NASOPHARYNGEAL AIRWAY, Robertazzi type

Definition

A nasopharyngeal airway (NPA) is a soft, flexible, uncuffed tube placed through the nasal passages so that the distal tip rests in the nasopharynx. It is used to maintain the free passage of air to and from the lungs. The purpose of the flared end is to prevent the device from becoming lost inside the patient's nose.

Synonym

also known as an NPA, nasal trumpet (because of its flared end), or nose hose

Instructions for use

The correct size NPA is chosen by measuring the device on the patient: the device should reach from the patient's nostril to the earlobe or the angle of the jaw. In addition, choose an NPA which has a diameter a little smaller than the patient's nares. The distal tip of the NPA is properly placed beyond the tongue base but should not be in contact with the epiglottis.

Precautions for Use

Insertion of an NPA is absolutely contraindicated in patients with severe head or facial injuries, or have evidence of a basilar skull fracture due to the possibility of direct intrusion into brain tissue.

MSF requirements

The nasopharyngeal airway has advantages over the oropharyngeal airway (Guedel airway) in certain situations as it can be used in patients with an intact gag reflex, trismus or oral trauma.
