Bronchodilators for bronchiolitis

1999
Bronchiolitis is an acute, highly communicable lower respiratory tract infection. Bronchodilators are commonly used in the management of bronchiolitis in North America, but not in the United Kingdom. The objective of this review was to assess the effects of bronchodilators for bronchiolitis.We searched MEDLINE, EMBASE, Reference Update, reference lists

Respiratory impedance and bronchodilator responsiveness in healthy children aged 2–13 years

Pediatric Pulmonology, 2013
The forced oscillation technique (FOT) can be used in children as young as 2 years of age and in those unable to perform routine spirometry. There is limited information on changes in FOT outcomes in healthy children beyond the preschool years and the ...

Anticholinergic Bronchodilators

1998
Publisher Summary Cholinergic bronchomotor activity can be reflexly augmented by a variety of stimuli through the neural pathways. In human airways, the bulk of efferent autonomic nerves are cholinergic. Branches of the vagus nerve travel along the airways and synapse at peribronchial ganglia, from which short postganglionic nerves travel to smooth ...

A Paradoxical Effect of Bronchodilators

Chest, 1997
Lactic acidosis previously has been reported during treatment of asthma with beta-2 agonists. However, this metabolic disturbance never had any clinical consequence. We report a case of a patient with asthma in whom beta-2 agonist administration increased dyspnea by metabolic acidosis due to a sharp increase in lactate levels (hyperlactatemia) and led ...

Beta-Adrenergic Bronchodilators [PDF]

Respiration, 1986
Long-acting beta 2-selective agonists have become a major form of therapy of reversible airway obstruction. Modern agents are effective by all routes of administration and can both eliminate bronchospasm as well as prevent its occurrence. Many drugs such as albuterol, terbutaline and fenoterol have similar pharmacologic profiles, and there is ...

Anticholinergic bronchodilators in combination

Expert Opinion on Pharmacotherapy, 2000
Chronic obstructive pulmonary disease (COPD), which affects approximately 14 million Americans, is the fourth leading cause of death in the United States and is responsible for an estimated US$6.5 billion in direct and indirect costs per year [1,2]. Its usual course is a slow deterioration of lung function and progressive breathlessness with activities.

Assessing bronchodilator responsiveness

Journal of Allergy and Clinical Immunology, 1977
This report concerns the difficulty in distinguishing variation due to drug effects from the spontaneous daily variation in baseline levels of pulmonary function in the evaluation of bronchodilator responsiveness in asthmatic children. Both prospective and retrospective studies were employed to assess the importance of the influence of the baseline ...

Regional Lung Deposition and Bronchodilator Response as a Function of β2-Agonist Particle Size

, 2005
Rationale: Aerosol particle size influences the extent, distribution, and site of inhaled drug deposition within the airways.Objectives: We hypothesized that targeting albuterol to regional airways by altering aerosol particle size could optimize inhaled

Evaluating bronchodilator effects in chronic obstructive pulmonary disease using diffusion-weighted hyperpolarized helium-3 magnetic resonance imaging.

Journal of applied physiology, 2012
The objective of this study was to evaluate the regional effects of bronchodilator administration in chronic obstructive pulmonary disease (COPD) using hyperpolarized helium-3 ((3)He) MRI apparent diffusion coefficient (ADC). Ten COPD ex-smokers provided
