Lecture 17: Head and Face injuries Flashcards
cause of injuries for facial lacerations
- may be a penetrating (sharp object) or blunt trauma causing direct or indirect compressive force
signs of facial lacerations
- pain
- substantial bleeding
care for facial lacerations
- facial lacerations should be cleaned with sterile saline and assessed for the presence of debris or damage to underlying structures.
- apply pressure to control the bleeding
- rule out skull/ brain traumas
- referral to a physician may be necessary for stitches
cause of injury for scalp injuries
- highly vascular area
- blunt trauma or penetrating trauma tends to be the cause
- can occur in conjunction with serious head trauma
care for scalp injuries:
- clean with antispetic soap and water (remove debris)
- cut away hair if necessary to expose area
- apply firm pressure to reduce bleeding
- wounds larger than 1/2 inch in length should be referred to hospital
- smaller wounds can be covered with protective covering and gauze (use extra adherent)
(can use pressure and ice to help stop the pain and bleeding)
signs of scalp injuries
- athlete complains of blow to the head
- bleeding is often extensive and difficult to pinpoint exact site
(can be difficult to pin point because the athlete has so much hair)
how to know when to send someone for stitches?
- tissue adhesive generally is recommended for closure of simple lacerations less than 4 cm in length that are not at points of high skin tension
- for wounds over 4cm in length or at points of high skin tension
- if it is through all skin layers and/or showing exposed fat, tendons, bones, or vessels
- place a non-medicated gauze pad over the lesion if patient is to be sent for sutures
- within 8-12 hours max
what are other options for instead of stitches?
1: steri-strips
2: butterfly bandage
what are the steps for assessing cuts?
1: identify the area
2: get the bleeding to stop
3: then you can assessing for fractures
the dura mater is on the –
the subarachnoid space is on the –
1: outside
2: inside
head injuries
- occur as a result of direct blow causing compressive force, tensile (negative pressure force) or shearing.
- CSF
what does CSF do?
- it acts to convert focal force into compressive stress that is dissipated over the brains full surface
- has minimal impact on shearing force, especially when combined with rotations
what are signs of head injuries?
1: halo signs
2: battle signs
3: raccoon eyes
battle sign
- when there is per auricular ecchymosis (bruising around the ear)
- late findings, usually 24-48 hours!
racoon eyes
- periorbital ecchymosis
- bleeding under the skin around the eyes
- also late findings 24-48 hours
halo sign
- clear drainage that separates from bloody drainage suggests the presence of cerebrospinal fluid
pupil reactions and possible causes
1: pupils equal and reactive to light
- normal
2: equal but dilated/unresponsive
- cardiac arrest, CNS injury
3: equal but constricted/unresponsive
- CNS injury or disease
4: unequal, one dilated/unresponsive
- cerebrovascular accident (CVA)
- head injury
- direct trauma to the eye
epidural hematoma
cause of injury
- blow to head or a skull fracture which tears meningeal arteries
- blood accumulation and creation of hematoma and pressure occur rapidly (minutes to hours)
- blood accumulates on the outside.
- slowly, have the tear, then bruise forming, then it starts to put pressure on the brain
signs of epidural hematoma
- may or may not have brief loss of consciousness followed by a period of lucidity. During this period they may not display clear signs and symptoms of a serious head injury
- gradual progression of signs and symptoms
- severe head pain, dizziness, nausea, dilation of one pupil (anisocoria), occurring on same side as injury, deterioration of consciousness, depression of pulse and respiration, and convulsion
they basically get hit, feel fine, then you start to see a gradual decline over the course of the next couple of hours
care for epidural hematoma
- requires urgent neurosurgical care
- must relieve pressure to avoid disability or death
subdural hematoma
- result of acceleration/deceleration forces that tear vessels that bridge dura matter and brain
- venous bleeding (simple hematoma may result in little to no damage to cerebellum while more complicated bleed can damage the cortex)
- this happens inside the dura
signs of subdural hematoma
- athlete may experience loss of consciousness in seconds to minutes
- pupillary asymmetry
- signs of headache, dizziness, nausea or sleepiness if not unconscious (all immediate sings)
care for subdural hematoma
- immediate emergency medical attention
- CT or MRI is necessary to determine extent of injury
recognition and management of specific facial injuries
1: assess:
- mental status (conscious or unconscious, if un conscious send them to hospital right away)
- airway and breathing
2: manage significant bleeding
- can better assess all structures
3: check nose and eats for CSF
4: take a top-down approach to assess
- get an idea of facial asymmetry ASAP these injuries will swell quickly
- forehead and orbits
- maxilla and nose
- cheekbones (zygoma)
- oral cavity and mandible
5: evaluation criteria
- symptoms
- asymmetry, bony steps, bruising and mobility
cause of injury for forehead fractures
- most common cause is blunt trauma
- usually fairly resistant to fractures
- most superior portions of the weaker orbital structures reside within the bounds of the forehead
signs of injury for forehead fractures
- severe headache and nausea
- palpation may reveal defect in skill
- may be blood in the middle ear, ear canal, nose, ecchymosis around the eyes (raccoon eyes) or behind the ear (battle signs)
- cerebrospinal fluid may also appear in ear and nose (halo sign seen on gauze)
orbital fracture cause of injury
- direct trauma to the eyeball
orbital fracture signs of injury
- possible posterior displacement of the eye
- diplopia (double vision, immediate referral to the hospital)
- restricted upward gaze
- downward displacement of the eye
- soft-tissue swelling and hemorrhaging
- subconjunctival hemorrhaging
- periorbital ecchymosis (raccoon eyes)
- unilateral epistaxis
- numbness
orbital fracture care
- ice, no blowing nose and valsalva maneuver (risk of infection (due to proximity of maxillary sinus and bacteria)
- x-ray/CT will be necessary to confirm fracture
- treated surgically or allow to resolve spontaneously
