Bibliometric and knowledge map analysis of one lung ventilation

Background: One lung ventilation (OLV) is an essential method of lung isolation to protect the ventilated lung from soiling by the contralateral lung and obtain optimal surgical exposure in thoracic surgery. This study aims at using bibliometrics to analyze the research status of OLV, to summarize the academic frontier and hotspots, and provide directions for future research comprehensively and objectively. Methods: The papers and reviews related to OLV were retrieved by the topic search from Web of Science Core Collection (WoSCC). The bibliometric analysis was performed on Excel 365, CiteSpace, VOSviewer and reference meters (tool R of R-Studio). Results: A total of 1,552 articles and reviews on OLV research were identified, which showed an overall growing trend from 1982 to 2022. The United States was the leader in this field, accounting for the largest number of publications (299), followed by China (261) and Japan (158). Among all institutions, Yonsei University had the largest number of publications (23), but National Taiwan University Hospital had the highest number of cited publications (876). The papers related to OLV were mainly published in Journal of Cardiothoracic and Vascular Anesthesia (147) and Anesthesiology (4,380) was the most frequently cited journal. The most productive author was Cheng YJ (15), but Benumof JL had the highest number of co-citations (468). After keywords analysis, the most common keywords are “one-lung ventilation” (575), “thoracic surgery” (154), and “double-lumen tube” (96). “Infants”, “dexmedetomidine”, “inflammation”, and “airway management” are newly emergent research hotspots. Conclusion: Through bibliometric and visualization methods, we undertook a comprehensive analysis in the field of OLV. The United States maintained a top position in this field, the emerging hotspots of OLV has changed from basic research to clinical research and the further innovation of OLV management. This study will provide new ideas for scholars in their future works.
