Induction Agent
A rapidly acting intravenous or inhalational drug administered to transition a patient from consciousness to an anesthetized state suitable for dental procedures.
Full Definition
An induction agent produces loss of consciousness quickly and smoothly, allowing airway management and surgical access to be established. In dental anesthesiology, commonly used induction agents include propofol, ketamine, and sevoflurane (via inhalation mask). The choice depends on the patient's medical history, procedure type, and anticipated recovery profile. Editors must take care not to conflate induction agents with maintenance agents, as a drug may serve both roles (e.g., sevoflurane) or only one (e.g., high-dose propofol bolus for induction followed by infusion for maintenance).
Usage
Usage note: Do not use interchangeably with 'sedative'; induction implies loss of consciousness, whereas sedation exists on a continuum.
