324ADVANCEMENTS IN ANAESTHESIA MONITORING: A FOCUSED ASSESSMENT OF RESEARCH AND PRACTICEInhalational anaesthetics have narrow safety margins, with therapeutic indices ranging between 2 and 4.2. Despite significant reductions in anaesthesia-related mortality over the past four decades, largely due to improved monitoring and administration techniques, there have been few groundbreaking advancements in the safety profiles of these agents. Aim: This study evaluates progress in anaesthesia monitoring using scientometric indices to identify research trends and gaps, with the ultimate goal of enhancing patient safety and reducing complications. Methods: Conducted in 2024 at Jakir Hossain Medical College, West Bengal, and MediCiti Institute of Medical Sciences, Telangana, India, this study involved 150 patients. Monitoring techniques such as pulse oximetry, capnography, and bispectral index monitoring were assessed using scientometric indices: General Popularity Index (GPI), Specific Popularity Index (SPI), Change Index (CI), and Expectations Index (EI). Data from 35 monitoring topics were extracted from PubMed for analysis. Results: Pulse oximetry (GPI = 15%, SPI = 18.2), capnography (GPI = 12%, SPI = 14.7), and bispectral index monitoring (GPI = 10%, SPI = 12.0) emerged as the most frequently studied topics, reflecting their critical role in improving anaesthesia safety. Techniques such as central venous pressure monitoring (CI = 62) and cerebral oximetry (CI = 55) showed significant growth, while entropy monitoring and kinemyography remained underexplored. Complications, including cardiac arrest (3.3%) and respiratory insufficiency (6.7%), were minimal, underscoring the effectiveness of established techniques. Conclusion: Advanced anaesthesia monitoring techniques have significantly improved safety and reduced complications. However, less-studied modalities present opportunities for innovation. A balanced research approach addressing both established and emerging techniques is essential for advancing the field and improving patient outcomesdrnagarajukims@gmail.comResearch1422024Anaesthesia Monitoring, Pulse Oximetry, Scientometric Analysis, Patient Safety, CapnographyAdduri Nagaraju,Kalyan N,Yeeda SrishaAssistant Professor, Department of Anaesthesiology, Jakir Hossain Medical college and research institute, Prasadpur, P.O.
