Myasthenia Gravis, a type of immune inflammatory disease of the nervous system, is mainly caused by the production of abnormal antibodies in the body. Myasthenic crisis can endanger the life safety of patients, affecting respiratory function. There are mainly three types of crises: The first type of crisis is the myasthenic crisis, which is also the most common. Generally, it is caused by the progression of the disease itself, often due to insufficient anticholinesterase drug dosage.

The second type of crisis is the cholinergic crisis, caused by an overdose of anticholinesterase drugs, resulting in symptoms like muscle tremors in patients.

The third type is the paradoxical crisis, which occurs due to insensitivity to anticholinesterase drugs, leading to severe respiratory difficulties. It is essential to handle a myasthenic crisis promptly, maintain the patient's airway clearance, and use a ventilator for treatment if necessary.
