How is laryngoscopy performed?
Generally, laryngoscopy is a method of examining laryngeal tissues using a flexible endoscope. The specific procedure is as follows:
1. Verify the patient's information before the examination and confirm the indications and contraindications.
2. Position the patient in the supine position and disinfect the patient's face.
3. Spray the anesthetic tetracaine into the nose and mouth to achieve local anesthesia of the nasal and oral mucosa.
4. After anesthesia has taken effect, slowly insert the laryngoscope through the nasal cavity and pharynx to reach the larynx.
5. Examine the pharynx, larynx, and surrounding tissues for any abnormalities and record images as needed.
Laryngoscopy should be performed at a正规 hospital by qualified medical professionals.
