The effect of music on sleep in efficiency among patients during admission in the coronary care unit
Abstract:
This quasi-experimental research, cross over design aimed to determine the effect of music on sleep efficiency among the patients during admission in the coronary care unit (CCU). Thirty patients who were admitted in the CCU at the King Chulalongkorn Memorial Hospital were selected by purposive sampling during October to December 2004.
A compact disk of relaxing music with non-lyric-containing, slow, and steady rhythms that duplicated pulses of 60 to 80 beats per minute was used as music intervention. Seven CDs composed of two classical music, three natural music, and two Thai modern music were available for the patient to select. Sleep efficiency was measured by the portable polysomnography (PSG) in terms of sleep efficiency index (SEI), time spent in each sleep stage compare to the total sleep time (TST), sleep latency (SL), and TST. PSG was monitored throughout the two study nights, for each participant, without music and with 30 minutes music played before going to sleep. The sequence of the two periods was randomly assigned by a coin flip for each participant. Equal of them started with or without music for the first study night. The results of the study showed that SEI in the night with music was higher than the night without music, but not statistically significant. The mean time spent in stage 2 NREM sleep in the night with music was statistically significant and shorter than the night without music (p<.05). TST in the night with music was statistically significant and longer than the night without music (p<.05). The mean time spent in stage 3, 4 NREM sleep and REM sleep in the night with music were not statistically significant and less than the night without music. The mean time spent in stage 1 NREM sleep and SL in the night with music were longer than, but not statistically significantly different (p>.05). In conclusion, this study showed that the patients during admission in the CCU had poor sleep efficiency. Music can promote sleep efficiency in some ways and it is suggested that it be used in clinical practice."
