The anesthesia for mandibular angle surgery should be general anesthesia with tracheal intubation. After anesthesia induction, a catheter needs to be inserted from the mouth to enter the trachea. The patient did not breathe spontaneously during anesthesia, so an anesthesia machine was needed to supply oxygen to the lungs through this tube to meet the needs of life during operation.

Asthmatic patients are prone to airway spasm after anesthesia induction and tracheal intubation, that is, asthma attack. At this time, it will be very dangerous. The patient can't breathe on his own, but he can't supply oxygen to his lungs. If it is not relieved in time, the patient will suffer from hypoxia, suffocation and even death.

Oral glucocorticoid, namely dexamethasone tablets, can not reduce the probability of airway spasm during operation, and at the same time conceal the medical history, which will cause doctors to be caught off guard and take remedial measures to further increase the risk.

It's not alarmist, it's human life.
