The goals of treatment for sudden asthma are to relieve airway spasm as soon as possible, correct hypoxemia, restore lung function, prevent further deterioration or reexacerbation, and prevent complications. Mild acute asthma attack: patients need to be treated promptly with β2 agonists such as salbutamol and terbutaline, or inhaled bronchodilators such as hydroxyzine aerosol. Moderate acute asthma attack: need to be combined with the above drugs to apply beclomethasone propionate, budesonide and other glucocorticoid inhalers. Severe asthma acute attack: it is necessary to cooperate with the doctor to apply glucocorticosteroids such as hydrocortisone succinate and methylprednisolone by intravenous drip or injection, and also need to apply aminophylline, which is needed to relieve airway spasm as soon as possible. Oxygen is also needed to correct hypoxemia, restore lung function and prevent further deterioration, and mechanical ventilation may be needed if necessary. Asthma requires long-term standardized treatment and management, for acute exacerbations of patients are under the guidance of the doctor to develop individualized long-term treatment plan. Patients need to strengthen the management of daily life, carry first aid medication with them, and go to the hospital for follow-up appointments on time.
