Spinal Cord Injury nursing care: what to assess and what to do first
Written and reviewed by Dana Whitfield, RN, MSN · 6 min read · Updated September 2026
Short answer
Spinal cord injury nursing care starts with the level of injury, because the level decides the deficit. Anything at or above T6 brings a lifelong risk of autonomic dysreflexia, a hypertensive emergency triggered by an unfelt stimulus below the injury, so every future admission for that patient needs a bladder and bowel check before anything else is assumed.
The clinical picture
Spinal cord injury disrupts motor, sensory, and autonomic pathways at and below the level of the lesion. A cervical injury can produce tetraplegia and, if high enough, compromise the phrenic nerve and diaphragmatic breathing. A thoracic or lumbar injury produces paraplegia with the upper body and arms spared. The level is not academic detail, it is the single fact that predicts everything else about the patient's care.
Injuries at or above T6 carry a specific and permanent risk: autonomic dysreflexia. Above this level, the sympathetic nervous system loses its normal inhibitory control from higher centres, so a stimulus below the injury, most often a full bladder or impacted bowel, can trigger an unchecked sympathetic surge. The patient may not feel the triggering stimulus at all, which is what makes this presentation different from ordinary hypertension. Spinal shock in the acute phase, a temporary loss of all reflex activity below the injury, further complicates early assessment and can mask the eventual severity of the deficit.
Assessment: what to look for and in what order
Establish the neurological level and completeness of injury first, using a standardised motor and sensory exam, because this single data point reframes every subsequent assessment. Airway and breathing come next for any cervical injury, since a lesion at C3-C5 threatens diaphragmatic function through the phrenic nerve, and even lower cervical injuries reduce intercostal muscle use and cough strength.
For any injury at T6 or above, build a standing awareness of autonomic dysreflexia into every shift: sudden severe headache, flushing and sweating above the injury level, pale skin and goosebumps below it, and a blood pressure spike are the signature. Check for bladder distension and bowel impaction as the first two suspects whenever these signs appear, since they cause the large majority of episodes. Assess for spinal shock in the acute phase by noting flaccid paralysis and absent reflexes below the level, and monitor bradycardia and hypotension separately from dysreflexia, since neurogenic shock produces the opposite haemodynamic picture.
Immediate interventions
Immobilise the spine and maintain neutral alignment until injury is ruled out or stabilised, using a rigid collar and logrolling technique for any position change or turn. For injuries at or above the mid-cervical level, keep intubation equipment accessible and monitor respiratory effort closely, since fatigue can develop even with initially adequate breathing.
If autonomic dysreflexia occurs, sit the patient upright immediately to use gravity to lower blood pressure, then find and remove the trigger before anything else: check the urinary catheter for kinks or blockage first, then check for bowel impaction, and loosen any tight clothing or constrictive devices. Monitor blood pressure every few minutes during the episode and be ready to administer a fast-acting antihypertensive if the trigger cannot be removed quickly, since untreated dysreflexia can progress to seizure, stroke, or death. For neurogenic shock, expect the opposite pattern, bradycardia and hypotension, and manage with fluids and vasopressors rather than antihypertensives.
Ongoing nursing management
Bladder and bowel programmes are not peripheral to spinal cord injury care, they are central, because an unmanaged bladder is the leading trigger for dysreflexia in patients above T6. Establish intermittent catheterisation or an indwelling system per protocol and a scheduled bowel programme, and document baseline patterns so future distension is caught early rather than discovered mid-crisis.
Skin integrity requires the same rigor: reposition on a strict schedule, since loss of sensation means the patient cannot feel the early warning signs of a pressure injury. Deep vein thrombosis prophylaxis matters throughout the immobile phase, given the combined risk from paralysis and vascular changes after cord injury. Respiratory care continues past the acute phase for higher-level injuries, with incentive spirometry and assisted coughing techniques to prevent pneumonia. Temperature regulation can also be impaired below the injury level, so monitor for both hyperthermia and hypothermia rather than assuming normal thermoregulation.
Patient and family education
Every patient with an injury at or above T6, along with their family, needs explicit teaching on autonomic dysreflexia before discharge: what it feels like, what causes it, and that it is a medical emergency requiring immediate action, not something to wait out. Teach the sit-up-first response and the trigger-checking sequence so the family can act even before emergency services arrive.
Cover the bladder and bowel programme in enough detail that the patient or caregiver can execute it independently, since lapses here are the most common preventable cause of both dysreflexia and infection. Teach daily skin checks using a mirror or a caregiver's help for areas the patient cannot see or feel, and reinforce that pressure injuries can develop without any pain to warn them. Address the scope of adjustment ahead, including mobility equipment, home modifications, and referral to rehabilitation and psychological support, since adaptation to a spinal cord injury is a long process that outlasts the hospital stay.
How this appears on the NCLEX
NCLEX questions on spinal cord injury frequently test whether you connect the injury level to the correct risk, particularly autonomic dysreflexia in a patient with a cervical or high thoracic lesion who develops sudden hypertension and headache. The expected first action is almost always to sit the patient up and check the bladder before reaching for medication.
Expect distractor options that treat dysreflexia like ordinary hypertension, offering to lower the head of the bed or simply medicate without removing the trigger; both are wrong because they miss the underlying cause. Questions also test differentiating autonomic dysreflexia from neurogenic shock, since one produces hypertension and bradycardia together and the other produces hypotension, and mixing up the management for each is a classic wrong-answer trap.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our neurological practice questions are the closest set to what this page covers.
Common questions
What is the first thing to do for suspected autonomic dysreflexia?
Sit the patient upright immediately to lower blood pressure through gravity, then look for the trigger, starting with a kinked or blocked urinary catheter. This comes before medicating, since removing the cause often resolves the episode without further intervention.
Why does autonomic dysreflexia only happen above T6?
The splanchnic sympathetic outflow, which supplies major vasoconstrictor fibres, exits the spinal cord around T5-T6. Above that level, an injury separates this outflow from the brain's regulatory control, so a stimulus below the injury triggers an unchecked sympathetic surge that the brain cannot dampen.
How is neurogenic shock different from autonomic dysreflexia?
Neurogenic shock occurs in the acute phase after a high spinal cord injury and causes hypotension with bradycardia, from loss of sympathetic vascular tone. Autonomic dysreflexia occurs later, after spinal shock resolves, and causes hypertension, usually with bradycardia, triggered by an unfelt stimulus below the injury. They call for opposite treatment: fluids and vasopressors for one, sitting up and trigger removal for the other.
What is spinal shock and how long does it last?
Spinal shock is a temporary loss of all reflex activity, motor function, and sensation below the level of injury, occurring immediately after the trauma. It typically resolves over days to a few weeks, and its resolution, marked by the return of reflexes such as the bulbocavernosus reflex, is what allows an accurate assessment of the injury's true completeness.
What is the most common trigger for autonomic dysreflexia to check first?
Bladder distension, most often from a blocked, kinked, or overly full catheter, accounts for the large majority of episodes. Bowel impaction is the second most common cause, so check both in that order before assuming any other trigger.
