Preoperative Anxiety and Postoperative Delirium: A Mini Review of the Association, Mechanisms, and Preventive Strategies.
Review in Journal of multidisciplinary healthcare, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Preoperative anxiety, a common perioperative psychological state characterized by restlessness and somatic symptoms, has been reported to affect a broad range of adult surgical patients, with prevalence estimates ranging from approximately 11% to 80% across observational studies, and affects a similar proportion of pediatric patients, with one cross‑sectional study reporting an incidence of around 67.6% in Chinese children undergoing elective surgery. Mounting evidence suggests that preoperative anxiety may be a potential contributing factor to postoperative delirium (POD), an acute cognitive disturbance associated with poor prognosis, increased mortality, and elevated healthcare costs. This mini-review synthesizes the role of preoperative anxiety in predicting POD, highlighting its significance in identifying high-risk populations. This mini-review aims to synthesize current evidence on the impact of preoperative anxiety on POD, clarify underlying pathophysiological mechanisms, and summarize recent pharmacological and non-pharmacological preventive strategies. Mechanistically, preoperative anxiety contributes to POD via systemic and neuroinflammatory responses, blood-brain barrier disruption, postoperative pain amplification, and oxidative stress. Pharmacological interventions (eg, dexmedetomidine, ketamine in pediatric patients) and non-pharmacological strategies (eg, music therapy, virtual reality-based cognitive-behavioral interventions) effectively alleviate preoperative anxiety and reduce POD incidence. Despite progress, the mechanisms linking preoperative anxiety to POD remain incompletely understood, particularly the roles of neuroinflammatory pathways, blood-brain barrier disruption, and the comparative effectiveness of pharmacological versus non-pharmacological interventions. Targeted research in these areas is needed to optimize preventive strategies and improve surgical outcomes.
