Which phase is commonly described as the start of anesthesia when anesthesia is induced and the airway is secured?

• A. Induction
• B. Maintenance
• C. Emergence
• D. NPO

Answer: (A)

Induction. This is the phase when anesthesia begins, involving the administration of agents to render the patient unconscious and typically securing the airway with an endotracheal tube or supraglottic airway. The moment the patient loses consciousness and the airway is protected marks the start of anesthesia, transitioning from the preoperative state into the intraoperative period. After that, the process moves into maintenance, where anesthesia is kept at the right depth for the procedure, while emergence refers to waking up and recovering from anesthesia, and NPO is simply the preoperative instruction meaning nothing by mouth.
