Local anesthesia for endotracheal intubation

Local anesthesia for endotracheal intubation represents a procedural intervention rather than a distinct primary disease state

It targets the upper respiratory tract—specifically the sensory pathways of the nasopharynx, oropharynx, larynx, and trachea—in pediatric or adult patients undergoing airway instrumentation

Mechanistically, local anesthetic agents inhibit voltage-gated sodium channels in mucosal nociceptors, thereby blunting the noxious sensory stimuli caused by laryngoscopy and tube placement

This localized desensitization suppresses protective airway reflexes, such as coughing and laryngospasm, while attenuating adverse sympathoadrenal responses, including tachycardia, hypertension, and intracranial pressure spikes
