BackgroundElective intubation is advocated in Guillain-Barré syndrome (GBS) with bulbar palsy to prevent aspiration pneumonia and lung collapse. We evaluate the outcome of GBS patients with bulbar palsy, and also compare the risks and benefits of intubation and MV in them.Methods187 GBS patients with bulbar palsy from a cohort of 547 GBS registry were analyzed. Detailed clinical records and peak disability on a 0-6 GBS Disability Scale (GBSDS) were noted. The patients were intubated if arterial blood gas (ABG) analysis revealed hypoxia, hypercarbia or acidosis. The patients with normal ABG parameters were fed by nasogastric tube, and nursed in lateral position. Occurrence of pneumonia, in-hospital death and outcomes at 6-months were classified as complete (GBSDS <2), partial (GBSDS 2-3) and poor (GBSDS >3).Results76/187(40.6%) patients required MV, and they had a shorter duration of illness (p = 0.007), higher peak disability (p < 0.001), autonomic dysfunction (p < 0.001) and more frequently received IVIg (p = 0.02). Pneumonia (63% vs 10.8%; p < 0.001) and in-hospital deaths (7.9% vs 1.8%; p = 0.06) were more frequent in MV group compared to nasogastric fed group. At 6-months,104 (55.6%) patients recovered completely. On multivariate analysis, the independent predictors of poor outcome were peak disability [Adjusted Odds Ratio (AOR) 9.84, 95% Confidence Interval (CI) 3.15-30.74, p < 0.0001], day of hospitalization from disease onset (AOR 1.09, 95% Cl 1.01-1.01; p=0.009) and requirement of MV (AOR 0.10; 95% 0.02-0.50; p = 0.005).ConclusionGBS patients with bulbar palsy may be managed by nasogastric feeding and nursing in lateral position without increasing the risk of pneumonia. Mechanical ventilation based on ABG does not worsen outcomes of GBS with bulbar palsy.Copyright © 2024 Southern Society for Clinical Investigation. Published by Elsevier Inc. All rights reserved.
