ASIA classification, level-specific functional deficits, autonomic dysreflexia emergency management, neurogenic shock, respiratory considerations, and comprehensive nursing care for SCI patients.
1. SCI Classifications
Completeness: ASIA Impairment Scale
| Grade | Classification | Description |
|---|
| A | Complete | No motor or sensory function below neurological level, including S4–S5 (sacral segments). Poor prognosis for recovery. |
| B | Sensory Incomplete | Sensory but no motor function preserved below neurological level, including S4–S5 |
| C | Motor Incomplete | Motor function preserved below neurological level; more than half of key muscles grade <3 |
| D | Motor Incomplete | Motor function preserved below neurological level; at least half of key muscles grade ≥3 |
| E | Normal | Sensation and motor function normal in all segments |
Level-Specific Functional Deficits
| Level | Injury Name | Respiratory | Expected Function |
|---|
| C1–C3 | High cervical | No independent breathing — ventilator dependent | Minimal arm/hand; dependent for all ADLs; electrical wheelchair with mouth/head control |
| C4 | High cervical | Partial diaphragm; may need vent support; diaphragm pacing possible | Shoulder shrug; power wheelchair with head/mouth control |
| C5 | Mid-cervical | Diaphragm intact; may need assist for coughing | Shoulder/elbow flexion; can use power wheelchair with hand controls; limited self-feeding with adaptive equipment |
| C6 | Mid-cervical | Near normal; assisted cough | Wrist extension; tenodesis grasp; manual wheelchair on level surfaces; increased independence in ADLs |
| C7–C8 | Low cervical | Normal diaphragm; weak intercostals | Elbow extension/finger flexion; independent manual wheelchair; self-catheterization |
| T1–T6 | High thoracic | Partial intercostals affected; reduced cough | Full arm function; paraplegic; independent wheelchair; trunk balance impaired |
| T6–T12 | Low thoracic | Near-normal pulmonary function | Trunk control improving; independent wheelchair; ambulation with extensive bracing possible |
| L1–L5 | Lumbar | Normal | Hip flexion/knee extension preserved (L1–L2, L3–L4); ambulation with crutches/bracing |
| S1–S5 | Sacral | Normal | Mostly ambulatory; bowel/bladder dysfunction; sexual function affected |
2. Neurogenic Shock
Neurogenic shock occurs with injuries at T6 or above.
Loss of sympathetic outflow below the lesion → loss of vasoconstriction + loss of cardiac acceleration
Classic presentation: Hypotension + Bradycardia + Warm/flushed extremities (vasodilation)
(Contrast with all other shock types: septic/hemorrhagic = tachycardia + cool extremities)
Treatment:
- IV fluids (cautiously — avoid fluid overload; goal is filling a dilated vascular bed)
- Vasopressors: norepinephrine (vasoconstriction + inotrope) or phenylephrine (pure vasoconstriction)
- For bradycardia: atropine; avoid suctioning without preoxygenation (suctioning stimulates vagus → severe bradycardia)
- MAP goal: 85–90 mmHg for first 7 days post-acute SCI (to perfuse injured cord)
3. Autonomic Dysreflexia (AD) — Emergency
Definition: Exaggerated autonomic response to a stimulus below the level of injury. Occurs in lesions at T6 or above. A NURSING EMERGENCY.
Pathophysiology: Noxious stimulus below lesion → massive sympathetic discharge below injury → severe hypertension → baroreceptors sense hypertension → bradycardia + flushing/sweating ABOVE lesion (but cannot vasodilate below lesion — spinal cord severed)
Signs:
- Severe hypertension (SBP 200–300 mmHg) — greatest danger: stroke, MI, seizure, death
- Pounding headache (severe)
- Bradycardia (reflex)
- Profuse sweating and flushing ABOVE the injury level
- Pale, cool, piloerection (goosebumps) BELOW the injury level
- Blurred vision, anxiety, nasal congestion
Autonomic Dysreflexia Management (in order)
- SIT PATIENT UP immediately — orthostatic hypotension drops BP; head of bed 90°
- Find and eliminate the trigger (MOST IMPORTANT)
- Check Foley catheter first — kinked, clogged, full drainage bag? Relieve immediately
- Bladder distention: catheterize (use lidocaine gel liberally); irrigate obstructed catheter gently
- Bowel: check for fecal impaction — apply lidocaine gel; wait 5 minutes; then disimpact GENTLY
- Pressure areas: tight clothing, wrinkles in sheets, pressure ulcers, ingrown toenail
- Other triggers: sunburn, fracture, UTI, menstruation, labor contractions
- If BP remains elevated (>150 mmHg systolic): rapid-acting antihypertensives — nitroglycerin paste/SL, hydralazine, nifedipine (bite and swallow), nitroprusside IV in refractory cases
- Monitor BP q5 minutes while searching for trigger
- Notify physician immediately
4. Respiratory Considerations
| Issue | Levels Affected | Nursing Action |
|---|
| Ventilator dependence | C1–C3 (C4 variable) | Vent alarms = highest priority; manual ventilation (bag-valve-mask) always at bedside; never transport without backup ventilation |
| Weak/ineffective cough | C5 and above; T1–T6 | Quad-assist (manually-assisted) cough: position hands on lower rib cage, coordinate with cough effort; suction PRN; incentive spirometry |
| Atelectasis/pneumonia | All high SCI | Aggressive pulmonary toilet, frequent repositioning (at least q2h), assisted coughing, deep breathing, avoid sedating medications when possible |
| Bradycardia with suctioning | C4 and above | Pre-oxygenate; limit suction passes to 10–15 sec; monitor HR; atropine available |
5. Bladder and Bowel Management
- Bladder: Acute phase: Foley catheter (strict hourly UO monitoring). Long-term goal: intermittent catheterization (IC) q4–6h to prevent infections. Target UO 1500–2000 mL/day. Neurogenic bladder: upper motor = spastic/reflexive; lower motor = flaccid/atonic (overflow incontinence)
- Bowel: Neurogenic bowel program: consistent timing (after meals to use gastrocolic reflex), suppositories, digital stimulation, high fiber diet, stool softeners. Upper motor neuron lesions = reflex bowel (responds to digital stimulation). Lower motor neuron = areflexic (manual evacuation needed).
6. Pressure Injury Prevention
SCI patients have complete loss of protective sensation below the injury level — cannot feel pressure building. They are at extreme risk for pressure injuries.
- Reposition q2h minimum; specialty bed for unstable patients
- Inspect skin at every repositioning (especially sacrum, heels, scapulae, ears, elbows)
- Wheelchair patients: pressure reliefs every 15–30 min (raise up on arms for 15–30 sec or lean forward)
- Specialty cushions (ROHO gel cushion, Jay cushion); never have patient sit on flat hard surface
7. Spinal Precautions and Immobilization
- Maintain spinal alignment at all times until injury cleared by spine surgery team
- Cervical: cervical collar (hard collar — soft collars do NOT provide immobilization)
- Log-roll with pillow between knees when turning (3+ people for high cervical)
- Cervical traction (Gardner-Wells tongs or halo vest) — pin site care; do NOT remove halo without physician order; keep allen wrench at bedside for emergency
- Thoracolumbar: thoracolumbosacral orthosis (TLSO brace); apply before getting patient OOB
NCLEX High-Yield: Spinal Cord Injury
- Neurogenic shock: hypotension + bradycardia + warm/flushed skin (unlike other shocks)
- Autonomic dysreflexia: T6 and above; sit patient up FIRST; most common trigger = bladder distention
- AD: flushing/sweating ABOVE injury; pallor/piloerection BELOW injury
- C1–C3: ventilator dependent; C4: may need vent; C5+: independent breathing
- Diaphragm = C3, C4, C5 ("C3, 4, 5 keeps the diaphragm alive")
- MAP goal after acute SCI: 85–90 mmHg × 7 days (spinal cord perfusion)
- Quad-assist (manually-assisted) cough for patients with weak cough (cervical/high thoracic)
- Skin inspection at every turn; reposition q2h minimum
- Hard cervical collar (NOT soft) provides immobilization
- Halo vest: keep allen wrench at bedside for CPR chest access
