Aromatherapy is a noninvasive method used for alleviating anxiety. Lemon verbena ( Paláu, LV) has been frequently used in traditional medicine as an anxiolytic agent due to its pharmacological ingredients.
This randomized controlled trial aimed to assess the effects of inhaling essential oil of LV on the level of anxiety and subsequent hemodynamic changes before cesarean section.
The recent study was a randomized single-blind trial. Participants ( = 84) were randomly divided into two groups: LV essential oil (group A) and placebo (group B). The intervention group underwent aromatherapy using three drops of LV essential oil at a distance of 10 cm for 30 min. The placebo group received aromatherapy in a similar fashion. The State-Trait Anxiety Inventory of Spielberger questionnaire was administered before and 5 min after aroma inhalation. Vital signs were recorded before and after aromatherapy. Likewise, pain severity was assessed using the Numeric Rating Scale and vital signs were recorded. Data were analyzed using -test, , and the Kolmogrov-Smirnov test through SPSS21 software.
Anxiety level was significantly attenuated in group A after aromatherapy. Heart rate, respiratory rate, and blood pressure decreased after inhalation; but no significant variation of pain scores was observed after inhalation in both groups.
We concluded that LV decreased preoperative anxiety in this recent study, therefore, aromatherapy with LV essential oil as a preemptive adjuvant to relieve anxiety before cesarean section is recommended by us; although more studies are required to endorse the results.
芳香疗法是一种用于缓解焦虑的非侵入性方法。柠檬马鞭草（Paláu，LV）因其药理成分在传统医学中常被用作抗焦虑剂。
这项随机对照试验旨在评估剖宫产术前吸入LV精油对焦虑水平及随后血流动力学变化的影响。
最近的这项研究是一项随机单盲试验。参与者（n = 84）被随机分为两组：LV精油组（A组）和安慰剂组（B组）。干预组使用三滴LV精油在距离10厘米处进行芳香疗法，持续30分钟。安慰剂组以类似方式接受芳香疗法。在香气吸入前和吸入后5分钟使用斯皮尔伯格状态 - 特质焦虑量表问卷。在芳香疗法前后记录生命体征。同样，使用数字评分量表评估疼痛严重程度并记录生命体征。通过SPSS21软件使用t检验、方差分析和柯尔莫哥洛夫 - 斯米尔诺夫检验分析数据。
芳香疗法后A组焦虑水平显著降低。吸入后心率、呼吸频率和血压下降；但两组吸入后疼痛评分均未观察到显著变化。
我们得出结论，在最近的这项研究中LV降低了术前焦虑，因此，我们建议使用LV精油进行芳香疗法作为剖宫产术前缓解焦虑的预防性辅助措施；尽管需要更多研究来证实这些结果。
