Minutes / Content Outline / Master Teaching Notes /
5 / I.  Introduction
A.  During this lesson, students will learn special considerations of assessment and emergency care for a patient suffering eye, face, and neck injuries.
B.  Case Study
1.  Present Dispatch and Upon Arrival information from the chapter.
2.  Discuss with students how they would proceed. / Case Study Discussion
·  Are there any scene hazards that you need to address before approaching the patient?
·  Aside from the patient’s complaint of eye pain and blindness, are there other injuries you should anticipate?
5 / II.  Anatomy of the Eye, Face, and Neck—The Eye
A.  Globe (eyeball)—Sphere approximately one inch in diameter
B.  Sclera—Tough outer coat covering the globe (visible part is “white” of eye)
C.  Cornea—Clear front portion of the eye
1.  Window through which light enters the eye
2.  Extremely sensitive and susceptible to injury
3.  Superficial scratch can cause extreme pain, redness, and flow of tears.
D.  Pupil—Dark center of eye; expands and contracts to control amount of light allowed through lens
E.  Iris—Colored portion of the eye
F.  Lens—Just behind pupil; focuses light on retina
G.  Retina—Back of the eye
H.  Conjunctiva—Lining of inner surface of eyelids and exposed portion of sclera
I.  Anterior chamber—Anterior to iris; filled with watery fluid called aqueous humor
J.  Aqueous humor—Watery fluid that fills anterior chamber
K.  Vitreous body—Behind the lens; filled with clear jelly called vitreous humor
L.  Vitreous humor—Clear jelly that fills the vitreous body
M.  Orbits (eye sockets)—Bony structures of skull that surround the eyes / Teaching Tip
Use anatomical models to review the structures of the eye, face, and neck.
Discussion Questions
·  What is the pupil of the eye?
·  What is the orbit of the eye?
Class Activity
Have each student, without opening the book, draw and label the anatomy of the eye. Then have groups of students compare and compile their drawings and come up with a revised, labeled drawing to turn in for review.
5 / III.  Anatomy of the Eye, Face, and Neck—The Face
A.  The face is comprised of 14 of the skull bones.
1.  13 of the facial bones are immovable.
a.  Orbits of the eyes (eye sockets)
b.  Nasal bones
c.  Zygomatic bones (cheekbones)
d.  Maxillae (fused upper jaw bones)
2.  The mandible (lower jaw) moves on hinged joints.
B.  The face is extremely vascular (contains many blood vessels), so facial injuries may bleed profusely.
C.  Facial bones provide minimum protection for the airway.
D.  Facial bones allow points of attachment for muscles that control facial expression and manipulation of food.
E.  Compromise of facial structure can also cause closed or open brain injury.
F.  Mechanism that causes injury to the face is likely to have injured the spine as well. / Discussion Question
What bones make up the face?
5 / IV.  Anatomy of the Eye, Face, and Neck—The Neck
A.  Body systems within the neck
1.  Cardiovascular—Carotid arteries and jugular veins
2.  Musculoskeletal
3.  Central nervous
4.  Respiratory
5.  Digestive
6.  Endocrine
B.  Major structures of the airway within the neck
1.  Trachea
2.  Larynx
C.  Major concerns with injuries to the neck
1.  Damages to structure of airway are serious life threats.
2.  Any neck injury should automatically be assumed to have caused spine injury. / Discussion Question
What structures are contained in the neck?
Critical Thinking Discussion
What would be the consequences of injury to the thyroid gland in the neck?
15 / V.  Eye, Face, and Neck Injuries—Assessment-Based Approach: Eye, Face, and Neck Injuries
A.  Scene size-up
1.  Think about forces behind injury as soon as you get the dispatcher’s call.
a.  Motor vehicle crash (over 50 percent of all facial trauma cases)
b.  Assault
c.  Sports-related injury
2.  Be prepared to gather information from bystanders as patient is likely to be in great pain and emotionally distraught.
3.  Protect your own safety; call for police backup if assault is involved.
B.  Primary assessment
1.  Establish manual in-line stabilization of the head and neck on first contact.
2.  Control major bleeding with direct pressure.
3.  Open the airway using the jaw-thrust maneuver and suction vomitus and other substances as needed.
4.  Consider advanced life support backup, if available.
5.  If breathing is adequate, provide oxygen at 15 lpm by nonrebreather mask.
6.  If breathing is inadequate, provide positive pressure ventilation with supplemental oxygen at 10–12 ventilations per minute.
7.  Recognize which injuries are high priority for immediate patient transport.
a.  Chemical burns to the eye
b.  Impaled object in the eye
c.  Respiratory distress
d.  Severe injuries to the face or neck
e.  Major bleeding
f.  Airway compromise
C.  Secondary assessment
1.  Inspect and gently palpate for signs of injury to eye sockets, cheekbones, nose, and jaw.
2.  Use a small penlight to examine eyes.
3.  Record vital signs.
4.  If patient is bleeding severely, be prepared to treat shock.
5.  Obtain a history.
6.  Ask questions about the events leading up to the injury.
D.  Reassessment
1.  Conduct a reassessment and check interventions.
a.  For unstable patient, reassess every five minutes.
b.  For stable patient, reassess every 15 minutes.
2.  Monitor for deterioration of mental status, airway, or breathing. / Discussion Question
What are some causes of airway compromise in the patient with injuries to the eye, face, or neck?
