Abstract：
Introduction: Asthma is one of the most common airway diseases that nearly all pediatricians will encounter in their clinical practice. Using spirometry to compare a patient\'s forced expiratory volume in one second (FEV1) both pre- and post-bronchodilator administration is the ideal way to document a paradoxical bronchodilator response.Case Study: Here, we present a patient who experienced paradoxical responses to short acting beta-2 agonists (SABAs; albuterol and levalbuterol).Results: This patient responded to an anti-cholinergic agent (ipratropium bromide) with both subjective as well as objective response.Conclusion: This case highlights the need to include paradoxical response to SABAs in the differential of a patient with poorly controlled asthma. It also provides an example of successful treatment of a pediatric patient with a class of medications previously reserved for adults with chronic obstructive pulmonary disease.
