Sensory Emergencies

Eyes, Ears, & Nose


Anatomy

Review in book!

Ch 25 & 26


Eye Parts

  • Conjunctiva

  • Lacrimal Glands

  • Sclera

  • Pupil

  • Iris

  • Cornea

  • Lens

  • Retina

  • Optic nerve

  • Vitreous humor

  • Aqueous humor


Eye Injuries

  • enucleation

  • laceration

  • foreign objects

  • abrasion

  • burns


Eye injuries - notes

  • Signs can be subtle

  • Example - hyphema

    (blood in anterior chamber of eye)


Lacerations

  • Cut to the globe or surrounding tissue

  • Never exert pressure on or manipulate the eye

  • If part of eyeball is exposed, apply a moist, sterile dressing and eye shield


small foreign objects - irrigate with saline

Flush from the nose outward

Never attempt to remove an object on the cornea

Foreign Objects in the Eye


Impaled Object

  • Do not remove it

  • Immobilize the object in place

  • Moist sterile dressing over the injured eye only*

    *LA county


Chemical Burns

  • Irrigate - Irrigate - Irrigate

  • Use water or saline solution

  • 20 minutes

  • powder or liquid = irrigate

  • Dry dressing


Thermal Burns

  • Usually to the eyelid

  • Cover both eyes with a moist, sterile dressing and eye shield

  • Transport supine to burn center.


Light Burns

  • Infrared rays, eclipse light, direct sunlight, laser burns

  • Welding without protection

  • Burns on cornea

  • Very painful

  • Cover eyes with sterile pad and eye shield.

  • Transport supine


other...

Not Trauma Related

  • blurred vision

  • double vision

  • sudden blindness

    Think CVA or other neurological


Eye Injuries Following a Head Injury

  • One pupil larger than the other

  • Eyes not moving together

  • Failure of the eyes to follow equally

  • Bleeding under the conjunctiva

  • Protrusion or bulging of one eye


Contact lenses

  • Leave in place unless chemical burn

  • Trying to remove them can damage cornea

  • If irrigation removes them - fine

  • If patient removes them - fine

  • If there is no function in an eye, ask if the patient has an artificial eye


Ear Anatomy

  • External ear

  • Middle ear

  • Inner ear


Injuries of the Ear

  • Doesn’t usually bleed much.

  • Place a dressing between ear and scalp

  • For avulsion, moist sterile dressing.

  • Do not try to remove a foreign body

  • CSF/blood

  • Ruptured tympanic membrane


Ears - notes

  • ringing in ears

  • sudden deafness - CVA?

  • Inner ear infections - Vertigo


Nasal Anatomy

  • Septum

  • Turbinates

  • Frontal sinus


Injuries of the Nose

  • Blunt trauma can cause fractures and soft-tissue injuries.

  • CSF/blood

  • Use dry sterile dressing for soft tissue injuries

  • Object inserted in nose can be removed if freely movable

  • Impaled objects get bulky dressing


Nose Bleeds

  • Lean forward

  • Pinch nostrils and hold

  • Blood is an irritant to the stomach

  • Hypertensive?
