Background: Weakness in the ICU may be caused by a number of disorders. Guillain-Barré syndrome (GBS) and myasthenia gravis (MG) are examples of conditions that might lead to an ICU admission. The most likely cause of weakness after ICU admission is critical illness polyneuropathy/myopathy (CIP/M).
The most serious complications of myasthenia gravis is a myasthenia crisis. This is a condition of extreme muscle weakness, particularly of the diaphragm and chest muscles that support breathing. Breathing may become shallow or ineffective.
