The knowledge structure, research hotspots and trends related to postoperative pain in children are unclear and have not been systematically summarized.Purpose: We aimed to analyze the current state of research on postoperative pain in children and to conduct in-depth mining of the knowledge structure.Methods: The PubMed database for publications on postoperative pain in children between 1950 and 2021 was searched. Bibliographic Item Co-Occurrence Matrix Builder (BICOMB) was performed to obtain the co-word matrix and co-occurrence matrix. The H-index method was used to extract high-frequency main Medical Subject Headings (MeSH) terms/subheadings.Results: The high-frequency MeSH terms were analyzed by biclustering, strategic diagram and social network analyses. Totally, 4022 publications were retrieved. The analysis showed that 60 countries or regions published relevant documents, with the United States publishing the most significant number of papers. Totally, 811 journals published relevant papers, with Pediatric Anesthesia ranking first. Moreover, we extracted 43 high-frequency main MeSH terms/subheadings and clustered them into five categories: overview, aetiology and epidemiology, pharmacotherapy, opioid administration and dosing, and prevention and control of postoperative pain in children.Conclusion: Pharmacological treatments, pain prevention and control are the focus of research and are becoming increasingly mature. Opioid stewardship and regional anesthesia is the trend and focus of future research. Our study offers a better understanding of the current status and knowledge structure of postoperative pain in children and provides a reference for improving postoperative pain management in children in the future.Keywords: bibliometrics, visualization analysis, postoperative pain, children, status, trends
