The use of bispectral index for monitorization of the depth of sedation in procedural sedoanalgesia in the emergency department. Annals of Clinical and Analytical Medicine, 17, pp. 119-123. https://doi.org/10.4328/ACAM.226822667-663Xhttps://doi.org/10.4328/ACAM.22682https://hdl.handle.net/20.500.13055/1418Aim: To determine the effectiveness of the Bispectral Index (BIS) measurement as an objective criterion for measuring the depth of sedation in the emergency department (ED) by comparing it with the Modified Ramsey Sedation Scale (MRSS), which is a clinical scale for measuring sedation depth. Methods: In this study, the compatibility of BIS values and MRSS values at the moment when the patients reached clinically appropriate sedation depth for intervention in those requiring sedation-analgesia in the ED due to extremity trauma were compared. Results: No statistically significant correlation was found between patients’ initial MRSS scores at the time of intervention and either their initial or minimum BIS values (p>0.05). A moderate negative correlation (r=-0.432, p=0.022) was observed between the MRSS values and the minimum BIS readings. No statistically significant difference was observed in minimum BIS values based on the sedative agent administered (p>0.05). Conclusion: In this study, a moderate correlation was found between the lowest BIS values and the MRSS scores corresponding to those BIS values. Although further comprehensive and detailed studies are necessary to establish the limitations and optimal use of BIS monitoring during procedural sedation-analgesia in the ED—especially considering both existing literature and the limitations of this study—BIS appears to be a promising alternative to clinical sedation scales for monitoring sedation depth.eninfo:eu-repo/semantics/openAccessSedationModified Ramsey Sedation ScaleBispectral IndexEmergency DepartmentSedation Depth MeasurementArticle10.4328/ACAM.2268217119123Q4WOS:001721396700005
