The purpose of this study was to investigate whether lavender oil aromatherapy can reduce the bispectral index (BIS) values and stress and decrease the pain of needle insertion in 30 volunteers.
Thirty (30) healthy volunteers were randomly allocated to 2 groups: the experimental group received oxygen with a face mask coated with lavender oil for 5 minutes, and the control group received oxygen through a face mask with no lavender oil for 5 minutes. The stress level (0=no stress, 10=maximum stress), BIS value, and pain intensity of needle insertion (0=no pain, 10=worst pain imaginable) were measured.
There were no significant differences in age, sex, height, and weight between the two groups. Stress level, BIS value, and pain intensity of needle insertion before aromatherapy were similar between the two groups. However, the stress values (p<0.001) and BIS value (p<0.001) after aromatherapy were significantly reduced compared with the control. In addition, the pain intensity of needle insertion was significantly decreased after aromatherapy compared with the control (p<0.001).
Lavender aromatherapy in volunteers provided a significant decrease in the stress levels and in the BIS values. In addition, it significantly reduced the pain intensity of needle insertion.
本研究旨在探讨薰衣草精油香薰疗法是否可以降低 30 名志愿者的脑电双频指数（BIS）值和应激水平，减轻其针刺疼痛。
将 30 名健康志愿者随机分为两组：实验组接受涂有薰衣草油的面罩吸氧 5 分钟，对照组接受无薰衣草油的面罩吸氧 5 分钟。测量应激水平（0=无应激，10=最大应激）、BIS 值和针刺疼痛强度（0=无痛，10=可想象的最痛）。
两组间的年龄、性别、身高和体重均无显著差异。香薰疗法前两组的应激水平、BIS 值和针刺疼痛强度相似。然而，与对照组相比，香薰疗法后的应激值（p<0.001）和 BIS 值（p<0.001）明显降低。此外，与对照组相比，香薰疗法后针刺疼痛强度明显降低（p<0.001）。
志愿者接受薰衣草香薰疗法可显著降低应激水平和 BIS 值。此外，它还显著减轻了针刺疼痛强度。
