Abstract:
Objective:This study examined the development trend and research hotspot of cardiopulmonary brain resuscitation in the last ten years by a visual analysis of the literature on post-cardiac arrest brain injury.Methods:English articles were acquired from the Web of Sciences (WOS) core database. CiteSpace 5.8.R3 software was used to analyze annual publications, countries, institutions, authors. We identified the trending research areas by analyzing collaborative networks, keywords co-occurrence, burst detection analysis, timeline and time-zone diagrams.Results:The search included 10 867 articles in the WOS core database from Jan 1, 2013 to Oct 25, 2023. In the last ten years, the top 3 nations were the United States, China, and Japan, with the United States having the most citation of 3691 and an centrality of 0.47. The author with the highest number of publications was Hans Friberg from Sweden. The top 5 most frequent keywords in WOS were cardiac arrest, cardiopulmonary resuscitation, resuscitation, survival, outcome. Keyword cluster analysis showed 4 clusters, including: #0 of-hospital cardiac arrest, #1 traumatic brain injury, #2 targeted temperature management, #3 global cerebral ischemia. Keyword burst showed that the top 5 ranked by strength are mild hypothermia, emergency cardiovascular care, neuron specific enolase, cerebral ischemia, epinephrine, and the top 5 ranked by the year of burst begins are out-of-hospital cardiac arrest, cpr, epinephrine, coma, and task force. The timeline and time zone charts indicated that, starting in 2017, the main fields of study concentration were traumatic brain injury and out-of-hospital cardiac arrest. Additionally, extracorporeal membrane, intensive care, risk factors, and electroencephalography were identified as new high-frequency keywords.Conclusions:Over the past ten years, the research hotspots on post-cardiac arrest brain injury include out-of-hospital cardiac arrest, traumatic brain injury, and target temperature control. The research development trends will be extracorporeal membrane oxygenation, critical care, and EEG.
