Sleep is a basic physiological need and is imperative for healing and rejuvenation. However, the environment of the intensive care unit (ICU), including loud sounds and bright lights, can undermine patients' sleep quality.
This study was designed to determine the effectiveness of overnight use of earplugs and eye masks to improve sleep quality and potentially influence hemodynamic parameters and mitigate fatigue among nonventilated patients in an ICU.
This experimental study was conducted among 84 nonventilated patients in an ICU. The patients were evenly divided between an intervention group (n=42) and a control group (n=42). The intervention group patients received earplugs and eye masks for three consecutive nights from 10:30 pm to 6:30 am, while the control group patients received routine care. Clinical data, responses to the Richards-Campbell sleep questionnaire, and rankings on a numerical fatigue scale were collected before (pretest) and after the intervention each night and the next morning (posttests 1, 2, and 3).
The results revealed a significant reduction in fatigue. At pretest, fatigue scores in the study group were 4.19±1.64. The score was significantly reduced to 3.40±1.39 at posttest 1 and then to 2.21±1.00 at posttest 3 (p<0.0001). The sleep quality for the study group showed a significant improvement from the pretest score of 43.73±8.27 to 60.35±6.85 at posttest 3 (p<0.001), whereas the control group had slightly worse sleep quality, with 40.64±8.67 at pretest and 45.63±6.95 at posttest 3.
Continuous patient monitoring is an essential nursing care activity in ICUs while ensuring good-quality sleep promotes healing and reduces fatigue. Sleep quality can be supported by devices such as earplugs and eye masks to limit undue disturbances in the ICU settings.
睡眠是一项基本的生理需求，对康复和恢复活力至关重要。然而，重症监护病房（ICU）的环境，包括噪音和强光，会破坏患者的睡眠质量。
本研究旨在确定夜间使用耳塞和眼罩对改善ICU中未通气患者的睡眠质量、潜在影响血流动力学参数以及减轻疲劳的有效性。
本实验研究在一所ICU的84名未通气患者中进行。患者被平均分为干预组（n = 42）和对照组（n = 42）。干预组患者连续三个晚上从晚上10:30至次日早上6:30佩戴耳塞和眼罩，而对照组患者接受常规护理。在干预前（预测试）以及干预后每晚和次日早晨（后测试1、2和3）收集临床数据、对理查兹 - 坎贝尔睡眠问卷的回答以及数字疲劳量表的排名。
结果显示疲劳显著减轻。预测试时，研究组的疲劳评分为4.19±1.64。在后测试1时，该评分显著降至3.40±1.39，然后在后测试3时降至2.21±1.00（p<0.0001）。研究组的睡眠质量从预测试时的43.73±8.27显著改善至后测试3时的60.35±6.85（p<0.001），而对照组的睡眠质量略差一些，预测试时为40.64±8.67，后测试3时为45.63±6.95。
持续的患者监测是ICU中一项必不可少的护理活动，同时确保高质量睡眠可促进康复并减轻疲劳。耳塞和眼罩等设备有助于支撑睡眠质量，减少ICU环境中的不当干扰。
