AI Article Synopsis
- Paradoxical bronchospasm is a rare response where the airways constrict after using bronchodilators like beta-agonist inhalers, which usually help relieve asthma symptoms.
- Although these medications are designed to relax bronchial muscles, some patients may experience increased respiratory distress or even failure following treatment.
- A case is presented of a male asthma patient who experienced worsening symptoms immediately after taking fenoterol (Berotec®) for wheezing, highlighting the need for awareness of this potential side effect.
Article Abstract
Paradoxical bronchospasm refers to the constriction of the airways after treatment with a sympathomimetic bronchodilator. Theoretically, bronchodilators, such as beta-agonist inhalers, act to ease asthma symptoms by relaxing the muscles surrounding the walls of the bronchial tubes, which relieve bronchial constriction. However, in rare instances, some patients develop respiratory distress or even respiratory failure after inhaled bronchodilator use, although the exact mechanism for this adverse effect is unknown. We report a male, with a known asthma history diagnosed for more than one decade, receiving fenoterol (Berotec®) for wheezing control and the worsening of his clinical condition immediately after bronchodilator administration.

Exercise-Induced Asthma: Managing Respiratory Issues in Athletes.
J Funct Morphol Kinesiol

Division of Respiratory Medicine, University Hospital "Tor Vergata", 00133 Rome, Italy.
Article Synopsis
- - Asthma affects millions globally and is especially prevalent among elite athletes, with respiratory conditions like exercise-induced bronchoconstriction (EIB) affecting 20% to 70% of them, depending on the sport and other factors.
- - EIB can impact athletic performance as exercise triggers asthma symptoms, but regular physical activity may also enhance lung function; however, athletes with asthma may exhibit different responses to treatment due to unique factors like airway sensitivity and environmental exposure.
- - Diagnosing EIB requires specific tests since standard lung function tests may appear normal; exercise tests are particularly effective, distinguishing between EIB with asthma (EIBA) and without asthma (EIBwA).
Evaluating efficacy and safety of sub-anesthetic dose esketamine as an adjuvant to propofol/remifentanil analgosedation and spontaneous respiration for children flexible fibreoptic bronchoscopy: a prospective, double-blinded, randomized, and placebo-controlled clinical trial.

Flexible fiberoptic bronchoscopy (FFB) for children is widely performed under sedation. Currently, the optimal sedation regimen remains unclear. Esketamine is an N-methyl-D-aspartic acid (NMDA) receptor antagonist, which has stronger sedative and analgesic effects and exerts less cardiorespiratory depression than other sedatives.

Article Synopsis
- Inhaled short-acting β-adrenergic agonists can rarely cause paradoxical bronchospasm (PB), which can be serious, and this study aimed to assess its occurrence in veterans with COPD or asthma.
- Of 1,150 spirometry test reports reviewed from 2017-2020 at the Jesse Brown VA Medical Center, 18 cases of post-bronchodilator PB were identified, mainly affecting older male patients with a significant history of smoking.
- The researchers found that while no reports explicitly noted PB, the data suggested a need for better recognition and reporting of this phenomenon, given its clinical relevance in treating respiratory conditions.
