Spinal cord injury (SCI) is a disruption of motor, sensory, or autonomic function caused by damage to the spinal cord or its nerve roots. In the United States, approximately 18,000 new SCI cases occur each year, with motor vehicle crashes, falls, violence, and sports accounting for the vast majority. For nursing students, SCI is one of the most concept-dense topics on the NCLEX — it demands simultaneous command of neuroanatomy, shock physiology, respiratory assessment, and emergency management. The decisions nurses make in the first hours after SCI — and in managing chronic complications like autonomic dysreflexia — are genuinely life-or-death. This reference covers the full SCI nursing picture: classification, pathophysiology, priority emergencies, system-by-system interventions, shock comparison, medications, and six NCLEX-style practice questions.
Fast-scan: SCI key facts
| Parameter | Value / Key Point |
|---|---|
| Complete SCI (ASIA A) | No motor or sensory function below lesion |
| Incomplete SCI (ASIA B–D) | Some preservation of function below lesion |
| Neurogenic shock | T6 and above — bradycardia + hypotension + warm/dry skin |
| Spinal shock | Flaccid paralysis + areflexia below lesion; resolves with return of Babinski reflex |
| Autonomic dysreflexia trigger | Lesion T6 and above; most common cause = bladder distension |
| AD emergency threshold | SBP ≥150 mmHg (or >20 mmHg above baseline) |
| AD first intervention | Sit patient upright; find and remove trigger |
| C3-C5 mnemonic | ”C3-4-5 keeps the diaphragm alive” — injury here = respiratory failure |
| DVT risk | Very high in SCI — LMWH prophylaxis (e.g., enoxaparin) initiated within 72 hours |
| Skin | Insensate skin below lesion — reposition every 2 hours minimum |
SCI classification and levels
The ASIA impairment scale
The American Spinal Injury Association (ASIA) impairment scale classifies the degree of neurological deficit after SCI. It is the universal standard used in clinical practice and research, and understanding it allows nurses to communicate precisely about a patient’s functional status.
| ASIA Grade | Description | Function below lesion |
|---|---|---|
| A — Complete | No sensory or motor function preserved in sacral segments S4-S5 | None |
| B — Sensory incomplete | Sensory but not motor function preserved below lesion, including S4-S5 | Sensation only |
| C — Motor incomplete | Motor function preserved; more than half of key muscles below lesion have grade <3 | Weak movement |
| D — Motor incomplete | Motor function preserved; at least half of key muscles below lesion have grade ≥3 | Functional movement |
| E — Normal | Sensory and motor function normal | Normal |
ASIA A represents the most severe injury. ASIA E represents neurological recovery to normal. Most patients fall somewhere on the continuum. The distinction between complete and incomplete injury is clinically important: incomplete injuries carry significantly better prognosis for recovery of function, particularly if initial spinal shock obscures the true picture.
Neurological level and expected deficits
The neurological level of injury (NLI) is the most caudal level at which both motor and sensory function are intact. Level-specific deficits follow predictable patterns because each spinal segment innervates specific muscles and dermatomes.
| Level | Key deficits | Respiratory impact | Key clinical point |
|---|---|---|---|
| C1–C2 | Quadriplegia; no independent respiratory function | Ventilator-dependent | Immediate intubation; cannot breathe without support |
| C3–C5 | Quadriplegia; diaphragm partially or fully impaired | High risk of respiratory failure | ”C3-4-5 keeps the diaphragm alive” — C3 injury = no diaphragm |
| C5–C6 | Quadriplegia; shoulder shrug, elbow flexion preserved; hand function absent | Weakened cough; needs assistance | Cannot independently clear secretions |
| C7–C8 | Quadriplegia; elbow extension present; limited hand and finger function | Accessory muscle use | Can operate manual wheelchair with training |
| T1–T6 | Paraplegia; full arm function; trunk control impaired | Intercostal muscles impaired; strong cough effort reduced | At risk for autonomic dysreflexia (T6 and above) |
| T7–T12 | Paraplegia; partial to full trunk control preserved | Near-normal respiratory function | Better sitting balance, lower injury = better outcomes |
| L1–L5 | Variable lower extremity deficits; bowel/bladder often affected | Normal | Hip flexion may be preserved at L1-L3 |
| S1–S5 | Bowel, bladder, sexual dysfunction; minimal motor deficit | Normal | Cauda equina = lower motor neuron picture |
Pathophysiology: primary and secondary injury
Primary injury
Primary SCI is the mechanical damage that occurs at the moment of impact — compression, contusion, laceration, or transection of the cord. This initial injury is irreversible. Burst fractures, fracture-dislocations, and hyperflexion injuries (the most common mechanism in motor vehicle crashes) all cause primary injury through cord compression, shear forces, or direct laceration.
Secondary injury
Secondary injury is the cascade of pathological events that follows the primary mechanical insult. It begins within minutes and can continue for days to weeks. The key mechanisms include:
- Vascular disruption: Hemorrhage into cord tissue, vasospasm, and loss of autoregulation reduce perfusion to the injured segment. Hypotension at any point in the acute phase worsens ischemia — maintaining MAP ≥85–90 mmHg is a priority in acute SCI management.
- Glutamate excitotoxicity: Damaged neurons release excessive glutamate, activating NMDA receptors and triggering calcium influx, which drives cellular death beyond the primary injury zone.
- Inflammation: Microglial activation, cytokine release, and neutrophil infiltration extend injury over the first 24–72 hours.
- Apoptosis: Programmed cell death in oligodendrocytes causes demyelination of intact axons, expanding functional loss beyond the anatomical lesion.
The implication for nursing: every intervention that prevents hypotension, hypoxia, or hyperthermia in the acute phase is directly neuroprotective. These are not merely supportive measures — they modify injury extent.
Spinal shock
Spinal shock is a transient physiological state — not a hemodynamic emergency — that occurs immediately after SCI. It is characterized by flaccid paralysis, complete loss of reflexes (areflexia), and loss of sensation below the level of injury. Spinal shock reflects temporary suppression of all spinal cord function below the lesion.
Key features of spinal shock:
- Begins immediately at injury
- Lasts hours to days (occasionally weeks)
- Resolution is marked by the return of the bulbocavernosus reflex and Babinski sign
- After resolution, upper motor neuron (UMN) injuries develop spasticity and hyperreflexia; lower motor neuron (LMN) injuries remain flaccid
Do not confuse spinal shock (neurological) with neurogenic shock (hemodynamic). They can occur simultaneously, but they are separate entities.
Neurogenic shock
Neurogenic shock is a distributive shock caused by sudden loss of sympathetic vasomotor tone in SCI at or above T6. Loss of sympathetic outflow causes vasodilation and loss of cardiac chronotropy, producing the triad of:
- Hypotension (systolic blood pressure <90 mmHg)
- Bradycardia (HR typically <60 bpm — distinguishes this from hypovolemic shock)
- Warm, dry, flushed skin below the lesion (vasodilated, not vasoconstricted)
Neurogenic shock can persist for days to weeks. Management involves IV fluid resuscitation plus vasopressors (norepinephrine or dopamine) and atropine or temporary pacing for refractory bradycardia. The bradycardia is the key differentiating feature on NCLEX — hypovolemic shock produces tachycardia, neurogenic shock produces bradycardia.
Autonomic dysreflexia: priority emergency
Autonomic dysreflexia (AD) is a potentially life-threatening syndrome that occurs in patients with SCI at or above T6. It is caused by an uncontrolled, massive sympathetic discharge below the lesion in response to a noxious stimulus that the patient cannot perceive. If unrecognized and untreated, AD can produce hypertensive stroke, seizures, or death. Nurses must be able to recognize and act on it immediately.
Pathophysiology of autonomic dysreflexia
A noxious stimulus below the lesion (e.g., a full bladder) sends afferent signals up the spinal cord. In the intact nervous system, the brain modulates this signal and the sympathetic response is proportionate. In SCI above T6, sympathetic inhibitory signals from the brain cannot travel past the injury. The result is an uninhibited sympathetic surge — massive peripheral vasoconstriction below the lesion, causing severe hypertension. Baroreceptors detect the hypertension and trigger compensatory responses — bradycardia and vasodilation above the lesion (producing flushed, sweaty face and neck) — but these cannot override the ongoing peripheral vasoconstriction.
Trigger causes
| Cause | Frequency | Clinical pearl |
|---|---|---|
| Bladder distension | #1 most common | Check Foley for kinks, clots, or obstruction first |
| Urinary tract infection | Common | Bladder irritation without visible retention |
| Bowel distension / fecal impaction | #2 most common | Digital rectal exam — use anesthetic lubricant |
| Pressure ulcer / skin breakdown | Common | Check bony prominences below lesion |
| Tight clothing / constrictive device | Frequent | Check leg bags, shoes, abdominal binders |
| Fracture or trauma below lesion | Occasional | Patient cannot feel the injury |
| Surgical or procedural stimulation | Situational | Warn OR team in advance |
| Sexual activity / menstruation | Situational | Discuss with patient in teaching |
Signs and symptoms
The hallmark presentation of AD includes:
- Sudden severe hypertension: SBP ≥150 mmHg (some guidelines define the threshold as >20 mmHg above the patient’s typical baseline, which may be in the 90s–100s due to chronic hypotension from neurogenic dysfunction)
- Pounding headache: The most common symptom reported by patients; described as sudden onset, throbbing, severe
- Profuse diaphoresis above the lesion (particularly face, neck, and shoulders)
- Flushing above the lesion (from compensatory vasodilation)
- Piloerection (“goosebumps”) above the lesion
- Bradycardia (reflex response to hypertension)
- Nasal congestion
- Blurred vision, anxiety
- Below the lesion: skin may be pale and cool (vasoconstricted)
Immediate nursing interventions — in order
- Sit the patient upright (or elevate the head of the bed to 90°) — this uses orthostatic pooling to lower blood pressure. Do this immediately, before anything else.
- Loosen any constrictive clothing — waistbands, leg bags, shoes, compression stockings.
- Check the urinary catheter — look for kinks, clots, or obstruction. If catheter is blocked, irrigate gently or replace. If no catheter is in place, catheterize immediately.
- Check for fecal impaction — perform digital rectal exam using an anesthetic lubricant gel (lidocaine) to minimize further stimulation during the exam. Do not remove impaction without anesthetic gel — this will worsen the AD.
- Check skin — inspect all pressure points below lesion for pressure ulcer, skin breakdown, or any trauma.
- Monitor blood pressure every 2–5 minutes while searching for and removing the trigger.
- If SBP remains ≥150 mmHg after trigger is addressed, administer a rapid-onset antihypertensive as ordered. First-line agents include:
- Nitropaste (nitroglycerin ointment): Applied above the lesion; easily removed if BP drops too low
- Nifedipine (short-acting): Bite-and-swallow 10 mg capsule — note: sublingual nifedipine is no longer recommended due to rapid, unpredictable drops
- Hydralazine IV in the inpatient setting
- Call the rapid response team if BP is not controlled within 10–15 minutes or if neurological changes (altered consciousness, visual changes, seizure) develop.
- Document the episode — triggers found, BP values, interventions, response, and time to resolution.
Respiratory management
Why respiratory failure is the primary cause of SCI death
Respiratory compromise is the leading cause of death in acute SCI, and the risk is directly proportional to the level of injury. Understanding which muscles support breathing — and which spinal segments innervate them — is essential for anticipating and preventing respiratory failure.
The C3-C5 rule: The phrenic nerve, which innervates the diaphragm, arises from the C3, C4, and C5 nerve roots. “C3-4-5 keeps the diaphragm alive.” Any SCI at or above C3 results in complete diaphragmatic paralysis, requiring immediate intubation and mechanical ventilation. Injuries at C4-C5 may spare partial diaphragmatic function but still carry high risk.
Intercostal muscles (T1–T12) assist with the expansive force of breathing and forced exhalation. Injuries above T12 reduce respiratory reserve and cough effectiveness progressively.
Abdominal muscles (T6–T12) are required for forceful cough and exhalation. Loss of abdominal muscle function dramatically impairs secretion clearance.
Respiratory nursing priorities by level
- C1–C3: Immediate ventilator dependence; tracheostomy is the standard long-term airway; suctioning for secretion clearance
- C4–C5: Ventilator dependence likely initially; weaning potential variable; assisted cough maneuvers required
- C6–T6: Spontaneous breathing possible but weakened cough; quad-assist cough (nurse places hands on abdomen during cough effort), incentive spirometry, frequent repositioning
- T7 and below: Near-normal respiratory function; secretion clearance less compromised; still monitor for atelectasis
Key respiratory interventions
- Continuous pulse oximetry; target SpO₂ ≥95%
- Frequent respiratory rate assessment and breath sound auscultation
- Incentive spirometry every 1–2 hours while awake
- Assisted (quad-assist) cough technique for C5–T6 injuries
- Suctioning when needed for ventilator-dependent patients
- Head of bed elevated 30–45° to optimize diaphragm excursion
- Serial ABGs or end-tidal CO₂ monitoring for evolving respiratory failure
- Early consultation with respiratory therapy and pulmonology
Nursing interventions by body system
| System | Priority assessments | Key nursing interventions | Rationale |
|---|---|---|---|
| Neurological | Hourly neuro checks (level of injury, motor strength, sensation); motor/sensory changes from baseline | Log any change immediately; avoid hypotension and hypoxia; spinal precautions until cleared | Secondary injury is worsened by ischemia; every mmHg of SBP below 90 extends the injury |
| Cardiovascular | BP, HR, MAP (target MAP ≥85–90 mmHg in acute phase); cardiac rhythm for bradycardia (T6 and above) | Vasopressors (norepinephrine) for neurogenic shock; atropine for bradycardia; SCDs + LMWH for DVT prophylaxis | Neurogenic shock = vasodilation + bradycardia; DVT risk in SCI is very high due to immobility and loss of calf muscle pump |
| Respiratory | RR, SpO₂, breath sounds, ABG; note lesion level (C3-5 = diaphragm) | Assisted cough; incentive spirometry; suctioning; HOB 30–45°; intubation for C1-C4 injuries | Respiratory failure is the #1 cause of SCI death; proactive management prevents intubation in lower injuries |
| GI | Bowel sounds; ileus (acute); abdominal distension; last bowel movement | NPO/NG tube if ileus; H2 blocker or PPI (stress ulcer prophylaxis — Cushing’s ulcer); bowel program for chronic SCI (glycerin suppository, timed evacuation) | Neurogenic bowel = loss of voluntary control; paralytic ileus common in acute phase; stress ulcers frequent in acute CNS injury |
| GU | Urinary retention (acute); UTI signs; catheter patency | Indwelling Foley or intermittent catheterization every 4–6 hours; strict I&O; keep catheter patent; UTI prevention | Neurogenic bladder = inability to void volitionally; retention is the #1 trigger for autonomic dysreflexia |
| Skin | Bony prominences every 2 hours; all insensate areas below lesion | Reposition every 2 hours minimum; specialty pressure-relief mattress; moisture management | Patient cannot feel pressure injury developing; SCI patients have extremely high pressure ulcer risk due to immobility + insensate skin |
| Musculoskeletal | Joint ROM; spasticity (subacute/chronic); contracture | Passive ROM exercises; anti-spasticity medications (baclofen); proper positioning with splints | Paralyzed limbs develop contractures rapidly; spasticity develops weeks after spinal shock resolves |
| Psychosocial | Depression, anxiety, grief response; suicidality (higher in SCI population) | Therapeutic communication; acknowledge loss; involve case management, social work, chaplaincy; depression screening tools (PHQ-9) | SCI involves sudden, profound loss of independence and body image; depression affects >30% of SCI patients; suicide risk is meaningfully elevated |
Spinal shock vs neurogenic shock vs hypovolemic shock
This distinction is among the most commonly tested SCI topics on NCLEX. The three conditions co-occur in the polytrauma patient, but their mechanisms, presentations, and treatments differ.
| Feature | Spinal shock | Neurogenic shock | Hypovolemic shock |
|---|---|---|---|
| Definition | Transient loss of all spinal cord function below lesion | Distributive shock from loss of sympathetic tone | Shock from intravascular fluid/blood loss |
| Mechanism | Neurological suppression of cord below lesion | Loss of sympathetic vasomotor tone (T1–L2 outflow) | Inadequate circulating volume |
| Level required | Any SCI level | T6 and above | Any cause |
| Blood pressure | Not a hemodynamic state | Low (vasodilation) | Low (vasoconstriction) |
| Heart rate | Not affected hemodynamically | Bradycardia (key distinguisher) | Tachycardia (key distinguisher) |
| Skin | N/A | Warm, flushed, dry | Cool, pale, clammy |
| Urinary output | Not directly affected | Low | Low |
| Duration | Hours to weeks; resolves with return of reflex activity | Days to weeks; resolves as cord swelling subsides | Until volume replaced |
| Treatment | Supportive; watch for return of reflexes | IV fluids + vasopressors + atropine for bradycardia | Aggressive IV fluids, blood products, surgery for source |
| Key NCLEX clue | Flaccid paralysis + areflexia after acute SCI | SCI above T6 + bradycardia + hypotension + warm skin | Trauma + tachycardia + cool clammy skin |
Medications used in SCI nursing care
Acute phase
Methylprednisolone: Once considered standard of care for acute SCI, high-dose methylprednisolone (30 mg/kg IV bolus followed by 5.4 mg/kg/hr infusion for 23–47 hours) fell out of favor due to lack of convincing benefit and increased rates of pneumonia, sepsis, and GI bleeding in clinical trials. Current guidelines (AANS, Congress of Neurological Surgeons) do not recommend it as standard treatment; some centers may use it selectively with shared decision-making. Nursing students should know it exists and understand the controversy.
Vasopressors: Norepinephrine is the vasopressor of choice for neurogenic shock — it provides both alpha-1 (vasoconstriction) and beta-1 (positive chronotropy) effects. Dopamine is an alternative. Phenylephrine is generally avoided because it causes reflex bradycardia, worsening the already-present bradycardia of neurogenic shock.
Atropine: For symptomatic bradycardia in neurogenic shock. Temporary transvenous pacing may be needed for refractory bradycardia.
Subacute and chronic phase
| Medication | Class | Indication | Key nursing considerations |
|---|---|---|---|
| Baclofen | GABA-B agonist / antispastic | Spasticity after SCI | Abrupt withdrawal causes seizures, hallucinations — never stop suddenly; intrathecal baclofen pump patients are at high risk if pump malfunctions |
| Oxybutynin (Ditropan) | Anticholinergic | Neurogenic bladder (overactivity) | Dry mouth, constipation, urinary retention, confusion in elderly; monitor bladder emptying |
| Tamsulosin (Flomax) | Alpha-1 blocker | Neurogenic bladder (outflow obstruction) | Orthostatic hypotension — caution in already-hypotensive SCI patients |
| Docusate (Colace) | Stool softener | Bowel program; constipation | Part of the standard neurogenic bowel regimen; schedule at the same time daily |
| Bisacodyl | Stimulant laxative | Bowel program (reflexic bowel, T1-S2) | Used as suppository or oral; triggered by reflex activity above the lesion |
| Enoxaparin (Lovenox) | LMWH anticoagulant | DVT prophylaxis | Initiated within 72 hours of injury in most guidelines; monitor for bleeding; anti-Xa monitoring may be used |
| Gabapentin / pregabalin | Anticonvulsant (off-label) | Neuropathic pain | Dizziness and sedation; avoid abrupt discontinuation |
| Antihypertensives (PRN) | Various | Autonomic dysreflexia | Nitropaste above lesion (removable), short-acting nifedipine PO; remove trigger first |
NCLEX-style practice questions
Question 1
A nurse is caring for a patient with a T4 complete SCI who suddenly reports a pounding headache. Assessment reveals BP 178/102 mmHg, HR 52 bpm, flushing above the nipple line, and diaphoresis on the face and neck. What is the nurse’s priority action?
A. Administer IV labetalol as prescribed B. Notify the physician immediately C. Sit the patient upright and check the urinary catheter D. Obtain a STAT ECG to evaluate the bradycardia
Correct answer: C
Rationale: This is a classic presentation of autonomic dysreflexia — hypertensive crisis with bradycardia, flushing, and diaphoresis above the T4 lesion in a patient with SCI at or above T6. The priority nursing action is to sit the patient upright (using orthostatic pooling to reduce BP) and identify the trigger. Bladder distension from a kinked or occluded catheter is the most common cause. Finding and removing the trigger is the definitive treatment. Antihypertensives come only after positioning and trigger removal; calling the physician is appropriate but secondary to immediate nursing action; the ECG would not address the cause.
Question 2
A nurse is assessing a patient 6 hours after a C5 SCI sustained in a diving accident. The patient currently requires supplemental oxygen via face mask and has a respiratory rate of 28 breaths/min. Which finding would require the most immediate intervention?
A. The patient has no sensation in both hands B. SpO₂ dropping from 96% to 90% despite oxygen C. The patient is unable to shrug shoulders D. Foley catheter output is 25 mL over the last hour
Correct answer: B
Rationale: C5 injury places the phrenic nerve at risk — C3, C4, and C5 innervate the diaphragm. Declining SpO₂ despite supplemental oxygen signals impending respiratory failure, which is the most immediately life-threatening complication at this level. Respiratory failure is the leading cause of death in acute SCI. The absence of hand sensation (A) is expected at C5. Inability to shrug shoulders (C) suggests possible C4 involvement and is worth documenting but is not immediately life-threatening. The low urine output (D) should be monitored but does not require the same immediate intervention as hypoxia.
Question 3
A patient with a T2 complete SCI is admitted to the ICU with BP 78/50 mmHg and HR 44 bpm. Skin is warm and dry. The patient sustained no other injuries. Which type of shock does this presentation most likely represent?
A. Hypovolemic shock B. Cardiogenic shock C. Neurogenic shock D. Septic shock (warm phase)
Correct answer: C
Rationale: Neurogenic shock occurs with SCI at or above T6 due to loss of sympathetic vasomotor tone. The classic triad is hypotension + bradycardia + warm/dry skin below the lesion (vasodilation, not vasoconstriction). The bradycardia is the critical differentiator from hypovolemic shock (which produces tachycardia) and from septic shock warm phase (which typically presents with tachycardia). Cardiogenic shock presents with cool, clammy skin and pulmonary congestion. The T2 level and absence of other injuries confirm neurogenic etiology.
Question 4
A nurse is providing education to a patient with a T6 SCI who is preparing for discharge to a rehabilitation facility. Which statement by the patient indicates a need for further teaching about autonomic dysreflexia?
A. “I should check my bladder drainage tube every day for kinks or blockages.” B. “If I get a headache and my face is flushed, I should lie flat and call for help.” C. “I should wear loose-fitting clothing and empty my leg bag regularly.” D. “A pressure sore on my leg could cause an episode even though I can’t feel it.”
Correct answer: B
Rationale: Lying flat is the wrong response to an AD episode — the patient should sit upright (or elevate the head of the bed) to use orthostatic effects to reduce blood pressure. All other statements reflect accurate understanding: checking catheter patency (A) addresses the most common trigger; loose clothing and regular leg bag emptying (C) remove common triggers; pressure injuries below the lesion (D) are a recognized trigger even without sensation. This question tests whether students understand the positioning intervention — sitting up, not lying flat.
Question 5
A patient with a C6 SCI is 3 weeks post-injury and has developed spasticity in both lower extremities. The patient is currently on oral baclofen 20 mg three times daily. The patient reports wanting to stop the medication because it “doesn’t seem to be doing much.” What is the nurse’s priority response?
A. Agree that the patient has the right to refuse medication and document the refusal B. Advise the patient to taper the dose gradually over at least 1–2 weeks under medical supervision C. Tell the patient that spasticity will worsen immediately if baclofen is stopped D. Contact physical therapy to reassess the need for pharmacological spasticity management
Correct answer: B
Rationale: Abrupt discontinuation of baclofen — particularly at higher doses — can cause life-threatening withdrawal symptoms including seizures, hallucinations, hyperthermia, and rhabdomyolysis. This is the priority safety concern. Gradual tapering under medical supervision is mandatory. While patient autonomy (A) is important, the nurse has an obligation to ensure informed consent includes knowledge of withdrawal risks before the patient decides. Telling the patient spasticity will worsen (C) is less complete and does not address the withdrawal danger. Consulting PT (D) is appropriate but not the priority response when the patient has stated intent to stop the medication.
Question 6
A nurse receives a patient with a new complete SCI at T10. On assessment, there is flaccid paralysis and complete absence of reflexes below T10, including the bulbocavernosus reflex. Vital signs: BP 110/70 mmHg, HR 80 bpm. Which clinical judgment is most accurate?
A. The absence of reflexes confirms this is a permanent complete injury B. The normal heart rate indicates neurogenic shock has been ruled out C. The flaccid areflexia is consistent with spinal shock and may be temporary D. Urinary output monitoring is not a priority because the injury is below T6
Correct answer: C
Rationale: Spinal shock — flaccid paralysis and complete areflexia below the lesion — is a transient physiological state that occurs immediately after SCI regardless of whether the injury is ultimately complete or incomplete. The resolution of spinal shock is marked by the return of reflexes (starting with the bulbocavernosus reflex). During spinal shock, it is impossible to determine whether the injury will be complete (ASIA A) or incomplete (ASIA B–D). The true neurological picture only emerges after spinal shock resolves. The normal BP and HR (B) are reassuring but do not rule out neurogenic shock, which may present later. Urinary retention and bladder management (D) are priorities at all SCI levels, including T10, due to neurogenic bladder.
