Guillain-Barré syndrome is an acute polyneuropathic disorder that causes muscle weakness, loss of reflexes, and numbness in the limbs and face. It occurs when the immune system mistakenly attacks the peripheral nervous system. The symptoms can range from mild tingling to total paralysis. The disorder is usually triggered by a bacterial or viral infection. Treatment focuses on speeding recovery through measures like plasmapheresis, IVIG, respiratory therapy, and monitoring for complications like respiratory failure or paralysis. Nurses help manage symptoms, provide education, and address problems with mobility, swallowing, and sensation that arise due to the disease process.
