Asthma exacerbations treatment

Asthma exacerbations can be classified as mild, moderate, severe, or life threatening. A brief focused history and relevant physical examination should be conducted concurrently with the prompt initiation of therapy, and findings documented in the notes. Features of acute severe asthma ۱- Peak expiratory flow (PEF) less than ۵۰% of best ۲- Talks in word ۳- Respiration ≥۳۰ breaths/min ۴- Pulse ≥۱۲۰ beats/min ۵- O۲ sat (on air)۹۰ ۶- agitated ۷- accessory muscles being used Early treatment is the most effective strategy for managing asthma exacerbations. It is essential to teach patients how to monitor signs and symptoms, and take appropriate action. Patients who have a written asthma action plan and appropriate medication can often manage mild exacerbations at home. The goal of asthma exacerbation treatment is to rapidly relieve airflow obstruction, address hypoxemia, and reduce airway inflammation. The main approach to treating acute asthma exacerbations involves using inhaled bronchodilators, systemic corticosteroids, and supplemental oxygen. Oxygen Therapy: Controlled or titrated oxygen therapy is recommended over high-concentration oxygen. The aim is to maintain oxygen saturation (SpO۲) between ۹۴- ۹۸% Inhaled Beta-۲ Agonists: Rapid-acting inhaled beta-۲ agonists like salbutamol (albuterol) are the first-line treatment. Ipratropium: In some cases, an inhaled anticholinergic like ipratropium may be added to beta-۲ agonists, especially in severe exacerbations. Oral or Intravenous: Systemic corticosteroids, such as oral prednisolone or intramuscular dexamethasone, are recommended to reduce inflammation and improve lung function. Corticosteroids have been shown to reduce mortality, relapses, subsequent hospital admissions, and the need for beta-۲ agonist therapy In severe cases, intravenous magnesium sulfate, Heliox or epinephrine may be considered. Monitoring: Close monitoring of symptoms, respiratory rate, oxygen saturation, and peak expiratory flow (PEF) is crucial. Arterial blood gas measurements may be necessary in severe cases or if the patient is not responding to initial treatment.
