2024
Presented here is a protocol for awake nasotracheal intubation using a flexible rhino-laryngoscope with a 300 mm working length. As this tool is minimally invasive and easy to manipulate, awake intubation performed with a flexible rhino-laryngoscope is well-tolerated, fast, and safe for patients with difficult airways.

We illustrate non-surgical delivery of test materials into the lungs of anesthetized mice via the trachea. This method permits lung exposure to bacterial and viral pathogens, cytokines, antibodies, beads, chemicals, or dyes. We further describe harvesting and processing of lungs and lung draining lymph nodes (LDLNs) for flow cytometry.

The method described here allows for the visualization of IL-8 promoter-dependent inflammation activation in the lungs of mice through non-invasive bioluminescence imaging (BLI). The same animal can be subjected to BLI multiple times for up to two months from the time of delivery of the luciferase reporter construct.

FAQs
Blade selection and positioning directly influence the view of the glottis. During direct laryngoscopy, the blade must pass through the mouth, displace the tongue, and lift or control the epiglottis to create a line of sight. Choosing an appropriate blade and positioning the patient effectively can improve visualization and make airway management more controlled.
Direct laryngoscopy depends on a direct line of sight from the operator to the larynx after the blade controls the tongue and epiglottis. Video laryngoscopy instead uses a camera near the blade to transmit an enlarged image. This difference changes how the glottis is viewed and provides an alternative approach when assessing the airway or placing a breathing tube.
Gentle technique helps balance adequate visualization with protection of oral and laryngeal tissues. Excessive force or poor control can increase the risk of dental or soft-tissue trauma, whereas careful blade handling supports the intended view of the glottis. This principle is especially important when the instrument is used for airway assessment or endotracheal intubation.
The clinician selects and positions the laryngoscope, introduces the blade through the mouth, and uses it to displace the tongue and lift or control the epiglottis. The resulting view helps identify the glottis and supports breathing-tube placement when endotracheal intubation is required. Video equipment may transmit an enlarged image from a camera near the blade.
Laryngoscope use is relevant whenever clinicians need to assess or manage the airway in emergency or anesthetic settings. It can support visualization of the larynx and vocal cords, facilitate placement of an endotracheal breathing tube, and help establish airway control. The same general purpose applies across urgent airway management and planned anesthetic care.
Beyond supporting intubation, laryngoscope use can provide visualization of the larynx and vocal cords during clinical evaluation. This view may help clinicians examine the laryngeal region when abnormalities are suspected. Direct and video approaches offer different viewing arrangements, while appropriate positioning, blade selection, and gentle handling support a clearer examination with less tissue trauma.
