TRAUMATIC HEAD AND SPINAL CORD INJURY

Deformation

Acceleration-deceleration

Rotation

MECHANISM OF INJURY

1.DIRECT HEAD INJURY

CLASSIFICATION OF HEAD INJURY

2. INDIRECT HEAD INJURY

OPEN HEAD INJURY

CLOSED HEAD INJURY

COUP AND COUNTERCOUP INJURY

1.SCALP INJURY

ABRASIONS

CONTUSIONS

LACERATION

CLASSIFICATION BASED ON THE LOCATION

2.SKULL FRACTURE

a. Linear fracture

b. Depressed skull fracture

c. Diastatic skull fracture

d. Basilar skull fracture

e. Cranial burst skull fracture

f. Compound skull fractures

2. MENINGEAL INJURIES

1.CONCUSSION

Typical signs.

• Altered level of consciousness

• Amnesia

• headache

2.CONTUSION

Typical signs

• Hemorrhage

• Infarction

• Necrosis

• Edema

• Seizure

• Increased I.C.P

3.CEREBRAL INJURIES

SPINAL CORD INJURY

1. Hyper flexion

2. Hyperextension

CLASSIFICATION OF SPINAL CORD INJURY

3. Compression injury

4.Rotational injuries

5.Penetrating injury

• COMPLETE INJURY

• INCOMPLETE INJURY

CLASSIFICATION BY DEGREE OF INJURY

1.Central cord syndrome

• Motor deficits in the upper extremities

• Less impairment in leg movements

• Sensory loss below the site of injury

• Loss of bladder control may occur

INCOMPLETE INJURY

2. Anterior cord syndromeLoss of perception of pain, temperature and motor

function is noted below the level of the lesion

3. Brown sequard syndrome

4. Conus medullaris and Cauda equina syndrome

• Lower extremity dysfunction

• Loss of bladder and anal sphincter

• function

• Male sexual dysfunction

• Loss of achilles reflex

Road traffic accident

Fall from higher place

Athletic accidents

Blast injuries

Anti coagulant and anti platelet medications

Occupational accidents

penetration

ETIOLOGICAL FACTORS

Brain suffers traumatic injury

Brain swelling or bleeding increase intra cranial volume

Intra cranial pressure increases

Pressure on blood vessels with in the brain increases

Decreased blood flow to the brain

Cerebral hypoxia and ischemia occur

Herniation of the brain

Brain death

PATHOPHYSIOLIOGY OF BRAIN TRAUMA

Hemorrhage

RBC and platelet break down of RBC

Aggregation

Free radical formation

Release of nor epinephrine

Serotonine,dopamine secondary injury

Vasoconstriction spinal edema, tissue hypoxia

Thrombosis formation

SC blood flow

PATHOPHYSIOLOGY OF SPINAL CORD INJURY

HEAD TRAUMA

Altered level of consciousness

Confusion

Pupillary abnormalities

Altered or absent gag and corneal reflex

Sudden onset of neurological onset

Changes in vital signs

Spasticity

Vertigo

Seizures

Ottorhoea

Rhinorrhoea

Slurred speech

CLINICAL MANIFESTATIONS

SPINAL CORD INJURY

Spinal shock and neurogenic shock

Respiratory distress

Bradycardia

Poikilothermism

Low blood pressure

Loss of bowel or bladder control

Loss of sensation, including the ability to feel heat, cold and touch

Difficulty with balance and walking

Loss of movement

Spinal edema

CERVICAL INJURIES

C-1/C-2 levels will often result in loss of breathing

C3 vertebrae and above : Typically results in loss of diaphragm function

C4 : Results in significant loss of function at the biceps and shoulders.

C5 : Results in potential loss of function at the biceps and shoulders, and complete loss of function at the wrists and hands.

C6 : Results in limited wrist control, and complete loss of hand function

C7 and T1 : Results in lack of dexterity in the hands and fingers, but allows for limited use of arms

THORACIC INJURIES

T1 to T8 : Results in the inability to control the abdominal muscles

T9 to T12 : Results in partial loss of trunk and abdominal muscle control.

LUMBOSACRAL INJURIES

Dysfunction of the bowel and bladder

Sexual dysfunction

Hisory collection

Physical examination

Neurological examination

Ct and m.R.I

Pet scan

Nerve conduction studies

Transcranial doppler studies

X ray

Blood investigation

DIAGNOSTIC FINDINGS

AMERICAN SPINAL INJURY ASSOCIATION SCALE

‘ASIA’ SCALE

A. Complete Complete loss of sensory and motor function

b. incomplete Sensory function is preserved but no motor function

c. incomplete Motor function is preserved and muscle grade more than 3

d. incomplete Motor function is preserved and muscle grade more than 3

e. normal Motor and sensory function are normal

2/2/2 rule

1. Patient die in 2 mins from airway and breathing compromise and hypovolemic shock

2. Patient die in 2 hrs from hypovolemic shock

3. Patient die in 2 weeks from septic shock

MANAGEMENT

Management of trauma patient can be divided in to 2 phase

• Primary phase

• Secondary phase

MANGEMENT

A - AIRWAY

B- BREATHING’

C- CIRCULATION

D- DISABILITY
