disorders are a common problem in patients in the critical care unit. The
objective of the present study was to determine the effect of white noise on
the quality of sleep in patients admitted to the CCU.
present study was single-blind, quasi-experimental study. A total of 60
patients were selected using the purposive sampling method. Quality of sleep
was measured with PSQI on the first day in admission, then after three nights
of admission without any intervention for control group and for the
experimental group quality of sleep measured by white noise with intensity of
50-60 dB then Quality of sleep was measured with PSQI. Data were analyzed by
SPSS 13 software.
average total sleep time in the control group before the study reached from
7.08 (0.8) to 4.75 (0.66) hours after three nights of hospitalization, while in
the experimental group, no significant changes were seen in the average sleep
hours (6.69 ± 0.84 vs. 6.92 ± 0.89, P = 0.15).The average minutes of sleep in
the control group before the study reached from 12.66 (7.51) to 25.83 (11.75)
minutes after a three- night stay, while in the experimental group, no
significant changes were observed in the average sleep duration (12.16 ± 7.50
vs. 11 ±6. 07, P = 0.16).
Conclusion: The use of white noise is recommended as a
method for masking environmental noises, improving sleep, and maintaining sleep
in the coronary care unit.
