摘要/Abstract

摘要：

目的采用Meta分析的方法系统评价白噪声对ICU患者睡眠质量的影响。方法通过计算机检索CINAHL、PubMed等11个数据库中关于白噪声对急危重症患者睡眠质量影响的文献，检索时间为建库至2024年3月11日。由2名研究者独立进行文献筛选、资料提取和偏倚风险评估后，采用RevMan 5.4软件对纳入文献进行Meta分析。结果最终9篇文献、792例研究对象被纳入研究，Meta分析结果显示，白噪声可以改善ICU患者睡眠[MD=-4.63，95%CI（-7.11，-2.14），P<0.001]，加快入睡速度[MD=21.82，95%CI（8.14，35.50），P<0.001]，提高睡眠深度[MD=19.18，95%CI（7.05，31.31），P<0.001]，减少夜间觉醒次数[MD=20.36，95%CI（6.46，34.26），P<0.001]，加快再入睡[MD=23.72，95%CI（9.22，38.22），P<0.001]，提高睡眠质量[MD=21.66，95%CI（8.07，35.25），P<0.001]，降低噪声水平[MD=29.27，95%CI（10.74， 47.79），P<0.001]，可以延长患者睡眠时长，能减轻患者焦虑[MD=-8.11，95%CI（-10.55，-5.68），P<0.001]和抑郁[MD= -5.86，95%CI（-8.76，-2.96），P<0.001]。结论白噪声可以明显改善ICU患者睡眠状况和减轻患者焦虑、抑郁等负面情绪，但纳入研究的文献质量较低，研究间异质性较高，需大样本、设计严谨、高质量的随机对照试验进一步证实。

Abstract:

Objective To systematically evaluate the effect of white noise on sleep quality of ICU patients by meta-analysis. Methods The studies on the effects of white noise on sleep quality in critically ill patients were searched by computer from 11 databases，including CINAHL and PubMed. The search limit was from the inception of the database to March 11，2024. Two researchers independently screened literature，extracted data and assessed the risk of bias. RevMan 5.4 software was used for meta-analysis. Results A total of 9 studies involving 792 subjects were included in the study. The results of meta-analysis showed that white noise could improve sleep in ICU patients[MD=-4.63，95%CI（-7.11，-2.14），P<0.001]，accelerate the speed of falling asleep[MD=21.82，95%CI（8.14，35.50），P<0.001]，and improve sleep depth[MD=19.18，95%CI（7.05，31.31），P<0.001]，reduce the number of nocturnal awakenings[MD=20.36，95%CI（6.46，34.26），P<0.001]，accelerate re-falling asleep[MD=23.72，95%CI（9.22， 38.22），P<0.001]，improve sleep quality[MD=21.66，95%CI（8.07，35.25），P<0.001]，reduced noise level[MD=29.27， 95%CI（10.74，47.79），P<0.001]. White noise could prolong patients’ sleep duration，and reduce patients’ anxiety[MD=-8.11，95%CI（-10.55，-5.68），P<0.001] and depression[MD=-5.86，95%CI（-8.76，-2.96），P<0.001]. Conclusion White noise can significantly improve the sleep status of ICU patients and reduce negative emotions such as anxiety and depression，but the quality of the included studies is low，and the heterogeneity between studies is high，which needs to be further confirmed by large-sample，well-designed and high-quality randomized controlled trials.
