Level of Intended Sedation

Sedation and analgesia is the standard of care during diagnostic and therapeutic endoscopic gastrointestinal procedures in most areas of the world. Unsedated endoscopy is feasible in selected patients, but requires commitment on the part of both the patient and the provider. The American Society of Anesthesiologists has defined four stages of sedation, ranging from minimal to moderate, deep and general anesthesia. The level of sedation as well as the choice of sedative is based on the type of procedure, patient characteristics and the existence of the required structural conditions. Individuals administering sedation/analgesia should be trained to rescue a patient who has reached a level of sedation deeper than that intended.
