Objective: To examine the effect of patient-selected music intervention during daily weaning trials for patients on prolonged mechanical ventilation.
Design: Randomized crossover repeated measures design.
Setting: Long-term acute care hospital.
Patients: Patients on mechanical ventilation for ≥ 4 days undergoing daily weaning trials.
Intervention: Patients were randomized to patient-selected music vs no music on the first day of the intervention; provision of music was alternated for 6 days, resulting in 3 music and 3 no music days for each patient. During weaning trials on music days, data were obtained for 30 minutes prior to music listening and continued for 60 minutes while patients listened to selected music (total 90 minutes). On no music days, data were collected for 90 minutes.
Measurements and Main Results: Outcome measures included heart rate (HR), respiratory rate (RR), arterial oxygenation (SpO2), blood pressure (BP), dyspnea and anxiety assessed with a visual analog scale (VAS-D, VAS-A) and daily weaning duration (hours). Of 31 patients enrolled, 23 completed the 6-day intervention. Patients were 61.6 ± 10.9 years of age, 74% male, and 96% white. A multivariate mixed-effects model analysis demonstrated significant decreases in HR, RR, VAS-A, and VAS-D and a significant increase in daily weaning duration on music days (p<0.05).
Conclusion: Providing patient selected music is a simple, potentially beneficial intervention for LTACH patients during daily weaning trials. Further study is indicated to test ability of this intervention to promote weaning success in LTACH patients and benefits earlier in the weaning process.
