Use of adrenergic bronchodilators by pediatric allergists and pulmonologists
1Pediatric Allergy and Pulmonology Service, Merrillville, IN 46410.
Insights
Pediatricians commonly use inhaled adrenergic bronchodilators for children with respiratory conditions across various settings. Expert practice shows flexibility in dosing, with inhaled albuterol, metaproterenol, or terbutaline sulfate being preferred choices.
Area of Science:
- Pediatric Pulmonology
- Allergy and Immunology
Background:
- Adrenergic bronchodilators are crucial for managing pediatric respiratory conditions.
- Understanding expert physician practices is key to optimizing treatment guidelines.
Purpose of the Study:
- To investigate current pediatric specialist practices regarding adrenergic bronchodilator use in children.
- To identify preferred agents, settings, and dosing strategies for pediatric bronchodilator therapy.
Main Methods:
- Survey of 21 pediatricians specializing in allergy, pulmonology, or both.
- Inquiry into the use of adrenergic bronchodilators across different age groups and clinical settings (home, ED, hospital).
Main Results:
- Most pediatricians utilize inhaled bronchodilators for all ages and settings.
- Inhaled albuterol, metaproterenol, and terbutaline sulfate are frequently preferred.
- Dosing intervals are adjusted based on clinical setting, with shorter intervals common in emergency and hospital care.
- Significant variation exists in the use of specific agents and intravenous administration.
Conclusions:
- Expert pediatricians demonstrate varied but generally consistent approaches to adrenergic bronchodilator therapy.
- Inhaled medications are favored across settings and ages, with flexible dosing.
- Further standardization may improve outcomes for pediatric asthma, bronchopulmonary dysplasia, and bronchiolitis.
Abstract:
Twenty-one pediatricians specializing in allergy, pulmonology, or both were questioned about their use of adrenergic bronchodilators for treating children of different ages at home, in the emergency department, and in the hospital. Most would use inhaled medications in all settings and for all ages. Few expressed strong preference for one drug over another, but only 2 would regularly use nebulized isoproterenol hydrochloride or isoetharine hydrochloride. Dosing frequency of inhaled medication at home was usually limited to every 4 hours, but in the emergency department or hospital, intervals between doses of 20 minutes or less were common. If this treatment failed, 9 physicians would use intravenous isoproterenol, but 4 strongly opposed its use. These results indicate that substantial variation exists in current expert practice, but that inhaled albuterol, metaproterenol, or terbutaline sulfate are most often preferred for treating asthma, bronchopulmonary dysplasia, and bronchiolitis in children of all ages, and that doses and dosing intervals are frequently altered to meet patient needs.

Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...

Vasopressor or pressor agents: They increase blood pressure and function as cardiac stimulants. Examples include endogenous catecholamines (norepinephrine and dopamine) and synthetic agents (phenylephrine).

Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
