Topical Airway Anesthesia for Awake-endoscopic Intubation Using the Spray-as-you-go Technique with High Oxygen Flow

The topical anesthetic lidocaine was atomized using a high oxygen flow through the working channel of a flexible intubating endoscope to achieve topical airway anesthesia for awake endotracheal intubation. We prefer this modified spray-as-you-go technique for endoscopic intubation to classical bolus application because of higher patient satisfaction and better compliance.

In pandemic times, medical staff is becoming a key resource in fighting the infection. To achieve the best medical care, relevant techniques and procedures have to be taught to medical staff to reduce the risk of infection. COVID patients often need mechanical ventilation due to progredient respiratory insufficiency, so an endotracheal intubation becomes a critical procedure in managing these patients. This procedure has an increased risk of infection due to aerosol formation and working with...

FAQs
Local anesthetic agents act on sensory nerve membranes within the treated mucosa by temporarily blocking voltage-gated sodium channels. This prevents sensory nerves from initiating and transmitting pain signals when the agent contacts the airway lining. The resulting interruption reduces discomfort during airway procedures without requiring the sensory signal to reach higher neural pathways.
These protective responses depend on sensory stimulation from the airway lining. By reducing the transmission of signals from mucosal surfaces, anesthesia decreases the sensory input that can trigger gagging, coughing, and laryngeal reactions. This suppression can make airway manipulation more tolerable while supporting patient cooperation during procedures performed with the patient awake.
Treatment may involve sensory surfaces lining the nose, mouth, pharynx, larynx, or trachea. The relevant region depends on the planned airway management or diagnostic intervention, because different procedures contact different portions of the airway. Recognizing the intended site helps clinicians direct the anesthetic to surfaces involved in discomfort or protective reflexes.
Dose and administration must provide sufficient mucosal anesthesia while maintaining airway safety. Too little effective treatment may leave discomfort and protective reflexes inadequately controlled, whereas poorly managed administration can undermine the safety balance emphasized for airway procedures. Careful attention to both the amount used and how it contacts the mucosa is therefore essential.
The anesthetic is applied through a topical or regional approach so it contacts the sensory mucosa involved in the planned intervention. After the targeted surface is numbed, clinicians can proceed with airway management or diagnostic examination while aiming to reduce discomfort and reflex responses. The approach is selected according to the airway region the procedure will engage.
Clinicians use this approach during bronchoscopy, awake intubation, endoscopic examination, and other airway interventions. Its value is greatest when instrumentation could provoke discomfort, gagging, coughing, or laryngeal responses. By reducing those reactions, the technique helps support procedural tolerance and patient cooperation during examinations or airway management performed without relying solely on deeper anesthesia.
During awake intubation and related airway management, reducing sensory stimulation can limit discomfort and protective reflexes while the patient remains cooperative. The overview also emphasizes preservation of spontaneous breathing, making the technique relevant when clinicians need airway access without eliminating the patient’s ongoing respiratory effort. Appropriate dosing remains central to maintaining this balance.
