Bibliometric and visualized analysis of peripartum respiratory complications from 2004 to 2023

Background: Peripartum respiratory complications are a major reason for pregnant women's admission to the ICU, even endangers the maternal life. This bibliometric analysis was designed to elucidate the spectrum of diseases and risk factors for various respiratory complications during the peripartum period, as well as the future research directions in this field.

Methods: Relevant publications were downloaded from the Web of Science Core Collection on November 1, 2023. CiteSpace was utilized for conducting the scientometric study.

Results: A total of 2,331 articles and reviews on respiratory complications during pregnancy published between 2004 and 2023 were retrieved, comprising 87,244 co-cited references, originating from 568 institutions across 104 countries/regions. The United States emerged as the leading country in this domain, with Harvard University standing out as the most actively engaged institution. Bibliometric analysis reveals that the current research hotspots include "COVID-19 pandemic," "venous thromboembolism," "respiratory distress syndrome" and "cardiovascular diseases." Meanwhile, "venous thromboembolism," cytokine storm" and supportive management such as "extracorporeal membrane oxygenation" might represent potential future research directions.

Conclusion: Over the past two decades, research on respiratory system complications in pregnancy has continually evolved. This study contributes to enabling researchers in the related field to understand future research hotspots and trends, providing information on potential collaborators, institutions, countries, and citation references.
