The objective of this study was to determine if there was a significant difference between the sleep quality of patients who inhaled placebo and those who inhaled an aroma comprising a mixture of (Lavandin Super), (bergamot), and (ylang ylang). This was a randomized, double-blind crossover study, which compared a treatment with placebo. The study was conducted in an outpatient cardiac rehabilitation unit located in an urban, private nonprofit hospital in north Texas. Participants included 42 adult patients referred to the rehabilitation service following hospitalizations by local cardiologists. Cotton balls infused with a combination of lavender, bergamot, and ylang ylang or placebo were placed at subjects' bedsides for five nights. After a washout period, subjects crossed over to the other condition for five nights. Participants completed the Pittsburgh Sleep Quality Index (PSQI) after treatment and placebo periods. Lower PSQI scores indicate better sleep quality. The mean PSQI global score was statistically significantly lower when receiving the intervention oil (mean = 4.9) than the mean PSQI global score when receiving placebo (mean = 8). Duration of sleep and the time it took to fall asleep were no different between treatment groups, but patient-reported sleep quality was significantly better when participants were exposed to essential oils (χ = 4.5, = 0.03) than when exposed to placebo. Although sleep efficiency (time asleep while lying in bed) was perceived as the same under both conditions, participants reported that they had to get up to use the bathroom significantly less often when exposed to the treatment than when exposed to placebo ( = -2.04, = 0.05; Wilcoxon = 0.05). Participants also reported that they had trouble sleeping because they felt too cold, which occurred significantly less often when exposed to the treatment than when exposed to placebo ( = -2.03, = 0.05; Wilcoxon = 0.05). Sleep quality of participants receiving intervention oils was significantly better than the sleep quality of participants receiving the placebo oil. Low-cost, nontraditional aromatherapy treatment is potentially effective for improving sleep quality among cardiac rehabilitation patients.
本研究旨在确定吸入安慰剂和吸入薰衣草、佛手柑和依兰混合物（拉文丁超级）组成的香气的患者之间的睡眠质量是否存在显著差异。这是一项随机、双盲交叉研究，比较了一种治疗方法与安慰剂。该研究在德克萨斯州北部一家城市非营利性私立医院的门诊心脏康复病房进行。参与者包括 42 名因当地心脏病专家住院而转介至康复服务的成年患者。在五个晚上，将浸有薰衣草、佛手柑和依兰混合物或安慰剂的棉花球放在受试者床边。经过洗脱期后，受试者交叉到另一种条件下进行五晚。在治疗和安慰剂期后，参与者完成了匹兹堡睡眠质量指数（PSQI）。较低的 PSQI 分数表示睡眠质量较好。接受干预油时的 PSQI 全球平均得分（均值=4.9）明显低于接受安慰剂时的 PSQI 全球平均得分（均值=8）。治疗组之间的睡眠时间和入睡时间没有差异，但患者报告的睡眠质量在接触精油时明显更好（χ²=4.5，p=0.03），而接触安慰剂时则不然。尽管两种情况下的睡眠效率（躺在床上时入睡的时间）都被认为是相同的，但与接触安慰剂时相比，参与者报告说他们在接受治疗时上厕所的次数明显减少（Z=-2.04，p=0.05；Wilcoxon Z=0.05）。参与者还报告说，他们因感到太冷而难以入睡，这种情况在接受治疗时明显少于接受安慰剂时（Z=-2.03，p=0.05；Wilcoxon Z=0.05）。接受干预油的参与者的睡眠质量明显好于接受安慰剂油的参与者。低成本、非传统的芳香疗法治疗可能对改善心脏康复患者的睡眠质量有效。
