 patients (15.4%, 95% confidence interval (CI) 11.7-19.1%) had claimed to have stopped smoking at 2 months and 29 patients (8.0%, 95% CI 5.9-10.1%) were confirmed to have stopped smoking at 6 months. There was no significant difference between the groups at either 2 or 6 months (risk ratios 1.06 and 1.09, respectively, P = 0.78). A preoperative:postoperative ratio of a visual analogue scale measuring the patient's motivation to stop smoking was not significantly different (control group 1.13 vs message group 1.10, P = 0.55). This study does not support the hypothesis that intraoperative tape suggestion can change smoking behaviour.
我们对363名想要戒烟的吸烟者进行了研究，探讨术中播放录音提示对提高戒烟成功率的作用。他们被随机分为两组，一组在全身麻醉期间收听鼓励戒烟的录音信息，另一组收听空白录音带。总体而言，56名患者（15.4%，95%置信区间[CI] 11.7 - 19.1%）声称在2个月时已戒烟，29名患者（8.0%，95% CI 5.9 - 10.1%）在6个月时被证实已戒烟。两组在2个月或6个月时均无显著差异（风险比分别为1.06和1.09，P = 0.78）。测量患者戒烟动机的视觉模拟量表术前与术后的比值也无显著差异（对照组为1.13，信息组为1.10，P = 0.55）。本研究不支持术中录音提示可改变吸烟行为这一假设。
