Emergency intubation for respiratory failure in Guillain-Barré syndrome.

BACKGROUND: The consequences of emergency intubation in Guillain-Barré syndrome are not known.

OBJECTIVE: To review data from patients admitted to the intensive care unit with recent diagnosis of Guillain-Barré syndrome and intubation for respiratory failure.

DESIGN, SETTING, AND PATIENTS: The database of patients with Guillain-Barré syndrome admitted to the intensive care units during the past 2 decades was reviewed. Emergency intubation was defined as need for ventilation in a patient with sudden dyspnea, cyanosis, or respiratory arrest. Outcome and pulmonary morbidity were assessed by comparing these patients with patients intubated electively.

RESULTS: Six patients were intubated for acute respiratory distress and 1 patient for respiratory arrest. Thirty-six patients were intubated electively. Prolonged weaning was twice as common in the emergent group as in the elective group; a larger sample size might have demonstrated statistical significance. One patient with respiratory arrest developed marked anoxic encephalopathy; in all others, no differences were found in mortality, pulmonary morbidity, or duration of ventilatory assistance. None of the emergency intubations occurred in the last 15 years of the study.

CONCLUSIONS: Emergency intubation in Guillain-Barré syndrome is uncommon but, when associated with respiratory arrest, can lead to anoxic encephalopathy. Duration of ventilator use and pulmonary morbidity are not increased in these patients.
