Electroencephalography-based evaluation of the impact of night-time nursing care on sleep during intensive care unit administration after cardiac surgery.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
After highly invasive cardiac surgery, critically ill patients require night-time nursing care for life support. Even in patients administered dexmedetomidine for sedation, nursing care potentially disrupts sleep and affects circadian rhythms. However, the impact of night-time nursing care on sleep in intensive care unit (ICU) patients have not been objectively evaluated, and the effects of sedatives have not been objectively confirmed. The current study investigated how night-time nursing care affected sleep in patients who had undergone cardiac surgery, by analyzing dynamic changes in electroencephalogram (EEG) data. Two groups were investigated: a dexmedetomidine group and a non-dexmedetomidine group. The decision whether to administer dexmedetomidine was based on clinical judgment. EEG data were extracted for 30 s intervals before and after performing care for 150 s. Power spectrum density (PSD) was analysed using a linear mixed-effects model. In both groups, PSD (alpha and beta bands) was significantly higher after care than before care. Intermittent sleep occurred during nursing care even in patients under dexmedetomidine sedation. Thus, regardless of whether sedatives are used nighttime nursing care causes sleep interruptions, and centralizing nursing and routine care is crucial to ensure good sleep.
