A fiberoptic nasopharyngoscope is a handy tool to check patients for suspected foreign bodies (e.g. fishbone stuck in throat) or laryngeal edema. Depending on the diameter of your fiberoptic cable, it may be fairly uncomfortable for the patient despite generous viscous lidocaine instillation through the nares and nebulized lidocaine. Alternatively or additionally, you can make your own lidocaine-oxymetazoline nasal atomizer which works well.
What if the patient is STILL not tolerating the procedure well?
