Severe Head Injury = spinal cord injury Unconscious Patient 7 Management of the trauma victim To prevent more cord damage Movement Metabolic To prevent complications 8 Accident scene History - of accident - of pain, etc. - of sensation - of movement 9 3
Accident scene (2) Examination - Sensation - Motor power - (Reflexes) - Pulse 10 Sacral neurologic examination Sensation Voluntary anal contraction Sacral reflexes 11 Light touch 2 - Normal 1 - Decreased 0 - Nil Pin prick Hyperaesthesia or other abnormal sensations 12 4

Transport Maintain neutral midline position and use spine board or ambulance trolley 25 Approach Resuscitation Treat multi-trauma Ensure skeletal stability Manage implications of spinal damage 26 27 9
Primary hospital Nasogastric tube Intravenous/Central line Indwelling catheter Temperature control Cervical collar Respiratory management 28 Bladder management Prevent overdistension Fluid balance 29 Intravenous access Fluid resuscitation Administration of drugs Administration of fluids 30 10
Spinal shock A period of hypoactivity of the spinal cord below the level of injury lasting for hours to weeks after spinal cord injury 31 Spinal shock (2) Features Loss of reflexes Flaccid paralysis of striated muscles Flaccid paralysis of bladder Paralytic ileus Loss of sympathetic tone in high paraplegia and quadriplegia 32 Respiratory complications in spinal shock Flaccid paralysis of intercostal muscles Flaccid paralysis of abdominal muscles 33 11
Inspiration Normal Quadriplegia e.g., C4 in spinal shock 1. Diaphragm descends 1. Diaphragm descends 2. Chest expands 2. Intercostals drawn in 3. Air drawn into lungs 3. Small amount of air drawn in 34 Respiratory complications Paralytic ileus Acute gastric dilatation Haemo +/- haemopneumothorax Lung contusion 35 Respiratory past history Smoking Asthma Other respiratory conditions such as bronchiectasis 36 12
Cervical and mid thoracic cord lesions Admit to respiratory ICU Physiotherapy Antibiotics Early intubation Ventilation Tracheostomy 37 Paralytic ileus Usually lasts 0-10 days Need nasogastric tube to prevent aspiration of gastric contents into lungs and acute dilatation of stomach 38 Acute abdominal trauma Non SCI Acute SCI Guarding/Rigidity Flaccid paralysis Paralytic ileus Paralytic ileus Pain No pain Beware if relative tachycardia 39 Diagnostic investigation Abdominal CT Peritoneal lavage 13
Cord lesion T6 and above Loss of sympathetic tone Vasodilation Hypotension Poikilothermia Unopposed vagal tone on heart brachycardia Leads to cardiovascular instability 40 Cord lesion T6 and above Treatment of severe bradycardia Atropine 300 g 2 hourly to 3mg/day Theophylline 80mg tds Cardiac pacing 41 Radiology CT MRI Adequate plain films Long AP LAT (Including upper T1) Open mouth AP to show C1, C2 Obliques cervical 42 14
CT 43 MRI 44 Verterbral column stabilisation Achieve normal alignment Treatment does not improve neurology Options Closed reduction + traction Closed reduction + external function Closed reduction + internal function Reduces down time by 5-7 weeks 45 15
DVT prophylaxis Low molecular weight Heparin; e.g., Clexane 40mg S/C daily Calf stimulators 46 Prophylaxis against G.I.T. ulceration H2 antagonist + antacid 47 Skin care 48 16
