What is the role of epinephrine (adrenaline) in treating life-threatening refractory Chronic Obstructive Pulmonary Disease (COPD) exacerbations?

From the Guidelines

Epinephrine should not be used as a primary treatment for life-threatening refractory Chronic Obstructive Pulmonary Disease (COPD) exacerbations, but rather as a last-resort option in a closely monitored setting, due to its potential to cause significant cardiovascular side effects and the availability of other more effective and safer treatments. The most recent and highest quality evidence from the European Respiratory Society/American Thoracic Society guideline 1 and the Global Initiative for Chronic Obstructive Lung Disease (GOLD) report 1 emphasizes the importance of maximizing standard treatments, such as inhaled bronchodilators, systemic corticosteroids, and oxygen therapy, before considering other interventions. Key considerations for managing COPD exacerbations include:

• Using short-acting inhaled β2-agonists, with or without short-acting anticholinergics, as the initial bronchodilators 1
• Administering systemic corticosteroids to improve lung function and shorten recovery time 1
• Prescribing antibiotics when indicated to reduce the risk of early relapse and treatment failure 1
• Utilizing non-invasive ventilation (NIV) as the first mode of ventilation in patients with acute respiratory failure 1 If epinephrine is considered, it is crucial to:

1. Ensure standard treatments have been maximized.
2. Consider other interventions like non-invasive ventilation or intubation. Precautions for epinephrine use include:

• Monitoring heart rate, blood pressure, and ECG closely.
• Using with extreme caution in patients with cardiovascular disease.
• Being prepared to manage potential side effects like tachycardia, hypertension, or arrhythmias. The justification for this approach lies in the potential benefits of epinephrine as a bronchodilator and its ability to reduce airway edema, but also in the need to carefully weigh these benefits against the risks of cardiovascular side effects, particularly in a population already at high risk for cardiovascular disease 1.

From the Research

Role of Epinephrine in Treating Life-Threatening Refractory COPD Exacerbations

• There is no direct mention of the role of epinephrine (adrenaline) in treating life-threatening refractory Chronic Obstructive Pulmonary Disease (COPD) exacerbations in the provided studies 2, 3, 4, 5, 6.
• The studies focus on various treatments for COPD exacerbations, including pharmacological and non-pharmacological approaches, such as inhaled bronchodilators, steroids, antibiotics, oxygen therapy, non-invasive mechanical ventilation, and pulmonary rehabilitation 2, 3, 4, 5, 6.
• The use of epinephrine is not mentioned as a treatment option for COPD exacerbations in any of the provided studies.
• The management of refractory COPD is discussed in study 3, which highlights the need for a multidimensional approach, including ensuring adequate inhaler techniques, exploring the need for non-invasive ventilatory support, and using chronic antibiotics and phosphodiesterase inhibitors.
• Study 5 discusses the use of noninvasive ventilation in the treatment of acute exacerbation of COPD, but does not mention epinephrine as a treatment option.
• Study 6 provides guidance on managing COPD exacerbations in primary care, including the use of short-acting bronchodilators, antibiotics, and oral prednisolone, but does not mention epinephrine.
