The impact of listening to pleasant natural sounds on anxiety and physiologic parameters in patients undergoing coronary angiography: A pragmatic quasi-randomized-controlled trial

Abstract

Objective: This study aimed to investigate the impact of listening to pleasant natural sounds on anxiety and physiological parameters in patients undergoing coronary angiography. Methods:The present pragmatic quasi-randomized controlled clinical trial was conducted on 130 patients undergone elective angiography. The participants were randomly divided into two groups, including a pleasant natural sounds group, and a control group (n½ 65 per group).Spielberger's state/ trait anxiety inventory was used to assess levels of anxiety. The patients' anxiety level and physiological parameters were measured at baseline, before, during, immediately after, and twenty minutes after coronary angiography. Results:The mean level of anxiety was similar in both arms at baseline ‫,713.1=ݐ(‬ df=128, p= 0.190). The intervention arm displayed significantly lower anxiety levels than the control arm during the intervention (Wilks' lambda 0.11, Pillai's trace 0.89, P 0.001, F 2.05). The physiological parameters (systolic and diastolic blood pressure, mean arterial pressure, heart rate, and oxygen saturation) of both groups showed statistically significant differences (p<0.05) over time and in group-by time interactions. Conclusion:As an effective nursing intervention presenting no side-effects, listening to pleasant natural sounds can be helpful in the management of anxiety.

Effects of music therapy on anxiety and physiologic parameters in angiography: a systematic review and meta-analysis

“…Taylor-Piliae et al reported that the subjects’ cardiac disease processes were acute coronary syndrome (n=23, 51%), angina (n=20, 44%), or arrhythmia (n=2, 4%) 23. Rejeh et al reported that the average duration of heart disease in the patient population was 8.93±3.81 months; however, they did not provide a breakdown of the specific disease processes 16. Ripley et al reported that 34% of patients had a previous myocardial infarction, 44% of patients had previous percutaneous coronary intervention, and 19% of patients had had previous coronary artery bypass grafting 17.…”

“…Chang et al reported that 33.3% of the included patients used ß-blocker antihypertensive medication at baseline 21. Rejeh et al reported that patients receiving antihypertensive drugs were excluded from the study 16. No other studies provided details on patients’ preprocedural medication.…”

Therapeutic Gardens &ndash; A healing environment for optimizing the health care experience of Alzheimer&rsquo;s and dementia patients: A narrative review&nbsp;&nbsp;

“…The act of viewing nature through a window may help alleviate isolation and loneliness, which may have a positive impact on patients [52]. Similarly, studies have demonstrated that listening to soothing nature sounds such as birdsong can reduce patient anxiety and agitation [53,54]. Additionally, an environment with flowering plants, aquariums and wall murals of nature scenes will evoke positive stimuli to the senses and engender a calming effect on anxiety in dental waiting rooms and psychiatric units [55,4].…”

Nature-based supportive care opportunities: a conceptual framework

“…Currently, artificial plant representations, such as nature art [43], nature sounds [44], and nature screens [42] are permissible as nature-based interventions. While research is accumulating to raise and broaden nature's profile in healthcare, greater scrutiny is needed to substantiate causality, and greater discernment is needed to define what nature is, and is not, in the context of health intervention.…”
