Abstract

Background: Mechanical ventilation is a lifesaving modality but is often associated with high anxiety and agitation. Agitation is associated with a longer duration of mechanical ventilation, prolonged duration of hospital and ICU stay and higher costs. Objectives: To estimate the effect of the nature-based sounds (NBS) on agitation and anxiety in patients under mechanical ventilation support. Design: randomized controlled trial. Setting: Respiratory ICU at tertiary care hospital, New Delhi. Patients: 120 patients on mechanical ventilator support. Intervention: Patients on mechanical ventilator were randomized into experimental and control group. Nature Based Sounds’ were played via media player through head phones in experimental group and control group patients were provided with headphones but without any sounds. The assessment of anxiety, agitation was done at baseline, 15th, 30th, 45th, 60th min and 30 min after the intervention (NBS). Tools: Faces anxiety scale (FAS) and The Richmond Agitation Sedation Scale (RASS) were used to assess the anxiety and agitation. Results: There was a significant reduction in the anxiety level from baseline among the subjects of experimental groups as compared to control group. (p =0.004 at 15 minutes, p=0.000 at 30 minutes, p=0.001 at 45 minutes, p=0.001 at 60 minutes and p<0.001 after 30 minutes of removal of NBS). There was a significant reduction in the agitation level from baseline among the subjects of experimental groups as compared to control group. (p =0.003 at 15 minutes, p=0.001 at 30 minutes, p=0.001 at 45 minutes, p=0.001 at 60 minutes and p=0.001 after 30 minutes of removal of Nature based sounds). Conclusion: Nature based sounds (NBS) may reduce the anxiety and agitation and heal the patients and also reduce cost of care.
