Albuterol and Croup: A Review of Current Research
Introduction to Croup and Albuterol
Croup, a common respiratory condition in children, is characterized by a distinctive barking cough and stridor due to upper airway inflammation. Albuterol, a bronchodilator primarily used for asthma, has been explored for its potential benefits in treating croup. This article synthesizes recent research on the use of albuterol in managing croup, highlighting key findings and clinical implications.
Efficacy of Albuterol in Croup Management
Limited Evidence for Albuterol in Croup
Research indicates that albuterol is not commonly recommended for croup management. A study comparing emergency medical services protocols across the United States found that while albuterol is widely used for bronchospasm and generalized respiratory distress, it is not a standard treatment for croup2. This suggests that albuterol's role in croup management is limited and not well-supported by current protocols.
Comparison with Other Treatments
In contrast to albuterol, other treatments such as nebulized budesonide and oral dexamethasone have shown significant efficacy in improving clinical outcomes for croup patients. These treatments reduce the need for hospitalization and provide acute clinical improvement1. Additionally, the use of racemic epinephrine in emergency settings has been effective in managing croup symptoms without necessitating automatic hospital admission1.
Variability in Emergency Management Practices
Physician Training and Treatment Choices
A study examining the emergency management of croup revealed significant variability in treatment practices based on physician training backgrounds. Emergency medicine (EM) practitioners were more likely to use albuterol, racemic epinephrine, and parenteral steroids compared to pediatricians (PED) and pediatric emergency medicine specialists (PEM)4. This variability underscores the need for standardized treatment protocols to ensure consistent and effective care for croup patients.
Protocol Differences Across States
There is also considerable variation in prehospital protocols for managing pediatric respiratory distress, including croup. While albuterol is consistently recommended for wheezing, its use in croup protocols is less common, with only a few states including it as a treatment option2. This inconsistency highlights the need for further research and evidence-based guidelines to optimize croup management.
Conclusion
Current research suggests that albuterol is not a primary treatment for croup, with limited evidence supporting its efficacy in this context. More effective treatments, such as nebulized budesonide, oral dexamethasone, and racemic epinephrine, are preferred for managing croup symptoms. The variability in treatment practices based on physician training and state protocols indicates a need for standardized guidelines to ensure optimal care for children with croup. Further studies are necessary to explore the potential role of albuterol and to refine treatment protocols for this common pediatric condition.

Observational StudyInfluence of albuterol, cromolyn sodium and ipratropium bromide on the airway and circulating mediator responses to allergen bronchial provocation in asthma.
Albuterol and cromolyn sodium effectively reduce airway responses to allergens, while ipratropium bromide may increase mast cell mediator release in asthmatic patients.

Emergency medicine-trained physicians use more resources and longer ED visits compared to pediatricians in managing uncomplicated cases of croup.
Observational StudyThe effect of cromolyn sodium and albuterol on early and late phase bronchoconstriction and airway leukocyte infiltration after allergen challenge of nonanesthetized guinea pigs.
Cromolyn sodium effectively inhibits early and late asthmatic responses and reduces leukocyte infiltration in airways, while albuterol partially reverses late asthmatic responses but has no other significant effects.

Oral albuterol does not reduce the frequency or duration of acute cough in non-asthmatic children with a normal chest examination.

Nebulized epinephrine improves croup score in children and shortens hospital stay, but its effectiveness varies by racemic and isomer, and whether it is administered via IPPB or nebulization alone.
