Background: Fluid is an essential component of initial resuscitation in sepsis or burns. Meanwhile, the optimal strategy of titrating fluids for both of the two conditions remains uncertain. In this bibliometric analysis, we compared the similarities and differences in fluid resuscitation between sepsis and burns in recent publications. Methods: Literatures related to fluid resuscitation in either sepsis or burns were searched in the Web of Science database Core Collection from January 1, 1992, to December 31, 2022. CiteSpace and VOSviewer was used for bibliometric analysis.Results: A total of 1549 and 468 publications on fluid resuscitation in sepsis and burns were retrieved from 1992 to 2022. Based on the occurrences, 341 and 86 high-frequency keywords were screened out from sepsis and burns publications respectively, which were similarly categorized into 5 clusters [i.e. "mechanisms of hypovolemia" (cluster 1), "titration of fluid" (cluster 2), "outcomes or complications" (cluster 3), "pathophysiological alternations" (cluster 4), and "fluid types and others" (cluster 5)]. The high-frequency keywords of the top 20 were more concentrated in cluster 3 and cluster 2, with "mortality" ranked the top in both sepsis and burns literature. Significantly, 3 keywords in cluster 2 ranked in the top 5, including "goal directed resuscitation" (the 3rd ), fluid responsiveness (the 4th ) and fluid balance (the 5th ) in sepsis literature, while the keywords of "microvascular exchange" (cluster 1) and "abdominal compartment syndrome" (ACS, cluster 3) ranked at the second and the fifth place in burns publications. Keyword burst analysis demonstrated that the keyword with the highest burst strength (BS) was "formula" (BS=5.
