Objective: To examine the effects of music therapy on anxiety, physiological responses, and weaning parameters in patients during weaning from mechanical ventilation. Design: A repeated measures experimental design with random assignment. Population and Sample: Purposive sampling was used to recruit 20 patients during weaning from mechanical ventilation in three intensive care units of a university hospital in Bangkok, Thailand from July 2002 to February 2003. Outcome Variables: (a) the anxiety level assessed by the Numerical Rating Scale (NRS) of Anxiety Measurement; (b) physiological responses including heart rate, respiratory rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP); and (c) weaning parameters including oxygen saturation, tidal volume, and rapid shallow breathing index. Methods: Each patient was randomly assigned for a sequence of manipulation (control/intervention or intervention/control) with a 3-hour interval. The intervention included a 30-minute self-selected natural music. The control condition included a 30-minute uninterrupted rest period without music. The anxiety level, tidal volume, and rapid shallow breathing index were measured before and immediately after the manipulation. Heart rate, respiratory rate, SBP, DBP, MAP, and oxygen saturation were measured every 5 minutes, from at 5 minutes before the manipulation to at 10 minutes after the manipulation ended, except blood pressure parameters, which were measured every 10 minutes instead. Findings: The mean change in the anxiety level, respiratory rate, and MAP of the subjects in the music therapy period showed a significant, greater decrease than those in the control period. However, the mean change of heart rate, SBP, DBP, oxygen saturation, tidal volume, and rapid shallow breathing index showed a non-significant difference between the two periods over time. Conclusion: This study revealed that the music therapy could reduce anxiety, mean arterial pressure, and respiratory rate in patients during weaning from mechanical ventilation.
