The anesthetic precautions for myasthenia gravis are as follows: First, we should pay attention to the duration of anesthesia, which should not be too long, because patients with myasthenia gravis have dulled muscle sensation, and if the anesthesia is too long, it is likely to cause muscle damage, and in serious cases, muscle atrophy, and prolonged anesthesia for patients with myasthenia gravis will cause further damage to the nerves, which may aggravate the symptoms of myasthenia gravis. The second thing to note is that the amount of drugs used should not be too large, that is, the amount of anesthetics each time, should be less than normal patients, because the muscle and nerve function of patients with myasthenia gravis itself is somewhat reduced, if the amount of drugs used is larger, it may cause further damage to the muscle nerves. Besides, try to use anesthetics with less side effects when using anesthetics to reduce the damage to the nerves and muscles, thus playing a role in protecting the nerve muscles.
