Effect of white noise reduction earplugs combined with eye mask on sleep quality of ICU patients / 中国实用护理杂志

ABSTRACT

Objective:To investigate the effect of white noise reduction earplugs combined with eye mask on the sleep quality of ICU patients.Methods:A total of 136 patients who were hospitalized in the ICU ward of the Second People′s Hospital of Liaocheng from April to November 2019 were selected and divided into 3 groups according to the random number table method. Group 1 (3M earplug + eye mask, 45 cases), group 2 (white noise reduction earplug + eye mask, 46 cases), and group 3 (control group, 45 cases). On the first night after enrollment, all patients were given routine care only. On the second and third nights, group 1 was given 3M ear plugs and eye masks, group 2 was given white noise reduction earplugs and eye masks, and group 3 was given routine care only. On the morning of the second and fourth day, patients′ baseline Richards Campbell Sleep Questionnaire (RCSQ), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) scores were assessed.Results:After the intervention, the sleep depth, sleep latency, wake at night, return to sleep, sleep quality, nocturnal subjective noise perception and total score in RCSQ in group 1 were (55.98 ± 19.65), (57.66 ± 19.56), (55.68 ± 16.25), (58.17 ± 11.32), (60.54 ± 16.33), (60.65 ± 12.58), (57.60 ± 17.21) respectively, in group 2 were (56.65 ± 18.36),(61.33 ± 20.33), (65.35 ± 23.22), (60.36 ± 19.35), (63.78 ± 20.36), (66.56 ± 10.21) and (61.49 ± 17.52), in group 3 were (45.96 ± 17.79), (48.36 ± 13.65), (48.21 ± 13.49), (51.36 ± 13.65), (51.33 ± 16.45), (43.06 ± 17.15) and (49.04 ± 15.32). There were statistically significant differences in each dimension and its total scores among the three groups (F values were 4.33-8.35, all P<0.05). Compared with group 3, each dimension and total scores of groups 1 and group 2 were higher than those of group 3, and the differences were statistically significant (t values were 2.37-7.96, all P<0.05). After the intervention, the SAS score of group 2 was (43.32 ± 21.68), which was lower than that of group 1 (57.75 ± 22.68) and group 3 (60.65 ± 19.88), and the difference were statistically significant (t=3.09, 3.99, both P<0.05).Conclusions:3M earplugs or white noise reduction earplugs combined with eye masks can effectively improve the sleep quality of ICU patients, and white noise reduction earplugs combined with eye masks can also relieve the anxiety of patients.
