Laryngoscopy • • • Definitions and descriptions: - Allows direct visualisation of the glottis. - It has a Macintosh (curved blade), which is designed to rest in the epiglottic vallecula when the laryngoscope is elevated, the epiglottis is lifted to allow the visualisation of the larynx. - The miller blade is preferred in young children. It is a straight blade that is designed to life the epiglottis directly, which is often bulkier compared to adults. Indications - Clearing the airway - Insertion of an endotracheal tube. - Insertion of a gastric tube. Contraindications - • • Epiglottitis. Complications - Laryngospasms - Hypoxemia due to delays in oxygenation which performing the procedure. - Trauma to the mouth or upper airway, especially the teeth/dentures. - Exacerbations of underlying C-spine injuries. - Failure to visualise glottis. Procedure - Ensure the patient’s oxygenation is optimised prior to the laryngoscopy. - Ensure comprehensive non-invasive monitoring. - Place the patient’s head in the sniffing position or implement MILS if a C-spine injury is suspected. - Open the mouth and inspect oral cavity, removing dentures or debris as required. • - Using the left hand, place the laryngoscope into the right side of the patient’s mouth, gently sweeping the patient’s tongue to the left. - Elevate the laryngoscope to lift the mandible without levering on the teeth. The end of the blade should rest in the epiglottic vallecula, allowing direct visualisation of the larynx. Other important information: - Laryngoscopy is not advised in patients with intact airway reflexes. - It is possible to use a blade which is larger than needed and still visualise the glottis effectively. However, using a blade which is inappropriately small with make an adequate laryngoscopy impossible.
