Music to Decrease Pain and Anxiety During Head CTs Performed at the PEds ED

Anxiety Disorder of Childhood or Adolescence

A single blinded controlled trial to determine if an intervention of listening to nursery songs with integrated heart beat sounds results in changes in anxiety level in infants and young children less than four years of age in an emergent setting.

This study is a prospective cohort with a randomized single-blinded intervention with convenience sampling design. Our pediatric emergency medicine department (PED) treats nearly 2,500 patients between 1 and 3 years of age annually in 2008-10 and is a regional referral center for specialty care for our state. All data is collected in the PED between May 2008 and July 2010. One PED examination room is designated as the study room. The music was stored on an ipod played in a portable speaker. The music is from the Compact Disk(CD), Baby Go to Sleep. This is a commercially available CD.23 The Baby Go to Sleep Compact Disk played a combination of the sound of an actual human heartbeat and children's songs. Tempo changes occurred between each song. During the study, the initial three nursery rhymes were played. The principal investigator's research associates recruit all patients up to 3 years of age presenting to the PED during the hours they were available. Once situated in the room, children both in the control and experimental group received the usual medical care including the evaluation by attending physician to determine if head CT would be performed or not. After subjects were determined to need a head CT by the attending physicians, they were randomly assigned to either the Control(Con) or experimental(Exp) group. Children in the Con group received the usual medical care while children in the Exp group received the usual medical care in combination with the intervention. The intervention was started by the patients nurse without the knowledge of the research associate. In the intervention group, music was played until the CT scan was completed. Research associates rated children's anxiety levels using a visual analogue scale(VAS) and Modified Ramsay Sedation Scale(MRSS) before children were transferred to radiology department for head CT then after children was laid down to go through head CT. Researchers associates were blinded to group by wearing headphones that were tested to ensure that they could not hear whether or not music was playing during the intervention phase.
