Music has long been known to reduce anxiety, minimize the need for sedatives, and make patients feel more at ease. The purpose of the study was to evaluate the effect of music in elderly outpatients undergoing elective cataract surgery with retrobulbar block and monitored anaesthetic care using fentanyl or alfentanil and midazolam.
One hundred and twenty one patients were prospectively and randomly assigned to hear: relaxing suggestions, white noise, operating room noise or relaxing music via audio-cassette headphones. Vital signs were documented before and after retrobulbar block and every 15 min thereafter. Anxiety was assessed using the State-Trait Anxiety Inventory (STAI) before and after surgery. Visual analogue scales (VAS) were used to assess anxiety and patient satisfaction postoperatively with a standardized questionnaire. Between group comparisons were made using Chi-Square, or ANOVA, where appropriate.
There were no differences between groups in STAI or anxiety VAS scores at any time. Differences were noted in systolic blood pressure, but not in other vital signs. Patients' ratings of the whole operative experience, satisfaction with the tape played, general level of relaxation and preference for the chosen tape for subsequent surgery were different (music > relaxing suggestions > white noise and OR noise, P < 0.05).
Elderly patients undergoing cataract surgery under retrobulbar block were more satisfied with their experience if they heard relaxing music, rather than relaxing suggestions or white noise or OR noise. The type of auditory stimuli to which the patients were exposed did not influence the level of anxiety.
长期以来，人们都知道音乐可以减轻焦虑、减少镇静剂的使用，并让患者感觉更加放松。本研究的目的是评估音乐对接受球后阻滞和使用芬太尼或阿芬太尼及咪达唑仑进行麻醉监测的择期白内障手术老年门诊患者的影响。
121例患者被前瞻性随机分配，通过盒式磁带耳机收听：放松建议、白噪音、手术室噪音或放松音乐。记录球后阻滞前后及此后每15分钟的生命体征。术前和术后使用状态-特质焦虑量表（STAI）评估焦虑程度。术后使用视觉模拟量表（VAS），通过标准化问卷评估焦虑和患者满意度。在适当情况下，使用卡方检验或方差分析进行组间比较。
在任何时候，各组之间的STAI或焦虑VAS评分均无差异。收缩压有差异，但其他生命体征无差异。患者对整个手术体验的评分、对所播放磁带的满意度、总体放松程度以及对后续手术所选磁带的偏好不同（音乐>放松建议>白噪音和手术室噪音，P<0.05）。
接受球后阻滞白内障手术的老年患者，如果收听放松音乐，而非放松建议、白噪音或手术室噪音，对手术体验会更满意。患者所接触的听觉刺激类型并未影响焦虑水平。
