Intranasal dexmedetomidine for perioperative sleep disturbance: a protocol for a systematic review with meta-analysis and trial sequential analysis.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionPerioperative sleep disturbance (PSD) can adversely affect immunological and cognitive functions, can prolong hospital stays and have long-lasting effects on quality of life, ultimately increasing mortality rates. Unfortunately, PSD is common among surgical patients and can manifest at any stage during surgical care with a high incidence. Owing to the high incidence and severe adverse outcomes of PSD, effective management of PSD is imperative in clinical practice. Intranasal administration of dexmedetomidine is a safe and effective strategy for improving perioperative sleep quality. It is characterised by high bioavailability, a low incidence of adverse events and the avoidance of pain from venipuncture and intramuscular injection. However, this clinical evidence is insufficient due to the limited sample size, diverse outcome observation indicators and inconsistent research quality. Consequently, we will conduct a protocol for a systematic review and meta-analysis to offer clinical evidence on whether intranasal dexmedetomidine can be opted as an effective treatment for PSD. METHODS AND ANALYSIS: English databases (PubMed, Web of Science, Ovid Medline, Embase and Cochrane Library), Chinese electronic databases (Wanfang database, VIP Database and China National Knowledge Infrastructure) and clinical trial registry platforms will be screened from their inception up to October 2025 to detect randomised controlled trials of intranasal dexmedetomidine for the management of PSD. We will compute the mean differences (MDs) or standardised MDs along with 95% CIs for continuous data, and the risk ratio with 95% CIs for dichotomous data using Review Manager V.5.4. Either the fixed-effects or random-effects model will be employed depending on the heterogeneity assessed by Cochran's Q test and the I ETHICS AND DISSEMINATION: Ethical approval was not required for this systematic review protocol. The results will be disseminated through peer-reviewed publications. PROSPERO REGISTRATION NUMBER: CRD420251002119.
