摘要

背景:昼夜节律紊乱可对人体生理和保健结果产生重大影响，已证实ICU发病率、死亡率和住院时间增加。方法:我们进行了一项多中心观察性研究，研究了3个重症监护病房患者的夜间lux暴露。结果:6小时记录的中位光强为1勒克斯;然而，这是欺骗性的，因为它隐藏了短时间的高勒克斯。当在较短的30分钟的时间段内观察时，勒克斯值明显高于粗中值，特别是在高敏度患者中。通过SOFA评分估计的锐度与最大勒克斯(R = 0.479, p = 0.0001)、中位勒克斯(R = 0.35, p = 0.006)和累积勒克斯(R = 0.55, p = 0.000001)呈正相关。邻近患者的视敏度与勒克斯之间没有关系。结论:临床医生应在夜间提高警惕，为患者提供最佳的环境条件，以尽量减少潜在的危害。

A prospective multicentre observational study to quantify nocturnal light exposure in intensive care.

Background: Disrupted circadian rhythms can have a major effect on human physiology and healthcare outcomes, with proven increases in ICU morbidity, mortality and length of stay.

Methods: We performed a multicentre observational study to study the nocturnal lux exposure of patients in 3 intensive care units.

Results: The median light intensity recorded was 1 lux over the 6-hour recording period; however, this is deceptive as it hides short periods of high lux. When looked at in shorter time segments of 30 minutes, there were significant periods of lux higher than a crude median, especially in higher acuity patients. There was a positive correlation between acuity (as estimated by SOFA score) and maximum lux (R = 0.479, p = .0001), median lux (R = 0.35, p = .006) and cumulative lux (R = 0.55, p = .000001). There was no relationship between neighbouring patient acuity and lux.

Conclusions: Clinicians should practice vigilance at night to provide optimal environmental conditions for patients to minimise potential harm.

期刊介绍： The Journal of the Intensive Care Society (JICS) is an international, peer-reviewed journal that strives to disseminate clinically and scientifically relevant peer-reviewed research, evaluation, experience and opinion to all staff working in the field of intensive care medicine. Our aim is to inform clinicians on the provision of best practice and provide direction for innovative scientific research in what is one of the broadest and most multi-disciplinary healthcare specialties. While original articles and systematic reviews lie at the heart of the Journal, we also value and recognise the need for opinion articles, case reports and correspondence to guide clinically and scientifically important areas in which conclusive evidence is lacking. The style of the Journal is based on its founding mission statement to ‘instruct, inform and entertain by encompassing the best aspects of both tabloid and broadsheet''.
