Study Notes
Autonomic Dysreflexia
- Occurs when the sympathetic nervous system is stimulated, but the parasympathetic system doesn't adequately respond.
- Lesions below T6 prevent dysreflexia as the parasympathetic system counteracts the sympathetic response.
- Triggers are usually stimuli from below the lesion's dermatome level.
- Symptoms include:
- Extreme hypertension
- Severe headache
- Pallor below the spinal cord lesion's dermatome
- Blurred vision
- Diaphoresis (sweating)
- Restlessness
- Nausea
- Piloerection (goosebumps)
- Parasympathetic response:
- Bradycardia
- Flushing above the spinal cord lesion's dermatome (e.g., face, neck)
- Nasal stuffiness
Nursing Actions
- Position: Sit the client upright to reduce blood pressure from postural hypotension.
- Notification: Alert the healthcare provider immediately.
- Cause Identification & Treatment: Determine and address the underlying cause.
-
Distended Bladder: Common cause, address by:
- Inserting a catheter (using anesthetics)
- Checking for kinks/blockages in the catheter
- Irrigation if needed
- Fecal Impaction: Address by removing the impaction (using anesthetics).
- Environment: Adjust room temperature and block drafts. Remove tight clothing. Assess for injuries (e.g., fractures, infections).
- Monitoring: Continuous monitoring of vital signs for high blood pressure and bradycardia.
- Medication: Antihypertensives (e.g., nitrates, hydralazine) may be administered.
Client Education
- Understanding and preventing potential causes (e.g., blocked catheter, constipation) is key.
- Spreading fluid intake throughout the day is important if intake is increased, rather than drinking it all at once.
- Develop a personal action plan for episodes of dysreflexia.
