Procedural sedation has become a widely used practice due to the growing need to manage anxiety, discomfort and pain during various diagnostic and therapeutic procedures. The responsibilities and necessary qualifications of anaesthesiologists and non-anaesthesiologists administering procedural sedation have been a topic of debate for years across various national and international guidelines. This narrative review compares national and international recommendations across six areas: pre-procedural assessment and fasting, monitoring standards, pharmacological management, provider training, and paediatric considerations. These areas were examined within clinical guidelines issued by professional organizations representing anaesthesiologists, emergency physicians, paediatricians, gastroenterologists, radiologists, and dentists. While key safety principles—such as continuous monitoring and preparedness for rescue—are broadly endorsed, there remain discrepancies regarding monitoring requirements, definitions of sedation depth, fasting guidelines, and the role of non-anaesthesiologist providers. Special populations, including paediatric and high-risk patients, often require tailored protocols, the level of specificity varies. By identifying areas of consensus and divergence, this review aims to support the development of harmonized best practice frameworks that prioritize safety while allowing for contextual flexibility.
