0 an examination of the throat, including the parts that create the voice, using a long thin tube: --
The tracheal tube exchanger is a hollow catheter, 56to81cmin 1 in length, that can be used for removal and replacement of tracheal tubes without the need for laryngoscopy.
This aid is commonly used with a difficult laryngoscopy.
Lidocaine is also theorized to blunt a rise in intracranial pressure during laryngoscopy, although this remains controversial and its use varies greatly.
However, these devices require a different skill set than that employed for conventional laryngoscopy and are expensive to purchase, maintain and repair.
More often, a doctor or a trained speech-language pathologist diagnoses laryngeal papillomatosis by an indirect laryngoscopy in the office.
He published several books on laryngoscopy and diseases of the throat.
In the prehospital emergency setting, digital intubation may be necessitated if the patient is in a position that makes direct laryngoscopy impossible.
Personnel experienced in direct laryngoscopy are not always immediately available in certain settings that require emergency tracheal intubation.
