术前焦虑是常见的，而且往往是严重的。门诊手术要求患者在手术后短时间内做好“街头准备”，这对我们的术前无焦虑患者目标提出了挑战。最近，已经证明，音乐可以成功地用于缓解患者在手术前的焦虑，并且嵌入有音调的音频可以在听者的大脑内创建双耳节拍，从而降低患有慢性焦虑状态的患者的主观焦虑水平。我们用状态-特质焦虑量表问卷测量焦虑，并将双耳节拍音频（双耳组）与相同的配乐（音频组）进行比较，但没有这些额外的音调（音频组），并与第三组进行比较，第三组没有接受任何特定的干预（无干预组）。双耳组焦虑评分的平均[95%置信区间]降低26.3%[19-33%]（与音频组相比p = 0.001，与无干预组相比p < 0.0001），音频组降低11.1%[6-16%]（与无干预组相比p = 0.15），无干预组降低3.8%[0-7%]。双耳节拍音频有可能显着降低急性术前焦虑。
Pre-operative anxiety is common and often significant. Ambulatory surgery challenges our pre-operative goal of an anxiety-free patient by requiring people to be 'street ready' within a brief period of time after surgery. Recently, it has been demonstrated that music can be used successfully to relieve patient anxiety before operations, and that audio embedded with tones that create binaural beats within the brain of the listener decreases subjective levels of anxiety in patients with chronic anxiety states. We measured anxiety with the State-Trait Anxiety Inventory questionnaire and compared binaural beat audio (Binaural Group) with an identical soundtrack but without these added tones (Audio Group) and with a third group who received no specific intervention (No Intervention Group). Mean [95% confidence intervals] decreases in anxiety scores were 26.3%[19-33%] in the Binaural Group (p = 0.001 vs. Audio Group, p < 0.0001 vs. No Intervention Group), 11.1%[6-16%] in the Audio Group (p = 0.15 vs. No Intervention Group) and 3.8%[0-7%] in the No Intervention Group. Binaural beat audio has the potential to decrease acute pre-operative anxiety significantly.
