Lecture 17 - Head and Face Injuries Flashcards
what type of sport do face and head injuries occur in?
- collision and contact sports
what is the best way to prevent injuries to the head and face?
- education
- protective equipment
what is the cause of facial lacerations?
- penetrating/sharp object or blunt trauma causing direct or indirect compressive force
what are the signs of facial lacerations?
- pain
- substantial bleeding (especially overtop bones)
- (skin cuts very easily)
how do you care for facial lacerations?
- clean with sterile saline
- assess for debris or damage to structures
- apply pressure to control bleeding
- rule out skull/brain trauma
- refer to physician (preferably plastics) for stitches if necessary
what is the cause of scalp injuries?
- blunt trauma or penetrating trauma (usually)
- can occur in conjunction with serious head trauma
what are the signs of scalp injuries?
- blow to the head
- bleeding is extensive and difficult to pinpoint (highly vascular area)
how do you care for scalp injuries?
- clean with antiseptic soap and water
- remove debris
- cut away hair (if necessary to expose area)
- apply pressure to reduce/stop bleeding
- use ice to reduce blood flow
- refer wounds larger than 1/2 inch in length
- treat smaller wounds with protective covering/gauze
when should you refer someone for stitches?
- high tension location (elbow, knee, face, etc.)
- wounds >4 cm in length
- cut goes through all skin layers (showing fat, tendon, bone or vessels)
- within 8-12 hours (ideally within 4-6 hours)
- protect with non-medicated gauze if sending for sutures
how do you care for lacerations that do not require stitches?
- steri-strips
- butterfly bandage
what causes brain injuries?
- a result of a direct blow
- compressive force
- tensile (negative pressure) force
- shearing
what is the purpose of CSF?
- (cerebral spinal fluid)
- converts focal force into compressive stress
- dissipates force over brains full surface
- has minimal impact on shearing force (especially when combined with rotation)
what is battle’s sign? (aka periauricular ecchymosis)
- bruising around the ear (behind the ear)
- indicates a skull fracture
- late finding (24-48 hours after incident)
what is raccoon eyes? (aka periorbital ecchymosis)
- bruising around/under the eyes
- indicates a skull fracture
- late finding (24-48 hours after incident)
what is halo sign?
- clear (yellowish/greenish) drainage that separates from bloody drainage from ears/nose
- indicative of CSF leakage
- indicates skull fracture
what is the PEARL test for vision?
- Pupils Equal And Reactive to Light
- indicates normal eye function
what do equal but dilated/unresponsive pupils indicate?
- cardiac arrest
- CNS injury
what do equal but constricted/unresponsive pupils indicate?
- CNS injury or disease
what do unequal, one dilated/responsive pupils indicate?
- CVA (cerebrovascular accident)
- head injury
- direct trauma to the eye
what is an Epidural Hematoma?
- bleeding between the dura and skull
what is the cause of an epidural hematoma?
- blow to the head
- skull fracture
- tearing of meningeal arteries
- blood accumulation and pressure occur rapidly (minutes to hours)
what are the signs of an epidural hematoma?
- possible brief loss of consciousness followed by lucidity
- gradual progression of signs and symptoms
- severe head pain
- dizziness
- nausea
- dilation of one pupil (anisocoria), on side of the injury
- determination of consciousness
- slowing pulse and respiration (lethargic)
- convulsion
what is the care for an epidural hematoma?
- requires urgent neurosurgical care
- relieve pressure to avoid disability or death
what is a subdural hematoma?
- bleeding under the dura mater in the brain
what is the cause of a subdural hematoma?
- the result of acceleration/deceleration forces
- tearing of the vessels that bridge dura matter and brain
- venous bleeding (little to no damage to the cerebellum, complicated bleeds can damage the cortex)
what are the acute signs of a subdural hematoma?
- LOC in seconds to minutes
- pupillary asymmetry
- headache
- dizziness
- nausea
- sleepiness (if not unconscious)
- falling in and out of consciousness quickly
what is the care for a subdural hematoma?
- immediate emergency medical attention
- CT or MRI to determine extent of injury
how long should you monitor an athlete following head trauma?
- 4-6 hours
- don’t send them home alone
- if in doubt, check it out
what are the steps to recognizing and managing facial injuries?
- assess (ABC’s)
- manage significant bleeding
- check nose and ears for CSF
- take a top-down approach to assess
- evaluation criteria
what are the ABC’s of assessment for facial trauma?
A = airway
B = breathing
C = consciousness (aka mental status)
why do you need to manage significant bleeding in the face?
- to better assess all structures (for better visibility)
how can you check the nose and ears for CSF?
- halo test with a gauze wad (in the nose or ears, wherever there is bloody drainage)
what is the top-down approach to assess facial injuries?
- look for facial asymmetry
- forehead and orbits
- maxilla and nose
- cheekbones (zygoma)
- oral cavity and mandible
what are the evaluation criteria for facial injuries?
- asymmetry
- bony steps
- bony mobility
- bruising
what is the cause of a forehead fracture?
- blunt trauma
- fairly resistant to fractures
- superior portion of the weaker orbital structures reside here
what are the signs of a forehead fracture?
- severe headache and nausea
- possible defect on palpation
- blood in ear, ear canal, and nose
- possible ecchymosis around eyes or behind ear
- halo sign may be seen
what is the cause of an orbital fracture?
- direct trauma to the eyeball
what are the signs of an orbital fracture?
- possible displacement of the eye (enophthalmos)
- diplopia
- restricted upward gaze
- downward displacement of the eye
- soft-tissue swelling and hemorrhaging
- subconjunctival hemorrhaging (red in the white of the eye)
- periorbital ecchymosis
- unilateral epistaxis (nosebleed on the injured side because of sinuses)
- numbness of the cheek, side of nose, upper lip or ipsilateral teeth (because of injury to the infraorbital nerve)
how do you care for an orbital fracture?
- ice
- no blowing nose
- no Valsalva maneuver (keep head upright and limit movement)
- *the risk of infection is high
- x-ray/CT to confirm fracture
- treated surgically or will resolve spontaneously
