What are the factors that would lead to a poor prognosis in MG?
Older age and respiratory failure are predictors of poor prognosis in MG [7]. Median duration of hospitalisation for MG crisis is one month. Patients usually spend half of this time intubated in ICU [9].
What effect on mortality does the duration of intubation have?
The duration of intubation is an important short-term predictor of functional outcome after a crisis.
What is the mortality rate for patients in crisis?
Mortality rate during hospitalisation for crisis is approximately 4-8%. This has decreased from nearly 50% in the 1960s [11,13].
