Standards of care for procedural sedation: Focus on differing perceptions among societies

Adherence to established standards of care is important for anaesthesiologists to avoid undesirable legal consequences of their actions. The judiciary lays stress on the need to perpetuate healthy doctor-patient correspondence, good documentation, and to bestow a justifiable standard of care. But what defines standard of care and who delineates such standards is something that lacks clarity. The American Society for Gastrointestinal Endoscopy (ASGE) has recently released updated guidelines on the use of sedation and anaesthesia for gastrointestinal endoscopic procedures. Almost simultaneously, the American Society of Anesthesiologists (ASA) has brought out practice guidelines for moderate sedation and analgesia. In contrast to the ASA recommendations, ASGE does not view capnography as an essential monitoring modality for endoscopic procedures with moderate sedation because it has apparently not been shown to improve patient safety. However, they do agree that evidence supports its deployment during deep sedation. These differences in views between guidelines published by societies of substantial academic and clinical standing can confuse the agreement over what constitutes standard of care for the particular speciality. It is the expectation that guidelines and consensus statements in anaesthesiology be preferably issued by national or international organizations of the same speciality.
