Reason 1: the survey shows that about 12% - 20% of the newborns born to mothers with myasthenia gravis suffer from myasthenia gravis. They usually have signs at birth, often combined with difficulty in sucking and swallowing. They have no duty to cry, and need assisted breathing when they have difficulty breathing. The eyelids are drooping, the facial muscles are not responsible, and the expression is poor.

There is no acetylcholine receptor antibody in sick infants, and its pathogenesis is related to heredity. The structure of postsynaptic membrane was abnormal, the functional junction fold was almost completely absent, the microstructure was reduced, and the acetylcholine receptor of endplate was insufficient.

If more than 10 times, you need to increase the weight of the equipment; or if more than 10 times, you need to increase the weight of the equipment.
