moderate sedation
A drug-induced depression of consciousness in which the patient responds purposefully to verbal commands or light tactile stimulation and maintains independent airway patency and ventilation.
Full Definition
Moderate sedation, formerly termed 'conscious sedation,' describes an intermediate sedation level in which the patient is drowsy and cooperative but can be aroused with verbal or light physical stimulation. Protective airway reflexes remain intact, and no interventions are required to maintain a patent airway or spontaneous respiration. In dental anesthesiology, moderate sedation is commonly achieved with oral benzodiazepines, nitrous oxide combined with an opioid, or intravenous agents such as midazolam and fentanyl. Regulatory bodies, including most U.S. state dental boards, issue specific permits for dentists who perform moderate sedation. Editors should note that the older term 'conscious sedation' has been officially replaced in most authoritative guidelines and should be updated accordingly when editing clinical or regulatory documents.
Usage
Usage note: The term 'conscious sedation' is considered outdated in current ADA and ASA guidelines. Editors should replace it with 'moderate sedation' in clinical, regulatory, and educational texts unless a historical context requires the original term.
