Which stage of anesthesia should be attained before tracheal intubation?

Explanation:
The airway should be secured once the patient has reached surgical anesthesia depth, where protective airway reflexes are suppressed and muscle tone is relaxed. At this depth, laryngeal reflexes are diminished and ventilation can be established smoothly, reducing the risk of coughing, gagging, or laryngospasm during intubation. Intubating too early (during lighter anesthesia) can trigger reflexes and movement; waiting too long (into overdose) risks apnea and cardiovascular depression. Typical indicators of this depth include loss of consciousness, loss of eyelash reflex, regular and controlled breathing, and reduced jaw muscle tone, often followed by appropriate muscle relaxation for intubation.
