Spinal cord injury (SCI) disrupts nervous system control, leading to cardiovascular and urinary autonomic dysfunctions. Early recognition and treatment of these complications are crucial for patient prognosis and quality of life.
Area of Science:
- Neurology
- Cardiology
- Urology
Background:
- Spinal cord injury (SCI) above the T6 vertebra disrupts sympathetic nervous system control.
- This leads to an imbalance between sympathetic and parasympathetic nervous system activity.
Purpose of the Study:
- To review the symptoms, treatment, and examination of autonomic disturbances in the cardiovascular and urinary systems following SCI.
Main Methods:
- A non-systematic literature search was conducted in the PubMed database.
Main Results:
- Acute SCI complications include bradyarrhythmias, hypotension, and neurogenic shock. Chronic complications involve orthostatic hypotension, autonomic dysreflexia (AD), cardiac atrophy, and urinary autonomic dysfunction (hyperreflexia/areflexia). AD, triggered by stimuli below the injury, can cause severe hypertension and potentially fatal outcomes.
- Urinary autonomic dysfunctions include detrusor and sphincter hyperreflexia or areflexia.
Conclusions:
- Patients with SCI face a high risk of cardiovascular and urinary autonomic complications, impacting prognosis and quality of life.
- Understanding these complications is vital for accurate diagnosis and effective management.
