Head and Neck

Question 1

Altered Head Injured Patient. Start with trauma primary survey

Answer 1

ABCDE
D=Disability, caused by the injury?
E=Exposure, take the pts cloths off.

Question 2

Pupil eval
Miosis?
one pupil larger then other?
Mydirasis?

Answer 2

Miosis=OPIATES. PONTINE LESION

One pupil bigger then the other?=LEFT HEMATOMA- HERNIATION OR OCULAR GLOBE TRAUMA, commonly stroke, brain or optic tumor, brain aneurysm, MS.

Mydriasis=INCREASED ICP WITH POOR CEREBRAL PERFUSION, DRUG EFFECT, BILATERAL HERNIATION, SEVERE HYPOXIA

Question 3

Evaluation and Management of the Head injured Patient

Answer 3

The Glasgow Coma Scale
Standardized evaluation of neurological status
Reproducible - can be performed by multiple examiners at different levels of care
Predictive of morbidity/mortality

Question 4

Glasgow Coma Scale

Eye opening

Answer 4

4: Spontaneous eye opening.
3: Eye opening in response to speech – that is, any speech or shout.
2: Eye opening in response to pain.
1: No eye opening.

Question 5

GCS continued

Best Verbal Response

Answer 5

5: Oriented - patient knows who and where they are, and why, and the year, season and month.
4: Confused conversation - patient responds in conversational manner, with some disorientation and confusion.
3: Inappropriate speech - random or exclamatory speech, with no conversational exchange.
2: Incomprehensible speech - no words uttered, only moaning.
1: No verbal response.

Question 6

GCS continued

Best Motor Response

Answer 6

6: Carrying out request (‘obeying command’) - patient does simple things you ask.
5: Localising response to pain.
4: Withdrawal to pain - pulls limb away from painful stimulus.
3: Flexor response to pain - pressure on nail bed causes abnormal flexion of limbs (decorticate posture).
2: Extensor posturing to pain - stimulus causes limb extension (decerebrate posture).
1: No response to pain.

Question 7

GCS Interpretation

Answer 7

A.V.P.U.
Alert, or responsive to 
Verbal stimuli, or to
Painfull stimuli, or 
Unresponsive

Answer 8

A -> Allergies
M -> Medications (especiallyanticoagulants/anti-platelets)
P -> Past medical history
L -> Last meal (especially if surgery is indicated emergently)
E -> Events (what happened just before..?)
VITALS SIGNS ARE VITAL!!!!

Question 9

Epidural Hematoma=Definition, sx’s

Answer 9

Transient loss of consciousness; lucent interval
Laceration of dural vessels from skull fracture (91%), usually the middle meningeal artery
3rd nerve palsy (sign of cerebral herniation)
Somnolence 24-96 hrs after accident

Question 10

Epidural Hematoma=Etiology

Answer 10

Hematoma expands
Increased ICP, decreased CBF
Herniation, ipsilateral CN-3 dysfunction and contralateral paralysis or posturing

Question 11

Subdural Hematoma

Answer 11

Incidence: 5% of head trauma patients
Age: infants and elderly (large subarachnoid space with freedom to move)
Cause: damage to subdural veins (“bridging veins”)
Acute Subdural Hematoma:
Manifests hours after injury
Hyperdense (<1 week); isodense (1-3 weeks); hypodense (3-4 weeks)
Underlying brain injury (50%)
Worse long term prognosis than epidural hematoma

Question 12

Subdural Hematoma=Etiology

Answer 12

May be acute, like epidural hematoma
May have delayed course, days to weeks
Increased ICP, edema, herniation
ETOH increases cerebral edema by increasing the permeability of the blood brain barrier

Question 13

Subdural Hematoma=different types

Answer 13

Chronic Subdural Hematoma:
Following minor injury, rarely parenchymal injury
Convex configuration

Interhemispheric Subdural Hematoma:
Usually posterior
Most common acute finding in child abuse
(whiplash injury)

Question 14

Sub-Arachnoid Hemorrhage

Answer 14

Bleeding from small vessels at site of coup or contrecoup injury
Bleeding under arachnoid, spreads in CSF
Vasoactive substances in blood contribute to ischemia and altered level of consciousness

Question 15

Sub-Arachnoid Hemorrhage=etiology

Answer 15

Often occurring directly beneath an external injury
Can also occur as a contrecoup injury
Direct rupture of intrinsic cerebral vessels.

Separation of suture between temporal and occipital bones
May involve orbits or sphenoid bone, or fracture near foramen magnum

Question 20

Basal Skull Fracture

Answer 20

Damage to Cranial nerves III, VII or 	
CSF otorrhea, CSF rhinorrhea 				(danger of meningitis!)		
Battle’s sign
Racoon eyes
Hematotympanum

Question 21

Treatment of the seriously head injured patient

Answer 21

Seizure prevention: IV Phenytoin
Prevent fever
Control bleeding, transfuse to HCT>30
Antibiotics for penetrating injury or basal skull fracture
Early neurosurgical consultation: ventriculostomy, craniotomy

Question 22

Treatment of the seriously head injured patient

Answer 22

Treat hypotension, resucitate to MAP>90 (SBP 120-140 with NS. Pressors as needed. N.B. isolated head injury is unlikely to be hypotensive on initial presentation, so look for other injuries!
Control excessive hypertension. Labetolol to reduce BP 20-30%
Treat hypoxia, intubate and ventilate (increased CO2 dilates vessels and lowers cpp)
Sedate if needed (not ketamine)

Question 23

Treatment of the seriously head injured patient

Answer 23

Treat increased ICP (target <20, cpp70- 80)‏
Raise head of bed to 30 degrees
IV mannitol boluses once euvolemic
(serum osmolality 280-300)‏
Hyperventilate PCO2 to 26-30? Consider only if other measures ineffective
Steroids not proven to have benefit in head trauma

Question 24
