ED documentation and referral

  • ED Trauma team leader ensures an ASIA chart is completed.
  • ED Trauma team leader confirms SCI and refers to Neurosurgical Registrar.

Admission pathways

All patients with a traumatic spinal cord injury should be admitted to a critical care environment. Isolated SCI patients should be admitted under the care of Neurosurgery, or transferred to the local MTC or ICU (Intensive Care Unit) following advice from SIU (Spinal Injuries Unit) and Neurosurgeon.

Referral and transfer to spinal injuries unit (SIU)

The neurosurgical registrar refers to Spinal Injuries unit within 4 hours of diagnosis (Please refer to the Referral Form). An early joint management plan must be formulated and recorded in the notes within 12 hours Transfers to SIU do not usually occur direct from the ED (only at SIU discretion).

Patients accepted for transfer to SIU should be transferred within 24 hours of being stable and accepted for transfer Spinal stabilisation for patients with a spinal cord injury may be chosen to be undertaken at the SIU in Glasgow. See Spinal Injury Unit Transfer Checklist.

Management principles in ED/early ICU

Spinal Shock

Total flaccid paralysis of all skeletal muscle and loss of all spinal reflexes below the level of the lesion. It may last several hours to weeks. The return of the bulbospongiosus reflex denotes its end.

Neurogenic Shock

Body's response to sudden loss of sympathetic control in cervical and high thoracic lesions (above T6). Hypotension is from a lack of vasomotor control. Bradycardia from of an unopposed vagus nerve.

Airway

Intubation can precipitate severe bradycardia and cardiac arrest in cervical/high thoracic spinal cord injuries. Atropine 0.3mg / 0.6mg may be required.

Breathing

Patients with high cord lesions (C3/4/5) have a considerable risk of respiratory deterioration.

  • Monitor SaO2, blood gases and vital capacity
  • Use humidified oxygen
  • Early, regular, and frequent physiotherapy including assisted cough and incentive spirometry
  • Hourly turns to optimise V/Q mismatch
  • Elective ventilation may be needed
  • Secure airway if vital capacity <1L
  • Consider primary tracheostomy
  • Pre-oxygenate with 100% oxygen before and after suctioning as bradycardia and hypoxia can occur.

Circulation

  • Patients with acute spinal cord injury must be nursed flat.
  • Monitor BP usually via arterial line.
  • Maintain SBP >100mmHg. Initial MAP target 85mmHg. Consider maintaining these targets for 7 days.
  • Maintain urine output of >30mls per hour.
  • Administer IV fluids - DO NOT over-infuse. This may precipitate cardiac failure and pulmonary oedema.
  • Vasoconstrictors via a central line may be required to maintain a stable BP.
  • Use atropine 0.5-1.0mg or glycopyrrolate 200-600mcg IV for bradycardia <40bpm or instability.
  • Bradycardia usually resolves over a few days. Avoid pacemakers where possible.

Disability

  • Ensure ASIA chart (Appendix 6) is completed in full
  • Perform neurological examinations 2 hourly to identify and prevent any avoidable deterioration.

Other considerations

  • Do not give IV steroids
  • LMWH (Low Molecular Weight Heparin) VTE prophylaxis should be started by day 3 and TEDs/Flowtrons on admission.
  • Give regular PPI
  • Prescribe nebulised saline, salbutamol 2.5mg and ipratropium 250mcg 4 hourly in all high cord injuries.
  • Monitor for signs of alcohol withdrawal.

Skin

  • Heels should be supported clear of the bed with pillows.
  • Pressure relief and minimum 30 degrees side to side turning should occur every 2 hours from admission.

Bladder

  • All patients should be catheterised.
  • If priapism is present, initially manage with urethral catheterisation where possible. May require a suprapubic catheter.

Paralytic ileus

  • Nil-by-mouth.
  • NG tube in all patients (may precipitate bradycardia).
  • If abdomen is distending due to build up of gas, consider PR examination and decompression.
  • Commence NG nutrition as soon as feasible.

Bowel

  1. Daily insertion of a glycerin or bisacodyl suppository 15-30 minutes before rectal examination and evacuation if rectum full.
  2. If bowel sounds present, passing flatus or moving bowels then start in ALL patients:
    1. Senna 15mg alternate evenings
    2. Lactulose 15ml b.d.
    3. OR if unsuccessful consider Macrogol 1 sachet b.d.
    4. Bisacodyl 10mg alternate evenings

AND if T12 & above (reflex UMN bowel)

  1. Daily PR
  2. Daily anal digital stimulation to trigger reflex. CHECK digitally that emptying is complete

OR if L1 or below (flaccid LMN Bowel)

  1. daily PR
  2. daily manual evacuation of faeces (essential in these patients).

The use of a FLEXISEAL faecal collection device should take into consideration the risks and benefits to that patient. (E.g., Preservation of sacral skin integrity vs daily assessment of anal tone.)

Analgesia

  • Prescribe simple analgesia e.g., paracetamol
  • Opiates for fractures but caution in high cord injuries
  • Neuropathic analgesics e.g., gabapentin/amitriptyline.

Joint mobility

Daily passive limb movement, stretching and positioning with input from PT, OT and nurses from admission.

Principles of spinal immobilisation and clearing the spine

Assessing and imaging the thoracolumbar spine

Assessing and imaging the thoracolumbar spine

Thoracolumbar spine cleared radiologically***

  • Patients fit for general ward/discharge with a provisional, typed ‘normal’ CT report, may have TL spine cleared clinically by ST3 or equivalent. (This must be documented)
  • Normal CT with motor or sensory deficit, paresthesia, weakness, or numbness at rest or when mobilising should remain immobilised and be considered for MRI after discussion with radiologist/neurosurgeon.
  • Obtunded patients should be assessed clinically when alert, but this should not delay thoracolumbar spine clearance.
