Ventilatory care in myasthenia gravis crisis: assessing the baseline adverse event rate.

Objective: Myasthenic patients who require mechanical ventilation often develop pneumonia or atelectasis. Although there are differences in the prevalence of these complications among various institutions, there is no evidence that aggressive treatment shortens the course of the myasthenic crisis. We have quantified the severity of lung injury and aggressiveness of respiratory intervention in myasthenic patients admitted to the neuro-critical care unit.
