Non-operating Room Anesthesia (NORA): A Comprehensive Review of Monitored Anesthesia Care

Monitored anesthesia care (MAC) is being increasingly employed in non-operative environments, particularly in the realms of endoscopy and magnetic resonance imaging (MRI) procedures. This in-depth analysis delves into the essential components of MAC within these specific contexts, with a primary focus on ensuring patient safety, evaluating efficacy, and assessing procedural outcomes. It is a common practice in endoscopic procedures to necessitate sedation for the purpose of alleviating discomfort and anxiety, ultimately ensuring patient cooperation and the successful completion of the procedure. MAC, which entails the administration of sedatives and analgesics under the close supervision of an anesthesia professional, offers a personalized approach that carefully balances the depth of sedation with maintaining optimal patient safety standards. Within the domain of MRI procedures, where challenges such as claustrophobia and motion artifacts can significantly impact the process, MAC plays a crucial role in providing a controlled setting that not only enhances image quality but also improves patient compliance throughout the procedure. The review extensively investigates the various pharmacological agents commonly utilized in these scenarios, including but not limited to midazolam and fentanyl, shedding light on their pharmacokinetic and pharmacodynamic properties specific to these contexts. Furthermore, the critical role of the anesthesia provider in effectively managing potential complications, such as respiratory depression, hemodynamic instability, and allergic reactions, is thoroughly examined and discussed. The analysis extends to the implementation of MAC protocols, encompassing pre-procedural assessments, continuous intra-procedural monitoring, and comprehensive post-procedural care, all aimed at ensuring the best possible outcomes for patients. Additionally, the review delves into the economic considerations associated with MAC, taking into account its impact on procedural efficiency, healthcare costs, and patient throughput within these settings. By exploring current guidelines and recommendations established by professional societies such as the American Society of Anesthesiologists (ASA), this review aims to provide a holistic understanding of the best practices in MAC for both endoscopy and MRI procedures. Through the synthesis of available evidence, the primary objective of this review is to contribute to informing clinical practices, enhancing patient safety measures, improving procedural success rates, and ultimately advocating for the broader adoption of monitored anesthesia care in diverse non-operative medical settings.
