Clinical Focus on Transferring Facial Injuries<br />

v) Finally, does the patient need to be<br />

transferred with full spinal protection? If<br />

so intubation prior to transfer should be<br />

considered.<br />

Assessing the airway - Although a talking<br />

patient is encouraging, when facial injuries<br />

are evident this is no safeguard against<br />

airway threats. The mouth and throat should<br />

always be inspected. Oral and nasal bleeding<br />

can continue unseen. Foreign and loose<br />

bodies (especially dentures and detached<br />

teeth) should be removed. Unfortunately,<br />

correctly fitting rigid collars restrict mouth<br />

opening and make assessment difficult,<br />

but if the potential for airway compromise<br />

exists, these should be loosened enough to<br />

enable examination (during which, in-line<br />

manual immobilisation of the neck can be<br />

performed).<br />

If the risk of spinal injury is considered low,<br />

the airway is best managed by allowing<br />

the patient to position themselves upright,<br />

thereby maintaining their own airway<br />

patency. However, following high-energy<br />

trauma, the presence of actual or potential<br />

injuries elsewhere may preclude this<br />

approach and the airway may need to be<br />

secured prior to transfer. The presence<br />

of coexisting brain injury and the need<br />

to maintain effective ventilation are other<br />

important considerations.<br />

Current guidelines for intubation in<br />

maxillofacial injuries are a little vague and<br />

can be misleading. For example, bilateral<br />

fractures of the mandible are a common<br />

injury, frequently cited as an indication for<br />

intubation. But they rarely require this. It is<br />

only when they occur in combination with<br />

a reduced Glasgow coma scale (GCS) or<br />

spinal immobilisation that they become a<br />

significant risk. Other indications related<br />

specifically to facial trauma would include<br />

i) when gross swelling is anticipated, ii) in<br />

order to facilitate control of haemorrhage<br />

or iii) in ‘significant’ facial injuries where a<br />

long duration transfer is expected. However,<br />

the definition of ‘significant’ requires clinical<br />

judgement on a case-by-case basis and is<br />

often based on the mechanism of injury.<br />

If all else fails advanced airway management<br />

techniques may be necessary, including<br />

surgical airways. These are well described<br />

elsewhere and are therefore not detailed<br />

here.<br />

2 B (breathing). Aside from the need for<br />

oxygen administration and monitoring,<br />

breathing problems are rarely associated<br />

with facial trauma. However avulsed teeth<br />

and dentures can be occasionally aspirated,<br />

resulting in partial blockage of the bronchial<br />

tree. This should be considered in any<br />

patient with isolated facial injuries but<br />

who appears to have asymmetric signs of<br />

respiration.<br />

3 C (circulation). Life-threatening blood<br />

loss arising from scalp lacerations and facial<br />

injuries is relatively uncommon, although<br />

bleeding can still be significant, especially in<br />

children.<br />

i) In the hypotensive patient, active<br />

bleeding may be minimal when first<br />

encountered, and it is only when the blood<br />

pressure improves during resuscitation<br />

that bleeding, both obvious and occult,<br />

recommences. This may have significant<br />

implications with transfers.<br />

ii) Blood loss from occipital scalp<br />

lacerations and even relatively ‘minor’ facial<br />

injuries such as nasal fractures can be missed<br />

in supine immobilised patients and although<br />

haemorrhage may not necessarily be rapid, it<br />

may continue uncontrolled over a prolonged<br />

period of time.<br />

A large scalp laceration. Unless pressure is applied<br />

this would result in significant blood loss. Care<br />

would be required with tight dressings, in case<br />

there were large skull fractures underneath.<br />

iii) Control of haemorrhage can be very<br />

difficult, even within the relative safety of<br />

the emergency department. Intubation<br />

may often be required in order to facilitate<br />

effective control. This takes the form of<br />

packing of the oral cavity and nose - the<br />

latter of which is a concern if skull base<br />

fractures are present. Nevertheless, some<br />

form of tamponade is required and<br />

the patient should not be left to slowly<br />

exsanguinate on the basis of a perceived risk.<br />

This is a very difficult area of clinical practice.<br />

iv) Packing of the oral cavity also<br />

requires unrestricted access to the oral<br />

cavity, necessitating the unfastening of the<br />

cervical collar - the cervical spine must<br />

remain carefully immobilised, making this (at<br />

the least) a two person job.<br />

v) Actively bleeding cutaneous wounds,<br />

such as the scalp, can simply be closed with<br />

staples, any strong suture to hand, or by<br />

applying a pressure bandage.<br />

vi) Epistaxis, either in isolation or<br />

associated with midface fractures, may be<br />

controlled using a variety of specifically<br />

designed nasal balloons or packs. These<br />

must be used with care if there are mobile<br />

midface fractures - overpacking can distract<br />

the fractures further resulting in further<br />

tissue damage and bleeding. Nasal packs<br />

are not without risk - toxic shock, sinusitis,<br />

meningitis, and brain abscess are all potential<br />

complications. Blindness has also been<br />

reported.<br />

If haemorrhage persists despite these<br />

interventions, it is important to consider<br />

pre-existing or acquired coagulation<br />

abnormalities; only rarely is operative<br />

surgical control of facial bleeding required<br />

in theatres during the primary survey<br />

(following blunt trauma).<br />

4 D (disability). By virtue of their close<br />

proximity to the skull, high energy facial<br />

fractures are frequently associated with<br />

varying degrees of brain injury or disruption<br />

of the skull base. Therefore it is important<br />

that the Glasgow Coma Scale or AVPU<br />

score is carefully noted and regularly<br />

reassessed. The management of patients<br />

with coexisting head injuries is not discussed<br />

in this article. Interestingly, the geometry of<br />

the facial skeleton has been likened to the<br />

chassis of a car. At the moment of impact,<br />

horizontal struts of bone “buttresses”<br />

collapse, thereby preventing the kinetic<br />

energy being transferred to the brain (the<br />

‘driver’). Effectively, it is argued, the facial<br />

skeleton has evolved into a ‘‘crumple<br />

zone’’. Despite this survival advantage, the<br />

combination of extensive vascularity of the<br />

face and its lack of deep fascia can still result<br />

in significant blood loss and swelling.<br />

E (eyes) - Although “E” normally refers to<br />

exposure, from a maxillofacial perspective<br />

visual loss is the next priority once i) the<br />

airway has been secured, ii) facial bleeding<br />

controlled and iii) any significant brain<br />

injury treated or excluded. Arguably, visionthreatening<br />

injuries are just as important to<br />

the patient as limb-threatening problems,<br />

especially if they involve both eyes. Early<br />

identification of sight-threatening conditions<br />

may be possible when the pupils are<br />

assessed along with the GCS. At this time<br />

the vision can be checked and obvious<br />

ocular findings can be noted. At the<br />

roadside, vision-threatening injuries that<br />

need rapid identification are perforated or<br />

ruptured globes, significant bulging of the<br />

eye (proptosis - in essence a compartment<br />

syndrome of the eye socket), and loss of<br />

eyelid protection. Whilst other conditions<br />

exist, there is little that can be done at<br />

this stage. Useful symptoms and signs of<br />

significant globe injury include.<br />

i) Loss of vision<br />

ii) Severe pain in or around the eye<br />

iii) An agitated patient with signs of injury<br />

around the eye<br />

iv) Significant proptosis of the globe<br />

A real skull,<br />

fragile many of<br />

the bones of<br />

the face are.<br />

Light can easily<br />

pass, especially<br />

though the orbits<br />

and anterior<br />

skull base’.<br />
