Phrenic nerve conduction time in Guillain-Barré syndrome. 1985

M Gourie-Devi, and G R Ganapathy

Phrenic nerve conduction was studied in 28 patients with Guillain-Barré syndrome. Conduction time was prolonged in 18 (64.3%) patients and serial studies showed progressive improvement with restoration of normal values in the majority by 12 weeks. The conduction abnormalities had a positive correlation with the extent of the disease, morbidity and mortality. Phrenic nerve conduction time was found to be a more sensitive parameter than vital capacity or median nerve motor conduction velocity in assessing the severity of the disease and predicting impending ventilatory failure.

D010791	Phrenic Nerve	The motor nerve of the diaphragm. The phrenic nerve fibers originate in the cervical spinal column (mostly C4) and travel through the cervical plexus to the diaphragm.	Nerve, Phrenic,Nerves, Phrenic,Phrenic Nerves
D011129	Polyradiculoneuropathy	Diseases characterized by injury or dysfunction involving multiple peripheral nerves and nerve roots. The process may primarily affect myelin or nerve axons. Two of the more common demyelinating forms are acute inflammatory polyradiculopathy (GUILLAIN-BARRE SYNDROME) and POLYRADICULONEUROPATHY, CHRONIC INFLAMMATORY DEMYELINATING. Polyradiculoneuritis refers to inflammation of multiple peripheral nerves and spinal nerve roots.
