Complementary therapies, such as aromatherapy, were used to manage acute and chronic symptoms of diseases. Anxiety symptoms and deviations in vital signs are frequently manifest in patients admitted to the cardiac care unit (CCU). This study aimed to evaluate the impact of and chamomile aromas on anxiety levels and vital signs of patients hospitalized in CCU.
In this clinical research trial (CRT), a total of 76 hospitalized patients in the CCU were randomly assigned to two groups. The intervention group received aromatherapy using a blend of chamomile and essences at a ratio of 2:0.5 on an eye pad. They inhaled the aromas from a distance of 10 cm for three nights. Vital signs were recorded every 6 h. Spielberger's anxiety questionnaire was administered before and after the intervention. Data were analyzed using independent -tests, paired -tests, Chi-square tests, Fisher's exact tests, and the generalized estimating equation (GEE) approach.
Before the aromatherapy, the mean (SD) scores of state and trait anxiety in the intervention group were 57.9 (11.4) and 50 (12.5) respectively, after the intervention, these scores decreased to 35.3 (8.4) and 38.5 (8.2), and the paired -test revealed a significant difference between them ( < 0.001). Before the intervention there was no significant difference in the mean scores of state and trait anxiety between the two groups, ( > 0.05), however following the intervention, a significant difference was observed ( < 0.001). Additionally, the intervention resulted in the recovery of patients' heart rate.
The results showed, application of and chamomile aromas significantly lower anxiety levels and enhance the hemodynamic status of patients in the CCU. It may be suggested as a beneficial nursing intervention for these patients.
诸如芳香疗法等补充疗法被用于管理疾病的急性和慢性症状。心脏监护病房（CCU）收治的患者经常出现焦虑症状和生命体征偏差。本研究旨在评估薰衣草和洋甘菊香气对CCU住院患者焦虑水平和生命体征的影响。
在这项临床研究试验（CRT）中，共有76名CCU住院患者被随机分为两组。干预组在眼罩上使用薰衣草和洋甘菊精油按2:0.5比例调配的混合精油进行芳香疗法。他们在距离10厘米处吸入香气，持续三个晚上。每6小时记录一次生命体征。在干预前后进行斯皮尔伯格焦虑问卷测试。数据采用独立样本t检验、配对样本t检验、卡方检验、费舍尔精确检验和广义估计方程（GEE）方法进行分析。
芳香疗法前，干预组状态焦虑和特质焦虑的平均（标准差）得分分别为57.9（11.4）和50（12.5），干预后，这些得分降至35.3（8.4）和38.5（8.2），配对样本t检验显示两者之间存在显著差异（P<0.001）。干预前两组状态焦虑和特质焦虑的平均得分无显著差异（P>0.05），然而干预后，观察到显著差异（P<0.
