Effect of sleep-inducing music on sleep in persons with percutaneous transluminal coronary angiography in the cardiac care unit.

AIM AND OBJECTIVE: The study compared the effect of earplug-delivered sleep-inducing music on sleep in persons with percutaneous transluminal coronary angiography in the cardiac care unit.

BACKGROUND: Diverse types of music have been claimed to improve sleeping elsewhere, but relatively little is known in South Korea. Most studies investigating the effect of sleep-inducing music on sleep have involved persons with insomnia, even though many persons with cardiovascular disease in the intensive care unit suffer from sleeping problems. There is a need to investigate the effect of sleep-inducing music on sleep disorders in persons with percutaneous transluminal coronary angiography in the cardiac care unit.

DESIGN: An experimental research design was used.

METHODS: Data collection was conducted in the cardiac care unit of K University Hospital in D city, from 3 September-4 October 2010. Fifty-eight subjects participated and were randomly assigned to the experimental group (earplug-delivered sleep-inducing music for 52 min beginning at 10:00 pm, while wearing an eyeshield, n = 29) and the control group (no music, but earplugs and eyeshield worn, n = 29). The quantity and quality of sleep were measured using questionnaires at 7 am the next morning for each group.

RESULTS: Participants in the experimental group reported that the sleeping quantity and quality were significantly higher than control group (t = 3·181, p = 0·002, t = 5·269, p < 0·001, respectively).

CONCLUSION: Sleep-inducing music significantly improved sleep in patients with percutaneous transluminal coronary angiography at a cardiac care unit. Offering earplugs and playing sleep-inducing music may be a meaningful and easily enacted nursing intervention to improve sleep for intensive care unit patients.

RELEVANCE TO CLINICAL PRACTICE: Nurses working at cardiac care unit can use music to improve sleeping in clients with percutaneous transluminal coronary angiography.
