Perioperative pulmonary infection prevention and management in adult patients after coronary artery bypass grafting: a summary of best evidence.
Synthesis in BMC cardiovascular disorders, 2026. 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
backgroundCoronary artery bypass grafting is an important surgical treatment for coronary heart disease. As an open thoracic procedure, pulmonary infection is a common and potentially serious complication of coronary artery bypass grafting. Its occurrence may prolong mechanical ventilation, increase hospital length of stay, and raise mortality risk. This study therefore aims to evaluate and summarise the evidence for the prevention and management of perioperative pulmonary infection in patients undergoing coronary artery bypass grafting to inform clinical practice.
methodsThis evidence summary adheres to the standardised reporting framework of the Fudan University Centre for Evidence-Based Nursing (Registration No: ES20246831). The process encompassed clinical question identification, evidence retrieval, literature screening, methodological quality assessment, and evidence synthesis and grading. A systematic search was conducted from January 1, 2015, to December 31, 2025, across the following databases: UpToDate; BMJ Best Practice; the UK National Institute for Health and Care Excellence; the Registered Nurses’ Association of Ontario; the National Guideline Clearinghouse; the Scottish Intercollegiate Guidelines Network; the Guidelines International Network; the Cochrane Library; the JBI Evidence Synthesis Database; PubMed; Web of Science; the China National Knowledge Infrastructure; Wanfang Data; and the Medlive Guidelines Network. Literature types included clinical decisions, guidelines, expert consensuses, systematic reviews, and evidence summaries.
resultsThis study included 19 publications comprising 2 clinical decisions, 2 guidelines, 2 expert consensuses, 6 systematic reviews, and 7 evidence summaries. It synthesised 4 themes and 23 best practice recommendations covering four critical phases: risk assessment and optimisation; preoperative early exercise and prehabilitation; intraoperative safety strategies and anaesthetic management; and postoperative respiratory exercise and rehabilitation.
conclusionThis study systematically synthesised 23 evidence-based measures for preventing and managing pulmonary infection in coronary artery bypass grafting patients. Collectively, these measures form a systematic approach to pulmonary infection prevention and management. Implementation of these recommendations may enable healthcare providers globally to enhance the quality and standardization of perioperative coronary artery bypass grafting care, while reducing the incidence of perioperative pulmonary infections and associated prognostic burden.
