    • •Break in basal portions of the frontal, ethmoid, sphenoid, temporal or occipital bones
    • •Battle sign:
    • –Postauricular bleed in mastoid sinus
    • •Raccoon eyes:
    • –Bleed into frontal sinuses
    • •May have CSF leak from nose or ears
    • –Antibiotics used prophylactically
    • •Associated with cranial nerve injuries
  103. What are Complications of Head Injuries?
    • Hemorrhage
    • Infection
    • –Watch for post traumatic meningitis: fever & ↑ drowsy w/basilar skull fracture
    • Edema
    • –From tissue trauma
    • Tentorial herniation
  104. What is Epidural Hemorrhage?
    • •Blood accumulates between dura & skull
    • •Bleeding usually arterial: rapid brain compression
    • •Classic: momentary unconsciousness—normal—lethargy/coma
    • –Seldom in peds!
    • •May be symptom free for longer than 48 hrs
    • •Uncommon <4 yoa
  105. What is Subdural Hemorrhage?
    • •Bleeding between dura & cerebrum
    • •Cortical vein ruptures—spreads slowly, thinly & widely
    • Common in infants:
    • –Birth trauma, falls, violent shaking
    • –Peak: 6 months
    • •May have high mortality & poor prognosis
    • –May have developmental retardation & FTT
  106. What is Posttraumatic Syndrome?
    • •From structural complications from the head injury
    • •Minutes to an hour after the injury
    • •Last several days to several months
    • •Post traumatic seizures may occur within 2 yrs of injury

    • Infants
    • –Pallor
    • –Sweating
    • –Irritability
    • –Sleepiness

    • –Most common brain tumors in children

    •S&S depend on anatomic location & size & child’s age
