Regional anaesthesia has emerged as a cornerstone in modern surgical practices, offering targeted pain relief, reduced systemic drug exposure, and faster recovery times. Recent technological advancements have revolutionised its application, improving precision, safety, and patient outcomes. This study explores the role of innovations such as ultrasound guidance, artificial intelligence (AI), and long-acting anaesthetics in enhancing the efficacy of regional anaesthesia. Ultrasound technology has enabled real-time visualisation of nerve structures, reducing complications and increasing block success rates. AI-powered systems hold promise for predicting optimal anaesthetic approaches and guiding practitioners during procedures. Similarly, long-acting anaesthetics and advanced catheter techniques have extended pain relief duration and minimised opioid dependency. However, these advancements face challenges, including training requirements, high equipment costs, and variability in adoption across healthcare settings. This paper reviews 15 recent studies on these innovations, providing a comprehensive analysis of their impact on surgical outcomes. Through an evaluation of clinical trials, case studies, and meta-analyses, the research highlights both the transformative potential and the barriers to widespread implementation. The findings emphasise the need for increased investment in training, infrastructure, and research to realise the full benefits of these technologies. This study concludes that integrating technological advancements into regional anaesthesia protocols can significantly enhance patient care and operational efficiency, paving the way for its broader adoption in complex surgical environments.
