Asthma.

Area of Science:

• Emergency Medicine
• Pulmonology
• Clinical Therapeutics

Background:

• Asthma is a prevalent condition frequently managed in emergency settings.
• Accurate clinical assessment via history and physical examination is crucial for determining asthma severity.
• Objective measures of airway resistance are vital for monitoring treatment efficacy.

Purpose of the Study:

• To outline an effective approach for emergency physicians in managing acute asthma.
• To emphasize the importance of objective measurements in assessing asthma severity and guiding treatment.
• To review current and emerging therapeutic options for acute asthma exacerbations.

Main Methods:

• Initial assessment of airway resistance using FEV1 (Forced Expiratory Volume in 1 second) or PEFR (Peak Expiratory Flow Rate).
• Utilizing inhaled beta-agonists as first-line therapy.
• Considering adjunctive therapies such as aminophylline, anticholinergic agents, and corticosteroids based on severity.
• Employing strict criteria for recognizing and managing severe or potentially fatal asthma (status asthmaticus).

Main Results:

• Objective measures (FEV1/PEFR) provide essential parameters for tracking therapeutic response and identifying severe obstruction.
• Inhaled beta-agonists are effective first-line treatments.
• Anticholinergic agents show promise, particularly in combination with beta-agonists.
• Early corticosteroid use may prevent relapses in severe asthma attacks.
• Aminophylline's role in acute bronchospasm appears limited in the initial hours.

Conclusions:

• A structured, stepwise approach to asthma management in the emergency department improves patient satisfaction and reduces physician errors.
• Objective monitoring of airway resistance is fundamental for effective asthma treatment.
• The judicious use of inhaled beta-agonists, anticholinergics, and corticosteroids is key to managing acute asthma exacerbations.
