Cranio-Cerebral TraumaRe-written by: Daniel HabashiSeminar by: Dr. Jezewski (Asshole)
History
•5000 years ago•Edwin Smith Papyrus (1700 B.C.)•Description of 48 patient neurosurgically
treated in Ancient Egypt. The first time the word “brain” was used.
Neurosurgery Made By Monks
•Some more history and pictures. Nothing important for a test obviously.
Main Causes Of Cranio-Cerebral Trauma•Car accidents 50%•Falls 30%•Criminal 7%•Sport 7%
GCS – Glasgow Coma ScalePoints Eye response Verbal
responseMotor response
6 - - Obeys
5 - Oriented Localizes pain
4 Spontaneously Disoriented Flexion withdrawal
3 To verbal command
Inappropriate words
Flexion abnormal
2 To pain Incomprehensible sounds

GCS
•GCS describes patients clinical status after head trauma and influences the speed of diagnostic and therapeutic procedures
•GCS < 8 = serious status
Neurological Examination
•Reflex•Flexion / Extension•Anisocoria (ipsilateral not contralateral)
•The most important are the dynamics of symptoms
What To Do With A Head Trauma Patient?• 1. head and trunk lifting 30 degrees• 2. Analgosedation (Dormicum + MF / Fentanyl)• 3. Osmotherapy (Mannitol) > 320mOsm/L• 4. Anticonvulsant protection• 5. Optimal ventilation parameters
▫ pO2 100mm Hg, pCO2 30-35mmHg• 6. Fighting against hypovolemic shock
▫ MAP > 90 mmHg▫ MAP < 90mmHg give Fluids: crystaloids, coloids, vasopressors
• 7. Neurological Examination• 8. ICP control
▫ ICP < 20-25mmHg▫ CPP> 60-70 mmHg
Diagnostic Procedures
•1. Head CT•2. Vertebral CT•3. Polytrauma CT•4. Chest X-Ray•5. Abdominal USG
Brain Contusion
•Structural in brain tissue mainly on the surface after trauma (this makes no sense grammatically but that’s what’s written)
•Pathomechanism:▫Acceleration / deceleration phenomenon in
head trauma▫Mechanism contr coup(?)

Subdural Hematoma
•Venous Origin (Bridge Veins)
•Acute▫(1st 24 hours after trauma)▫More typical for younger people
•Sub-acute▫(2-14 days after trauma)
•Chronic▫(few weeks even months or years after
trauma)
Subdural Hematoma – continued•The veins go from the surface of the brain
to the dura, and when they break there’s bleeding and collection of blood creating a hematoma in this space.
•Venous bleeding is different from arterial▫Slower – and that’s why we have acute,
sub-acute and chronic
Epidural Hematoma
•Always arterial in origin•In 90% of cases coexists with a skull
fracture•Acute is the most frequent type
•It’s a dynamic hematoma with fast developing symptoms (ACUTE).
•Arterial in origin because of the meningeal arteries
•Surgical treatment due to CT confirmation
•Subdural and epidural haematoma Urgent Surgery!!!
•Subdural or epidural hematoma evacuation
Anterior fossa fracture and nasal liquorrhea •Typical fractures in non-airbag deployed
car accidents•Very vey dangerous because the ethmoid,
glenoid(?) and frontal sinus fractures leads to CSF leakage from the nose and ear (temporal bone fracture)
•Can lead to bacterial infections and meningitis

Osmotherapy• Mannitol 20% 4 x 200 – 250ml• Glicerol 100% 4 x 200ml• Furosemide 60mg/d• Steroids?????• Decadron 0.5 – 1mg/kg 1 Bolus• Golden hour – then 4 x 8 mg• Anticonvulsants – diazepam, phenytoin
• Normothermia• Barbitural coma• ICP monitoring
