Anxiety is an unpleasant feeling that increases the myocardial oxygen demand in acute coronary syndrome. This study aimed to evaluate the effect of peppermint aromatherapy on anxiety in patients with acute coronary syndrome in the emergency department.
In this clinical trial study, 64 patients with acute coronary syndrome were randomly divided into intervention and control groups. In the intervention group, a cotton ball was soaked in 100% peppermint essential oil and placed about 20 cm from the patient's nose for 1 h while in the control group, the cotton ball was soaked in water. Anxiety was measured before and after the intervention with The Spielberger state-trait anxiety inventory. The data were analyzed in SPSS ver.23 software.
No significant difference was observed between the two groups in terms of patients' demographic data. The mean score of trait and state anxiety before the intervention was not significantly different between the two groups. After the intervention, anxiety was significantly lower in the intervention group (37.72 ± 10.41) compared to the control group (42.62 ± 5.99) (P = 0.021). Results indicated a significant decrease in anxiety after the intervention (P < 0.001) in the intervention group. Such a difference was not significant in the control group.
Peppermint essential oil inhalation significantly reduces anxiety of patients with acute coronary syndrome in emergency department.
焦虑是一种不愉快的感觉，会增加急性冠状动脉综合征患者的心肌需氧量。本研究旨在评估薄荷精油芳香疗法对急诊科急性冠状动脉综合征患者焦虑的影响。
在这项临床试验研究中，将 64 名急性冠状动脉综合征患者随机分为干预组和对照组。在干预组中，将一个棉花球浸泡在 100%薄荷精油中，放置在离患者鼻子约 20 厘米的地方 1 小时，而在对照组中，棉花球浸泡在水中。使用 Spielberger 状态-特质焦虑量表在干预前后测量焦虑。数据使用 SPSS 版本 23 软件进行分析。
两组患者的人口统计学数据无显著差异。干预前，两组特质和状态焦虑的平均评分无显著差异。干预后，干预组（37.72±10.41）的焦虑评分明显低于对照组（42.62±5.99）（P=0.021）。结果表明，干预组的焦虑显著降低（P<0.001）。对照组的差异不显著。
薄荷精油吸入可显著减轻急诊科急性冠状动脉综合征患者的焦虑。
