Guillain-Barré syndrome: The Daily PANCE Blueprint
A 19-year-old man is admitted to the hospital due to progressive weakness in the lower extremities. He initially experienced tingling in his toes 7 days ago, which has since progressed to weakness and difficulty walking. He also reports difficulty swallowing and facial weakness. The patient had a gastrointestinal illness 3 weeks ago but is otherwise healthy. Temperature is 36.8°C (98.2°F), blood pressure is 115/75 mm Hg, pulse is 90/min, and respirations are 24/min. Neurologic examination reveals 1/5 strength in the lower extremities and 3/5 strength in the upper extremities. Reflexes are absent in the lower extremities and decreased in the upper extremities. The patient has difficulty holding his head up. Which of the following is the best next step in the management of this patient?
A. Intravenous immunoglobulin therapy
B. Mechanical ventilation
C. Spinal MRI
D. Muscle biopsy
E. Lumbar puncture
Answer and topic summary
The answer is B. Mechanical ventilation
Guillain-Barré syndrome (GBS): Guillain-Barré syndrome is an immune-mediated demyelinating polyneuropathy that often follows a gastrointestinal or respiratory infection. The condition typically presents with ascending weakness and areflexia. Respiratory failure is a life-threatening complication of GBS, and monitoring of pulmonary function is critical. Mechanical ventilation is required when there is evidence of respiratory compromise, such as difficulty swallowing, facial weakness, and poor respiratory effort.
Incorrect Answers:
- A. Intravenous immunoglobulin therapy – While IVIG is a key treatment for GBS, immediate respiratory support takes priority in a patient with signs of respiratory failure.
- C. Spinal MRI – This could reveal nerve root enhancement but is not critical in the acute management of respiratory compromise in GBS.
- D. Muscle biopsy – This is unnecessary for diagnosing GBS and does not address the immediate need for respiratory support.
- E. Lumbar puncture – Though it can support the diagnosis of GBS by showing elevated protein with normal cell count (albuminocytologic dissociation), it is not urgent in the context of impending respiratory failure.
