Chapter 63

Head Injuries

• TBI– Traumatic Brain Injury

General Information• Involves injury to

– Scalp– Skull– Brain

• High Risk Groups– Male vs. Female?

• Male

– Age?• < 30yrs

– #1 Variable• Alcohol

Pathophysiology• Damage • Swelling • ICP • Displacement • Blood flow • O2 • Ischemia • Infarction• Deathmosis

Scalp Injuries

• Clinical manifestation– Bleeding

• Profusely!

Scalp Injuries

• Abrasion:– Wound caused by • Rubbing or • Scrapping the skin

Scalp Injuries

• Contusion:– Injury to the tissue

without…• Breaking the skin

Scalp Injuries

• Laceration– The act of…• Tearing

Scalp Injuries

• Avulsion– The…– Tearing away of a

structure or part

Scalp Injuries

• Complication– Infection– Clean– Use procaine/Lidocaine– Suture

Skull Injuries / Fractures

• Classifications– Linear

• Line

– Comminuted• A bone is shattered into

many pieces

– Depressed• Comminuted fx in which

broken bones are displaced inward

Skull Injuries / Fractures

• Classifications– Basilar:

• Breaks in boned at the base of the skull

– Open:• The dura is torn

– Closed• The dura is intact

Skull Injuries / Fractures

• Clinical manifestations– Local injury– Pain

• Persistent

– Swelling?• Sometimes

Skull Injuries / Fractures

• Clinical Manifestations– Halo Sign

• Description– Blood stain surrounded

by a yellowish ring

• Indication– CSF leak

Skull Injuries / Fractures

• Clinical Manifestations– Basilar

• Hemorrhage from – Nose– Pharynx– Ears

• Blood under the – Conjunctiva

• Battle’s sign• CSF otorrhea• CSF rhinorrhea

Skull Injuries / Fractures

• Diagnostic Tests– X-ray– CT– MRI– Angiography

• Hematoma

Skull Injuries / Fractures

• Medical Management– Non-depressed skull

fractures• Usually do no require

– Surgical treatment

• Do require close– Observation

Skull Injuries / Fractures

• Medical Management– Depressed skull fractures

• May require surgery • Surgical debridement• Antibiotics

Quote from text

“After the skull fragments are elevated, the area is debrided. Large defects can be repaired immediately with bone or artificial grafts; if significant cerebral edema is present, repair of the defect can be delayed for 3-6 months.”

Skull Injuries / Fractures• Medical Management

– Basilar skull fractures• Usually open or closed?

– OPEN

• Keep nose and ears– Clean

• Sterile cotton pad/ball– Loosely inserted

• Instruct pt not to – Blow nose

• HOB:– Up

• I-ICP protocol

Question??????

• You notice the sheet under a patients head is red with blood, but the stain has a yellowish ring around it. What would be a priority nursing actions?– Notify MD– Infection control!!– Act first -- document last

Question????

• How do you prevent infections in a patient with a head wound?– Clean– Inject antibiotic

• A patient enters the ER following a MVA where he was thrown from the car. He has a major head wound. His vital signs show very low blood pressure. What does this indicate?– Hypovolemia– More than just head injury

Question????

• An open skull fracture means what? What nursing measures do you implement? What are the risks? – Dura mater is torn– CSF leakage possible– Increase risk of infection

Question?????

• What kind of an injury produces hemorrhaging from the nose, pharynx and ears?– Basil skull fracture

Question????

• Do you give morphine for pain to a patient with head injury? Why or why not?– NO– Interferes with accurate neuro assessment

Brain Injury

• Concussion– Pathophysiology

• Temporary loss of neurologic function with no apparent

• Structural damage

– Closed / open?• Closed

– Duration of unconsciousness?• Seconds to few minutes

Brain Injury

• Concussion– S&S

• LOC• Memory loss• Headache

Brain Injury

• Concussion– Emergency S&S

• Difficulty awakening• Dysphasia• Confusion• Severe H/A• Vomiting• Weak on one side

Brain Injury

• Concussion– Diagnostic tests

• CT• MRI• X-ray• Neuro checks

Brain Injury

• Concussion– Medical treatment

• Analgesics– Mild

• Observe for post-concussion syndrome

• Return to ER if you see any of the emergency S&S

Brain Injury

• Concussion– Gerontologic

Considerations• Will recover more • Slowly with • More complications

Brain Injury: Contusion• Pathophysiology– The brain is bruised,

with possible surface hemorrhage

– Duration of unconsciousness:• More than concussion

– Potential of infarction & necrosis

Brain Injury: Contusion

• Contracoup/Contralateral Phenomenon– Damage to brain occurs

opposite to impact

Brain Injury: Contusion• Symptoms: Similar to shock

– Activity• Motionless

– Pulse• Faint

– Respirations• Shallow

– Skin• Cool & pale

– Bowel & bladder • Evacuation

– BP•

– Temp•

Question????

• Is a concussion an open or closed head injury?– Closed

• Is a contusion an open or closed head injury?– Closed

Brain Injury: Intracranial Hemorrhage

• A collection of blood that develops within the cranial vault

• Small & fast vs. large & slow

• Symptoms are frequently delayed

Question????

• Which is more fatal, a small hematoma that develops rapidly or a large hematoma that develops slowly?– Fast = Fatal

Brain Injury: Intracranial Hemorrhage

• Epidural hematoma / Extradural hematoma– Blood collects

• Btw the skull & dura

– Usually due to• Fx of skull

– Type of blood vessel• Arterial bleed

– Onset of symptoms• Rapid

Brain Injury: Epidural hematoma

• Clinical manifestations– Time of injury

• Momentary loss of consciousness

– Lucid interval• Compensation

– Sudden S&S of compression

Brain Injury: Epidural hematoma

• Management– Extreme emergency– Burr Holes

Brain Injury: Subdural Hematoma

• Collection of blood– Btw dura & brain

• Usually due to– Trauma– Venous blood

Brain Injury: Intracerebral Hemorrhage & Hematoma

• Bleeding into– Brain

• Usually due to– Aneurysm– Missile injuries

Management of Brain Injuries

• Treatment of I-ICP• Assume spinal injury• Baseline neurological

assessment• Brain Death

Question?

SCI: Complications & Interventions

Spinal Shock• A sudden depression of reflex activity in the

spinal cord below the level of injury due to the loss of autonomic nervous system function

SCI: Complications & Interventions Spinal Shock

S&S• Areflexia• Vasodilitations – ______tension

• Hypotension

• Bowel distention• Treatment– bulk– fluid– Stool softener– Disimpaction

SCI: Complications & InterventionsThermal Regulation

• Not perspire• Fever?

SCI: Complications & InterventionsAutonomic Hyperflexia /dysreflexia

• Injury impairs normal equilibrium between the sympathetic and parasympathetic system– Vasoconstriction below the level of injury– Vasodilation above the level of injury

• Common cause– Noxious Stimuli– Below level of injury

SCI: Complications & InterventionsAutonomic Hyperflexia /dysreflexia

S&S• Above injury– Vasodilation– Pounding H/A– Profuse diaphoresis– Nasal congestion

• Bradycardia• Hypertension– > 300 mmHg systolic

SCI: Complications & InterventionsAutonomic Hyperflexia /dysreflexia

Treatment• Monitor BP• How BP fast?– HOB

• Find & remove noxious stimuli

• If med with apresoline – crash
