Systematic review and analyze the domestic and foreign research literatures on interventional measures for pathological breast engorgement, and explore the differences between intervention measures for pathological breast engorgement at home and abroad, and provide reference and new ideas for further optimization of breast intervention measures in China.

Scientifically search the domestic and foreign research literatures on pathological breast engorgement intervention measures, import the search data into Citespace and VOS viewer to achieve co-occurrence analysis, and then systematically analyze the literature at the core node in the co-occurrence map.

A total of 384 articles (267 foreign ones; 117 articles in China) were included in this study. The main themes of foreign research hotspots are: female, adult, first child, lymphedema, inflammation, breast basic diseases, breast tumors and time-influencing factors are mainly concerned with the exploration of high-risk influencing factors and early intervention of breast-related tumor diseases. Domestic research hotspots mainly focus on nursing interventions as the main intervention measures and effects evaluation. The content analysis in the core literature shows that foreign studies are mainly based on cohort studies, including the topical application of progesterone, psychological intervention, and breastfeeding time factors. Domestic research is mainly based on experimental research, mainly using massage techniques. Improvement, comparison of different external dressings as the main intervention.

At present, both domestic and foreign research have carried out active exploration and comparative research on the external materials and achieved certain results. The current study of postpartum breast engorgement in China needs to be further explored based on large samples and cohort studies.
