METHODS: A pre-test/post-test quasi-experimental study.
METHODS: Subjects (N = 60) were older adults in the colonoscopy unit and divided into experimental (n = 30) and control groups (n = 30). The subjects in the experimental group listened to the white noise via binaural headphones for 20 minutes, while the control group received routine pre-endoscopic care. State anxiety and vital signs were assessed before and after intervention using the State-Trait Anxiety Inventory and vital signs monitor, respectively. The data were analyzed using SPSS-25 software.
RESULTS: No statistically significant differences were found between the two groups on demographic characteristics, state-anxiety, systolic and diastolic blood pressure, pulse rate, and respiratory rate before the intervention (P > .05). A significant difference was found between the experimental and control groups in terms of state-anxiety (P = .00) and pulse rate (P = .003) after the intervention. No significant differences were found between the two groups in terms of systolic blood pressure (P = .69), diastolic blood pressure (.59), and respiratory rate (P = .164) after the intervention.
CONCLUSIONS: This study provides preliminary evidence supporting the use of white noise in older adults undergoing colonoscopy to reduce anxiety. The authors recommend that this intervention, as a nonpharmacological and easily administered approach, is adopted to reduce precolonoscopy anxiety. Continued investigation into the effect of white noise on vital signs is recommended.
方法:前测/后测准实验研究。
方法:受试者(N=60)是结肠镜检查单元中的老年人,分为实验组(n=30)和对照组(n=30)。实验组受试者通过双耳耳机听白噪声20分钟,对照组接受常规内镜前护理。使用状态-特质焦虑量表和生命体征监测器评估干预前后的状态焦虑和生命体征。分别。数据采用SPSS-25软件进行分析。
结果:两组在人口统计学特征上无统计学差异,状态焦虑,收缩压和舒张压,脉搏率,干预前的呼吸频率(P>0.05)。干预后,实验组和对照组在状态焦虑(P=.00)和脉搏率(P=.003)方面存在显着差异。两组在收缩压方面无显著差异(P=0.69)。舒张压(.59),干预后的呼吸频率(P=.164)。
结论:这项研究提供了初步证据,支持在接受结肠镜检查的老年人中使用白噪声来减轻焦虑。作者建议这种干预,作为一种非药物和易于管理的方法,是为了减少结肠镜前检查的焦虑。建议继续调查白噪声对生命体征的影响。
