Abstract:
Two patients who had undergone emergency tracheal intubation developed signs of aspiration of ingested food. Nasendoscopy demonstrated supraglottic anaesthesia which recovered from the laryngeal margins in towards the vocal cords. It is assumed that this was caused by a neuropraxia of the internal branch of the superior laryngeal nerve, presumably as a result of trauma related to intubation.

Endotracheal Intubation I: Procedure
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...

1. Nursing Care of Patients Before Intubation
Before the endotracheal intubation procedure, nurses play an essential role in ensuring the process goes smoothly. The nurses must be familiar with intubation...
Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals.
