Predictive Associations of Music, Anxiety, and Sedative Exposure on Mechanical Ventilation Weaning Trials.

ABSTRACT:

Background

Weaning from mechanical ventilation requires increased respiratory effort, which can heighten anxiety and later prolong the need for mechanical ventilation.

Objectives

To examine the predictive associations of music intervention, anxiety, sedative exposure, and patients' characteristics on time to initiation and duration of weaning trials of patients receiving mechanical ventilation.

Methods

A descriptive, correlational design was used for a secondary analysis of data from a randomized trial. Music listening was defined as self-initiated, patient-directed music via headphones. Anxiety was measured daily with a visual analog scale. Sedative exposure was operationalized as a daily sedation intensity score and a sedative dose frequency. Analyses consisted of d
