Background: Pediatric bronchoscopy has been used widely applied in the diagnosis and treatment of pulmonary related diseases during recent two decades. This study aimed to explore the current status and hotspots of pediatric bronchoscopy by bibliometric analysis.

Methods: The Web of Science core collection database was retrieved for articles on pediatric bronchoscopy. The screened period ranged from the creation of the database to April 28, 2022. The original articles written in English were selected to obtain data. Microsoft Excel, Endnote and VOSviewer were used to analyze the data.

Results: There were 675 original articles with a total citation frequency of 14169. The first related article was published in 2003, then the number of published articles was increasing gradually and reached 78 in 2021. The United States of America (USA) and China were the top two countries with the most articles. They contributed 42.51% articles. The top one institution with the most articles was University of Pennsylvania. Pediatric Pulmonology published the most articles (110 articles). The most productive authors contributed 14 articles respectively, and they were Cakir Erkan, from Bezmialem Vakif University in Trukey and Goussard Pierre, from Stellenbosch University in South Africa. By cluster analysis, the keywords were divided into six clusters: trachea malformations, pneumonic and asthma diseases, trachea-esophageal malformations, foreign body, sedation, and risk assessment. The sedation cluster appearance time was the latest one (2014.08±0.57). The most occurrence keywords were management (128), bodies (177), diagnosis (93), complication (82), and bronchoalveolar lavage (75).

Conclusion: Pediatric bronchoscopy draw attention of the worldwide pediatricians, and the number of related articles gradually increased. The USA and China played the leading roles in the research. The hotspots focused on the trachea and esophageal malformation, pneumonic and asthma diseases, foreign body, sedation, and risk assessment.
