Role of electrophysiological study in evaluation and diagnosis of guillain barre syndrome

Objective:
1. To evaluate electrophysiological features of GBS
2. To know about various GBS variants in studied population
Materials and Methods:
50 patients diagnosed as Guillain Barre Syndrome (GBS) fulfilling the criteria as modified by Asbury, admitted in the Medical wards of tertiary hospital, Ahmedabad, From June 2019 to June 2021. It was a prospective observational study.
Results:
In this prospective study of 50 patients with GBS (based on Asbury’s Criteria), it was found to be commonest in the age group below 50 years and there was a male preponderance. Electrophysiological studies conducted in all patients revealed demyelinating pattern in 15 patients, axonal pattern in 10 patients and mixed pattern in 25 patients.
Conclusions:
Mixed pattern is the most common pattern seen on electrophysiological studies. Axonal pattern has better recovery compare to demyelinating and mixed pattern. AIDP was the most common variant in studied population followed by AMAN variant and AMSAN variant respectively.
