Neurology Management of Patients With Neurologic Trauma 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 • h ICP • Displacement • i Blood flow • i 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 • i • Temp • i
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? • What type of hematoma’s are usually associated with arterial bleeds? • Epidural • What type of hematoma’s are usually associated with venous bleeds? • Subdural
Spinal Cord Injury • Etiology • Male vs Female • Male • Variable • MVA • Age • < 30 yrs • Most frequently involved area • C-5,6,7 • T12-L1
Spinal Cord Injury • Pathophysiology • Transient concussion • Contusion • Laceration • Compression • Complete transection
Spinal Cord Injury • Clinical manifestations • Incomplete spinal cord lesions • Neurologic Level • Lowest level where sensory & motor function are normal
Question????? • Is it possible to break your back (vertebrae) without damaging your spinal cord? • Yes
Spinal Cord Injury • Below neurologic level • Loss of sensory and motor function • Loss of B&B control • Loss of sweating • i in BP
