Relief of Procedural Pain in Critically Ill Patients by Music Therapy: A Randomized Controlled Trial

This study aimed to determine the effectiveness of music listening for procedural pain relief using two different observational pain tools during endotracheal suctioning.

This study was a randomized controlled trial. The sample of the study included 98 patients with mechanical ventilation support who met the selection criteria. The patients were randomly assigned to control and music therapy groups. Patients in the control group were routinely suctioned as usual. Patients in the music group received music therapy 20 min before, during, and 20 min after endotracheal suctioning. The primary outcome was the pain relief during suctioning.

Forty patients in each arm completed the study. Pain scores in the Critical Care Pain Observation Tool and Behavioral Pain Scale were lower in the music group than in the control group during endotracheal suctioning (group: F = 14.85, p = 0.000; F = 9.04, p = 0.000, respectively). It was also found to be a significant interaction effect between the groups and time (group × time: F = 17.35, p = 0.000; F = 18.00, p = 0.000, respectively).

The Critical Care Pain Observation Tool and Behavioral Pain Scale in the current study generally demonstrated similar pain scores during the painful procedure. Our findings support that music therapy may act as a nonpharmacological therapy to relieve procedural pain in patients on mechanical ventilation.
