Maxillofacial injuries can occur in car accidents, sports, violent incidents and more. They may block the airway and cause breathing difficulty. Therefore, keeping the airway open is the primary step in preventing serious complications. In these cases, a nasopharyngeal airway (NPA) is commonly utilized to assist patients to breathe. But why is it the preferred choice for maxillofacial injuries? Now, take several minutes here to get the reasons.
Maxillofacial injuries can affect the patient's appearance and even threaten his or her life. They are often accompanied by various traumas in the oral cavity, such as:
Oral or facial soft tissue lacerations
Broken or loose teeth
Oral bleeding
Tongue swelling or displacement
Etc.
If an oropharyngeal airway (OPA) is used for such injuries, it may further irritate the oral trauma site and even push blood or tooth fragments into the airway, causing more severe obstruction. In addition, oral injuries may cause pain and discomfort, making it difficult for patients to accept the OPA's insertion.
In contrast, the nasopharyngeal airway tube is inserted through the nasal cavity, bypassing the mouth and directly entering the throat. This reduces the risk of suffocation caused by oral trauma. Maintaining airway patency is essential, especially when the patient is still breathing independently but has partial airway obstruction.
When choosing an airway device, it's important to check if the patient is conscious and has a gag reflex.
OPA is for unconscious patients with no gag reflex. It can trigger vomiting if used on a semi-conscious person, leading to choking.
NPA does not trigger the gag reflex and is safe even if the patient is awake or semi-conscious.
For facial injury patients, avoiding choking is critical. NPAs lower the risk of aspiration (inhaling vomit), which could lead to pneumonia or suffocation.
PVC Nasopharyngeal Airway (Trumpet Type)
Facial injuries often include:
Broken jaw or cheekbone
Dislocated jaw joint
Swelling or bruising on the face
These injuries make opening the mouth painful or impossible. Forcing an OPA into the mouth may cause more pain or worsen the injury.
An NPA does not require the mouth to open. It slides in through the nose, avoiding pressure on broken bones and allowing the patient to breathe without extra pain or risk.
Facial injuries can also affect tongue movement, leading to:
The tongue falls back due to lost support from broken bones
Swelling from internal bleeding
Relaxation of tongue muscles in semi-conscious patients
An NPA helps keep the airway open by preventing the tongue from blocking airflow. Made of soft materials like silicone or PVC, it provides support while reducing discomfort.
Although the nasopharyngeal airway is widely used in maxillofacial trauma, it is not suitable for all patients, especially in the following cases, it should be used with caution or avoided:
If your patient has a basilar skull fracture, there may be a risk of the nasal cavity communicating with the skull. At this time, inserting a nasopharyngeal airway may cause the catheter to accidentally enter the cranial cavity, causing serious complications. Therefore, it's safe to choose endotracheal intubation or cricothyroidotomy for airway management instead.
Some patients may have congenitally deviated nasal septum, nasal obstruction, swelling, or bleeding due to trauma. In this case, inserting a nasopharyngeal airway may be difficult to pass, and may even cause nasal mucosal damage or further bleeding. At this time, the doctor will evaluate and decide whether to use alternative options, such as endotracheal intubation.
