Bronchial Thermoplasty: A Novel Therapeutic Approach to Severe Asthma
Published on: November 4, 2010
Insights
Severe childhood asthma is a growing concern, requiring prompt recognition and aggressive treatment. This review covers the epidemiology, pathophysiology, and acute care of pediatric asthma exacerbations to improve patient outcomes.
Area of Science:
- Pediatric Pulmonology
- Emergency Medicine
Background:
- Childhood asthma incidence and severity are increasing despite advances in therapy.
- Asthma exacerbations involve vasoactive substances triggering bronchospasm, edema, and mucus plugging.
Observation:
- Severe asthma attacks pose significant risks, including life-threatening complications.
- Early symptom recognition is crucial for effective management.
Findings:
- Prompt, aggressive treatment with oxygen, bronchodilators, corticosteroids, and anticholinergics is essential.
- Severe cases may necessitate intubation, mechanical ventilation, and anesthetic agents.
Implications:
- Understanding asthma pathophysiology guides acute care strategies.
- Effective management of pediatric asthma exacerbations can reduce morbidity and mortality.
Abstract:
Severe childhood asthma is a serious, life-threatening disease that presents a challenge for patients, families, and caregivers. Despite evolving medical and pharmacologic therapies, the incidence and severity of asthma are increasing. Vasoactive substances are released in response to environmental and intrinsic triggers and result in bronchospasm, bronchial mucosal edema, and mucus plugging of the airways. Early recognition of symptoms and prompt, aggressive treatment, including oxygen, beta agonists, corticosteroids, and anticholinergic agents, are essential in halting the progression of asthma symptoms. In the most severe cases, intubation, mechanical ventilation, and treatment with anesthetic agents may be needed to avoid significant morbidity and mortality. This article reviews epidemiology, pathophysiology, and acute care of the child experiencing an acute asthma exacerbation.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
