At present, allergic asthma cannot be cured, but long-term standardized treatment can enable most patients to achieve good or complete clinical control. Glucocorticoids are currently the most effective drugs for asthma control, and inhaled glucocorticoids are currently the drug of choice for long-term asthma treatment because of their strong local anti-inflammatory effects and few systemic adverse effects. Treatment principles: detachment from allergens, bronchodilation and treatment of airway inflammation to relieve asthma attacks and control or prevent asthma attacks. The goal of treatment in the acute exacerbation period is to relieve airway spasm as soon as possible, correct hypoxemia, restore lung function, prevent further deterioration or re-exacerbation, and prevent and treat complications; the goal of treatment in the non-acute period is to prevent another acute asthma attack. 1. Acute exacerbation: ① Immediately get rid of allergens. ② Mild: nebulized inhalation of short-acting β2 agonists, such as salbutamol, terbutaline, intermittent inhalation. If the effect is not good, add slow-release theophylline tablets for oral administration or short-acting anticholinergic aerosol inhalation. ③Moderate: nebulized inhalation of short-acting β2 agonists, combined with inhalation of short-acting anticholinergics, glucocorticoids (such as budesonide, beclomethasone, etc.), and also combined with intravenous theophylline. If it still cannot be relieved, oral glucocorticoids (prednisone, etc.) should be administered as soon as possible, along with oxygen. ④Severe and critical: oxygen; continuous nebulized inhalation of short-acting β2 agonists, combined with inhalation of short-acting anticholinergics, glucocorticoids and intravenous theophyllines; early intravenous application of hormones, to be changed to oral after the condition is controlled and relieved; maintenance of water-electrolyte balance, correction of acid-base imbalance; prevention of respiratory tract infection; if the deterioration of hypoxia cannot be corrected, timely non-invasive or invasive mechanical ventilation. 2, non-acute exacerbation: ① intermittent to mild: inhaled β2 agonist or oral β2 agonist controlled-release tablets according to individual differences, oral small-dose theophylline controlled-release tablets, and also quantitative inhaled small-dose glucocorticoids. ②Moderate: Inhale β2 agonist according to the patient’s condition, and switch to oral β2 agonist controlled-release tablets, oral small-dose theophylline controlled-release tablets, oral leukotriene antagonists (such as Montelukast, etc.), and also quantitative inhalation of small-dose glucocorticoids. ③Severe: regular inhalation of β2 agonist or oral β2 agonist controlled-release tablets and theophylline controlled-release tablets should be taken, or β2 agonist combined with anticholinergics or leukotriene antagonists should be added orally, and glucocorticoids should be inhaled. If symptoms persist, regular oral glucocorticoids are required. The above specific medications should be combined with clinical practice and guided by the doctor’s interview. In the non-acute stage, TCM treatment has advantages. By tonifying the lung, spleen and kidney, it can improve the immunity of the body and prevent and reduce recurrence. In conclusion, allergic asthma is more stubborn and difficult to cure, and active and standardized treatment is crucial.
