A nasopharyngeal airway is contraindicated in the following situations:

- Evidence of Battle's Sign (bruising behind the ear)

- Severe facial of cranial injuries.

- Signs of cerebro-spinal fluid (CSF) or raccoon eyes.

NB: the clear fluid coming out of the patient's nose or ears is most likely CSF. CSF protects and insulates the brain, and can leak from the skull if there is head trauma.

The above situations indicate the possibility of a traumatic brain injury (previously termed 'head injury'). The risk of the nasopharyngeal airway intruding with the brain is fairly high so as a precaution, an alternative airway is used. An oropharyngeal airway would be a better alternative in a patient with suspected traumatic brain injury.

A nasopharyngeal airway, (aka NPA or a nasal trumpet), is a tube inserted into the nasal passageway of an unconscious victim to provide an open airway (when unconscious the jaw muscles relax and the tongue to falls back obstructing the airway).

NPA is contraindicated (not used) in patients with severe head or facial injuries, or a basilar skull fracture (Battle's sign, raccoon eyes, cerebrospinal fluid/blood from ears, etc.) due to the possibility of direct contact with brain tissue.

After measuring you decide that the nasopharyngeal airway is too long. What should you do?

If the nasopharyngeal airway is too long, you should trim it to adjust the size. Ensure to measure and cut the airway to the appropriate length based on the patient's anatomy to avoid causing discomfort or injury.
