When should caution be exercised with a nasopharyngeal airway insertion?

Caution should be exercised with nasopharyngeal airway insertion in patients with a suspected skull fracture because of the risk of further injury or complications. A nasopharyngeal airway is designed to be inserted through the nose and into the pharynx to maintain an open airway. However, in the case of a skull fracture, particularly those involving the base of the skull, there is a significant risk that the insertion of the airway could penetrate the cranial cavity or exacerbate existing injuries. This could lead to complications such as intracranial hemorrhage or infection.

For patients who are deeply unconscious, although caution is needed, the nosopharyngeal airway is often indicated to secure the airway, as they may not have protective gag reflexes. In patients with severe respiratory distress, the primary focus would be on securing the airway and ensuring adequate ventilation. Similarly, in stable patients, the use of a nasopharyngeal airway is typically safe and may be beneficial if an airway needs to be maintained. The key concern in the context of airway management is the avoidance of further neurological compromise in patients with suspected cranial injuries.
