The Guidelines also exclude patients who are not undergoing a diagnostic or therapeutic procedure ( e.g.В , postoperative analgesia, sedation for treatment of insomnia). Examples of minimal sedation include peripheral nerve blocks, local or topical anesthesia, and either (1) less than 50% nitrous oxide (N 2O) in oxygen with no other sedative or analgesic medications by any route, or (2) a single, oral sedative or analgesic medication administered in doses appropriate for the unsupervised treatment of insomnia, anxiety, or pain. Because minimal sedation (anxiolysis) entails minimal risk, the Guidelines specifically exclude it.

These Guidelines are designed to be applicable to procedures performed in a variety of settings ( e.g.В , hospitals, freestanding clinics, physician, dental, and other offices) by practitioners who are not specialists in anesthesiology. * Reflex withdrawal from a painful stimulus is not considered a purposeful response.Дeveloped by the American Society of Anesthesiologists approved by the ASA House of Delegates October 13, 1999. Individuals administering Moderate Sedation/Analgesia (Conscious Sedation) should be able to rescue patients who enter a state of Deep Sedation/AnalgesiaВ , while those administering Deep Sedation/Analgesia should be able to rescue patients who enter a state of general anesthesia. Hence, practitioners intending to produce a given level of sedation should be able to rescue patients whose level of sedation becomes deeper than initially intended. Cardiovascular function may be impaired.Д«ecause sedation is a continuum, it is not always possible to predict how an individual patient will respond. Patients often require assistance in maintaining a patent airway, and positive pressure ventilation may be required because of depressed spontaneous ventilation or drug-induced depression of neuromuscular function. The ability to independently maintain ventilatory function is often impaired. General AnesthesiaВ = a drug-induced loss of consciousness during which patients are not arousable, even by painful stimulation. Cardiovascular function is usually maintained. Patients may require assistance in maintaining a patent airway, and spontaneous ventilation may be inadequate. The ability to independently maintain ventilatory function may be impaired. Cardiovascular function is usually maintained.Дeep Sedation/AnalgesiaВ = a drug-induced depression of consciousness during which patients cannot be easily aroused but respond purposefully following repeated or painful stimulation. No interventions are required to maintain a patent airway, and spontaneous ventilation is adequate. Moderate Sedation/Analgesia (Conscious Sedation)В = a drug-induced depression of consciousness during which patients respond purposefully to verbal commands, either alone or accompanied by light tactile stimulation.

Although cognitive function and coordination may be impaired, ventilatory and cardiovascular functions are unaffected. Minimal Sedation (Anxiolysis)В = a drug-induced state during which patients respond normally to verbal commands.
