deep sedation
A drug-induced depression of consciousness from which the patient is not easily aroused but responds purposefully to repeated or painful stimulation, potentially with compromised airway reflexes.
Full Definition
Deep sedation occupies the level immediately below moderate sedation and above general anesthesia on the sedation continuum. Patients under deep sedation may not maintain their airway independently and may have partial or fully impaired protective reflexes, necessitating readiness for airway management interventions. Spontaneous ventilation may be inadequate, and cardiovascular function is usually maintained. In dental anesthesiology, deep sedation is often employed for highly anxious patients, pediatric patients, or lengthy surgical procedures, and it requires personnel qualified in advanced airway management. Because patients can drift from deep sedation into general anesthesia, this level demands vigilant monitoring including capnography and continuous assessment of sedation depth.
Usage
Usage note: Editors must distinguish 'deep sedation' from 'general anesthesia.' The line between them is clinically significant and legally relevant in state dental board regulations. Never conflate the two in regulatory or credentialing documents.
