Non-fungible token (NFT) is a relatively new and developing trend in digital finance research that is fundamentally transforming the process of trading digital assets. The objective of this study is to present a concise overview and analysis of current research trends regarding NFT, with the intention of providing researchers with a framework for guiding future investigations in this field. In order to give researchers a framework for directing future studies in this area, the study objective is to provide a succinct review and analysis of current research trends. The objective of the study is to present a concise overview and analysis of current NFT research trends. We started by arranging framework of bibliometric study, setting appropriate keywords and operating the software. In the process, this study thoroughly examined 99 academic publications about NFTs that were listed in the Scopus database between 2009 and 2024 using VOSviewer. Our research shows that the analysis identifies four separate research clusters with a focus on digital economy, security, connections with other blockchains, and intellectual property. We conclude by making recommendations for the future based on the trends and gaps found in this bibliometric review.
ABSTRACT Introduction The effectiveness of stellate ganglion block in managing acute postoperative pain remains uncertain due to limited high‐quality evidence. This study evaluates the impact of stellate ganglion block on acute pain following arteriovenous fistula surgery. Methods A randomized controlled clinical trial was conducted in the Surgery Department of Bahonar and Shafa Hospitals at Kerman University of Medical Sciences, Iran. Patients undergoing arteriovenous fistula surgery were randomly assigned to either the intervention group, which received an ultrasound‐guided stellate ganglion block with 5 mL of 5% lidocaine, or the control group, which received no intervention. A total of 60 patients were selected based on age and gender similarity. Pain levels were assessed using the visual analog scale immediately after surgery and at 6 and 12 h postoperatively. Findings Pain scores differed significantly between the two groups at all time points ( p ≤ 0.05). The intervention group reported lower pain levels at 6 and 12 h postoperatively compared to the control group. Repeated measures analysis confirmed a significant reduction in pain over time in both groups ( p ≤ 0.05), with a more pronounced decrease in the intervention group ( p ≤ 0.05). Conclusion Preoperative stellate ganglion block effectively reduces acute postoperative pain following arteriovenous fistula surgery. However, its effects beyond the 12‐h postoperative period remain unknown. Further research is needed to evaluate its long‐term impact.
