A Bibliometric Analysis of the Trends and Evolution on Inhalation Injury Research

Inhalation injury is a common complication in burn patients and is also a factor that can affect the multiple prognoses of burn patients. Attention to inhalation injury began early globally, but few articles have systematically analyzed its development. We employed bibliometric methods to analyze articles on inhalation injury published in 3 medical databases. A total of 3056 relevant articles on inhalation injury were included in our analysis and divided into 3 distinct periods based on Price's law. Notably, a slowdown in publication growth was observed in period III. The majority of these articles were authored by a small group of individuals, with a significant proportion of them being American scholars. In fact, nearly half of the articles were published by American researchers. Applying Bradford's Law, we identified 4 major output sources in the field, namely Burns, Journal of Burn Care & Research, Journal of Trauma, and Critical Care Medicine. Recent research has focused on the clinical risks and outcomes associated with inhalation injury, while basic research in this area has been relatively neglected over the last decade. In conclusion, the growth of publications on inhalation injuries has largely followed standard scientific growth patterns, with a small number of countries and established research groups contributing the majority of articles. However, the recent slowdown in scientific output is a cause for concern, and the lack of emphasis on basic research and clinical trials in this field raises questions about the foundation for widespread clinical management of inhalation injuries.
