Guillain-Barre Syndrome
Key Points
- Guillain-Barre syndrome is a rare autoimmune disorder causing progressive weakness and possible paralysis.
- Weakness often begins in both legs and ascends to arms and upper body.
- Progression can occur over hours to weeks, and respiratory-muscle involvement can be fatal.
- Recovery commonly starts within weeks, but full recovery duration is variable and residual deficits may persist.
- Core treatments include plasma exchange and high-dose immunoglobulin therapy.
Pathophysiology
GBS is an autoimmune-mediated peripheral nerve disorder characterized by rapidly progressive weakness, often with ascending distribution from lower to upper extremities. In severe cases, respiratory muscles are affected and life-threatening ventilatory failure can occur.
Common infectious antecedents include Campylobacter jejuni gastroenteritis and viral illnesses such as influenza, cytomegalovirus, and Epstein-Barr virus.
Classification
- Progressive weakness phase: Rapidly evolving ascending motor weakness with possible progression to paralysis.
- Recovery phase: Improvement usually begins within weeks but may extend over months to years.
Nursing Assessment
NCLEX Focus
Trend progression speed and respiratory involvement continuously.
- Assess distribution and progression of weakness and paresthesia.
- Assess for signs of respiratory-muscle compromise and fatigue.
- Assess functional decline pace to support timely escalation.
- Anticipate electrophysiologic support testing: NCV often shows slowed peripheral conduction in neuropathic patterns such as GBS.
Nursing Interventions
- Escalate immediately when weakness progresses rapidly or breathing becomes compromised.
- Coordinate definitive therapy pathways (plasma exchange and high-dose immunoglobulin) with close monitoring.
- Support mobility safety and ADL assistance during progressive and recovery phases.
Respiratory Failure Risk
GBS can deteriorate quickly; delayed escalation can be fatal when respiratory muscles are affected.
Pharmacology
| Drug Class | Examples | Key Nursing Considerations |
|---|---|---|
| immune-globulins | High-dose IVIG | Used as disease-targeted therapy to reduce autoimmune attack burden in acute GBS management. |
Clinical Judgment Application
Clinical Scenario
A patient reports bilateral leg tingling that progressed to arm weakness over 48 hours with increasing shortness of breath.
- Recognize Cues: Ascending weakness with early respiratory involvement.
- Analyze Cues: Acute autoimmune neuropathy progression is likely.
- Prioritize Hypotheses: Prevent respiratory failure and irreversible complications.
- Generate Solutions: Activate urgent neurologic/respiratory monitoring and treatment pathway.
- Take Action: Prepare for rapid supportive escalation and disease-specific therapy.
- Evaluate Outcomes: Progression slows and respiratory status remains supported.
