Why is asthma more common in winter? How rationally to stop an asthma attack with medication?
Asthma is a chronic inflammatory condition characterized by (1) airway obstruction, usually reversible; (2) airway hyperreactivity; and (3) bronchial inflammation with epithelial damage, smooth muscle hypertrophy, and mucus blockage. The classification of asthma according to primary irritant that causes or is associated with an exacerbation is useful for both epidemiological and clinical purposes. In this sense, asthma can be divided into allergic asthma and specific asthma (asthma not caused by allergic irritants).
Then, as question shows, one of reasons is that weather is too cold in winter, which increases likelihood of an asthma attack. In addition, in winter, weather and air are dry, which can easily stimulate respiratory tract and cause asthma. Poor people (such as elderly patients, etc.) are also cause of various diseases (not only asthma)!
So let's continue learning more about what "asthma" is and how to control "asthma" with medication! ! clinical suspicion
The clinical picture is very similar to episodes of wheezing, shortness of breath, coughing, chest tightness and a feeling of suffocation in neck. Attacks usually occur at night or upon awakening, but can occur at any time of day.
diagnosis
Requires spirometry, which is defined as an improvement in obstructive pattern following bronchodilator therapy. Improvement was defined as a 12% increase in FEV1 or a 35% increase in forced expiratory flow (FEF).
treatmentStep-by-Step Approach:
Step 1: Take a Light RestPatients do not have daily seizures and do not wake up at night.
The second step is soft and continuous
Treatment A. disease-modifying drugs is necessary for patients with daily symptoms or daily use of bronchodilators.
The third step is seriously preserved
The patient had severe symptoms and inadequate control despite use of high doses of inhaled corticosteroids (>20 puffs of beclomethasone, triamcinolone acetonide, or flunaractone per day)
modified chronic therapy
Treatment is reviewed every 1 to 6 months and gradual dose reduction may be considered. Assess for possible signs and symptoms of corticosteroid withdrawal at weaning in patients taking inhaled steroids.
If control is not maintained, check patient management, adherence, and environmental control (avoidance of allergens or other factors that contribute to asthma severity). It may be necessary to add control (anti-inflammatory) therapy with addition of long-acting beta-agonists.
