OVERVIEWOVERVIEW

• Anatomy of skull and brain• Pathophysiology of head injury• Review of specific head injuries• Assessment of head trauma• Management of head trauma

HEAD INJURYHEAD INJURY

• Cause of death in 25% of trauma patients• Cause of death in 50% of MVCs• Significant long term disability• Prompt recognition and treatment can

improve outcome• All patients with head or facial trauma have

c-spine injury until proven otherwise

ANATOMYANATOMY

BRAIN INJURYBRAIN INJURY

• Brain injury results from:– Direct injury to brain tissue– External forces applied to

outside of skull transmitted to the brain

– Movement of brain inside skull

COUP CONTRACOUPCOUP CONTRACOUP

• “4 collision” concept– Auto strikes tree

– Head strikes windshield

– Brain strikes inside of frontal skull

– Brain rebounds and hits inside of occipital skull

PRIMARY vs. SECONDARY

BRAIN INJURY

PRIMARY vs. SECONDARY

BRAIN INJURY

• Primary injury is immediate from bruising or penetrating objects

• Secondary injury is from hypoxia or perfusion of the brain– Caused by swelling, hypoxia, or

hypotension– May be prevented by good patient care– Hyperventilation decreases perfusion of the

brain tissue– Protect airway, give oxygen, maintain BP

• Very vascular• Bleed briskly• Most scalp bleeding can

be controlled with direct pressure

ASSESSMENT RAPID TRAUMA SURVEY

ASSESSMENT RAPID TRAUMA SURVEY

• Note LOC (AVPU), secure airway and protect c-spine

• Assess breathing– Do not allow the patient to become hypoxic

• Assess circulation– Control major bleeding– Prevent hypotension

• Transport decision and interventions• Do brief neuro & GCS if altered LOC

ASSESSMENT DETAILED EXAM

ASSESSMENT DETAILED EXAM

• Vital signs• SAMPLE history• Head-to-toe exam, including neurological

and GCS• Further bandaging and splinting• Continuous observation

MANAGEMENT OF THE HEAD TRAUMA PATIENTMANAGEMENT OF THE

HEAD TRAUMA PATIENT

• Stabilize the c-spine• Secure and maintain the airway• Ventilate at about 15 breaths/min.• Prevent hypoxia• Hyperventilate only patients with the

herniation syndrome– Coma, BP, Respiration, bradycardia

AIRWAY CONTROL CANNOT BE OVEREMPHASIZED

AIRWAY CONTROL CANNOT BE OVEREMPHASIZED

MANAGEMENT MANAGEMENT

• Record baseline exam– Neuro, GCS & pupils– Vital signs

• Maintain good circulation– BP 110-120 systolic

• Continually monitor and record observations

• Prompt transport

PITFALLS & PROBLEMSPITFALLS & PROBLEMS

• Anticipate c-spine injuries• Protect the airway - prevent

aspiration• Prevent hypoxia• Prevent shock

– IV fluids and PASG are OK

PITFALLS & PROBLEMS PITFALLS & PROBLEMS

• Be prepared for seizures• Rapidly deteriorating condition

requires rapid hospital treatment• Assess for other causes of altered

LOC– Hypoglycemia– Alcohol– Drugs

SUMMARYSUMMARY

• Follow patient assessment• Protect c-spine, airway, and circulation• Record frequent vital signs, neuro, pupils,

and GCS• Prompt transport
