A review and bibliometric analysis of global research on non-pharmacologic management for neonatal and infant procedural pain.

Repeated and prolonged exposure to pain can impair neurodevelopmental, behavioral, and cognitive outcomes in newborns. Effective pain management of newborns is essential, but there is no comprehensive analysis of the status of neonatal pain non-pharmacologic management research. Original publications related to the non-pharmacological management of neonatal pain were obtained from the Web of Science Core Collection (WOSCC) between 1989 and 2024. CiteSpace and VOSviewer were used to extract information about countries/regions, institutions, authors, keywords, and references to identify and analyze the research hotspots and trends in this field. 1331 authors from 51 countries and 548 institutions published studies on the non-pharmacological management of neonatal pain between 1989 and 2024, with the number of publications showing an overall upward trend. Canada emerged as the leading country in terms of publication volume, with the University of Toronto and The Hospital for Sick Children identified as key research institutions. High-frequency keywords included "procedural pain," "management," "sucrose," "analgesia," and "preterm infant," resulting in 11 clusters. Keyword emergence analysis revealed that "neonatal pain," "analgesia," "oral sucrose," and "oral glucose" were research hotpots. Analysis of highly cited papers showed that the most referenced articles were published in the Clinical Journal of Pain. Researchers' interest in neonatal procedural pain has increased significantly over the past 30 years. This article can serve as a theoretical reference for future research on mild to moderate pain in neonates and infants, and it can provide ideas for exploring novel and secure pain management strategies.
