The goal of this study was to synthesize evidence regarding the efficacy of inhalation aromatherapy in patients undergoing cardiac surgery.
We conducted an electronic search of four authentic databases. Randomized controlled trials (RCTs), which compared inhalation aromatherapy versus control in patients undergoing cardiac surgery, were included. Data were extracted from eligible studies and pooled in a meta-analysis model. We sought to evaluate anxiety, pain, stress, and vital signs including heart rate, systolic and diastolic blood pressure.
Nine RCTs were included in this study with a total of 656 patients. Our analysis showed inhalation aromatherapy was significantly effective in reducing anxiety (MD= -3.11, 95 % CI [-5.26, -0.96], p = 0.005), and pain (MD= -0.83, 95 % CI [-1.59, -0.07], p = 0.03) in patients undergoing cardiac surgery. Additionally, inhalation aromatherapy significantly reduced heart rate compared to control group (MD= -5.49, 95 % CI [-9.07, -1.81], p = 0.003). However, no significant differences were found between both groups in mental stress, systolic and diastolic blood pressure.
Inhalation aromatherapy administration especially with lavender can significantly reduce anxiety, pain, and heart rate in patients performed cardiac surgery. However, it is not associated with significant differences in systolic and diastolic blood pressure. Further studies are needed to confirm our results.
本研究旨在综合评估吸入芳香疗法在心脏手术患者中的疗效。
我们对四个真实数据库进行了电子检索。纳入了比较吸入芳香疗法与心脏手术患者对照组的随机对照试验（RCT）。从合格研究中提取数据，并在荟萃分析模型中进行汇总。我们旨在评估焦虑、疼痛、应激以及心率、收缩压和舒张压等生命体征。
本研究共纳入 9 项 RCT，总计 656 例患者。我们的分析表明，吸入芳香疗法可显著降低心脏手术患者的焦虑（MD=-3.11，95%CI[-5.26，-0.96]，p=0.005）和疼痛（MD=-0.83，95%CI[-1.59，-0.07]，p=0.03）。此外，与对照组相比，吸入芳香疗法可显著降低心率（MD=-5.49，95%CI[-9.07，-1.81]，p=0.003）。然而，两组间在心理应激、收缩压和舒张压方面无显著差异。
吸入芳香疗法，特别是薰衣草吸入疗法，可显著降低心脏手术患者的焦虑、疼痛和心率。然而，它与收缩压和舒张压无显著差异相关。需要进一步的研究来证实我们的结果。
