目的:探讨白噪声降噪耳塞联合眼罩对ICU患者睡眠质量的改善作用。方法:选择2019年4—11月在聊城市第二人民医院ICU病房住院的患者136例，依照随机数字表法分为3组，第1组为3M耳塞+眼罩45例，第2组为白噪声降噪耳塞+眼罩46例，第3组为对照组45例。入组后第1天晚上，所有患者仅给予常规护理；第2天和第3天晚上，第1组佩戴3M耳塞和眼罩，第2组佩戴白噪声降噪耳塞和眼罩，第3组仅采用常规护理，不佩戴眼罩和耳塞。第2天和第4天上午评估患者基线期理查兹-坎贝尔睡眠量表（RCSQ），Zung焦虑自评量表（SAS）和Zung抑郁自评量表（SDS）评分。结果:干预后，第1组RCSQ中睡眠深度、睡眠潜伏期、夜间觉醒、重回睡眠、睡眠质量、夜间主观噪声感受和总分评分分别为（55.98 ± 19.65）、（57.66 ± 19.56）、（55.68 ± 16.25）、（58.17 ± 11.32）、（60.54 ± 16.33）、（60.65 ± 12.58）和（57.60 ± 17.21）分，第2组分别为（56.65 ± 18.36）、（61.33 ± 20.33）、（65.35 ± 23.22）、（60.36 ± 19.35）、（63.78 ± 20.36）、（66.56 ± 10.21）和（61.49 ± 17.52）分，第3组分别为（45.96 ± 17.79）、（48.36 ± 13.65）、（48.21 ± 13.49）、（51.36 ± 13.65）、（51.33 ± 16.45）、（43.06 ± 17.15）和（49.04 ± 15.32）分，3组间各维度及其总分比较差异有统计学意义（n F值为4.33~8.35，均n P<0.05）；第1组和第2组各维度及其总分均高于第3组，差异有统计学意义（n t值为2.37~7.96，均n P<0.05）。干预后，第2组SAS评分为（43.32 ± 21.68）分，低于第1组的（57.75 ± 22.68）分和第3组的（60.65 ± 19.88）分，差异有统计学意义（n t=3.09、3.99，均n P<0.05）。n 结论:白噪声降噪耳塞或3M耳塞配合眼罩可有效改善ICU患者的睡眠质量，白噪声降噪耳塞配合眼罩还可以缓解患者的焦虑情绪。“,”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.
