Minimal Sedation
The lightest recognized level of CNS depression induced by a pharmacological agent, during which the patient responds normally to verbal commands and all protective reflexes remain intact.
Full Definition
Minimal sedation, formerly termed 'anxiolysis' at its most basic level but defined separately in regulatory contexts, represents the first tier of the continuum of sedation. At this level, cognitive function and coordination may be mildly impaired, but ventilatory and cardiovascular functions are unaffected. In dental practice, nitrous oxide inhalation or low-dose oral benzodiazepines are the most common means of achieving minimal sedation. Editors must distinguish this term from 'moderate sedation,' which requires a higher level of practitioner qualification. Regulatory bodies such as state dental boards assign specific permit requirements based on the level of sedation administered.
Usage
Usage note: Do not hyphenate as a compound modifier when used predicatively (e.g., 'the sedation was minimal'); hyphenate when used attributively before a noun (e.g., 'a minimal-sedation permit').
