Injuries to the Face
• Injuries about the face can lead to upper
airway obstructions.
• Bleeding from the face can be profuse.
• Loosened teeth may lodge in the throat.
• If the great vessels are injured, significant
bleeding and pressure may occur.
Soft-Tissue Injuries
• Soft-tissue injuries to
the face and scalp are
common.
• Wounds to the face and
scalp bleed profusely.
• A blunt injury may lead
to a hematoma.
• Sometimes a flap of
skin is peeled back
from the underlying
muscle.
Hematoma
• Blunt injury that does
not break the skin may
cause a break in a
blood vessel wall.
• You and your EMT-B partner receive a call to the
Acme Barn on a report of a fight.
• On arrival, law enforcement personnel advise you
that the scene is safe and that they have the
suspect.

Initial Assessment
• Maintain patient airway.
• Do not insert nasopharyngeal airway if there is
chance of basal skull fracture.
• Quickly assess chest for DCAP-BTLS.
• Place nonrebreathing mask over facial injuries;
may be difficult but is important.
• Quickly assess pulse.
• Control life-threatening bleeding.
Transport Decision
•
•
•
•
Avoid delays in transport.
Consider ALS backup for long transport times.
Monitor constantly.
Significant blow to face or throat may mean spinal
or brain injury.
• You ensure that his airway is open, taking
c-spine precautions.
• No noted airway abnormalities. Breathing
is rapid.
• DCAP-BTLS is unremarkable.
• You control neck bleeding with sterile
dressing and direct pressure; color is bright
red, suggestive of arterial bleeding.
• You start oxygen via nonrebreathing mask
at 10-15 L/min.
• Priority transport
You are the provider
continued
Focused History and Physical Exam
• Rapid physical exam or focused physical exam
depending on injury
• Use DCAP-BTLS to guide you to identify and
correct threats to life.
• Do not focus only on bleeding.
• Obtain baseline vital signs and SAMPLE history.
Interventions
• Complete spinal immobilization if spinal injuries
suspected.
• Maintain open airway.
• Provide high-flow oxygen.
• May need assisted ventilation with BVM device
• Control bleeding.
• Treat for shock if patient has signs of
hypoperfusion.
• Do not delay transport.
Detailed Physical Exam
• Perform if patient is stable and time allows.
Ongoing Assessment
• Reassessment is particularly important with face
and throat injuries.
• These can easily affect respiratory, cardiovascular,
and nervous systems.
• Communication and documentation
– Include description of MOI.
– Estimate amount of blood loss.
– Note specific injuries.
• You must transport rapidly to a trauma center.
• If direct pressure does not control bleeding, apply
pressure above and below wound.
• Secure dressing with bandage over wound and
wrap it under patient’s arm.
• Maintain cervical immobilization.
• Apply pressure to wound en route to trauma center.
You are the provider continued
Care of Soft-Tissue Injuries (1 of 3)
• Assess the ABCs and care for life-threatening
injuries.
• Follow proper BSI precautions.
• Blood draining into the throat can lead to vomiting.
Monitor airway constantly.
• Take appropriate precautions if you suspect a neck
injury.
Care of Soft-Tissue Injuries (2 of 3)
• Control bleeding by
applying direct
pressure.
Care of Soft-Tissue Injuries (3 of 3)
• Injuries around
the mouth may
obstruct the
airway.
Injuries of the Nose
• Blunt trauma to the nose
can result in fractures
and soft-tissue injuries.
• Cerebrospinal fluid
coming from the nose is
indicative of a basal skull
fracture.
• Bleeding from soft-tissue
injuries of the nose can
be controlled with a
dressing.
Injuries of the Ear
• Ear injuries do not
usually bleed much.
• Place a dressing
between the ear and
scalp when bandaging
the ear.
• For an avulsed ear, wrap
the part in a moist sterile
dressing.
• If a foreign body is
lodged in the ear, do not
try to manipulate it.
Facial Fractures
• A direct blow to the
mouth or nose can result
in a facial fracture.
• Severe bleeding in the
mouth, loose teeth, or
movable bone fragments
indicate a break.
• Fractures around the
face and mouth can
produce deformities.
• Severe swelling may
obstruct the airway.
Dislodged Teeth
• Dislodged teeth should
be transported with the
patient in a container
with some of the patient’s
saliva or with some milk
to preserve them.
Blunt Injuries of the Neck
• A crushing injury of the
neck may involve the
larynx or trachea.
• A fracture to these
structures can lead to
subcutaneous
emphysema.
• Be aware of complete
airway obstruction and
the need for rapid
transport to the hospital.
Penetrating Injuries of the Neck (1 of 2)
• They can cause
severe bleeding.
• The airway,
esophagus, and spinal
cord can be damaged
from penetrating
injuries.
• Apply direct pressure
to control bleeding.
• Place an occlusive
dressing on a neck
wound.
Penetrating Injuries of the Neck (2 of 2)
• Secure the dressing in
place with roller gauze,
adding more dressing if
needed.
• Wrap gauze around
and under patient’s
shoulder.
Review
1. When caring for a patient with facial trauma, the
EMT-B should be MOST concerned with:
A. spinal trauma.
B. airway compromise.
C. associated eye injuries.
D. severe external bleeding.
Review
Answer: B
Rationale: No airway, no patient! Injuries to the face
often cause obstruction of the upper airway, either
by clotted blood or associated swelling.
Additionally, large amounts of blood can be
swallowed, which increases the risks of vomiting
and aspiration. Bleeding control, spinal trauma, and
associated injuries are important factors and
should be treated accordingly; however, the airway
comes first.

2. Which of the following mechanisms of injury would
MOST likely cause a crushing injury of the larynx
and/or trachea?
A. Attempted suicide by hanging
B. Gunshot wound to the lateral neck
C. Car crash involving lateral impact
D. Patient whose head hits the windshield
Review
Answer: A
Rationale: Any crushing injury of the upper part of the
neck is likely to involve the larynx or trachea.
Examples include the anterior neck impacting a
steering wheel, hanging (distraction) mechanisms,
and clothesline injuries.
Review
2. Which of the following mechanisms of injury would MOST
likely cause a crushing injury of the larynx and/or trachea?
A. Attempted suicide by hanging
Rationale: Correct answer
B. Gunshot wound to the lateral neck
Rationale: This would produce a penetrating injury.
C. Car crash involving lateral impact
Rationale: This would produce an injury to the spine and
possibly the head.
D. Patient whose head hits the windshield
Rationale: This would produce an injury to the head or a
compression injury to the spine.
Review
3. A 39-year-old man was struck in the face and has a
partially avulsed nose. After taking BSI precautions,
you should:
A. apply oxygen if it is indicated.
B. cover the injury with a sterile dressing.
C. instruct the patient to tilt his head back.
D. assess the status of his airway and breathing.
Review
Answer: D
Rationale: After taking appropriate BSI precautions,
initial care for any facial injury involves assessing
the status of the patient’s airway and breathing.
Facial injuries are often associated with oral
bleeding, which can compromise the airway.
Instruct the patient to lean forward to prevent
drainage of blood down the back of the throat, and
cover the injury with a sterile dressing.
Review
3. A 39-year-old man was struck in the face and has a partially
avulsed nose. After taking BSI precautions, you should:
A. apply oxygen if it is indicated.
Rationale: Airway management is the first priority after BSI.
B. cover the injury with a sterile dressing.
Rationale: This is part of bleeding control after airway
management.
C. instruct the patient to tilt his head back.
Rationale: Do not tilt the patient’s head back. Blood will drain
into the throat and stomach which may cause vomiting and
airway compromise.
D. assess the status of his airway and breathing.
Rationale: Correct answer
Review
4. The presence of subcutaneous emphysema
following trauma to the face and throat is MOST
suggestive of:
A. esophageal injury.
B. cervical spine fracture.
C. crushing tracheal injury.
D. carotid artery laceration.
Review
Answer: C
Rationale: Crushing injuries or fractures of the larynx
or trachea can result in a leakage of air into the soft
tissues of the neck. The presence of air in the soft
tissues produces a characteristic crackling
sensation called subcutaneous emphysema.
Review
4. The presence of subcutaneous emphysema following trauma to
the face and throat is MOST suggestive of:
A. esophageal injury.
Rationale: This will produce bleeding, which may be observed in
the patient’s mouth or through difficulty swallowing.
B. cervical spine fracture.
Rationale: This may be indicated by pain and/or paralysis.
C. crushing tracheal injury.
Rationale: Correct answer
D. carotid artery laceration.
Rationale: This could be assessed by excessive swelling or the
presence of a large hematoma in the neck area.
Review
5. Which of the following statements regarding the
“Adam's apple” is FALSE?
A. It is inferior to the cricoid cartilage
B. It is formed by the thyroid cartilage
C. It is the uppermost part of the larynx
D. It is more prominent in men than in women.
Review
Answer: A
Rationale: The most obvious prominence in the
center of the anterior neck is the Adam's apple.
This prominence is the upper part of the larynx,
formed by the thyroid cartilage. It is more
prominent in men than in women. The other portion
of the larynx is the cricoid cartilage, a firm ridge
that is inferior to the thyroid cartilage.
Review

Review
6. A 21-year-old male has a large laceration to his
neck. When you assess him, you note that bright
red blood is spurting from the left side of his neck.
You should immediately:
A. apply a pressure dressing to his neck.
B. sit the patient up to slow the bleeding.
C. place your gloved hand over the wound.
D. apply 100% oxygen via nonrebreathing mask.
Review
Answer: C
Rationale: Laceration of the carotid artery—as
evidenced by bright red blood spurting from the
wound—can cause profuse bleeding, profound
shock, and death very quickly. You must
immediately control the bleeding with the use of
direct pressure. Cover the wound with your gloved
hand initially and then apply a bulky pressure
dressing. After the bleeding has been controlled,
apply high-flow oxygen and transport promptly.

Review
7. In addition to severe external bleeding, the MOST
immediate concern for a patient who has a large
laceration of the jugular vein is:
A. an air embolism.
B. airway compromise.
C. associated tracheal injury.
D. a life-threatening infection.
Review
Answer: A
Rationale: If a vein has been opened, especially the
large jugular veins of the neck, air can be sucked
through it to the heart, resulting in an air embolism.
A large volume of air in the right atrium and right
ventricle can lead to cardiac arrest.
Review

concern for a patient who has a large laceration of the
jugular vein is:
A. an air embolism.
Rationale: Correct answer
B. airway compromise.
Rationale: This must be evaluated.
C. associated tracheal injury.
Rationale: This must be evaluated.
D. a life-threatening infection.
Rationale: This is not an immediate life threat in the field. It is a
possible problem that may be seen in the hospital setting.

8. Signs of a mandibular fracture include all of the
following, EXCEPT:
A. loose or dislodged teeth.
B. bleeding in the oral cavity.
C. inability to swallow or talk.
D. bruising over the mastoid bone.
Review
Answer: D
Rationale: Signs of a mandibular (lower jawbone)
fracture include loose or dislodged teeth, bleeding
into the oral cavity (mouth), an irregular bite
(malocclusion), and an inability to swallow or talk.
Bruising over the mastoid bone behind the ear
(Battle’s sign) is indicative of a basilar skull
fracture.

Review
9. The nasopharyngeal airway is contraindicated in
patients with:
A. oropharyngeal bleeding.
B. a basilar skull fracture.
C. a large facial hematoma.
D. missing or dislodged teeth.
Review
Answer: B
Rationale: The nasopharyngeal (nasal) airway should
be avoided in patients suspected of having a skull
fracture—specifically basilar or midface fractures. If
a midface fracture is present, the nasal airway
could potentially enter the cranial vault and
penetrate the brain during insertion. Nasal airways
are also contraindicated in patients with nasal
fractures and in those with fluid drainage from the
nose following head or face trauma.
Review
9. The nasopharyngeal airway is contraindicated in patients with:
A. oropharyngeal bleeding.
Rationale: If the patient is bleeding in the back of the throat, a nasal
airway may provide a route for suctioning, using a French catheter.
B. a basilar skull fracture.
Rationale: Correct answer
C. a large facial hematoma.
Rationale: You can use a nasopharyngeal airway if a midface fracture
is not suspected.
D. missing or dislodged teeth.
Rationale: This will not interfere with the use of a nasopharyngeal
airway.

10. The purpose of the eustachian tube is to:
A. move in response to sound waves.
B. transmit impulses from the brain to the ear.
C. equalize pressure in the middle ear when external
pressure changes.
D. house fluid within the inner chamber of the ear and
support balance.
Review
Answer: C
Rationale: The middle ear is connected to the nasal
cavity by the eustachian tube, which permits
equalization of pressure in the middle ear when
external atmospheric pressure changes.
Review
10. The purpose of the eustachian tube is to:
A. move in response to sound waves.
Rationale: This occurs in the tympanic membrane or eardrum.
B. transmit impulses from the brain to the ear.
Rationale: Impulses are transmitted from the ear to the brain.
C. equalize pressure in the middle ear when external pressure
changes.
Rationale: Correct answer
D. house fluid within the inner chamber of the ear and support
balance.
Rationale: Boney chambers in the inner ear support balance.
