This study was conducted to determine the effects of lavender oil on the levels of anxiety and vital signs in benign prostate hyperplasia patients (BPH) in their preoperative period.
This was a quasi-experimental study and a pretest-posttest design with a control group. The population of the study consisted of elderly male patients who were hospitalized at the urology clinic of a hospital in Turkey, eligible for inclusion, and who were scheduled to undergo BPH surgery. These patients had a prostate mass >30 g on which medical treatment and minimal surgical treatment had not been succesful but which could be cured through open prostatectomy surgery and transurethral resection of the prostate. The sample consisted of 110 patients selected by the convenience sampling method and determined based on power analysis.
According to data analysis, both groups showed significantly reduced anxiety after the smelling lavender oil. However, the experimental group reported a significantly higher decrease in anxiety [mean change: -38.47 (SD 8.68) vs -2.78 (SD 3.27)] in comparison to the control group (p < 0.001). The posttest mean vital signs of the groups were compared and there was a statistically significant decrease in respiration and increase in oxygen saturation (p < 0.05).
The findings showed that lavender oil inhalation reduced anxiety levels and had effects on the vital signs of BPH patients in their preoperative period.
本研究旨在确定薰衣草油对良性前列腺增生症（BPH）患者术前焦虑水平和生命体征的影响。
这是一项准实验研究，采用前后测设计，并设有对照组。研究对象为土耳其一家医院泌尿科诊所住院的、符合纳入标准的老年男性患者，他们计划接受 BPH 手术。这些患者前列腺肿块>30g，经药物和微创手术治疗无效，但可通过开放性前列腺切除术和经尿道前列腺切除术治愈。样本由便利抽样法选择的 110 名患者组成，并根据功效分析确定。
根据数据分析，两组在闻薰衣草油后焦虑均显著降低。然而，实验组报告的焦虑降低幅度明显更高[平均变化：-38.47（SD 8.68）比-2.78（SD 3.27）]，与对照组相比差异具有统计学意义（p<0.001）。比较两组的生命体征后发现，呼吸频率显著下降，氧饱和度显著升高（p<0.05）。
研究结果表明，薰衣草油吸入可降低 BPH 患者术前的焦虑水平，并对其生命体征产生影响。
