Best treatments for bronchial spasm

Understanding bronchial spasm

"Bronchial spasm" (bronchospasm) is a mechanism, not a diagnosis — which is why the term feels odd. StatPearls (NCBI Bookshelf), in its Pediatric Bronchospasm review, defines it as constriction of the smooth muscle layers of the small airways: the airway squeeze that produces wheeze, and that sits underneath several different diseases. That review names acute asthma exacerbation, acute viral bronchiolitis and anaphylaxis as disease processes that induce bronchospasm in the pediatric population, so the question that matters is never "is this bronchospasm" but "what is driving it." Per the same StatPearls review, the child may complain of chest tightness, shortness of breath or cough, and exam clues are accessory respiratory muscle use, nasal flaring, tachypnea and a prolonged expiratory phase; with air trapping from the obstruction, patients are at higher risk for pneumothoraces and pneumomediastinum. One form has a diagnostic definition of its own: exercise-induced bronchoconstriction (EIB), which StatPearls (NCBI Bookshelf) defines as narrowing of the airways during or shortly after physical activity. StatPearls puts the threshold at a fall in FEV1 of 10% or more, which confirms the diagnosis, with severity classified as mild (10% to under 25%), moderate (25% to 50%) or severe (over 50%) — and reports that EIB occurs in 40% to 90% of individuals with asthma and up to 20% of the general population without asthma. Two things get missed. MedlinePlus (NLM) notes that most people with asthma have EIB, but not everyone with EIB has asthma — and that most times symptoms start soon after you stop exercising, though some people have symptoms while they are exercising. StatPearls adds that bronchoconstriction peaks within 10 to 15 minutes and typically resolves within 30 to 90 minutes, followed by a refractory period of 1 to 3 hours.
